Markus shared his Omnidirectional remote controlled robot:
Recently, I got interested in omni wheels, so I built this little robot. The robot has three pairs of omni wheels. I covered each roll of the omni wheels with liquid rubber (plastidip) to get better traction. I bought the cheapest servos I could find and modified them for continuous rotation. The robot is powered by four eneloop NiMH batteries and controlled by an Arduino nano 3.0.
