Design Brief- Sumo Car Wrestling


Sumo Car Wrestling pits your robotic creation against another robot in a field of combat where brute strength and cat-like reflexes combine to create the ultimate battle!
Your challenge is to design and create a robot whose sole purpose is to push, throw, flip, drag, or otherwise move your opponent over the edge of a 6 foot square table within 3 minutes time.
The cars are operated by a "video game-like controller" connected to 2 or more 9 volt electric motors. Your design cannot have sharp metal points or other dangerous parts.

THE COMPETITIONThe robots are placed behind the "Shikiri" lines. When both contestants are ready, the referee will signal the start of the 3 minute match at which time the robots may begin moving. The robots will "wrestle" until one unit is disabled or removed from the ring/table.
RULES
Each round will consist of three matches- lasting up to 3 minutes in duration. The winner will be the sumo car which wins two out of the three matches.
In the case of a draw, the referee will decide the winner based on match performance.
A team can call 1 timeout per round. A timeout can only be called when both cars are stopped and not moving. A timeout lasts no longer than 2 minutes.
Cars may be repaired between matches, up to 2 minutes time will be allowed.
A disabled car loses the match.
A car loses the match when any part of it is pushed out of the ring.
A referee timeout can be called at any time.
Specifications
Your car can be any size or shape.
Your car can have as many wheels as you wish. The car must be driven by 2 of "my" motors.
You may use up to 3- 9volt DC electric motors.
You may use the power from the motors in any way to make your wheels turn (gears, pulleys, direct-drive)
The sharpest "pointy thing" that can be added to your car is a golf tee.
Screws, nails, razor blades, knives, flames, paint-balls and/or other items that are deemed dangerous are not allowed to stick out of your car.
Golf ball throwing catapults are allowed.
Your car can be made of any available material, but must be powered by the motors given to you.

Create a folder in My Documents, 7_sumo_yourteamname
Sketch a "working drawing" of your design. Include a top view, a sideview, and a list of materials needed. Show measurement.
Go over your working Drawing with Mr. G. Make changes and go back to the drawing board. Re-do the working drawing. Pass it in for grading.
Start acquiring materials. Cut your basic chassis from available wood. Pick out some Pulley Wheels. Label your parts with your team name and class.
Read and understand the Sumo Wheel Problem Research Project. Assign team members to solve the problem sections. Be aware that this is worth 2 quiz grades, and due before March 3.
Attach your wheels and motors. Block your motors, or they will fall off when they heat up in battle.Solder appropriate wires to the terminal bar. Test drive with a battery.
Test Drive your vehicle, modify if necessary. Select the best driver and assistant.
Build your SUMO Web Page This must be worked on every day to stay current with the Design Process Step you are working on.
Produce an 8 1/2 x 11 "Brag Sheet" on your Sumo Wrestling Car. Insert a digital picture of your design and a team picture, with a page border, Explain the following: drive system, good points, bad points, give the car a name, add your website's URL. Use Microsoft Word, 1 page. Be creative, colorful and neat. Poster is needed to compete. Pass in by March 29/30.
Compete in Sumo Car Wrestling Challenge. Web needs to be complete.
