Omnidirectional Wheel 4cm Diameter

Introduction

This is 4cm diameter Omnidirectional wheel with 8mm bore. Using OMW-01 wheel coupling these wheels can be used with any Plastic Gear Motors or Standard size servo motors such as NRS-995 and NRS-785 from NEX Robotics. With minor adjustment these wheels can also be used with any 6mm shaft DC Gear Motors.

Omni wheels are wheels with small discs around the circumference which are perpendicular to the rolling direction. The effect is that the wheel will roll with full force, but will also slide laterally with great ease. These wheels are often employed in holonomic drive systems.

They are often used in small robots. In leagues such as Robocon, Robocup etc. Many robots use these wheels to have the ability to move in all directions. Omni wheels are also sometimes employed as powered casters for differential drive robots to make turning faster. However, this design is not commonly used as it leads to Fishtailing.

Omniwheels combined with conventional wheels provide interesting performance properties, such as on a six wheel vehicle employing two conventional wheels on a centre axle and four omniwheels on front and rear axles.
