Zumo Robot with Magnetic Encoders

We are using robots to teach advanced embedded system programming at the Lucerne University (see “Sumo Robot Competition“). Students can buy the kit, and we are running out of available hardware. Time to produce a new series of robots :-). It took us a while to get to the next revision of the Zumo Robot, but finally the first one has been produced and assembled, and I think it is looking good :-).

Snow Plowing (Darth Vader) Sumo Bot

Finally, winter with lots of snow arrived in Switzerland. Getting up at 5am this morning to free up my front yard from the 25 cm snow which came down overnight, so I can drive my wife to work. She does not like driving in snow conditions, but it is fun for me :-). But lots of snow, I thought I could use a little helper bot:
