[0058] The present disclosure is considered as an exemplification of various inventions and is not intended to be limited to the specific embodiments set forth in the drawings or the following description.

[0059] Now refer to Figures 1A to 1DAccording to an exemplary embodiment of the present disclosure, a simplified version of the leg actuator mechanism is provided. As shown in the figure, various embodiments of the leg actuator mechanism include a thigh mechanism 1, a calf mechanism 5, a mounting member 2, an upper follower connection member 3 and a lower follower connection member 4.

[0060] In various embodiments, the mounting member 2 defines a follower path configured to receive a follower joint C1. As shown, the upper follower connector 3 and the lower follower connector 4 are operably coupled at the follower joint C1. For example, a first upper follower end of the upper follower connector 3 can be operably coupled to a first lower follower end of the lower follower connector 4 at the follower joint C1. In various embodiments, the upper follower connector 3 can be attached to the thigh mechanism 1 at a second upper follower end (e.g., end at joint B1) between a hip end (e.g., end at hip joint A) of the thigh mechanism 1 and a knee end (e.g., end at lower knee joint B2) of the thigh mechanism 1. In various embodiments, the lower follower connector 4 can be attached to the calf mechanism 5 at a second lower follower end (e.g., end at joint C2) between a first end (e.g., lower knee joint B2) and a second end (e.g., heel joint D) of the calf mechanism 5. In some embodiments, the thigh mechanism 1 and the calf mechanism 5 may be operably coupled at the lower knee joint B2.

[0061] In various embodiments, as the follower joint C1 moves around the follower path 2, the upper follower connection 3 and the lower follower connection 4 move, and in accordance with these movements, the thigh mechanism 1 and the calf mechanism 5 also move around the lower knee joint B2 between different degrees of bending and straightening positions.

[0062] Now refer to Figure 1A , the leg actuator mechanism is in a first position so that the follower joint C1 is located at the bottom of the follower path 2. In this embodiment, with the follower joint C1 located at the bottom of the follower path, the angle defined between the thigh mechanism and the shank mechanism may be greater than 90 degrees. In some embodiments, the angle defined between the thigh mechanism and the shank mechanism may be greater than 120 degrees. In some embodiments, the angle defined between the thigh mechanism and the shank mechanism may be greater than 150 degrees. In some embodiments, the angle defined between the thigh mechanism and the shank mechanism may be slightly less than 180 degrees (e.g., between 150 and 180 degrees).

[0063] In some embodiments, the angle defined between the thigh mechanism 1 and the lower mechanism 5 may be substantially the same as the angle defined between the thigh mechanism 1 and the upper follower connection 3 (e.g., the angle defined between the joint A, the joint B1, and the joint C1). In addition, in some embodiments, the angle defined between the thigh mechanism 1 and the upper follower connection 3 (e.g., the angle defined between the joint A, the joint B1, and the joint C1) may be substantially the same as the angle defined between the lower follower connection 4 and the shank mechanism (e.g., the angle defined between the joint C1, the joint C2, and the joint D).

[0064] Now refer to Figure 1B , as the follower joint C1 travels clockwise along the follower path 2, the leg actuator mechanism moves to the second position. As the leg actuator mechanism moves from the first position to the second position, the angle defined between the thigh mechanism and the shank mechanism may only decrease slightly (e.g., less than 30 degrees). In some embodiments, the combination of the thigh mechanism 1 and the shank mechanism 5 may rotate about the hip joint A (e.g., the hip joint A may be stationary).

[0065] Now refer to Figure 1C As the follower joint C1 continues to move along the follower path 2, the leg actuator mechanism moves to the third position (for example, in the third position, the follower joint C1 may be located at the follower joint position in the first position (for example, Figure 1A As the follower joint C1 moves from the second position ( Figure 1B ) moves to the third position ( Figure 1C ), the lower follower connector 4 moves the calf mechanism 5 so that the angle defined between the thigh mechanism 1 and the calf mechanism 5 can be reduced from the angle defined in the first position and / or the second position. For example, the angle defined between the thigh mechanism and the calf mechanism can be less than 120 degrees. In some embodiments, the angle defined between the thigh mechanism and the calf mechanism can be less than 90 degrees. In some embodiments, the angle defined between the thigh mechanism and the calf mechanism can be less than 60 degrees.

