Crawling Microbug by Velleman Inc.

The Crawiling Microbug is a light sensitive robot much like its sister the Running Microbug but with two add features. First, this Microbug has two speeds --crawl and normal. Second, additional to the two variable resistors or also called potentionmeter that control trim a third potentionmeter that controls the speed of both motors. This Microbug loves to chase the light (thanks to the two photoresistors). For a short demonstration watch my video.
