The Harvester is built from the Lego Wedo 2.0 educational kit. The harvester’s drive (moving forward or backward) is implemented in a bevel gear. To transmit rotation to the reeler, a belting is used. To control the movement, a worm gear with a tilt sensor is installed – the position in that the sensor sets – is encoded in the direction of movement – forward, backward or stop.
The set includes step-by-step building instructions and a example of program (in Lego Wedo 2.0 environment).
