==Introduction==

The brush unit is controlled by a Teensy 3.2. In addition to the brush it also controls the movement of the front wheel.

The front wheel can lift the brush, to be able to pass cables on the floor and to move when the brush is off.

The front wheel is also a steering wheel, helping the differential drive when turning.
