[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 5 This utility model provides a technical solution: an all-terrain delivery robot, including a torso mechanism 1, a wheeled movement mechanism 2, a legged movement mechanism 3, and a control mechanism 4. The torso mechanism 1 is used to place goods during delivery. The control mechanism 4 is located at the top of the torso mechanism 1 and is used to control the robot's movement and select between wheeled and legged movement modes according to different terrains. For example, on a smooth road, the robot is controlled to be in wheeled movement mode, and the legged movement mechanism 3 is in a folded state, with the wheeled movement mechanism 3 driving the robot to move quickly. When encountering stairs or obstacles, the robot is controlled to be in legged movement mode, at which time the wheeled movement mechanism 2 is folded, and the robot moves using the legged movement mechanism 3.

[0029] In one embodiment of this invention, the control mechanism 4 uses a general-purpose brain (master2000) as its core. This general-purpose brain possesses powerful perception capabilities, enabling it to quickly and accurately collect information about the surrounding environment, including obstacles, pedestrians, and road conditions. Through real-time analysis and processing of this information, the delivery robot can make more informed decisions, such as choosing the optimal delivery route and avoiding congested areas and dangerous zones, thereby improving delivery efficiency and safety. This general-purpose brain provides high-precision navigation and positioning functions, ensuring the delivery robot accurately reaches its destination in complex environments. This is particularly important for delivery tasks in complex scenarios such as high-rise buildings, underground parking lots, and narrow streets in cities, effectively reducing delivery errors and delays. With increased usage time, the general-purpose brain master2000 can continuously learn and accumulate experience, adaptively adjusting to different delivery scenarios and tasks. For example, it can dynamically optimize delivery routes and strategies based on factors such as traffic conditions and weather changes at different times, improving the robot's overall performance and adaptability.

[0030] In one embodiment of this invention, the torso mechanism 1 includes a housing 11 and robotic arms 12 disposed on both sides of the housing 11. The robotic arms 12 are located on both sides of the housing 11 in the direction of travel and can extend to both sides using the housing 11 as a fulcrum. When the robot is in a wheeled movement state, the robotic arms 12 can prevent the robot from tilting to the side. The housing 11 is equipped with object detection sensors, such as pressure sensors or infrared sensors, for detecting whether there is cargo inside the housing 11. A battery module is also provided inside the housing 11 for powering this invention.

[0031] In this embodiment, the robotic arm 12 includes a humerus 121 and a radius 122. The humerus 121 is rotatably mounted on a housing 11. Specifically, one end of the humerus 121 is hinged to the housing 11, and the other end of the humerus 121 can move up and down with the hinge point on the housing 11 as a fulcrum. One end of the radius 122 is hinged to the free end of the humerus 121, and the other end of the radius 122 can move back and forth with the free end of the humerus 121 as a fulcrum.

[0032] In this embodiment, the bottom end of the torso mechanism 1 is provided with a joint shaft 5.

The drive wheel 21 is foldably mounted on the joint shaft 5. When moving on flat ground, the drive wheel 21 extends to contact the ground, serving as the driving part for the robot's movement. The driven wheels 22 and the drive wheel 21 form a triangular structure, which keeps the robot stable during movement.

[0034] In this embodiment, the wheeled movement mechanism 2 also includes a central hip joint cruise motor 23 and a central hip joint pitch motor 24.

[0036] In this embodiment, specifically, the central hip joint pitch motor 24 is mounted at the bottom of the central hip joint cruise motor 23 via a connector. The central femur 25 is connected to the drive shaft of the central hip joint pitch motor 24. The central hip joint pitch motor 24 changes the height of the housing 11 above the ground by controlling the pitch angle of the central femur 25, facilitating passage over surfaces with low obstacles. The drive wheel 21 has a built-in hub motor as a power source, providing propulsion for the robot. When the robot is in a legged movement state, the central hip joint pitch motor 24 can also control the central femur 25 to move closer to the housing 11, causing the wheeled movement mechanism 2 to be in a folded state.

[0037] In one embodiment of the present invention, the foot-type moving mechanism 3 includes a foldable left moving carrier 31 and a foldable right moving carrier 32. Both the left moving carrier 31 and the right moving carrier 32 are connected to the joint shaft 5, and the driven wheels 22 are respectively mounted on the left moving carrier 31 and the right moving carrier 32.

Further, the drive end of the left hip joint cruise motor 315 is installed in the second mounting hole 52 to drive the left hip joint 311 to simulate the movement state of the human hip joint. The left hip joint pitch motor 316 is installed at the bottom of the left hip joint 311, and the top of the left humerus 312 is connected to the left hip joint pitch motor 316. The left hip joint pitch motor 316 controls the pitch angle of the left humerus 312 to simulate the movement of the human thigh.

[0040] In this embodiment, specifically, the left tibia 313 is hinged to the left femur 312, the top end of the left tibia 313 is hinged to one end of the guide rod 318, and the other end of the guide rod 318 is hinged to the drive shaft of the left knee joint motor 317. The rotation of the left knee joint motor 317 controls the guide rod 318 to drive the left tibia 313 to move.

[0041] In this embodiment, specifically, the left tibia 313 is also connected to two left fibulae 319.

For example, a crank is provided at the drive end of the left ankle joint cruise motor 320, and the left fibula 319 is hinged to the crank. The other end of the left fibula 319 is hinged to the upper end of the left foot 314 via a hinge. The left ankle joint cruise motor 320 controls the left foot 314 through the left fibula 319 to simulate the foot position during human walking.

[0042] In one embodiment of this utility model, the structure of the right-moving vehicle 32 is the same as that of the left-moving vehicle 31, and will not be described in detail here.

[0043] It should be noted that the motors in the embodiments of this application are all robot joint motors used for robot joint movement.
