The Koala is built from the Lego Wedo 2.0 educational kit. Moving the koala up and down along the trunk of the eucalyptus is due to the winding of the cable. The cable reel is located on the output shaft of the worm gear. The distance sensor fixes the position of the koala at the top of the eucalyptus.
The set includes step-by-step building instruction and an example of program (in Lego Wedo 2.0 environment).
