Abstract

The invention discloses an angle-controllable power differential omnidirectional wheel, and a control method and an omnidirectional moving platform thereof, and relates to the technical field of machinery manufacturing and assembly and intelligent control. The angle-controllable power differential omnidirectional wheel comprises a wheel frame main body, a rotary support bearing, two wheels, two elastic shaft couplers, two speed reducing motors, a gyroscope and a controller. According to the control method of the omnidirectional wheel, the rotating speed of two wheels is subjected to closed loop control so that the practical azimuthal angle of the omnidirectional wheel tracks the expected value; the flexible steering is realized; the cost is low; the omnidirectional moving requirements of the heavy equipment or cargo transportation can be met. The omnidirectional platform comprises the omnidirectional wheel and a platform bottom plate connected with the omnidirectional wheel through the rotary support bearing; the non-steering flexible movement of the platform bottom plate is realized.

Description

technical field [0001] The invention discloses an angle-controllable power differential omnidirectional wheel, a control method thereof and an omnidirectional mobile platform, and relates to the technical fields of mechanical manufacturing and assembly and intelligent control. Background technique [0002] At present, omnidirectional mobile platforms can realize the function of omnidirectional movement of vehicles, mainly including omnidirectional platforms using Mecanum wheels (hereinafter referred to as "Mike Wheels") and mobile platforms using special steering control mechanisms. [0003] The omnidirectional vehicle using the microphone wheel is flexible in steering and can move in any direction. Because it appeared earlier, the industry has studied it more deeply, the related control methods are relatively mature, and the motion accuracy is relatively high. Due to the complex design and structure of the microphone wheel, the high price of a single wheel set, and poor mai...
