Game

· 2 minute rounds

· Minimum of 2 rounds per robot.

· There will be a seeding round to determine competition bracket.

· The robot with the most points wins.

· Teams may clean or dust the arena with a dry rag (provided by the officials) at the beginning of the round.

· It is difficult to distinguish intentional aggression from bad programming, so both will be allowed.

· Teams may turn off their robots at anytime but they must remain off for the remainder of the round

Arena

· 8’x8’ masonite base

o Composed of 4 pieces, each 4’x4’

§ Will make transportation easier

§ Since we have to have seams somewhere, this guarantees both teams have to deal with the same amount of seam

o Supported by a wooden frame so it sits a few inches off the floor

· 3/4"lines will be painted on the base in contrasting color

o The track will be centered, leaving 1’ of clearance to the wall

o Each square of the grid will be 18” on its side

o The curves will be half-circles of radius 9”

o Both of the tracks will extend 9” past the last intersection at the start and end

· 1½” wall around the perimeter of the base

o Prevents aggressive robots from knocking their opponents out of the ring

o Will have a 1” strip of retro reflective tape on the top of the wall

Tokens

· Both metal and wood tokens will be present on the board.

o Each wood token will have metal one resting on top of it so the pair can be collected in one motion OR just the metal one can be collected

· Wood

o Worth 2 points each

o 16 total – one located at each intersection

o 1” diameter cylinders; 3/8” high

§ Most line following sensors should be able to pass over it

o Mechanically challenging to collect

o The bottom sides will be beveled to assist in mechanical collection

· Metal (steel)

o Worth 3 points each

o 22 total

§ One resting on each wood token (16)

§ One located at the top of each arc (6)

o 1” diameter circles; nearly flat

o Easy to collect magnetically; very stackable

· At the end of each round robots will be removed from ring by competitors and placed in area designated for scoring. Tokens that remain with robots after being removed from ring will be counted towards point total. Tokens that fall off of bot during removal will not count towards final total.

Robot

· Size limit 12” x 12” base (no height limit)

· Only 2 drive motors allowed – must be provided Faulhabers

· Weight limit: none

o This should be sufficiently constrained by the drive motors.

· Only one magnet allowed per robot (either electromagnet or permanent magnet is fine)

o The magnetized collection surface may be no larger than 2”x1”

· Robots must not actively interfere with the sensors of other robots

· Robots must not damage or deface the arena

· Robots must not lift other robots

· No projectiles, weapons, hooks, sticky exterior, liquids, etc. No weird offensive stuff.

Referees

There will be two volunteer referees observing and timing each round. The volunteers may be participants in DC, but may not be involved with either of the competing robots.
