Herbie the Mousebot is a 9-volt battery-powered light-following robot that loves to chase flash light beams. What sets aside the new version is that it can see much better now - and reacts to both LED and incandescent light. Cats ask for him by name!

And with it's enhanced functional whiskers and tail sensors, it doesn't get stuck in corners or under obstacles while chasing those lights around. Cats ask for him by name! These little robots are so quick, you (or your four legged friends*) will have to run to keep up to them!

Originally invented by Randy Sargent, Herbie was built from spare parts as an entry for a robot competition. Herbie is such an elegant, clever design using very few parts, it's been featured in as a construction project in "Junkbot, Bugbots, and Bots on Wheels", "Absolute Beginner's Guide to Robots" and "MAKE" Magazine.
