Just another Sandwich from David Cook's book. 'Ham' because it has been used for extensive demonstrations by ChiBots at various events. No matter how creative, interesting or amazing other robots are, sandwich still grabs the public's attention because it's a Ziploc container with motors and blinkin' lights.
* Sorry, I forgot what I named it.
This was my entry into the Fall 2006 Table Top contest. It's pure Lego-NXT. It goes to the end of the table and back (without falling off!) and waves a Chibot's flag on it's way back while repeating "Yipee!". It got a perfect score, but came in fourth in speed. This motivated me to buy bigger wheels.
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.
