The robot can calculate the relative distance from the object more accurately, which is beneficial for obstacle avoidance and item grabbing. In addition, in a business hotel, the robot may encounter some obstacles blocking its vision during movement. If one camera fails or is blocked, the other camera can still provide visual information, improving the robustness of the robot's vision system. An installation seat 107 is provided on the other side of the head of the vehicle body 101, and the robotic arm assembly 2 is provided on the installation seat 107. The robotic arm assembly 2 is used to adjust the position of the robotic claw 3.

[0034] As Figure 4-6As shown, in this embodiment, the robotic arm assembly 2 further includes a turntable base 201 disposed on the mounting base 107. The top of the turntable base 201 is axially connected to one end of the first robotic arm 202 by a first motor 206. The other end of the first robotic arm 202 is axially connected to one end of the second robotic arm 203 by a second motor 207. The other end of the second robotic arm 203 is axially connected to one end of the third robotic arm 204 by a third motor 208. The other end of the third robotic arm 204 is axially connected to the fourth robotic arm 205 by a fourth motor 209. A fifth motor 210 is disposed on the fourth robotic arm 205, and the fifth motor 210 is axially connected to the robotic claw 3. The first motor 206, the second motor 207, the third motor 208, and the fourth motor 209 are all rotary motors, and the fifth motor 210 is a telescopic motor. The first motor 206 controls the horizontal rotation of the first robotic arm 202. The second motor 207 controls the up-and-down rotation of the second robotic arm 203. A rotating shaft connecting sleeve 211 is provided at the connection between the second robotic arm 203 and the third robotic arm 204. A square groove 212 is formed through the rotating shaft connecting sleeve 211. The end of the second robotic arm 203 is embedded in the square groove 212. The side wall of the rotating shaft connecting sleeve 211 is provided with the third motor 208, and the third motor 208 controls the up-and-down rotation of the rotating shaft connecting sleeve 211. The output shaft 213 of the third motor 208 penetrates through the rotating shaft connecting sleeve 211 and the second robotic arm 203. Through holes 214 are symmetrically formed on both sides in the square groove 212. The through direction of the through holes 214 is perpendicularly arranged relative to the through direction of the square groove 212. The third robotic arm 204 has a fork-shaped structure. The rotating shaft connecting sleeve 211 is embedded in the fork-shaped structure of the third robotic arm 204 and is rotationally connected to the third robotic arm 204 through the through holes 214. Through the structure of the rotating shaft connecting sleeve 211, the third robotic arm 204 can rotate along the rotation direction of the third motor 208 and can also rotate in a direction relatively perpendicular to the rotation direction of the third motor 208. The fourth motor 209 controls the rotation of the fourth robotic arm 205. The robotic arm assembly 2 of this robot is equipped with the first motor 206, the second motor 207, the third motor 208, and the fourth motor 209. Multiple motors can more precisely control each joint of the robotic arm, providing better force control and motion accuracy. In addition, by directly configuring motors at each joint, the use of mechanical transmission components can be reduced, the mechanical structure can be simplified, and the efficiency and reliability of the overall system can be improved.

[0035] As Figure 4 , 5As shown in FIGS. 6 and 7, in this embodiment, the fifth motor 210 is axially connected to the robotic claw 3 through the sleeve 215. The sleeve 215 is disposed perpendicular to the third robotic arm 204. The robotic claw 3 further includes a pull rod 31 sleeved on the sleeve 215. A limit sleeve 32 is movably sleeved on the pull rod 31. A plurality of claw roots 35 are evenly arranged on the outer side wall of the limit sleeve 32. Each claw root 35 is connected to the claw tip 36 through an inner connecting rod 37 and an outer connecting rod 38. The inner connecting rod 37 and the outer connecting rod 38 are relatively parallel. A transmission sleeve 33 is fixedly arranged on the pull rod 31 below the limit sleeve 32. One end of a transmission rod 34 is rotatably connected to the side wall of the transmission sleeve 33, and the other end of the transmission rod 34 is rotatably connected to the middle position of the inner connecting rod 37. The number of the transmission rods 34 is equal to the number of the inner connecting rods 37. The robotic claw 3 of this robot can actively press the elevator button to go up and down the building and flexibly grab items. Specifically, the fifth motor 210 is a telescopic motor and is axially connected to the robotic claw 3 through the sleeve 215. The pull rod 31 is arranged inside the sleeve 215. The fifth motor 210 pulls the pull rod 31 to contract inward, causing the limit sleeve 32 to move downward along the pull rod 31. Since the transmission sleeve 33 is fixed on the pull rod 31, and the two ends of the transmission rod 34 are respectively connected to the transmission sleeve 33 and the inner connecting rod 37, when the limit sleeve 32 moves downward, it pushes the inner connecting rod 37 and the outer connecting rod 38 to contract and gather together. The claw tips 36 connected by the inner connecting rod 37 and the outer connecting rod 38 also contract and gather together accordingly. All the claw tips 36 are tightly closed together, which is beneficial for grabbing items. When all the claw tips 36 are tightly closed to the minimum, the elevator button can be pressed to go up and down the building. When unloading items, the fifth motor 210 pushes the pull rod 31 to extend outward, causing the limit sleeve 32 to move upward along the pull rod 31, pulling the inner connecting rod 37 and the outer connecting rod 38 to expand outward. The claw tips 36 connected by the inner connecting rod 37 and the outer connecting rod 38 also expand outward accordingly. The inner connecting rod 37 realizes the transmission control of the movement of the claw tips 36, and the outer connecting rod 38 further fixes the claw tips 36 to prevent the claw tips 36 from loosening. Each claw tip 36 is provided with a rounded corner. The length of the minimum stress surface after all the claw tips 36 are closed is less than 20 mm. According to the standard of the China Elevator Association, the minimum size of the movable part of the elevator button should be an inscribed circle with a diameter of 19 mm. Therefore, the stress area after the claw tips 36 are closed is smaller than the stress area of the elevator button, preventing the outer periphery of the elevator button from being stressed.

