Design and construct one of the two self-contained robots, which can collaboratively carry a long object (a plank) through an open-top labyrinth.

The “plank” is too long to turn around the corners of the labyrinth but labyrinth top is open and walls are low enough so that the “plank” can be passed over the walls.

The labyrinth streets are 25 cm. wide.

The labyrinth size is 5 streets by 5 streets, with one entrance and one exit.

Labyrinth pattern is arbitrary and unknown to the robots before the game.

No overhead cameras are allowed to view the labyrinth configuration.

Direct communication between the robots is not allowed.

The “plank” is a long object of proper(*) size and material, with two holes near the ends. Holes are 40 centimeters apart and are to be used as “holding points”

Each robot will hold the plank at one of the holding points, through a “holder” placed at the center of the robot.

No sensors are allowed to be mounted on the “plank”.

Teams may agree upon a certain maze-solving algorithm.

Possible extra features

Satisfactory performance for longer planks.

(*) Common standards to be satisfied to make cooperation possible, such as the size and properties of the plank, holder/holding point properties, height of the labyrinth walls, etc. are to be decided upon by a joint standards committee, composed of representatives of teams undertaking the project.
