[0015] This utility model has the following beneficial effects:

[0016] The head mechanism integrates a voice recognition module, ultrasonic ranging sensor, and gesture recognition sensor, enabling the robot to perform voice interaction, environmental perception, and gesture recognition, enriching human-computer interaction methods and enhancing user experience. Driven by multiple servo motors and meticulously designed shoulder and elbow joints, the robot's upper limbs and legs can perform complex and precise movements, simulating human limb movements, suitable for various scenarios such as dance, performance, and service. The chest mechanism adopts a hollow support frame design, centrally housing core components such as the main control board, servo control board, and expansion board, facilitating maintenance and upgrades. This structure also enhances the robot's overall stability. The chest mechanism has reserved expansion board interfaces, allowing for the addition of more functional modules, such as cameras and sensors, to meet the needs of different application scenarios. The leg mechanism employs a design with at least four servo motor servo groups, each servo independently controlled, enabling precise control of complex leg movements and improving the robot's motion coordination and stability. Several connecting shells connect the servo motor servo groups, ensuring the robustness of the leg structure while facilitating servo motor installation and debugging.

[0017] Preferably, the design of the two servo disk groups of the shoulder joint assembly and the shoulder connecting bracket enables multi-degree-of-freedom control of shoulder movement (such as lifting and rotation); the innermost servo disk group is aligned and connected with the groove of the support frame, which enhances structural stability, avoids loosening or falling off due to frequent movements, and ensures the accuracy and durability of shoulder movement.

[0018] Preferably, the elbow joint assembly drives the palm through a servo motor servo disk assembly and utilizes a connecting bracket to achieve flexible bending; this design simplifies the elbow transmission structure, reduces mechanical complexity, and at the same time ensures the independent control capability of the palm (such as gripping objects or making gestures), thereby improving the operational flexibility of the humanoid robot.

[0019] Preferably, the front connecting frame integrates a dot matrix screen (for displaying status or interaction) and an MPS module (possibly a motion processing unit) to enhance human-computer interaction and motion control capabilities; the rear connecting frame is equipped with an LED star ring (visual feedback or decoration) and a switch (emergency stop or mode switching) to optimize the safety and visual management of equipment operation.

[0020] Preferably, the leg mechanism is connected to the chest support frame through the hip mechanism to ensure balanced force on both legs and improve stability when walking or jumping; the symmetrical design of the servo rudder assembly and connecting shell also facilitates modular assembly and maintenance, reducing the failure rate.

[0021] Preferably, the battery is placed inside the connecting shell at the bottom of the leg, which optimizes the center of gravity by utilizing gravity distribution, making the robot more stable when standing. At the same time, since there are many motors distributed in the leg, the battery can be close to the leg motors to shorten the power supply line, reduce energy loss, and extend the battery life.

[0022] Preferably, the observation port on the connecting housing allows users to visually check the internal battery status (such as power indicator lights or physical interfaces), facilitating quick replacement or maintenance without disassembling the entire structure, thus improving user experience and maintenance efficiency.

[0023] Preferably, the cable outlet facilitates wiring and supports signal and power transmission; the heat dissipation gap helps to accelerate heat dissipation, prevent the leg motor or battery from overheating, and extend the hardware life.

[0024] Preferably, a layered architecture of Arduino main control board and servo control board is adopted. The Arduino ecosystem is relatively mature, which simplifies the system development difficulty. At the same time, the servo control board centrally manages the servo signals, reducing the load on the main control board and improving the response speed and reliability.

[0025] Preferably, the servo drives the dual servo discs, reducing the number of servos and saving leg space; the LX-824HV servo features high torque and low power consumption, making it suitable for the complex motion requirements of humanoid robots; the three-interface serial wiring can reduce the number of cables, simplify wiring, reduce the risk of electromagnetic interference, and improve system reliability.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] like Figure 1As shown, a humanoid robot driven by 16 servo motors includes a head mechanism 103, an upper limb mechanism, a chest mechanism, and a leg mechanism. The head mechanism 103 is located on the upper side of the chest mechanism and includes a voice recognition module, an ultrasonic ranging sensor, and a gesture recognition sensor. The chest mechanism includes a support frame 100, the interior of which is hollow to form a receiving cavity. The receiving cavity houses a main control board, a servo motor control board, and an expansion board.

