Line Following Challenge

Rules of the Game:

• One minute will be allowed for setup and calibration before each round.

• The robot must fit within the 18 x 18 cm starting box (no weight limit).

• The maximum number of motors is two.

• The maximum number of line sensors is two.

• The robot must start with its sensors at the beginning of the outer line.

• The team operator is only allowed to place the robot on the board and to push its starting button when told to do so.

• The judge will time the robot.

• If the robot leaves the line it will be given 3 chances (line crossings) to reconnect by itself within one vehicle length (~ 18 cm) of leaving the line. (The judge’s decision on ‘loss-of-line’ is final.)

• Each robot will be given two official trials at the line and the shortest time will be recorded.

• The robot finishing the path in the shortest time will be the winner.

• If two or more robots finish within 2 seconds, or no robots finish a run off will be declared between the best entries.
