Together with two of my friends (Borys Cieszynski, Mariusz Barczak) we build a sumo robot named “Apatorek”. We spend about 4 hours every day for 2 years to make the robot. But it was worth, the robot twice won second prize in Sumo robots competition in 2007 and 2008. Competition was held by Poznan University of Technology. All together 44 teams from universities all over the Poland were registered for the competition. Our team was sponsored by Nicolaus Copernicus University and Apator company.
It is worth mentioning that we not only assembled the board by our self but also made the PCB by our self.
Robot was equipped with two MCUs ATMega 16 and ATMega 32, optoisolators, home made H – bridge, three wide angle ultrasonic distance sensors, two narrow angle IR distance sensors, four white line detectors – foto-transistor coupled with IR LED, two DC motors taken out of BOSCH cordless screwdriver.
Below a few pictures of the robot.
