The Tower Crane is built from the Lego Wedo 2.0 educational kit. The drive of the cable winding system is implemented on a combination of three gears: bewel, belt and spur. The rotation of the crane around its axis for positioning the load is carried out using a handle that drives the worm gear. Raising and lowering the load is set by the position of the tilt sensor.
The set includes step-by-step building instructions and an example of program (in Lego Wedo 2.0 environment).
