Problems solved by technology

[0005] At present, in order to adapt to rough roads and increase the friction with the ground, many obstacle-crossing robots use discontinuous rims with complex structures. Moreover, such wheels will produce polygonal effects when driving on regular flat roads, and the smoothness of movement is very high. Poor, high requirements for sensing and control

Abstract

The invention discloses an obstacle-jumping robot provided with variable diameter wheels, comprising a left wheel component (1), a left wheel driving component (2), a right wheel component (3), a right wheel driving component (4), an overturning component (5), an overturning driving component (6) and a chassis component (7), wherein the left wheel component (1) is connected with the left wheel driving component (2) by a left wheel shaft (101), the right wheel component (3) is connected with the right wheel driving component (4) by a right wheel shaft (301), and the left wheel driving component (2), the right wheel driving component (4), the overturning component (5) and the overturning driving component (6) are installed on the chassis component (7). The robot not only can keep the minimum wheel diameter to stably drive on the flat ground by continuous smooth rims, but also can change the diameters of the wheels to span obstacles with different heights or drive on the rugged ground. Furthermore, when the robot comes across the situation that the wheels are difficult for spanning the obstacles, the counter acting force between an overturning arm and the ground can be utilized, so that the upward climbing capability of the robot can be improved to a certain extent.

Description

technical field [0001] The present invention relates to a robot structure. More specifically, it refers to an obstacle-surmounting robot with variable-diameter wheels. Background technique [0002] A robot is a machine device that performs work automatically. It can accept human command, run pre-programmed programs, and act according to principles formulated with artificial intelligence technology. Its mission is to assist or replace human work in jobs such as manufacturing, construction, or hazardous jobs. [0003] Wheels are the most popular locomotion mechanism in general mobile robotics and human transportation vehicles. Because the structure of the wheel mechanism is reliable, high-speed and stable, and the energy utilization rate is high, and its production can be realized with relatively simple machinery. However, as human beings continue to expand their space for activities—exploring the universe and developing the ocean—it is difficult to walk on traditional whe...
