Gap Crossing - Cube Gathering

Pick any subset (or the whole thing!) of the third event from the 8th Workshop 3D RCX Challenge.

Build a robot to collect objects and bring them across a gap. Robots will start at the back end of one table and need to cross over to a second table which is 2-inches away from the first one, to retrieve objects, bringing them back, one at a time, to the first table. This means one block must be deposited in the finishing box before picking up the next block.

The tables will have a light surface with 3/4” matte-black tape lines on them as in the above diagram. The objects will initially be in the 6” x 20” box on the far table, and must be deposited in the finishing box on the first table to count. Robots should not wander out of their 20-inch wide ‘lane’. This is the space that goes from their starting box to the finishing box. Adjacent lanes will only have a narrow separation between them, and lanes may be very near the sides of the table. The length of a lane (width of the tables) is not specified, but will be on the order of a few feet.

The objects to be collected are Lego cubes. They consist of six 2x4 bricks, stacked together, and topped by 4 smooth tiles. They will be white. There will be at least ten cubes scattered randomly in the starting box, clustered towards its center.

The initial maximum size of a robot is 12-inches wide by 16-inches long. There is no height restriction. Robots may unfold themselves, but must do this on their own.