[0036] As Figure 3 shown, in this embodiment, a counterweight 108 is arranged at the tail of the vehicle body 101 to prevent the robotic arm from tipping over when grabbing too heavy items. A lighting lamp 109 is arranged on one side of the second vision camera 106 for lighting in a dark environment. A storage box 110 is arranged on the top of the vehicle body 101 for storing items during transportation.

[0037] The working principle of the technical solution provided by the present utility model is as follows:

[0038] When the robot transports items in a business hotel and goes up and down the elevator, it drives to one side of the item. The first vision camera 104 and the second vision camera 106 sense the three-dimensional information of the object, including distance, shape, and position. The robot can more accurately calculate the relative distance from the item. The robotic arm assembly 2 moves the robotic claw 3 above the item. In the robotic arm assembly 2, the first motor 206 controls the horizontal rotation of the first robotic arm 202, and the second motor 207 controls the up-and-down rotation of the second robotic arm 203. A rotating shaft connecting sleeve 211 is provided at the connection between the second robotic arm 203 and the third robotic arm 204. A square groove 212 is opened through the rotating shaft connecting sleeve 211. The end of the second robotic arm 203 is embedded in the square groove 212. A third motor 208 is provided on the side wall of the rotating shaft connecting sleeve 211. The third motor 208 controls the up-and-down rotation of the rotating shaft connecting sleeve 211. The output shaft 213 of the third motor 208 passes through the rotating shaft connecting sleeve 211 and the second robotic arm 203. Through holes 214 are symmetrically opened on both sides in the square groove 212. The third robotic arm 204 has a fork-shaped structure. The rotating shaft connecting sleeve 211 is embedded in the fork-shaped structure of the third robotic arm 204 and is rotatably connected to the third robotic arm 204 through the through holes 214. Through the structure of the rotating shaft connecting sleeve 211, the third robotic arm 204 can rotate in the direction of the rotation of the third motor 208 and can also rotate in a direction perpendicular to the rotation direction of the third motor 208. The fourth motor 209 controls the rotation of the fourth robotic arm 205. The robotic claw 3 is provided on the fourth robotic arm 205. Therefore, the robotic arm assembly 2 realizes the control of the position movement of the robotic claw 3.

[0039] When the robotic claw 3 moves above the item, the fifth motor 210 pulls the pull rod 31 inward to contract, prompting the limit sleeve 32 to move downward along the pull rod 31. Since the transmission sleeve 33 is fixed on the pull rod 31, both ends of the transmission rod 34 are respectively connected to the transmission sleeve 33 and the inner connecting rod 37. As the limit sleeve 32 moves downward, it pushes the inner connecting rod 37 and the outer connecting rod 38 to contract and gather together. The claw tips 36 connected to the inner connecting rod 37 and the outer connecting rod 38 also contract and gather together. All the claw tips 36 are tightly closed to grasp the item. Then the item is moved into the storage box 110. The robot drives to the elevator hall and determines the position of the elevator button through the first vision camera 104 and the second vision camera 106. The claw tips 36 are tightly closed to the smallest size, and the elevator button can be pressed to go up and down the building. When the robot reaches the destination, it grabs the item from the storage box 110 for unloading. When unloading the item, the fifth motor 210 pushes the pull rod 31 to extend outward, prompting the limit sleeve 32 to move upward along the pull rod 31, pulling the inner connecting rod 37 and the outer connecting rod 38 to expand outward. The claw tips 36 connected to the inner connecting rod 37 and the outer connecting rod 38 also expand outward, completing the unloading of the item.

[0040] When the present utility model is actually in use, the universal rod 102 is a shaft-like component with two ends, and the two ends of the shaft are respectively connected to the driving mechanism and the universal shaft 42; the middle part of the universal rod 102 is also connected to the universal shaft 42 through the joint assembly 41, and is also directly connected to the wheel axle 44 through the elastic connecting piece 43; the universal shaft 42 and the wheel axle 44 are fixedly connected to the wheel 103 through a rigid bracket; the three wheels 103 connected by the universal shaft 42 and the elastic connecting piece 43 at the bottom of the universal rod 102 can freely rotate in multiple directions, and at the same time provide a stable supporting effect on the premise of using the minimum number of wheels, enabling the robot to move smoothly and freely in any direction; the elastic connecting piece 44 allows the wheels to absorb the impact force caused by the uneven ground and improves the driving stability; the length of the universal rod 102 can be adjusted according to the size of the robot chassis and the wheel layout to ensure the balance of the robot during movement.

[0041] The present utility model provides a robot equipped with a robotic arm; when the front wheel encounters an obstacle, the elastic connecting piece is compressed to the limit, and the rear two wheels provide support; after the front wheel crosses the obstacle, the elastic connecting piece stretches, and the front and rear wheels jointly support the middle wheel to pass through the obstacle; similarly, when the rear wheel encounters an obstacle, the elastic connecting piece is compressed again, and the front two wheels provide support to smoothly cross the obstacle. Through the coordinated cooperation of the three wheels and the wheel assembly, the robot maintains balance and realizes smooth obstacle crossing.

[0042] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present utility model.