[0038] The upper limb mechanism is symmetrically arranged on the left and right sides of the chest mechanism. The upper limb mechanism includes, in sequence, a shoulder joint assembly, a robotic arm external connecting baffle 54, an elbow joint assembly, and a hand 55. The shoulder joint assembly is assembled and connected to the support frame 100 to realize the connection between the upper limb mechanism and the chest mechanism.

[0039] Specifically, the shoulder joint assembly includes a shoulder joint servo servo disk assembly 50, which includes at least one servo and at least two servo disks arranged opposite each other. The servo drives the two servo disks in the same group. One servo disk is aligned and connected with a groove provided on the support frame 100, and the other servo disk faces outward to facilitate connection with the elbow joint assembly.

[0040] In operation, the shoulder connecting bracket 53 rotates around the axis of the servo disk of the shoulder joint servo motor assembly 50. The rotational motion of the shoulder connecting bracket 53 enables the twisting of the robot's shoulder.

[0041] like Figure 3As shown, the shoulder joint assembly includes at least two servo servo disk assemblies (elbow joint servo disk assembly 51 and hand joint servo disk assembly 52) and a shoulder connecting bracket 53 between the servo disk assemblies. The innermost servo disk assembly is aligned with a groove on the support frame 100. The shoulder connecting bracket 53 is U-shaped and connected to the elbow joint servo disk assembly 51. The elbow joint servo disk assembly 51 includes at least one servo and at least two opposing servo disks. The two sides of the shoulder connecting bracket 53 are respectively connected to the main and auxiliary servo disks of the elbow joint servo disk assembly 51. Specifically, two opposing circular frames are provided on both sides of the shoulder connecting bracket 53. The circular frames are cylindrical servo disk grooves corresponding to the servo disks. The elbow joint servo disk assembly 51 is connected to the outer connecting baffle 54 of the robotic arm. Specifically, the servo of the elbow joint servo disk assembly 51 is located on the robotic arm. Inside the outer connecting baffle 54 of the arm, the servo disk of the elbow joint servo disk assembly 51 is mounted on the disc frame of the shoulder connecting bracket 53; the outer connecting baffle 54 of the robotic arm is cuboid in shape and has an internal space for accommodating; the hand joint servo disk assembly 52 is also connected to the outer connecting baffle 54 of the robotic arm, and the elbow joint servo disk assembly 51 and the hand joint servo disk assembly 52 are respectively installed on both sides of the outer connecting baffle 54 of the robotic arm; the hand joint servo disk assembly 52 includes at least one servo and at least two servo disks arranged opposite each other, and the palm 55 is connected to the main and auxiliary servo disks of the hand joint servo disk assembly 52.

[0042] In operation, the servo motors of the elbow joint servo motor assembly 51 connected to the shoulder connecting bracket 53 drive the elbow joint servo motor assembly 51 to rotate around the axis of the servo motor assembly 51, thereby enabling the robot's arm to bend. The servo motors of the hand joint servo motor assembly 52 drive the hand 55 to rotate around the axis of the servo motor assembly 52, thereby enabling the robot to bend the hand.

[0043] The chest mechanism also includes a front chest connecting frame 101 and a back connecting frame 102 respectively provided on the front and rear sides of the support frame 100; a dot matrix screen and an MPS module are arranged in sequence on the front chest connecting frame 101, and an LED star ring and a switch are arranged in sequence on the back connecting frame 102.

[0044] The lower limb mechanism includes a hip mechanism and a leg mechanism in sequence.

[0045] The leg mechanism is connected to the support frame 100 of the chest mechanism via the hip mechanism; the hip mechanism is a symmetrical structure, including at least two servo rudder disk assemblies and at least two connecting shells symmetrically arranged.

[0046] Specifically, the hip mechanism includes a hip servo 1, a front hip servo disc 2, a rear hip servo disc 3, and a hip connecting housing 4, all mounted on the lower side of the chest mechanism. The hip connecting housing 4 is cubic in shape, with two parallel and opposing disc frames extending upwards. The two disc frames are provided with opposing servo disc grooves, which are used to connect the front hip servo disc 2 and the rear hip servo disc 3, respectively. A fourth leg servo 5 is installed inside the hip connecting housing 4, and a corresponding servo disc is installed on the outside of the fourth leg servo 5.

[0047] In operation, the hip servo motor 1 drives the front hip servo disk 2 and the rear hip servo disk 3, and the hip connecting shell 4 swings left and right around the axis of the front hip servo disk 2 and the rear hip servo disk 3, so that the robot's leg mechanism can lift its legs to the left and right sides from 0° to 90°.

