Omni Directional Soccer Player Robot - Utah ECE
Omni directional robots usually use special wheels. These wheels are known as omni directional poly-roller wheel. The most common wheels consist of six spindles like rollers which can freely rotate about their rotation axis (Fig. 2) (Asama, 1995, Watanabe, 1998). Fig. 2 Omni directional poly-roller wheel ...

COBOTS: ROBOTS FOR COLLABORATION WITH HUMAN OPERATORS
Motion at all. The wheel is not a caster in the conventional sense. Instead, it has a straight-up shaft like a unicycle, but this shaft is instrumented with a force sensor. If the sensor detects forces perpen-dicular to the wheel’s rolling direc-tion, the wheel is steered (by a motor) to minimize these forces. In effect, the wheel turns so ... Visit Document

Modeling And Adaptive Control Of An Omni-Mecanum-Wheeled Robot
Wheel is designed with passive rollers mounted around the wheel circumference at an angle of 45 degrees to the wheel plane, thus it allows for in place rotation with small ground friction and low driving torque.

And/or horizontal vibrations in many types of omni-directional wheels with passive rollers, this feature of no gap (or negligibly small gap) is important in re-duction of vibration during the wheel operation. In addition, the radii of rollers can be increased in this wheel, which enables the wheel to surmount a higher bump. ... View Document