[0066] Now refer to Figure 1D , as the follower joint C1 continues to move along the follower path 2, the leg actuator mechanism moves to the fourth position. In various embodiments, as the follower joint C1 travels along the follower path 2, the angle defined between the thigh mechanism and the shank mechanism can increase from the third position. In some embodiments, the angle defined between the thigh mechanism and the shank mechanism can be the same at the fourth position as it was at the second position (e.g., the heel joint D rotates about the hip joint A). In various embodiments, as the follower joint C1 is driven about the follower path 2 (e.g., such as discussed below), the leg actuator mechanism can rotate through Figures 1A to 1D Each position shown (see also as another example Figure 1E to Figure 1H ).

[0067] In various embodiments, the follower path may define an elliptical path. In some embodiments, the placement of the heel joint D may be based on the follower joint C1 being positioned in the follower path 2 along a first direction (e.g., along Figure 1A In various embodiments, the angle defined between the thigh mechanism 1 and the shank mechanism 5 can be based on the position of the follower joint C1 in the follower path 2 along the second direction (e.g., along Figure 1A In various embodiments, the first direction and the second direction may be spaced approximately 90 degrees apart from each other (eg, the first direction and the second direction may form approximately a right angle). Figure 1A The first and second directions discussed are generally horizontal and vertical, respectively, but the axis may be rotated so that the first direction is not along the horizontal axis and / or the second direction is not along the vertical axis. In various embodiments, the first and second directions may be defined based on the position of A relative to the follower path. For example, joint A may be in the first direction relative to the follower path (e.g., joint A may be a fixed pivot point of the leg actuator mechanism).

[0068] In further exemplary embodiments, the follower path may be defined by a swivel mount. Figure 1E to Figure 1H According to an exemplary embodiment of the present disclosure, a simplified version of a leg actuator mechanism with a rotating mount is provided. Figure 1E to Figure 1H , various embodiments of the exemplary leg actuator mechanism illustrated include a thigh mechanism 1 , a shank mechanism 5 , an upper follower connection 3 , a lower follower connection 4 , a follower joint C1 , a follower joint connection Z3 , and a swivel mount 12 .

[0069] In various embodiments, the rotating mount 12 defines a rotating follower path that is configured to drive the follower joint C1 to travel according to the follower path defined by the rotating mount 12 (e.g., along the follower path). In various embodiments, the path is defined along the periphery of the rotating mount 12. For example, the rotating mount 12 may include a disk, wherein the path is defined along the periphery of the disk. As shown, the first end of the follower joint connector Z3 may be operably coupled to both the upper follower connector 3 and the lower follower connector 4 at the follower joint C1. In various embodiments, the follower joint C1 may include an attachment member (e.g., a pin and / or the like) that is configured to couple the follower joint connector Z3 and the upper follower connector Z3 at the follower joint C1.

[0070] A protruding member Z4 (e.g., a pin, a rod, and / or the like) coupled to the rotating mount 12 may extend through at least a portion of an opening defined by the follower joint connector Z3 and may be configured to drive the follower joint connector Z3 in a swinging manner as the mount 12 rotates. For example, the opening defined by the follower joint connector Z3 may allow the rotational movement of the mount 12 to cause the bottom end of the follower joint connector Z3 to swing. The rotating mount 12 may be configured to rotate around the axis of the rotating mount member Z2. The rotating mount member Z2 may include an axis, a shaft, or the like. In various embodiments, the follower joint connector Z3 may include and / or may form a clockwise and / or counterclockwise actuator that swings horizontally.

[0071] As further shown, the second end of the follower joint connector Z3 can be operably coupled to the vertical moving member Z1. The follower joint connector Z3 can be operably coupled to the mounting plate assembly 6 configured as a part of the leg actuator mechanism. The vertical member Z3 can be operably coupled to the mounting plate assembly 6 via an attachment mechanism Z5 (e.g., a pin and / or the like). The vertical moving member Z1 may include or may form a vertical up and down actuator. In various embodiments, the vertical moving member Z1 may be configured to move up and down as the mounting member 12 rotates. As shown in the figure, in some embodiments, the vertical moving member Z1 may have a limited range of motion (e.g., Z1 minimum to Z1 maximum). Within the limited range of motion, the position of the vertical moving member Z1 may depend on the position of the rotating mounting member 12. As described above, the upper follower connector 3 can be coupled to the follower joint connector Z3 at the follower joint C1, and the follower joint Z3 can be coupled to the vertical moving member Z1. In various embodiments, as the mount 12 rotates, the follower joint connection Z3 and the vertical moving member Z1 are caused to move according to their respective movements, which in turn drive or cause the follower joint C1 (and therefore, the upper follower connection 3) to move according to the follower path defined by the rotating mount 12.

