[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1 to 9 As shown, this utility model provides a service robot, including a mobile chassis 1, a body 2, a gripping mechanism, and a vision component 4. The top of the mobile chassis 1 has a groove 11. The body 2 includes a thigh 21, a lower leg 22, and a platform 23. The first end of the thigh 21 extends into the groove 11 and can rotate relative to the groove 11 about a first direction. The first end of the lower leg 22 is connected to the second end of the thigh 21 and can rotate relative to the thigh 21 about the first direction. The bottom end of the platform 23 is located at the second end of the lower leg 22 and can rotate relative to the lower leg 22 about the first direction. The gripping mechanism includes a robotic arm 3, which is fixed to the top of the platform 23. The vision component 4 is fixed to the top of the platform 23. The first direction is... Figure 2 The X direction in the equation.

[0039] In its retracted position, the top of the mobile chassis 1 has a groove 11, into which the first end of the thigh 21 extends. The first end of the thigh 21 can rotate relative to the groove 11 with a first direction as its rotation center. The first end of the lower leg 22 also rotates relative to the thigh 21 with a first direction as its rotation center, reducing the space occupied by the body 2. Furthermore, the bottom of the platform 23 can retract relative to the lower leg 22 with a first direction as its rotation center, allowing the robotic arm 3 to retract. Additionally, the folding of the robotic arm 3 further reduces the space occupied by the service robot. During operation, the vision component 4 identifies the position of the object to be grasped. The mobile chassis 1 moves the body 2 closer to the object, the robotic arm 3 grasps the object, and then, through the combined action of the vision component 4, the mobile chassis 1, and the robotic arm 3, moves the object to the desired position, thus achieving the movement of the object. Therefore, in its folded position, it is convenient for storage; during transportation, it is convenient for transport; and during operation, the rotation of the lower legs 22 and upper legs 21 of the body 2 allows the robotic arm 3 to have a larger range of motion, extending its working range from the ground to a height of 1500mm, thus widening the grasping range and meeting user needs. It is highly adaptable. Furthermore, the service robot occupies relatively little space during operation. Fixing both the robotic arm 3 and the vision component 4 to the top of the platform 23 also prevents interference between the robotic arm 3 and the vision component 4 and the body 2, and facilitates the folding of the service robot.

[0040] Optionally, the mobile chassis 1 includes a chassis body and three wheels 12. The three wheels 12 are arranged in a triangle at the bottom of the chassis body and are used to drive the chassis body to move. This arrangement reduces weight and manufacturing costs, facilitates maintenance, and makes movement more stable.

The base 24 is fixed in the groove 11, and the first driving member 25 is fixed to the base 24.

Optionally, the first driving member 25 is a motor.

[0042] Optionally, the base 24 is provided with a first receiving cavity 241, and the first driving member 25 is disposed in the first receiving cavity 241. Disposing the first driving member 25 in the first receiving cavity 241 protects the first driving member 25 and prevents dust from falling onto the first driving member 25.

[0043] Optionally, the end of the first drive arm 211 near the lower leg 22 and the end of the first auxiliary arm 212 near the lower leg 22 together form a second accommodating cavity. The body 2 also includes a second drive member 26, which is located within the second accommodating cavity. The lower leg 22 includes a second drive arm 221 and a second auxiliary arm 222, which are located on opposite sides of the second drive member 26. The second drive arm 221 is fixed to the output end of the second drive member 26, and the second auxiliary arm 222 is rotatably connected to the thigh 21. The second auxiliary arm 222 is detachably connected to the second drive arm 221. With the above configuration, the first end of the lower leg 22 can rotate relative to the thigh 21 with the first direction as the rotation center, which facilitates the installation and removal of the lower leg 22, improves the structural stability of the lower leg 22, and facilitates support for the platform 23. In addition, placing the second drive member 26 within the second accommodating cavity protects the second drive member 26 and prevents dust from falling onto it.

Alternatively, a third crossed roller bearing is provided between the cavity wall of the second accommodating cavity and the output end of the second driving member 26, and a fourth crossed roller bearing 214 is provided between the second auxiliary arm 222 and the first auxiliary arm 212. By adding crossed roller bearings at both ends, the overturning moment of the body 2 can be strengthened, increasing the stability of the service robot and solving the problem of severe shaking caused by weight and speed in existing service robots, thus avoiding affecting the recognition, movement, and grasping effects.

[0045] Optionally, the fourth crossed roller bearing 214 is limited by a first annular cap 215 and a second annular cap 216. Specifically, the first annular cap 215 is fixed to the first auxiliary arm 212 by screws to press the first annular cap 215 onto the inner ring of the fourth crossed roller bearing 214, and the second annular cap 216 is fixed to the second auxiliary arm 222 by screws to press the second annular cap 216 onto the outer ring of the fourth crossed roller bearing 214.

