SUMO WRESTLING

During the past 10 years, this event has slowly spread across the world, and now has become one of the most popular robotics contests ever created.

This event aims to explore your creativity against another bot in a field of combat where brute strength and cat-like reflexes hold the key to success. The challenge is to create a robot whose sole purpose is to push, throw, flip, drag, or otherwise move your opponent out of a circular ring within three minutes. This competition is the most popular of the events, both to watch and to participate in!

The Arena: A playfield of 120cm diameter (cut from plywood) with a 1.5cm white line around the field.

Specifications: The specifications of the bot are

· The bot can be autonomous or manual controlled.

· Maximum dimension 15 x 15 cm. No restriction on height.

· Maximum weight 2.5 Kg (for the manual control bot it excludes the controls or the wires.)

· A design that incorporates the stretching the bot’s body or a part is allowed.

· Remote controls will be provided by us so as to prevent any frequency mismatch.

See the pictures for more details. The size of the receiver is 9x12 cm. It’s a 5 way control. (The bot should have enough space to accommodate the receiver)

· Participants are allowed to bring their own remote control but if there is a frequency match then they have to use the remote provided by us.

· No AC supply will be given. The maximum DC supply you can use is 12V. If you battery dries up during the match, it cannot be replaced.

· You should have enough batteries or chargers as the bot might have to play up to 7 matches.

· The bot should not contain any sucking device or glue to stick the bot on to the base.

· The bot should not have pointed edges.

· The bot is not allowed to throw anything at the opponent.(e.g.- fire, solid, powder or some liquid)

The Gaming Rules:

· The bots start at a distance of 15 cm from the centre of the arena facing opposite to each other.

· There will be one to one competition between bots. It case the number of participants crosses the 40 mark then there shall be a Royal Rumble (At least 3 bots will be placed in the arena and the bot that is thrown out will be eliminated and thus the last bot standing in the arena wins).

· Each round will be of 3 minutes, but the semifinal and the final shall be for 5 minutes. Winner of each round progresses to the next round.

· The bot with more points at the end of 3 minutes or the first bot to score 5 points, wins.

· Even if a bot flips it cannot be placed on its wheel, in that case the opponent has a chance to throw it out of the arena.

· In the event of a bot going out of the arena; both will start from initial starting position.

· The round will restart when the bots get locked in a position for more than 30 seconds without motion.

Registration:

All the participants are requested to register themselves before 30^th September 2005, once the registration begins on the shaastra home page. You also need to submit the partlist of the bot

Points:

One point will be given when

· The bot legally forces the body of the opponent’s bot to touch the space outside the arena (i.e. the white line). Partial touches will not fetch points.

· The opponent’s bot has touched the space outside the arena on its own( again the whole body has to touch to get the point)

· The bot flips the opponent’s bot, on its back or side, and thus causing it to be stationary.

In case of a tie, at the end of 3 minutes, the judges can award additional point on the basis of-

· Design of the bot (The movement and operation will be considered).

· Effort by the bot.

· Penalty points during the match.

Penalty points:

· Use of unfair means during the match will lead to immediate disqualification.

· Intentionally trying to damage opponent’s part e.g. motor, wires etc. will lead to disqualification.

In all cases the decision of the judges will be final.

Other rules, which will not dictate the design criteria, will be declared on the day of the competition.

**There can be some changes of which you would be intimated. This is just a preliminary towards what you would face in SHAASTRA. In any case decision of the Coordinators would be final.