[0048] The leg mechanisms are arranged symmetrically in pairs on the lower side of the chest mechanism. Each leg mechanism includes at least four servo spools and several connecting housings or connecting frames. The uppermost servo spool of the leg mechanism is connected to the chest mechanism; the lowermost servo spool of the leg mechanism is connected to the connecting housing.

[0049] Specifically, the leg mechanism includes a fourth leg servo disc assembly, an upper leg connecting shell 8, a third leg servo disc assembly, a middle leg connecting shell 12, a second leg servo disc assembly, an ankle connecting frame 16, a first leg servo disc assembly, and a foot connecting shell 20.

[0050] Specifically, the leg-mounted fourth servo assembly includes a leg-mounted fourth servo 5, a leg-mounted fourth left servo 6, and a leg-mounted fourth right servo 7 mounted on the leg-mounted fourth servo 5. The upper leg-mounted connecting housing 8 is cubic in shape, with two parallel, opposing disc frames extending upwards from the upper leg-mounted connecting housing 8. The two disc frames have opposing servo disc grooves, used to connect the leg-mounted fourth left servo 6 and the leg-mounted fourth right servo 7, respectively. A leg-mounted third servo 9 is located inside the upper leg-mounted connecting housing 8. It is noteworthy that the axes of the leg-mounted fourth left servo 6 and leg-mounted fourth right servo 7 are perpendicular to the axes of the hip-mounted front servo 2 and hip-mounted rear servo 3, ensuring that the leg mechanism has degrees of freedom in two vertical directions, which helps improve the efficiency of mechanical movement.

[0051] In operation, the fourth servo motor 5 of the leg drives the fourth left servo disk 6 and the fourth right servo disk 7 of the leg. The upper connecting shell 8 of the leg moves back and forth and bends around the axis of the fourth left servo disk 6 and the fourth right servo disk 7 of the leg, so that the robot's leg mechanism can realize the action of swinging and lifting the thigh from 0° to 270°.

[0052] Specifically, the third leg servo assembly includes a third leg servo 9, a third left leg servo 10 mounted on the third leg servo 9, and a third right leg servo 11. The middle leg connecting housing 12 is cubic in shape, with two parallel and opposing disc frames extending upward from the middle leg connecting housing 12. The two disc frames are provided with opposing servo disc grooves, which are used to connect the third left leg servo 10 and the third right leg servo 11, respectively. A second leg servo 13 is disposed inside the middle leg connecting housing 12.

[0053] In operation, the third leg servo motor 9 drives the third left leg servo disk 10 and the third right leg servo disk 11. The middle connecting shell 12 of the leg moves back and forth and bends around the axis of the third left leg servo disk 10 and the third right leg servo disk 11, enabling the robot's leg mechanism to bend the knee, squat, raise the lower leg, and swing the knee back and forth from 0° to 270°.

[0054] Specifically, the leg-mounted second servo rotor assembly includes a leg-mounted second servo 13, a leg-mounted second left servo rotor 14, and a leg-mounted second right servo rotor 15 mounted on the leg-mounted second servo 13. The ankle connector 16 includes a connecting plate and several disc frames. The connecting plate extends two parallel and opposing disc frames to the upper and lower sides respectively. Both the upper and lower disc frames are provided with opposing servo rotor grooves, but the planes of the upper and lower disc frames are perpendicular to each other. The two upper disc frames are used to connect the leg-mounted second left servo rotor 14 and the leg-mounted second right servo rotor 15 respectively. The two lower disc frames are used to connect the leg-mounted first front servo rotor 18 and the leg-mounted first rear servo rotor 19 respectively. The foot-mounted connecting housing 20 is provided with a leg-mounted first servo 17.

[0055] In operation, the second leg servo motor 13 drives the second left leg servo disk 14 and the second right leg servo disk 15. The ankle connecting frame 16 moves back and forth and bends around the axis of the second left leg servo disk 14 and the second right leg servo disk 15, enabling the robot's leg mechanism and ankle to bend and swing back and forth from 0° to 270°.

[0056] Specifically, the first leg servo assembly includes a first leg servo 17 and a first front leg servo 18 and a first rear leg servo 19 mounted on the first leg servo 17. The foot connecting shell 20 is cubic in shape, larger in volume than the upper leg connecting shell 8 and the middle leg connecting shell 12, and also heavier for the same material. Notably, the axes of the first front leg servo 18 and the first rear leg servo 19 are perpendicular to the axes of the second left leg servo 14 and the second right leg servo 15, to prevent the robot's center of gravity from having only one degree of adjustment freedom in the lower part of the leg mechanism, thus helping to maintain the overall balance of the robot's center of gravity.