[0072] As described above, the rotating mount 12 may be configured to drive the follower joint C1 to travel according to the follower path defined by the mount 12. For example, as the mount 12 rotates, the follower joint C1 may remain tangential to the follower path defined by the rotating mount 12. As described above, the upper follower connector 3 and the lower follower connector 4 may be operably coupled at the follower joint C1. For example, a first upper follower end of the upper follower connector 3 may be operably coupled to a first lower follower end of the lower follower connector 4 at the follower joint C1. In various embodiments, the upper follower connector 3 may be attached to the thigh mechanism 1 at a second upper follower end (e.g., an end at the joint B1) between the hip end of the thigh mechanism 1 (e.g., an end at the hip joint A) and the knee end of the thigh mechanism 1 (e.g., an end at the lower knee joint B2). In various embodiments, the lower follower link 4 can be attached to the calf mechanism 5 at a second lower follower end (e.g., the end at joint C2) between a first end (e.g., lower knee joint B2) and a second end (e.g., heel joint D) of the calf mechanism 5. In some embodiments, the thigh mechanism 1 and the calf mechanism 5 can be operably coupled at the lower knee joint B2.

[0073] In various embodiments, as the follower joint C1 travels according to the follower path defined by the swivel mount 12, the thigh mechanism 1 and the shank mechanism 5 also move about the lower knee joint B2 between different degrees of flexion and straightening positions.

[0074] Now refer to Figure 1E , the leg actuator mechanism is in the first position so that the follower joint C1 is located at the bottom of the follower path defined by the rotating mount 12. In this embodiment, when the follower joint C1 is located below the follower path defined by the rotating mount 12, the angle defined between the thigh mechanism and the shank mechanism can be greater than 90 degrees. In some embodiments, the angle defined between the thigh mechanism 1 and the shank mechanism 5 can be greater than 120 degrees. In some embodiments, the angle defined between the thigh mechanism 1 and the shank mechanism 5 can be greater than 150 degrees. In some embodiments, the angle defined between the thigh mechanism 1 and the shank mechanism 5 can be slightly less than 180 degrees (for example, between 150 degrees and 180 degrees).

[0075] In some embodiments, the angle defined between the thigh mechanism 1 and the shank mechanism 5 may be substantially the same as the angle defined between the thigh mechanism 1 and the upper follower connection 3 (e.g., the angle defined between the joint A, the joint B1, and the joint C1). In addition, in some embodiments, the angle defined between the thigh mechanism 1 and the upper follower connection 3 (e.g., the angle defined between the joint A, the joint B1, and the joint C1) may be substantially the same as the angle defined between the lower follower connection 4 and the shank mechanism (e.g., the angle defined between the joint C1, the joint C2, and the joint D).

[0076] Now refer to Figure 1F , the leg actuator mechanism moves to the second position as the mounting member 12 rotates clockwise, causing the follower joint C1 to travel clockwise according to the follower path defined by the mounting member 12. As the leg actuator mechanism moves from the first position to the second position, the angle defined between the thigh mechanism and the shank mechanism may only decrease slightly (e.g., less than 30 degrees). In some embodiments, the combination of the thigh mechanism 1 and the shank mechanism 5 may rotate about the hip joint A (e.g., the hip joint A may be stationary).

[0077] Now refer to Figure 1G As the mounting member 12 continues to rotate, causing the follower joint C1 to continue to move according to the follower path defined by the mounting member 12, the leg actuator mechanism moves to the third position. (For example, in the third position, the follower joint C1 may be located directly above the follower joint position in the first position, such as Figure 1E As the follower joint C1 moves from the second position ( Figure 1F ) moves to the third position ( Figure 1G ), the lower follower connector 4 moves the calf mechanism 5 so that the angle defined between the thigh mechanism 1 and the calf mechanism 5 can be reduced from the angle defined in the first position and / or the second position. For example, the angle defined between the thigh mechanism 1 and the calf mechanism 5 can be less than 120 degrees. In some embodiments, the angle defined between the thigh mechanism 1 and the calf mechanism 5 can be less than 90 degrees. In some embodiments, the angle defined between the thigh mechanism 1 and the calf mechanism 5 can be less than 60 degrees.

