Lecture 2: Robot Sumo Competition Rules

 As the basis for our competition, we will use the FSI – All Japan Sumo Tournament rules, as published at: e/out/outa0000.html#3  A quick summary: Match Length: 3 minutes Ring (Dohyo)Diameter: 154 cm (5 feet) Main Objective: Force Opponent from Dohyo

 Max Cost: $800 (this is my rule)  Mass : 3 kg maximum (6.6 lbs)  Dimensions :  Length: 20 cm (7.9 inches)  Width: 20 cm  Height: No limit  Restrictions:  Robot must NEVER present a hazard to humans  Robot must demonstrate at least some mobility in the Dohyo  Robot must have a means of starting that will initiate a minimum of 5 seconds of delay  Cannot use “sticky” material in contact with Dohyo, or deface the Dohyo in any way  Cannot eject, fire or throw any material, whether gas, liquid or solid

 The BRICK – many tires for maximum traction, extremely low to the ground on all sides (to avoid getting scooped), some ability to push opponent  The PUSHER – quick and agile, very low front end to get under opponent, tip him and drive him out of ring  The SCOOPER – scoop arm on the front (able to raise to vertical to meet length restriction), intended to lift opponent off its wheels

 Teams: Team 1: Chris Mason, Emily Howe, Ger Vue Team 2: Jeff Torgerson, Nick Schmitz, Shoua Vang, Team 3: Richard Allen, Dana Gorg, Chee Lee Team 4: Henok Araya, Jake Clifton, Aamani Gundu  Need to find a time to meet with me every week

 Identify a kit from which to start building your sumo-bot  Be mindful of the $800 limit on total cost  Determine a basic strategy for competition – Pusher design, etc  Be aware that most kits are intended for the 500 gram weight class (Would we rather do that?)