[0057] In operation, the first leg servo motor 17 drives the first front leg servo disk 18 and the first rear leg servo disk 19, and the foot connecting shell 20 moves back and forth and bends around the axis of the first front leg servo disk 18 and the first rear leg servo disk 19, so that the robot's foot connecting shell 20 can perform horizontal rotation within the range of 0° to 180°.

[0058] The robot's lower limb design in this embodiment mainly uses a servo motor servo disk assembly and a connecting shell. Holes adapted to the servo disk are reserved on the connecting shell to facilitate the fastening of screws for fixation, making the overall structure flexible and more compact.

[0059] The motion principle of the robot's lower limb design in this embodiment is as follows: the corresponding part of the servo motor servo disk group drives the corresponding part of the connecting shell or connecting frame to perform a preset motion, so that the motion remains uniform and the adjustment process is more convenient.

[0060] In the robot's lower limb design of this embodiment, the fourth servo motor 5 of the leg is designed to be placed horizontally, while the third servo motor 9 and the second servo motor 13 of the leg are designed to be placed vertically. This reasonably controls the length of the robot's leg mechanism and ensures the aesthetics of the robot design.

[0061] In the robot's lower limb design of this embodiment, the first servo motor 17 of the leg is designed to be placed horizontally, which allows the servo motor to be more stably fixed to the foot connecting shell 20.

[0062] In the robot's lower limb design of this embodiment, all connecting shells adopt a semi-enclosed structure. The connecting shells reserve the necessary cable outlets and also leave gaps on some mating surfaces to improve the heat dissipation of the servo motors during operation.

[0063] In the robot's lower limb design of this embodiment, all connecting shells have large clearances inside, providing sufficient space for the corresponding servo motor cables to be fixed, while ensuring the safety of robot movement and the aesthetics of the design.

[0064] In this embodiment of the robot's lower limb design, the foot-connecting shell 20 is designed as a slightly larger cuboid. The space inside the foot-connecting shell 20 is used to install the 12V battery that drives the servo motor, and an observation port is provided in the foot-connecting shell 20. Fixing the battery inside the foot-connecting shell 20 lowers the robot's center of gravity to the foot position, which helps the robot to complete a series of actions smoothly. The reserved observation port facilitates real-time monitoring of the battery level and also plays a certain role in heat dissipation.

[0065] In the robot's lower limb design of this embodiment, the foot connecting shell 20 is designed with a large length redundancy, which provides sufficient space for fixing the battery extension wires to prevent the robot from being tripped by the wires, causing movement interruption or even damage to the servo motors, thus ensuring the robot's rationality and overall aesthetics.

[0066] In this embodiment, the main control board uses an Arduino development board; the main control board communicates with the servo servo assembly via a servo control board. Specifically, as shown... Figure 6 As shown, the Arduino development board controls a dot matrix screen, speaker module, LED aperture, and laser rangefinder sensor via an expansion board. The expansion board also connects to a servo control board and an ICC expansion board. The servo control board controls eight servo spool groups, each group consisting of at least one servo and at least two oppositely arranged spools. Each servo drives the two spools in the same group. All servos are LX-824HV type serial bus servos, connected in series with three interfaces. The ICC expansion board controls an OLED display, a voice recognition sensor, and a gesture recognition sensor.

[0067] In this embodiment, the servos of the shoulder joint servo disk group 50, elbow joint servo disk group 51, hand joint servo disk group 52, hip servo 1, and leg mechanism are all LX-824HV model serial bus servos. Compared with the traditional 7.4V LX-824 servo, the robot's endurance is significantly improved. The three-interface serial connection reduces messy wiring, making the wiring of the entire system more beautiful and concise, which helps to realize the miniaturization of the robot.

[0068] The mechanical transmission mechanism designed above enables multi-angle rotation of the robot's upper limbs, thereby completing various preset movements and meeting the needs of various robot application scenarios. Simultaneously, the use of servo motors and connecting structural components for transmission results in a compact upper limb structure, contributing to the miniaturization of the robot.

[0069] The above embodiments are merely one of the implementation methods for achieving the technical solution of this utility model. The scope of protection claimed by this utility model is not limited to this embodiment, but also includes any variations, substitutions, and other implementation methods that are easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model.
