Omni-wheel introduction

Brief introduction of Omni-wheel

Omni-directional wheels are unique as they are able to roll freely in two directions .It can ether

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/backwards and rotation.Not being able to move side ways 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 it a highly maneuverable.Unlike normal non-holonomic

robot,the holonomic omni-directional robot can move in an arbitrary direction continuously

without changing the direction of the wheels.It can move back and forth,slidewaysmand rotates

at the same position.
