A new prototype: Trevor V2

We built a new prototype made of Lego. We decided to equip Trevor with a new anti-block system that is reversing the rotation direction of one of the 2 rear wheels. The objective is to avoid to get Trevor blocked when hitting an obstacle.

We used gears and toothed racks to transform the translation of the front part when hitting the wall into a rotation that is transferred to the rear part where the rotation is transformed back to a translation perpendicular to the initial one. This final translation moves the back part of Trevor, aligning gears that reverse the rotation of the wheel.
