FRC 2011 Game - Logomotion

Logomotion is a game in which robots compete with alliances of three teams to hang inner tubes one a rack of pegs on the opposing sides of the field.

Here is a detailed description of the rules (from Wikipedia):

Match periods

A match is 135 seconds long.

• Autonomous - first 15 seconds. Code on the robots is remotely activated, and robots may react to sensor inputs and commands programmed into the robot's onboard control system. The robot tries to score Ubertubes onto pegs on the scoring grid.
• Teleoperated - final 120 seconds. Humans using a console drive their robots around the field, trying to score points using any game piece.
• Endgame - final 10 seconds. Minibots may be deployed onto the towers to score extra points. They may only be deployed during this period.

Alliances

As per previous years' competitions, three teams are on each alliance, red and blue. Each team may have one robot on the field. That robot may be remotely controlled by a driver after the autonomous period.

Field

As per previous years' competitions, the playing field is 27-feet by 54-feet. The floor consists of gray carpet. On each end of the field, there are scoring grids, immediately in front of the alliance stations, where the robots are remotely controlled by drivers. Each alliance station is protected by a wall, known as the alliance wall. On each alliance wall, there are two scoring grids. Each scoring grid has 9 pegs arranged like a square. Each row is 37 inches above the next, except on the outside columns in each grid, where the bottom peg is only 30 inches above the ground. There are openings in the alliance wall, called feeding slots, in every corner, where an alliance member may enter playing pieces into play. However, to get from the scoring grid to your alliance's feeding slot, you must transverse the field. There are towers in the middle of the field, with a cylindrical base. The towers are used in the endgame for alliances to earn up 30 points. To assist teams in driving and programming a robot through almost completely open field, there is colored tape on the floor to allow for sensor calibration and to create visual reference points. Furthermore, the tape delineates area where certain robots may or may not traverse.

Playing pieces

• Ubertube - a yellow, circular inner tube. It may only be used during the autonomous period.
• Minibot - an FTC robot
• The following make up the FIRST Logo.
• Triangle - a red, triangular inner tube
• Circle - a white, circular inner tube
• Square - a blue, square inner tube

Scoring

Here's how the scoring breaks down: during the autonomous period, each ubertube placed on the bottom row earns two points, on the middle row earns four points, and on the top row earns six points.

Here's a table referring to the scoring:

Logo Piece	Alone	Over Ubertube
NOT Hanging	0 Points	0 Points
Hanging on Bottom Row	1 Point	2 Points
Hanging on Middle Row	2 Points	4 Points
Hanging on Top Row	3 Points	6 Points

As for the minibot, the first one to reach the top earns 30 points, the second earns 20 points, the third earns 15 points, and the fourth earns 10 points. The final score is capped at 158 points.

Robots

Robot rules are similar to other years with the exception of the minibot. Notable difference are that while a robot must start the match within 38"x28"x60", it may expand to a 84" diameter cylinder with no height constraints.
