TuteBot is made from Lego Technic parts, Technic motors and relays. The design is straight from Mobile Robots: Inspiration to Implementation (First Edition, the Second Edition has a lot of problems). TuteBot, as in Tutorial Robot, moves forward until a bump sensor closes, then it backs up while turning for an amount of time determined by an R-C circuit, then moves forward again.

i'm just getting into robotics but hope to have something to show soon. i was a s/w developer at Bell Labs for 15 years, then for 6 years at a local startup company. i've been "self underemployed" for about 6 years now and enjoying not having a "regular" job.
