Mobile Robot Bases

Types of Mobile Robot Bases Ackerman Drive – typical car steering – non-holonomic

Types of Mobile Robot Bases Omni Drive – wheel capable of rolling in any direction – robot can change direction without rotating base Synchro Drive

Types of Mobile Bases Differential Drive – Two independently driven wheels on opposite sides of the robot – 3 DoF: pose = [x,y,Θ] – Holonomic: can be treated as a massless point that can move in any direction