[0078] Now refer to Figure 1H, as the mount 12 continues to rotate, causing the follower joint C1 to continue to travel according to the follower path defined by the mount 12, the leg actuator mechanism moves to the fourth position. In various embodiments, as the follower joint travels according to the follower path defined by the mount 12, the angle defined between the thigh mechanism and the shank mechanism can increase from the third position. In some embodiments, the angle defined between the thigh mechanism and the shank mechanism can be the same at the fourth position as it is at the second position (e.g., the heel joint D rotates about the hip joint A). In various embodiments, as the follower joint is driven to travel according to the follower path defined by the mount 12 (e.g., such as discussed below), the leg actuator mechanism can rotate through Figure 1E to Figure 1H Each location shown.

[0079] In various embodiments, the follower path may define an elliptical path. In various embodiments, the follower path may define a non-elliptical path. In some embodiments, the placement of the heel joint D may be based on the follower joint C1 being positioned in the follower path 2 along a first direction (e.g., along Figure 1E In various embodiments, the angle defined between the thigh mechanism 1 and the shank mechanism 5 can be based on the position of the follower joint C1 in the follower path 2 along the second direction (e.g., along Figure 1E In various embodiments, the first direction and the second direction may be spaced approximately 90 degrees apart from each other (eg, the first direction and the second direction may form approximately a right angle). Figure 1E The first and second directions discussed are generally horizontal and vertical, respectively, but the axis may be rotated so that the first direction is not along the horizontal axis and / or the second direction is not along the vertical axis. In various embodiments, the first and second directions may be defined based on the position of A relative to the follower path. For example, joint A may be in the first direction relative to the follower path (e.g., joint A may be a fixed pivot point of the leg actuator mechanism).

[0080] Now refer to FIG. 2A to FIG. 2B According to an exemplary embodiment of the present disclosure, the components shown in the leg actuator mechanism approximate the human body. As shown, the hip joint A corresponds to the pelvis and / or hip area of ​​the human body. In various embodiments, the hip joint A can be fixed during movement. In some embodiments, the thigh mechanism 1 can approximate the femur of the leg. In addition, the lower knee joint B2 can approximate the knee of the leg. In some embodiments, the calf mechanism 5 can approximate the tibia, and the heel or ankle of the person can approximate the heel joint D. In various embodiments, the angle defined between the thigh mechanism 1 and the calf mechanism 5 can be the same as the angle defined between the femur and the tibia.

[0081] Now refer to FIG. 3A to FIG. 3B, a portion of a leg actuator mechanism according to an exemplary embodiment of the present disclosure is provided. In some embodiments, the leg actuator mechanism may include a mounting plate assembly 6, which is configured as a portion of the leg actuator mechanism. In various embodiments, the femoral mounting connector 6 connects the femur 7a (shown in FIG. 4A to FIG. 8 In some embodiments, the mounting plate 6b may define a follower path 2, which is configured to receive a follower connector C1 (eg, Figure 3B In various embodiments, the angle defined between the femur 7a and the tibia 7c (shown in FIG. 4A to FIG. 8 In some embodiments, the position of the foot of the leg actuator mechanism may be based on the position of the follower joint C1 along the second direction within the follower path, and the position of the foot of the leg actuator mechanism may be based on the position of the follower joint C1 along the first direction within the follower path. Figures 1A to 1D The upper follower connection 3 shown may correspond to the connecting rod 6d. In various embodiments, the drive plate 6c may be configured to drive the follower joint C1 (eg, Figure 3B In various embodiments, the drive plate 6c may be activated by a drive mechanism (eg, as discussed below with reference to FIGS. 9-10 ).

[0082] Now refer to 4A to 4D , showing four different leg positions according to an exemplary embodiment of the present disclosure. In various embodiments, 4A to 4D The four positions of the leg actuator mechanism shown correspond to the reference Figures 1A to 1D and Figure 1E to Figure 1H There are four positions discussed. 4A to 4D As shown, the position of the leg actuator mechanisms simulates the movement of the legs during locomotion (eg, walking or running).

