52mm Omnidirectional wheel is unique as they are able to roll freely in two directions. It can either roll like a normal wheel or roll laterally using the wheels along its circumference. Omni-direction wheels allow a robot to convert from a non-holonomic to a holonomic robot. A non-holonomic robot that uses normal wheels has only 2 out of 3 controllable degrees of freedom which are, moving forward/backward and rotating. Not being able to move sideways makes a robot slower and less efficient in reaching its given goal. The holonomic Omni-directional wheels are able to overcome this problem, as it is highly maneuverable. Unlike a normal non-holonomic robot, the holonomic Omnidirectional robot can move in an arbitrary direction continuously without changing the direction of the wheels. It can move back and forth, sideways, and rotates at the same position.
