Abstract:This paper mainly introduces the construction of a triangle omnidirectional wheel autonomous positioning robot chassis. It includes the selection of omni-directional wheel, the introduction of power system and the selection of robot positioning system, and complete the design and strength analysis of the robot chassis structure. The motion characteristics of the triangle chassis are analyzed, and the speed calculation method of each omni-directional wheel in the case of translation and rotation is given. The control analysis of robot motion is completed, and the control flow is given. Finally, a physical model is built, it runs smoothly and can realize the chassis rotation in the process of movement. The accuracy of motion position is within ±20 mm, The expected goal is achieved, which verifies the accuracy of the design.
Key words:triangle omnidirectional wheel;robot;chassis;autonomous positioning