[0046] Optionally, the body 2 also includes a third drive component 27, which is fixed to the second end of the lower leg 22 and is used to drive the platform 23 to rotate. Optionally, the third drive component 27 is a motor.

[0047] Optionally, the thigh 21 is connected to a first wire guide shell 213, which covers the thigh 21 and forms a first wire guide cavity. The lower leg 22 is connected to a second wire guide shell 223, which covers the lower leg 22 and forms a second wire guide cavity. The service robot also includes a first wire harness, which passes through the first and second wire guide cavities. By setting the first and second wire guide cavities, the trajectory of the first wire harness is restricted to avoid wear or even cutting of the first wire harness when the robot body 2 rotates. The first wire harness moves more reliably within the designed trajectory. In addition, the first and second wire guide shells 213 and 223 can serve a decorative and aesthetic purpose. Optionally, two first wire guide shells 213 are provided, each detachably mounted on the first drive arm 211 and the first auxiliary arm 212 respectively, forming two first wire guide cavities; two second wire guide shells 223 are provided, each detachably mounted on the second drive arm 221 and the second auxiliary arm 222 respectively, forming two second wire guide cavities. In this embodiment, the two ends of the first wire guide cavity corresponding to the first auxiliary arm 212 are connected to the first receiving cavity 241 and the second receiving cavity respectively, and the second wire guide cavity corresponding to the second auxiliary arm 222 is connected to the second receiving cavity. With this configuration, the first wire harness passes through the first receiving cavity 241, the first wire guide cavity, the second receiving cavity, and the second wire guide cavity, which can better restrict the trajectory of the first wire harness.

[0048] Optionally, the vision component 4 includes a support base 41, a support frame, a camera 42, and a second wiring harness. The support base 41 has a third wiring cavity 411 and a mounting cavity 412, with the mounting cavity 412 communicating with the third wiring cavity 411. The support frame is inserted into the mounting cavity 412, and the camera 42 is fixed to the support frame. The support frame has a fourth wiring cavity, which communicates with the third wiring cavity 411. The second wiring harness passes through the third wiring cavity 411 and the fourth wiring cavity and is connected to the camera 42. By setting the third wiring cavity 411 and the fourth wiring cavity, the trajectory of the second wiring harness is restricted to avoid wear or even cutting of the second wiring harness when the robotic arm 3 rotates, allowing the second wiring harness to move more reliably within the designed trajectory. In addition, by setting the third wiring cavity 411 and the fourth wiring cavity, the overall weight can be reduced, saving costs. Inserting the support frame into the mounting cavity 412 facilitates the installation of the support frame. In addition, the vision component 4 also includes an industrial computer 45, which is connected to the camera 42 via a second wiring harness.

[0049] Optionally, the support frame includes a frame body 43 and a mounting member 44. The frame body 43 is inserted into the mounting cavity 412, and the mounting member 44 is detachably connected to the frame body 43. The camera 42 is fixed to the mounting member 44. The frame body 43 has a first cavity 431, and the mounting member 44 has a second cavity 441. The second cavity 441 and the first cavity 431 together form a fourth cable passage cavity. By detachably connecting the mounting member 44 to the frame body 43 and fixing the camera 42 to the mounting member 44, it is convenient to disassemble the mounting member 44 and the camera 42. The second cavity 441 and the first cavity 431 together restrict the trajectory of the second cable harness, thus better controlling the second cable harness.

[0050] Optionally, the frame 43 extends vertically, and the mounting component 44 includes a horizontal part 442 and two inclined parts 443. The two inclined parts 443 are located at both ends of the horizontal part 442 and are inclined away from the frame 43. Two cameras 42 are provided, and each camera 42 is connected to one of the two inclined parts 443.

[0051] Optionally, platform 23 has two mounting positions, and robotic arm 3 can be selectively connected to one of the mounting positions. Robotic arm 3 includes base 31, such as... Figure 9 As shown, when the robotic arm 3 is in one of the mounting positions, the base 31 is perpendicular to the horizontal plane, as... Figure 8 As shown, when the robotic arm 3 is in another mounting position, the base 31 is parallel to the horizontal plane. The robotic arm 3 can be selectively connected to one of the mounting positions, allowing for quick changes in its posture to suit specific application scenarios and increase its applicability. Specifically, the platform 23 includes a platform body 231, a first connector 232, and a second connector 233. The first connector 232 is detachably connected to the side of the platform body 231. When the robotic arm 3 is connected to the first connector 232, the base 31 is perpendicular to the horizontal plane. The second connector 233 is detachably connected to the top of the platform body 231. When the robotic arm 3 is connected to the second connector 233, the base 31 is parallel to the horizontal plane.