[0083] As shown in the figure, the movement between the first position and the fourth position simulates the movement of the legs. Figure 5 ,according to Figure 4A The first position shown in FIG. 1 shows a cross-sectional view of the leg actuator mechanism. In various embodiments, the femur 7a may correspond to Figures 1A to 1D and Figure 1E to Figure 1H The thigh mechanism 1 shown. In some embodiments, the inner femoral rod 7b may correspond to Figures 1A to 1D and Figure 1E to Figure 1H The lower follower connector 4 shown. In some embodiments, the tibia 7c may correspond to Figures 1A to 1D and Figure 1E to Figure 1H The lower leg structure 5 is shown. In various embodiments, the angle defined between the femur 7a and the tibia 7c can be slightly less than 180 degrees.

[0084] Now refer to Figure 6 ,according to Figure 4BThe second position shown shows a cross-sectional view of the leg actuator mechanism. Figure 1B As discussed, as the follower joint C1 travels along the follower path, the thigh mechanism (e.g., femur 7a) and the lower leg mechanism (e.g., tibia 7c) rotate about the hip joint A (as shown in FIG. 3 ). Similarly, as described above with reference to Figure 1F As discussed, as the follower joint C1 travels according to the defined follower path, the thigh mechanism (e.g., femur 7a) and the shank mechanism (e.g., tibia 7c) rotate about the hip joint A (shown in FIG. 3 ). In addition, as the leg moves from the first position to the second position, the angle defined between the femur 7a and the tibia 7c may begin to decrease. In various embodiments, the angle between the femur 7a and the tibia 7c may have a predetermined range of motion. For example, in some embodiments, the range of motion may be from approximately 45 degrees to 180 degrees. In various embodiments, the range of motion may be based on the use case (e.g., the range of motion of the angle defined between the femur 7a and the tibia 7c may be similar to the range of motion of the human femur and tibia). In some embodiments, the angle between the femur 7a and the tibia 7c may exceed 180 degrees (e.g., to simulate a wider range of motion). In this embodiment, the joint A may remain stationary, while the other components may operate in mirrored positions.

[0085] Now refer to Figure 7 ,according to Figure 4C The third position shown shows a cross-sectional view of the leg actuator mechanism. Figure 1C As discussed, as the follower joint C1 travels along the follower path from the second position to the third position, the angle defined between the thigh mechanism (e.g., femur 7a) and the lower leg mechanism (e.g., tibia 7c) can continue to decrease. Similarly, as described above with reference to Figure 1G As discussed, as the follower joint C1 travels from the second position to the third position according to the defined follower path, the angle defined between the thigh mechanism (e.g., femur 7a) and the leg mechanism (e.g., tibia 7c) may continue to decrease. Additionally, the tibia 7c (and subsequently the foot of the leg) may begin to move forward based on movement along the follower joint C1.

[0086] Now refer to Figure 8 , showing that according to Figure 4D A cross-sectional view of the leg actuator mechanism in the fourth position shown. Figure 1D As discussed, as the follower joint C1 continues to travel along the follower path from the third position to the fourth position, the angle defined between the thigh mechanism (e.g., femur 7a) and the lower leg mechanism (e.g., tibia 7c) begins to increase. Similarly, as described above with reference to Figure 1HAs discussed, as the follower joint C1 continues to travel from the third position to the fourth position according to the defined follower path, the angle defined between the thigh mechanism (e.g., femur 7a) and the shank mechanism (e.g., tibia 7c) begins to increase. In various embodiments, the angle defined between the thigh mechanism (e.g., femur 7a) and the shank mechanism (e.g., tibia 7c) may be the same as the angle at the second position. In various embodiments, in the case where the follower joint C1 continues to travel along the follower path in a clockwise direction, the leg actuator mechanism will move from the fourth position back to the first position. In the case where the follower joint C1 moves clockwise around the follower path, the leg actuator can simulate forward movement (e.g., walking or running forward). In the case where the follower joint C1 moves counterclockwise around the follower path, the leg actuator can simulate backward movement (e.g., walking or running backward).

[0087] Now refer to 9A to 10B , a doll according to an exemplary embodiment of the present embodiment is provided. As shown in the figure, the doll includes a driving mechanism 12, and the driving mechanism 12 is configured to start Figure 3B Movement of drive plate 6c is shown. In various embodiments, drive mechanism 12 may be partially or completely internal and / or external.

