[0009] Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals. The robot 200 according to the embodiment is a small pet robot that mimics an animal and uses a battery capable of contactless power supply to swing its head (or a corresponding part). As an example, as shown in Figure 1, the robot 200 is equipped with an exterior 201 having decorative parts 202 that mimic eyes and fur 203. As shown in Figure 2, the robot 200 is equipped with a housing 207. The housing 207 is covered by the exterior 201 and is housed inside the exterior 201. The housing 207 is an electronic device comprising a head 204, a connecting part 205, and a body part (case) 206. The connecting part 205 connects the head 204, which is a movable part, and the body part 206, which is the main body part.

[0010] In the following description, assuming that the robot 200 is normally placed on a horizontal floor, the direction of the portion corresponding to the face of the robot 200 (the portion on the opposite side of the body portion 206 of the head portion 204) is defined as the front, and the direction of the portion corresponding to the tail (the portion on the opposite side of the head portion 204 of the body portion 206) is defined as the rear. Also, when the robot 200 is placed on a horizontal floor surface, the direction of the portion in contact with the floor surface is defined as the bottom, and the opposite direction is defined as the top. And the direction that is perpendicular to the straight line extending in the front-rear direction of the robot 200 and also perpendicular to the straight line extending in the up-down direction is defined as the left-right direction.

[0011] The exterior 201 is an example of an exterior member, and has a bag-like shape that is long in the front-rear direction and can accommodate the housing 207 inside. The exterior 201 is formed in a slender shape extending from the head portion 204 to the body portion 206, and integrally covers the body portion 206 and the head portion 204. By having the exterior 201 with such a shape, the robot 200 is formed in a belly-up shape. The surface fabric of the exterior 201 is formed of an artificial pile fabric that imitates the hair 203 of a small animal in order to simulate the texture of the skin of a small animal. The lining of the exterior 201 is formed of a flexible material such as leather, resin, rubber, etc. Since it is formed of a flexible material, the exterior 201 follows the movement of the housing 207. Specifically, the exterior 201 follows the rotation of the head portion 204, which is a movable part with respect to the body portion 206.

[0012] As shown in FIG. 2, the body portion 206, which is the main body part, extends in the front-rear direction. The body portion 206 contacts the placement surface such as the floor or table on which the robot 200 is placed through the exterior 201. The body portion 206 includes a torsion motor 221 at its front end. The head portion 204 is connected to the front end of the body portion 206 via a connecting portion 205. The connecting portion 205 includes an up-down motor 222. The head portion 204 is connected to the body portion 206 so as to be rotatable about the left-right direction and the front-rear direction of the robot 200.

[0013] The connecting section 205 connects the body section 206 and the head section 204 so as to be rotatable around the motor rotation shaft 2615 (with a fixing member 291 screwed into it) shown in Figure 4, which is the first rotation shaft that extends in the front-rear direction of the body section 206 through the connecting section 205. The twist motor 221 is a servo motor for rotating the head section 204 clockwise (right-hand rotation) or counterclockwise (left-hand rotation) around the first rotation shaft relative to the body section 206. The connecting section 205 also connects the body section 206 and the head section 204 so as to be rotatable around the second rotation shaft that extends in the left-right direction of the body section 206 through the connecting section 205. The up-down motor 222 is a servo motor for rotating the head section 204 upward (forward rotation) or downward (reverse rotation) around the second rotation shaft. The twist motor 221 and the up / down motor 222 are components of the motor unit that operates the head 204.

[0014] As shown in Figures 3 and 4, the torso 206 is a cylindrical case made of, for example, ABS (Acrylonitrile Butadiene Styrene) resin, and has a first case 250 that forms the back side of the torso 206 of the robot 200, and a second case 280 that forms the ventral side of the torso 206. The torso 206 houses the twist motor 221, secondary battery 264, battery holder 265, coil holder 266, power receiving coil 268, etc.

[0015] As shown in FIGS. 4, 5, and 6, the first case 250 includes a twisting motor 221 that provides power to the head 204, an operation unit fixing part 262 that fixes the twisting motor 21 and the connecting part 205 to the body part 206, a board mounting part 263 on which a main board 275 and the like are mounted, a secondary battery 264 that supplies power to the robot 200, a battery holder 265 that holds the secondary battery 264, a main board 275 that controls the robot 200, and a PSoC board 276. The first case 250 constitutes the upper half of the outer shell of the body part 206. As shown in FIG. 5, the first case 250 has an operation unit fixing part through hole 251 formed in the front, through which the motor rotation shafts 2615 of the twisting motor 221 and the up-and-down motor 222 are inserted into the connecting part 205. Also, the operation unit fixing part through hole 251 has an opening with a diameter considerably larger than the motor rotation shaft 2615 so that the operation unit fixing part 262 housing the twisting motor 221 can be removed while being slid forward. In the first case 250, the screw holes 253 are used together with the fitting part 254 to integrate the first case 250 and the second case 280. The screw hole 255 is used to fix the operation unit fixing part 262 to the inside 252 of the first case 250. The screw hole 256 is used to fix the board mounting part 263 to the inside 252 of the first case 250.

