The adhesion of your robot on the flool depend on the material used. Let’s try to find the best grip!

Each wheel and each material have a different friction

Plastic and wood have a bad adhesion.

Rubber and hide have a very good frection

The Chassis

Build-It-Yourself.com

The chassis is the base of your robot. All the modules are going to be cliped on it. So it has to

be strong.