[0088] exist Fig. 9B In the exemplary embodiment shown, the drive mechanism 12 may have a mounting bracket 12a. In some embodiments, the mounting bracket 12a may be part of the internal and / or external structure of the doll. In some embodiments, the drive mechanism 12 may have one or more drive plug-ins (e.g., internal drive plug-in 12a and / or external drive plug-in 12d) that are configured to receive a driver plug-in (discussed below with reference to FIG. 11). In various embodiments, as shown in FIG. Fig. 9B As shown, the drive plug can be configured to rotate so that the rotational motion from the drive plug can be transmitted to the drive mechanism 12 and then to the drive disk 6c. In various embodiments, the drive mechanism 12 can include one or more connecting rods, which are configured to transfer rotational motion between different items (e.g., 12j).

[0089] As an example, a driver plug-in (not shown) may be attached to the drive plug-in 12d and transfer the rotational motion to the drive mechanism 12. In this example, the rotational motion may be transferred between the drive plug-in 12d and the disk 12c (e.g., via operative coupling). The disk 12c may then be coupled to the arm mechanism 12b (e.g., to move the arm during movement). Additionally, the rotational motion of the drive plug-in 12d may be transferred to the disk 12f. In this case, the disk 12f may be coupled to the connecting rod 12h so that the rotational motion is transferred to the disk 12i, which is operatively coupled to the drive disk 6c (shown in FIG. 3).

In some embodiments, drive mechanism 12 can be configured to activate multiple leg actuator mechanisms simultaneously (e.g., two legs can be offset to accurately simulate running on two legs). In addition, drive mechanism 12 can be used to rotate one or more arm mechanisms, as discussed herein. In some embodiments, the rotational movement of drive plug-in (e.g., 12e and / or 12d) can cause multiple leg actuator mechanisms and arm mechanisms to move. For example, a drive plug-in can provide rotational movement to two legs and two arms (e.g., of a humanoid doll). Various other animals (e.g., animals with legs) can also be simulated using various embodiments discussed herein. In some embodiments, different features (character) (e.g., humanoid dolls or animals) can have follower paths specifically defined based on the features. For example, to simulate larger movements of the legs, the length of the follower path can be longer. In some embodiments, multiple follower paths and / or follower mechanisms can be used to simulate more complex movements (e.g., to simulate animals with legs with multiple joints).

[0091] Now refer to FIG. 11A to FIG. 11B, providing multiple views of a carrying mechanism 10 according to an exemplary embodiment of the present disclosure. In various embodiments, the carrying mechanism 10 may include a drive control device (e.g., a steering wheel and / or a handle bar 10a). In some embodiments, the carrying mechanism 10 may optionally have an impact barrier 10b to protect a doll during operation. In some embodiments, the presence of the impact barrier 10b may be based on the material of the doll (e.g., a doll made of a cushioning material such as polyurethane foam may not need to be protected). In various embodiments, the carrying mechanism 10 may include a doll latch 10c, which is configured to removably attach the doll to the carrying mechanism. In addition, as described in reference Figure 12 to Figure 13 As discussed, the carrying mechanism may include a carrier latch 10d configured to removably attach the doll to the carrying mechanism 10. In some embodiments, the carrying mechanism may be integral with the carrier. Various carrying mechanisms 10 may be used to transfer rotational motion to the drive mechanism 12 discussed above, and FIG. 11A to FIG. 13 The exemplary embodiments are intended to be illustrative only.

[0092] like Fig. 11C As shown, the driver plug-in 10e can be configured to cooperate with a drive plug-in (e.g., drive plug-in 12e) so that the rotation of the driver plug-in 10e can be transmitted to the drive mechanism 12. In various embodiments, the driver plug-in 10e can be in communication with one or more wheels of the carrier mechanism 10 (e.g., the rotational movement of the wheel can be transmitted to the driver plug-in 10e via a pulley or a connecting rod).

[0093] Now refer to Fig.12 and Fig.13 According to an exemplary embodiment, a mobile doll system is provided. Now referring to Fig.12 , the doll 8, the carrying mechanism 10 and the carrier 11 are provided separately from each other.

In addition, the carrier 11 can be attached to the carrying mechanism 10 via the carrier latch 10d discussed above. In some embodiments, the carrier 11 and the carrying mechanism 10 can be an integral unit (e.g., a specially designed carrier including the carrying mechanism). In various embodiments, other types of vehicles 11 can be used. For example, the vehicle can be a recreational vehicle, such as a bicycle, a scooter, a miniature car, a radio-controlled car, and a skateboard, or the like. In various embodiments, the vehicle can be designed specifically for a given doll (e.g., used as a set). Additionally or alternatively, the carrying mechanism 10 can be an accessory to an existing vehicle (e.g., the carrying mechanism can be attached to a bicycle).

