In the previous section you have seen the different types of wheels and their arrangements. Once you have decided on how many and what type of wheels your robot will have, you need to put in a plan on how to control them. Below described are few control mechanisms to drive and steer your robot. Differential Drive/Differential wheel: This is the most common control mechanism for robot builders, especially for beginners. The concept is simple; Velocity difference between two motors drive the robot in any required path and direction. Hence the name “Differential” drive. Differential wheeled robot can have two independently driven wheels fixed on a common horizontal axis or three wheels where two independently driven wheels and a roller ball or a castor attached to maintain equilibrium. There are three fundamental cases which can happen in a differential wheeled robot: Design, mechanical construction and control algorithm can never get any simpler than this driving technique, and the co