[0016] The twist motor 221, together with the head 204, the connecting part 205, the up / down motor 222 within the connecting part, and the operating unit fixing part 262 (described later), constitutes the operating unit 208. The operating unit 208 shown in Figure 7 is a component that enables the operation of the robot 200. The operating unit 208 is a consumable part and is replaced with a new operating unit 208 after a certain period of use. As shown in Figure 4, the motor rotation shaft 2615 of the twist motor 221 protrudes from the main body of the motor 221 and transmits rotation to the gear inside the connecting part 205 to operate the head 204. The connecting part 205 and the twist motor 221 are rotatably connected via the motor rotation shaft 2615. The twist motor 221 is fixed to the operating unit fixing part (motor fixing part) 262 using three screw holes 2617 formed on the front panel of the twist motor 221. Power is supplied from a secondary battery 264 via a connector (not shown) located at the rear of the twist motor 221. The operating unit fixing section 262 shown in Figures 8(a) and (b) fixes the operating unit 208 to the upper front of the first case 250 of the body section 206 with fixing members 290 such as screws. The upper surface of the twist motor 221 is brought into contact with the lower surface of the base section 2621, the circular protrusion of the twist motor 221 is fitted into the motor protrusion insertion hole 2624, the front panel of the twist motor 221 is brought into contact with the fixing section 2622, and the right side of the twist motor 221 is brought into contact with the side wall 2623, and the fixing members 290 such as screws are tightened into the three holes 2626 and screw holes 2617, thereby fixing the operating unit 208 (and its twist motor 221) to the operating unit fixing section 262 (see Figure 4). Furthermore, the operating unit fixing portion 262 is positioned by bringing the contact portion 2627 formed on the upper part of the base portion 2621 into contact with the base portion 2631 of the substrate mounting portion 263 (described later), and inserting the fixing projection 2628 through the fixing hole 2639 of the substrate mounting portion 263 (described later). The operating unit fixing portion 262 is fixed to the first case 250 and the substrate mounting portion 263 by using fixing members 290 such as screws in the two screw holes 2625 and screw hole 255.As shown in Figure 9, the two screw holes 2625 and 255 (which may include the fixing member 290) are the operating unit mounting locations (motor fixing part mounting locations) F, and the operating unit mounting locations are located within a space where a tool such as a screwdriver can be operated (for attaching and removing the fixing member 290) to remove the operating unit 208 (specifically the twist motor 221) from the first case 250, and are not covered by other parts (excluding the secondary battery 264 and battery holder 265) located inside the first case 250 (they are exposed in a state where a tool such as a screwdriver for attaching and removing the fixing member 290 can be operated inside the first case 250). Note that a position where a tool can be operated means a position where there is enough space in the front, back, left, and right directions to move the screw to the screw hole, and a height sufficient to install and tighten the screw with, for example, an electric screwdriver suspended above in the upward direction. As shown in Figures 4, 5, and 10(a) and (b), the main board 275 is mounted on the rear wall 2632 of the board mounting section 2633 using two board mounting bases 2637, and the PSoC board 276 is mounted on the left wall 2633 using two board mounting bases 2637. The board mounting section 263 is attached to the first case 250 using three screw holes 2638 provided in the base 2631. Battery holder fixing protrusions 2635 and screw holes 2636 are formed at the lower ends of the rear wall 2632 and the right wall 2634 of the board mounting section 2633. The battery holder fixing protrusions 2635 and screw holes 2636 are formed at a height that allows the operating unit fixing section 262 housing the twist motor 221 to be positioned in a location surrounded by the rear wall 2632, left wall 2633, and right wall 2634 of the board mounting section 2633. This type of substrate mounting section 263 allows for a compact arrangement of the torsion motor 221, secondary battery 264, main board 275, PSoC board 276, etc., while also ensuring the strength of the substrate mounting section 263.

