7. SumoBot Rules • The Match: • 1) Flip a coin to determine who positions their robot first in the ring • 2) Place the ‘bot in the ring as directed by the referee • 3) Press the start button on the bot when directed by the referee. • After 5 seconds the bot may begin moving (sound/light indicates robot working). • 4) Move back at least 3 feet from the edge of the ring • 5) Catch any bot that is out of the ring and turn it off • 6) Place the bot back in a holding area between matches. A contestant may • make adjustments between matches, but may not leave the holding area. • Basic Rules: • One match will consist of three rounds, within a total of 3 minutes each. • The team who wins two rounds out of three wins the match. • 2) The match will be stopped and a rematch will ensue when it is apparent • that neither bot is making any progress for duration of about 4 seconds (as • determined by the referee). • 3) If a part on the bot comes off that is less than 5 grams, the round will • continue. • 4) A player has 30 seconds to correct a problem between rounds. • 5) The referee has the final decision in a match.
