The Scorpion is built from the Lego Wedo 2.0 educational kit. For the movement of the tail, a crank mechanism is used, as a result of which the tail makes reciprocating movements. A distance sensor is installed in the front of the model, which reacts to external influences.
The set includes step-by-step building instructions and an example of program (in Lego Wedo 2.0 environment).
