“Stupid Robot” contest

“Stupid Robot” contest

I like “dumb bots” (a.k.a. BEAM robots) as much as the next analog electronics fan, but Baca RoboCup is something entirely different. These baca (“foolish” or “stupid”) robots are meant to be as idiotic as possible and must be “useless to society,” in fact, the biggest chucklebot is voted the winner. BTW: It also states […]

Looking at the images close up, you can see this is an insta-bot, made with just the two servos, some coat hanger, and zip ties.

It’s powered by two 9v batteries wired in series and controlled by the arduino through transistors. I showed this off at the UrHo Talks 2 event last […]

By Jérôme Demers The Beetlebot is a very simple little robot that avoids obstacles on the floor without using any silicon chip — not even an op-amp, and certainly nothing programmable. Two motors propel the bugbot forward, and when one of its feelers […]
