Autonomous Sumo robots are self-propelled and self-controlled, without tethers. After positioning and starting the robot, no remote control, power, positioning, or other help can be provided. The robot must care for itself until the round ends.

How are Sumo robots controlled?

Autonomous Sumo robots are self-propelled and self-controlled, without tethers. After positioning and starting the robot, no remote control, power, positioning, or other help can be provided. The robot must care for itself until the round ends.

Are sumo robots remote controlled?

Powered by four AA batteries (not included) and featuring a built-in infra-red remote control, the Sumo-Bot is pre-programmed with the following behavior “built in” to jumpstart custom applications.

Are Sumo bots autonomous?

Each bot acts entirely autonomously based on certain pre-programmed behaviors, and although there are a few rules to be observed, the main restraints are simply on size and weight. Within these limits, bots can try a number of different tactics to try and knock their opponent out of the ring.

What are sumo robots used for?

The robots used in this competition are called sumobots. The engineering challenges are for the robot to find its opponent (usually accomplished with infrared or ultra-sonic sensors) and to push it out of the flat arena. A robot should also avoid leaving the arena, usually by means of a sensor that detects the edge.

How do Japanese sumo bots work?

The sumo robot sees its opponent with infrared. Because infrared beams are emitted straight ahead and the reflecting light from the opponent is used to detect its location, the field of vision is narrow. Installation of multiple sensors ensures a wider field of vision.

What can sumo wrestlers not do?

Punching, gouging, and kicking are prohibited, but slapping and tripping are allowed. It is legal to grab the “mawashi” (sumo belt) anywhere around the waist, but not in the groin area. Hair-pulling is also banned.

What is the size of a sumo robot?

Japanese-class Sumo robots may be 20 centimeters (7.87 inches) or less in width and 20 centimeters (7.87 inches) or less in depth. Rulers measuring the width and depth of a Mini-class Sumo robot

What are the rules for Sumo robots?

Another rule: Sumo Robots must not fly or generate lift to isolate themselves from the ring surface. The “no-fly” rule isn’t intended to prevent a robot from having a floating portion (such as a camera, sensor, flag, or distraction) nor to prevent jumping or other interesting behavior.

What is the sumo competition?

ACS: “The Sumo competition consists of a three minute round involving two robots. Within the three minute round there may be more than one bout. If a bout is won before the three minutes are up, the clock will be stopped and the robots replaced in their starting position for another bout.

Can a sumo robot drive out of the ring?

A surprising number of Sumo robots drive out of the ring without even being pushed. A well designed and built Sumo robot should be able to navigate the ring indefinitely without falling out. The flat black ring surface contrasts with the gloss white border so that a robot can easily use a light sensor to detect the edge.
