Robot 2.1.2

This is my fully functional robot with its new circular base. It avoids walls and obstacles like a pro!

This robot just gets better and better.  Leave your thoughts in the comments section.

I also added an LED to the robot to show when it sees an obstacle. (not shown in picture)

New Base of Robot 2

This is what I'm up to in the next improved version of the robot. I'm making the base circular.
