In the past log I started working on a robot that would be used for my video and also demo the Smart Motor Driver (SAMI) in a real life application. Here are the results :)

I am using a Pololu track set, a custom made laser cut chassis an a bit of cardboard. 

The robot doesn't have any sensor or communication with the outside world. It would navigate a maze completely using pre-programmed distances on the smart motor drivers.

This will be the maze for my demonstration:

Edit: after a few tests I realised that tracks where slipping on the course surface and is almost impossible to correct that unless I use a IMU sensor. So I decided to make a new robot for the demos:

This idea will return later using an IMU to complement SAMI.
