- Build the Caterpillar, Big Alice, and Small Alice.
- Build the Mushroom, the Caterpillar, the Little and the Big Alice
- The Caterpillar rotates on an axle on the cap of the mushroom.
a.)Build a mechanical construction
- Under the cap of the mushroom, the two Alices of different sizes can be moved forwards or backwards by means of an axial mechanism.
- Wherever the Caterpillar turns, the Alice is propelled forward.
b.) Build a programmable structure: using 1 basemount and 1 DC motor.
- On the mushroom stalk, 1 DC motor moves the Alices, so that the smaller or the larger Alice are moved forward.
- The robot's program starts automatically.
