Robot sumo wrestling at UNRobot
‘Pichirilo’, a small black robot in form of a powerful vehicle and built with proximity infrared and ultrasound sensors was the winner of this edition of UNRobot.Bogotá D. C., 12 de noviembre de 2015 — Agencia de Noticias UN-
A sumo robot has a number of sensors which allows them to distinguish black and white colors of the sumo rink.
The robots used in these competitions are 550 g and 3 k robots for the minisumo and sumo categories.
This aggressive robot was only one of many robots which participated in the UNRobot Sumo wrestling competition. This robot has protection bars and guards to push any competitor off the white line bordered sumo rink.
This National Mobile Robot Meeting called UNRobot 2015 was sponsored by the Universidad Nacional de Colombia (UNal) Bogotá Faculty of Engineering and supports mechatronics, robotics and automation, encouraging the search for innovative processes and also useful to society.
UNRobot gathers students from 25 high schools and 10 universities in Colombia to compete in several sumo wrestling categories including sumo and minisumo, as well as other line following and firebot competitions.
The sumo and minisumo categories use 3 kilo and 500 g robots which autonomously try to push their contender out of the sumo dojo. The competition strategy is devised before the competition through programming.
The line following category is a competition in which the robot that moves faster over a line on a flat surface without steering off wins the competition. There is also a competition on a multilevel track where the line passes through vertical obstacles.
In another competition called micromouse, participants must search for the exit in a maze in the least time possible.
UNal Mechatronic Engineering undergraduate Vanesa Sora explained that a sumo robot is built with a series of sensors which enable it to distinguish the black and white surface colors of the sumo rink, advancing on the black and stopping on the white in order to remain inbounds. They also have ultrasound or infrared proximity sensors which help them identify the position of the opponent. The sumo rink also has floor magnets to help the robots have more grip.
Another competition called Firebot, is a track with a series of heat obstacles to overcome and shut down the heat source in record time.
UNRobot Coordinator Sebastián Dussán said this event focuses mainly on mobile robotics through an open no-cost invitation and provides awards to continue supporting this area of knowledge.
This year the invitation was provided not only to the competition participants but also for showcasing new robotics technological developments.
This event was organized by the UNal Mechatronics Engineering Student Committee with support from the Institute of Electrical and Electronics Engineers (IEEE) was held between November 10 and 13, with an award ceremony on the last day of competition.
UNRobot is carried out on the UNal-Bogotá Luis Carlos Sarmiento Science and Technology Plaza.(Por: Fin/VMH/MLA/CA
