INTRO Mini Sumo Tournament 2013: Lots of Fun!

It was Friday the 13th, and it was Sumo Battle Day :-). After 3 months of tinkering, hacking and creatively improving the Mini Sumo Bots, finally the the course tournament took place.

Get Ready

With using a different room, every team had a chance to warm up and recalibrate the sensors for the new environment.

The time was used to apply last-minute changes and improvements too, plus to record the last Robo Portraits.

All robots have to fit 10×10 cm (no height limits), and can have a maximum mass of 500 g. Groups challenged each other to comply with the limits. The ‘Swiss’ tournament style was used and scores recorded on With 21 bots, after 5 rounds the winner(s) have been determined. Words cannot express all the fun and hilarious scenes during the battles:

  1. Be prepared to lose your tires!
  2. Never forget to turn on power first 😉
  3. A battle can change in the last seconds!
  4. Robots are able to dance with each other?
  5. Don’t run off the Dohyo yourself!
  6. Tighten your batteries!

  1. Erich,
    Fantastic job with the class. I wished I could have gotten full class participation like that when I was teaching. Keep up the good work.
