Take a look at the incredible quickness of some of these autonomous sumo wrestling robots!
(Autonomous Sumo Robot Wrestling Video)
Some of the bots in the robot sumo video below are very fast and some of them are very slow and powerful. The fast bots move seriously fast around the small circle and on occasion some of the autonomous bots are unable to tell where the end of the circle is and fall off themselves. It appears that the slower and more powerful bots that use suction of some sort to stick to the circle surface are the ideal sort.
The fast bots are unable to move them off the circle whilst the slow and lumbering bot easily pushes some of the smaller, faster bots out of the circle. The bots each have a different sort of weaponry and the video is certainly entertaining if you have a few minutes to watch. The final match turns out to be speed vs. power and the two bots are very closely matched.
Science fiction readers may recall Rolem, the exercise partner of Konstantin Kharageosis, the main character from This Immortal, created by Roger Zelazny in 1966.
Off in the distance, I heard a scream. 'Stop it, Hassan, it's not supposed to do that!'
Which meant that I was Conrad, and that I was in Egypt, and that the expressionless face before me was therefore that of the golem-wrestler, Rolem, a creature that could be set for five times the strength of a human being, and was probably so set, a creature which could be given the reflexes of an adrenalized cat, and doubtless had them in full operation.
