We're back with Trevor V5...

We decided to evolve our anti-block system because it would not fit very well for this new challenge.

So we selected an electric approach. We used an electric reverse switch. The principle is the following :

When the switch is in the initial position the rover goes forward and when the switch is in its other position the rover goes backward.

We used a recycled switch from a broken device. Let's think about the planet ;-)
