Wheeled propulsion is still the most popular and simplest way to move land-based mobile platforms. In the case of robots - whether amateur or fully professional - just two independent wheels will make it possible for the vehicle to move forward and backward, turn at any radius, and also rotate in place. However, this is still not all that can be expected from a wheeled robot. Interestingly, it only needs to include three motors and special 'Omni Wheel' type 'omni-directional' wheels to give the structure unlimited movement.
