2 Touch Sensors
In essence, this is Dave Baum’s BugBot, (No copyright infringement intended). I added an extra set of antennae (To be able to sense further up, so it wouldn’t get stuck under the bottom of a chair, counter, etc). I also made the speed faster in the program so it can run around the room a little more efficiently.
Building instructions for Bugbot are found on page 109 of Dave Baum’s Definitive Guide to Lego Mindstorms Robots
