@bobiej123 The top wheel is used as transmission. When it hits a wall it gives traction to the other wheel. Some sophisticated design is built that way that when colliding, the top section still moves (inertia). Then the transmission is reversed.
Ah, I see how it works. It's top heavy so when it hits something the gears it's driving on one side switch to the other side. Lol, at first I thought the third big gear was for driving on incase it flipped over.
Did you build that your self or did your mom help you?
