Let's Make Robots!

A fun little project! + extra upgrade!

it will avoid walls using two sensors

here is a small project, that I made with my friend ( Stefan )

if you are a real robot builder , you have alrady got all the stuff you´ll need

turn off your speaker if you get tired of the music ( Daft Punk - Around the World )

and now with upgrade to get a better grip = perfect turn then hitting a wall
