Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] see Figure 1 ~ Figure 3 Introduce the overall structural composition of the variable structure robot of the present invention: In order to realize the changeable chassis structure of the variable structure robot, its main mechanism includes a steering mechanism, a telescopic mechanism, and a forward mechanism, which are explained separately below:

[0020] The steering mechanism consists of two upper and lower gear turntables fixed on the main frame of the car body through cross roller bearings, and the drive motor and worm gear reducer fixed on the frame drive the gear turntables to rotate at a certain angle, so as to realize the rotation of the axle around the center of the car body. Rotation, on the one hand, the worm gearbox is used to ...

Abstract

An object of the present invention is to provide a conveying robot with variable chassis, which belongs to the robot field. As that robot carry objects, the X-shape structure of the vehicle chassis isautomatically changed by acquiring the size of the object, and the size of the vehicle body is changed by axial expansion and contraction so as to adapt to the size of the object to be carry. When the robot is unloaded, it can pass through the narrow workspace smoothly by changing its own structure. The variable structure transporting robot of the invention processes the surrounding environment information through a multi-sensor information fusion technology, and the embedded system thereof is realized by adopting a state machine mechanism. Its motion control decision can be improved gradually by reinforcement learning. As that chassis adopt an X-shaped structure, the variable-structure conveying robot of the invention can rotate around the cent of the vehicle body and can realize the axial movement of the vehicle axle. The invention can conveniently and quickly realize obstacle avoidance in a narrow environment, and can recognize and carry goods of different sizes. The design is novel in structure, strong in adaptability and convenient to travel.

Description

technical field [0001] The invention relates to a variable structure handling robot, which belongs to the field of intelligent robots. Background technique [0002] In recent years, handling robots have been widely used in various fields. Although they have different forms in structural design, there are few handling robots with variable structures at present. There are relatively few studies on variable-structure robots. However, in the face of harsh and complex working environments, higher requirements will be put forward for the structure of robots. Therefore, variable structure has become a topic of great research value. The size of traditional piggyback robots can only be fixed. For example, Amazon acquired the robotic warehousing business of Kiva, an automated logistics provider, for $775 million in 2012, and transformed its Kiva robot into use. In the company's warehouse, the handling of goods can effectively reduce logistics costs and improve the efficiency of goo...