[0017] The secondary battery 264 that supplies power to the robot 200 is a battery that can be charged by contactless charging. As shown in Figure 5, shock-absorbing material 270 is attached to the secondary battery 264 to protect the area where the protective circuit board inside the battery is located. The battery holder 265 houses the secondary battery 264 with its lower main surface 2651 and peripheral walls 2653, 2654, and 2655, and protects the secondary battery from vibration, shock, etc., together with the shock-absorbing material 270. The upper main surface 2652 of the battery holder 265 is fixed to the lower end of the circuit board mounting part 263 with fixing members 290 such as two screws. Of the peripheral walls 2653, 2654, and 2655 that are erected downward from the main surface 2651, shock-absorbing material (for preventing foreign matter from entering) 270 is provided between the secondary battery 264 and the rear peripheral wall 2654.

[0018] As shown in Figures 11 and 12, the second case 280 includes a coil holder 266 to which a power receiving coil is attached, a power receiving board 267 that transmits the power received by the power receiving coil 268 to the robot 200, a power receiving coil 268 that is wirelessly connected to a power transmitting coil of a charging device (not shown), and a coil tape 269 that protects the power receiving coil 268. The second case 280 constitutes the lower half of the outer shell of the body portion 206. A rectangular opening 282 is formed in the bottom 281 of the second case 280, and as shown in Figure 4, the power receiving coil 268 is positioned inside the opening 282 along the outer surface of the second case 280. A coil holder retainer 283 is formed at the lower rear of the inside of the second case 280, as shown in Figures 4, 11, and 12, and it comes into contact with the protruding portion 2667 of the coil holder 266 when a strong upward force is applied to the coil holder 266. The coil holder retainer 283 has a horizontal portion 2831 that is horizontal to the main surface of the coil holder 266, and a vertical portion 2832 that is vertical and serves as a reinforcing rib for the horizontal portion 2831. The coil holder 266 is fixed to the opening 282 by tightening fixing members 290 such as screws into the four screw holes 287 and the four screw holes 26681 of the coil holder 266. A connecting portion 205 is positioned at the front of the body 284 with a small gap between them. The upper end of the second case 280 has one screw hole 286 on each side. The first case 250 and the second case 280 are fixed to each other and integrated by inserting fixing members 290 such as screws from the screw holes 286 into the screw holes 253 of the first case 250 and tightening them.

[0019] As shown in Figures 4, 11, 12, 13, and 14, a power receiving board 267 is mounted on the upper main surface 2661 of the coil holder 266 with a gap, and a power receiving coil 268, which is attached to the ferrite 271 (bottom surface), is attached to the lower main surface 2662 with double-sided tape 272. The coil holder 266 has vertical risers 2663, 2664, 2664, and 2665 formed on the main surface 2661. The power receiving board 267 is mounted on the coil holder 266 using a fixing member 290 such as a single screw, with the circuit components facing the main surface 2661, on the mounting projection 26611, the mounting base screw hole 26612, etc., and is attached so that its front end is sandwiched between 2666. In this way, the coil holder 266 is mounted so that the power receiving board 267 is housed inside the coil holder 266. The coil holder 266 has a protruding portion 2667 that may come into contact with the coil holder retainer 283 of the second case 280. The protruding portion 2667 includes a flat portion 26671 that comes into contact with the horizontal portion 2831 to suppress deformation of the coil holder 266 when a load is applied, such as when the receiving coil 268 or the coil holder 266 is pushed upward, and a vertical wall 26672 which is a rib that reinforces the flat portion 26671. In normal operation, the flat portion 26671 faces the horizontal portion 2831 with a gap between them and does not come into contact. The coil holder 266 is fitted into the opening 282 of the second case 280 with a small wall 2669. An impact-absorbing material 270 is attached to the mounting portion 26683 of the coil holder 266. As a result, the coil holder 266 is positioned below the secondary battery 264, with shock-absorbing material 270 on either side of its left and right ends, and supports the secondary battery 264 via the shock-absorbing material 270. Furthermore, the coil holder 266 is surrounded on all four sides of a rectangular flat plate and reinforced by reinforcing ribs 26613, so it has high strength even while having an internal cavity to house the power receiving board 267. As shown in Figures 4, 5, and 13, the coil tape 269 is positioned to cover the power receiving coil 268 and close the opening 282. The ends 2692, 2693, 2694, and 2695 of the coil tape 269 are bent and sandwiched between the end of the opening 282 and the coil holder 266 for fixation.

[0020] Furthermore, the robot 200 is equipped with various sensors, a control unit, a memory unit, etc., which are known configurations as described in, for example, Japanese Patent Publication No. 2024-104908, but a detailed explanation is omitted.

