Problems solved by technology

[0004] The purpose of the present invention is to overcome existing in the prior art if if the wheel on this robot chassis is not coplanar, the relative ground normal pressure of each omnidirectional wheel just exists difference so, if at least one wheel appears positive Insufficient pressure, or when the ground is uneven, the wheels cannot be adjusted, resulting in slipping, which makes the friction of each wheel relative to the ground inconsistent, which will lead to the wrong final speed direction or incorrect path, causing the robot to slip and deflect during motion. Inconsistent with the program output path, the above-mentioned shortcomings that cannot meet the requirements of precise movement, provide an omnidirectional mobile chassis and its leveling method

Abstract

The invention discloses an omnidirectional moving chassis which comprises a frame, a driving system and a control system. At least three omnidirectional wheels are arranged on the frame, at most two omnidirectional wheels are fixedly connected to the frame, all of the rest omnidirection wheels are connected with a support, one end of the support is hinged on the frame while the other end of the same is connected on the frame through an adjusting part, the adjusting part can adjust the other end, connected with the same, of the support to move up and down relative to the frame, the driving system is connected with each omnidirectional wheel, and the control system controls the driving system to drive the omnidirectional wheels to rotate. By using the chassis, the adjusting part can adjust support up and down, in other words, adjusting up-down positions of the omnidirectional wheels to enable all omnidirectional wheels to be in a same plane, positive pressure of the omnidirectional wheels relative to the ground is ensured identical, in other words, friction force of the omnidirectional wheels relative to the ground is ensured identical, and resultant speed direction and program output path of the omnidirectional wheels are enabled to be uniform to accurately control movement. The omnidirectional moving chassis is simple and compact in structure, convenient to connect and use, good in acting effect and low in cost.

Description

technical field [0001] The invention relates to a chassis, in particular to an omnidirectional mobile chassis and a leveling method thereof. Background technique [0002] Robots are widely used and developed rapidly, and have entered all walks of life and our lives. Some special-purpose robots, such as sports robots, require sensitive movement, timely braking, stable operation, and omnidirectional movement. [0003] To achieve omnidirectional movement, it will be applied to omnidirectional wheels. The movement principle of this wheel is to determine the final speed direction of the robot by the synthesis of the speed direction of each wheel. The program controls the forward and reverse rotation and speed of each wheel. During operation, if the wheels on the chassis of the robot are not coplanar, the positive pressure of each omnidirectional wheel relative to the ground is different, then if there is at least one wheel with insufficient positive pressure, or if the ground is ...
