The Gym Lifting is built from the Lego Wedo 2.0 educational kit. The drive is made on a spur gear. The lifting and lowering of the weight in the guides occurs due to the operation of the crank mechanism. The distance sensor registers the number of lifts/lowers of the weight; a counter algorithm has been compiled in the software environment.
The set includes step-by-step building instructions and an example of program (in Lego Wedo 2.0 environment).