[0021] Next, the positional relationships of the components arranged inside the fuselage section 206 will be explained. As shown in Figure 4, in the fuselage section 206, the first case 250 is mounted in the following order from top to bottom: circuit board mounting section 263, operating unit fixing section 262, twist motor 221, battery holder 265, and secondary battery 264. In the second case 280, the power receiving circuit board 267, coil holder 266, power receiving coil 268, and coil tape 269 are mounted in the following order from top to bottom. More specifically, the secondary battery 264 is positioned closest to the opening 282 among the components located inside the first case 250, and the shock absorber 270 attached to the coil holder 266 is positioned furthest from the opening 282 among the components located inside the second case 280. Since the secondary battery 264 is supported by the shock absorber 270 attached to the coil holder 266, when the first case 250 and the second case 280 are disassembled, the secondary battery 264 is positioned in the first case 250 for easy replacement. Therefore, the secondary battery 264 can be removed as soon as the body section 206 is inverted and the second case 280 is removed. In addition, the secondary battery 264 is protected from above and to the left by the battery holder 265, from the front by the second case 280, and from the remaining directions by the shock absorber 270, thereby enhancing the safety of the robot 200. Furthermore, the coil holder 266 is fixed to the periphery of the opening 282 of the second case 280 by inserting the insertion part 288 through two insertion holes 26682 into the second case 280, thereby suppressing movement of the coil holder 266 in the front-back and left-right directions, and by fixing it to the periphery of the opening 282 with the fixing member 290 using four screw holes 26681,287, thereby suppressing movement in the up-down and front-back and left-right directions, thereby increasing the integration between the second case 280 and the coil holder 266 and increasing the strength of the second case 280. In addition, the torsion motor 221 and the operating unit fixing part 262 are positioned on the opposite side of the power receiving coil 268 (the back side of the robot 200) in an overlapping position, so that the power receiving coil 268 and the torsion motor 221 can be compactly arranged when power is received from the ventral side of the robot 200.Furthermore, the operating unit fixing part 262 and the twist motor 221 are positioned on the opposite side (the back side of the robot 200) from the power receiving coil 268 and the secondary battery 264, overlapping each other vertically, and there is a gap between the twist motor 221 and the battery holder 265 (or between the twist motor 221 and the secondary battery 264). This allows the power receiving coil 268, the secondary battery 264, and the twist motor 221 to be compactly arranged within the body part 206, and prevents interference between components even if there is play when fixing the twist motor 221 or dimensional tolerances of the twist motor 221 itself.

[0022] The above describes the configuration of the robot 200 according to this embodiment. Next, the method for replacing the secondary battery 264 and the operating unit 208 of the robot 200 will be described. First, the replacement of the secondary battery 264 will be described. Open the zipper (not shown) on the exterior 201 of the robot 200 and remove the housing 207. Next, invert the housing 207 upside down and remove the second case 280 from the housing 207. As shown in Figure 15, with the second case 280 removed, the housing 207 has the secondary battery 264 positioned so that it can be easily removed from the first case 250, and the user can replace the depleted (or faulty) secondary battery 264 with a new secondary battery 264. After that, attach the second case 280, return the housing 207 to the exterior 201, and close the zipper to easily complete the battery replacement.

[0023] Next, we will explain how to replace the operating unit 208. After removing the secondary battery 264 as described above from the state shown in Figure 15, remove the battery holder 265. As shown in Figure 9, by removing the battery holder 265, which was obstructing the attachment and detachment of the fixing member 290 attached to the screw hole 2625 (it was covering the motor fixing part mounting location F inside the first case 250), the user can now use a screwdriver or other tool on the screw hole 2625 of the operating unit fixing part 262 shown in Figure 8. Remove the fixing member 290 that was attached to the screw hole 2625 and pull out the operating unit fixing part 262 housing the twist motor 221 forward (Figure 5). Replace the pulled-out operating unit 208 with a new operating unit 208. The operating unit fixing part 262 of the new operating unit 208 is attached to the first case 250, and the battery holder 265 is attached to the rear wall 2632, left wall 2633, and right wall 2634 of the circuit board mounting part 263 that are closer to the second case 280. Then, the secondary battery 264 is attached to the battery holder 265, the second case 280 is attached, the housing 207 is returned to the outer casing 201 and the fastener is closed, making it easy to complete the replacement of the operating unit 208.

