This project combines two principles together. We use magnetic field and rotation movement. We drive the wheel with magnets by arm with one magnet which push and poll it from magnets on the wheel.

There are two ways which we went. One is use electric arm which is driven by impulses from photo – sensors, which are stuck on circuit. The other is we used small wheel, which is connected by strap through transmission. Advantage of those systems is precise control.
