Oogway, a Sumo Robot

In November 9, 2011, sumo robots fought in a dohyō specially built for them in the Expo Robótica UBB 2011 at Universidad del Bío-Bío, Concepción, Chile.

The Oogway robot was made with parts of the construction and educational fischertechnik® kits, acrylic and other electronic components. Its name was in honor of the master Oogway, the Galapagos giant tortoise of Kung Fu Panda (2008) film.

The most important features of this robot are:

  • 3.72 lb (1.69 kg) body weight.
  • Two crawler tracks with four servo motors 9 V, 0.465 A of maximum current consumption, 338 rpm, 8.4 N·cm, 25:1 reduction as the traction system.
  • Infrared sensors to keep it inside the circular area.
  • Touch sensors to know what side of it was being attacked.
  • Size and shape to maximize the contact area, but not to made it easily discoverable.
  • An program to attack and defend.

Oogway was planned, designed and made in only eight days!

Fighting Rules

The winner of a sumo match was the first wrestler in forcing its opponent to leave the circle area. Other way was turn the opponent. It was necessary to win three at least two battle to advance to the final phase.