[0094] The various embodiments discussed herein allow a doll to simulate movement (e.g., running and / or walking) in a more realistic manner, which provides a more immersive user experience. For example, the embodiments discussed herein allow a doll to "run" with a child riding a vehicle (such as a bicycle or scooter or the like).

[0112] The operation of the aforementioned mechanism 300 and its various components and parts will now be described according to some embodiments and with reference to the various figures described above.

[0113] In some embodiments, such as at least Fig.21 , the wheel WF2 of the wheel and fork assembly 304 can rotate about the shaft WF3 of the wheel and fork assembly 304. In other embodiments, the lower pulley P1 of the pulley assembly 308 can be latched to the wheel WF2 and thereby also rotate about the shaft WF3 as the wheel WF2 rotates. In further embodiments, the lower pulley P1 can transfer the rotational motion to the belt P2. In some embodiments, the belt P2 can transfer the rotational motion to the upper pulley P3. In other embodiments, the upper pulley P3 can then transfer the rotational motion to the miter gear P4 of the pulley assembly.

[0114] Now at least refer to Fig.23, in further embodiments, the miter gear P4 can then transfer the rotational motion to the second center miter gear CM5 of the center mounting assembly 306, which in some embodiments can then transfer the rotational motion to the free-spinning shaft CM2, which is also the center mounting assembly 306. In some embodiments, the free-spinning shaft CM2 can be mechanically latched to the ball bearing CM3, and in some embodiments, the ball bearing CM3 can allow the free-spinning shaft CM2 to rotate freely. It should be understood that according to some embodiments, CM2 can rotate freely independent of the direction of the wheel WF2.

[0115] Now at least refer to Fig.24 The direction of wheel WF2 can be controlled by a handle assembly 302 which can be mechanically latched to a free-spinning axle frame CM1 of a fork and center mounting assembly 306 (further details are shown at least in Fig.18 middle).

[0116] Now at least refer to Fig.26 It should be understood that in some embodiments, the free-spinning shaft CM2 can rotate freely and / or independently of the direction of the wheel WF2, and the free-spinning shaft CM2 can transfer rotational motion to the miter gear CM4, which in some embodiments can transfer rotational motion to the first miter gear B1 of the second set of gear and shaft assembly 310. In this manner, the central mounting assembly 306 can at least transfer energy to the gear and shaft assembly 310. The direction of the first miter gear B1 of the second set can be controlled by the grip assembly 302 at least for the reason that the first miter gear B1 of the second set can be mechanically latched to the free-spinning shaft mount CM1. In other embodiments, the first miter gear B1 of the second set can transfer rotational motion along various parts (B2 to B8) of the second set, such that the first miter gear B1 of the second set transfers rotational motion to the fifth miter gear B8 of the second set, which in some embodiments can transfer rotational motion to the robotic leg actuation mechanism. Additionally, in some embodiments, the miter gear CM4 can transfer rotational motion to the first miter gear A1 of the first group, which can similarly transfer motion along various parts (A2 to A8) of the first group, such that the first miter gear A1 of the first group transfers rotational motion to the fifth miter gear A8. It should be understood that the first miter gear A1 of the first group is not mechanically latched to the fork and free-spinning shaft bracket CM1, and therefore, the direction of A1 is not controlled by the handlebar assembly 302. However, the first miter gear A1 of the first group is mechanically latched to the bicycle 301 via the gear mount F7. In some embodiments, the fifth miter gear A8 can transfer rotational motion to the mechanical leg actuation mechanism via shaft A9 and miter gear A10, such as at least in Fig.25 It is explained in.

[0117] At least through the operations described above in this disclosure, and as Figures 14 to 30I As shown, the front-to-back steering alignment mechanism 300 can allow a user of the bicycle 301 (or any exemplary vehicle) to control a doll (e.g., a horse-shaped doll 400) so that if the user turns the handle assembly 302 in one direction, the front portion 402 of the doll remains aligned with the rear portion 404 of the doll. For example, if the user tilts the handle assembly 302 to the right, the front portion 402 of the doll will tilt to the right, while the rear portion 404 of the doll will tilt to the left, maintaining alignment. Similarly, if the user tilts the handle assembly 302 to the left, the front portion 402 of the doll will tilt to the left, while the rear portion 404 of the doll will tilt to the right, maintaining alignment.