[0024] As described above, the robot 200 according to this embodiment includes a head 204, an operating unit fixing part 262 for fixing a twist motor 221 and an operating unit 208 that operate the head 204, a body part 206 that houses at least a part of the twist motor 221 and the operating unit fixing part 262, and a connecting part 205 that rotatably connects the head 204 to the body part 206. The body part 206 has a first case 250 to which the operating unit fixing part 262 is attached, and a second case 280 that fits into the first case 250. The operating unit 208, which includes the head 204, the connecting part 205, the operating unit fixing part 262, and the twist motor 221, is such that the head 204, the connecting part 205, the operating unit fixing part 262, and the twist motor 221 are fixedly or rotatably connected to each other. The operating unit fixing part 262 is fixed to the first case 250, and with the second case 280 removed, the operating unit mounting location F, where the operating unit fixing part 262 is fixed to the first case 250, is positioned so that a tool for removing the operating unit 208, including the twist motor 221, from the first case 250 can be attached and removed. Therefore, after removing the outer casing 201, the second case 280, the secondary battery 264 and battery holder 265 of the robot 200, the operating unit 208 can be easily removed from and attached to the first case 250, and the operating unit 208 (motor) can be easily replaced. The first case 250 has a motor fixing part through hole 251 that allows the operating unit fixing part 262, which houses the twist motor 221, to move in the front-rear direction of the body part 206. Therefore, by removing the second case 280, the secondary battery 264 and battery holder 265, and the fixing member 290 of the screw hole 2625, the user can easily remove the operating unit fixing part 262, which houses the twist motor 221 connected to the head 204 and connecting part 205, from the first case 250 by sliding it forward (while slightly lifting it) through the operating unit fixing part through hole 251, resulting in high maintainability.Furthermore, the control boards for the twist motor 221 and the up / down motor 222 are positioned so as not to interfere with the replacement of the operating unit 208 in the torso 206, allowing for easy replacement of the operating unit 208. In addition, the second case 280 can be removed from the housing 207 with the receiving coil 268, receiving board 267, coil holder 266, etc., which are located below the secondary battery 264, attached to it. Since the secondary battery 264 is located at the very bottom of the first case 250, the secondary battery 264 can be easily replaced by inverting the housing 207 and removing the second case 280, resulting in high maintainability. Thus, the robot 200 of this embodiment allows for easy replacement of consumable parts such as the operating unit 208 (twist motor 221, up / down motor 222) and the secondary battery 264.

Furthermore, although the power of the robot 200 was supplied by the secondary battery 264, it may also be supplied by a dry cell battery, a solar cell, or the like. Also, although the secondary battery 264 was charged by contactless charging, it may also be charged by wired charging.

[0026] In the above embodiment, the body portion 206 was configured to have a first case 250 and a second case 280. However, for example, the body portion may be composed of a single case with a removable bottom portion 281, or one case may have an openable and closable door so that secondary batteries, operating units, etc., can be easily replaced. It may also have a configuration with three or more cases. Furthermore, the first case 250 and the second case 280 may be in opposite configurations, or the second case may be attached to the first case in a way that allows it to be opened and closed with a hinge or the like.

[0027] Furthermore, in the above embodiment, the exterior 201 had hair 203, but instead of hair, it may be feathers, or something that imitates the skin of a reptile, etc.

[0028] In the above embodiment, the head 204 (or a part equivalent thereto) which resembles a small animal is configured to move, but the tail (or a part equivalent thereto) may move instead of the head, or both the head and tail may move. Alternatively, the arms, legs, fingers, eyelids, mouth, etc. may move instead of the head, or the arms, shafts, etc., of a non-animal-like machine may move.

[0029] In the above embodiment, the operating unit fixing part 262 was configured to fix the surface on which the motor rotation shaft 2615 of the twist motor 221 protrudes, covering the entire top surface and half of the left side surface. However, it may also be configured to cover the right side surface, or to cover the entire left side surface. It is preferable that the fixing part fixes the surface on which the motor shaft protrudes, but it may also be configured to fix, for example, the bottom surface of the motor unit. Furthermore, the number of motors constituting the motor section may be one or three or more. The motor section was configured with one motor rotation shaft 2615 protruding, but it may have two protruding shafts, or three or more, and the number of motors constituting the motor section may be the same or different. The direction in which the head 204 is operated may be only in the up and down direction, only around the motor rotation shaft 2615, only in other directions, or in multiple directions combining these. Furthermore, although the motor fixing portion passage hole was provided in the first case 250, it may also be provided in the second case 280, or in both the first case 250 and the second case 280.

[0030] Although preferred embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and various modifications and substitutions can be made to the embodiments described above without departing from the scope of the claims.
