Two silver, cylindrical robots with legs and yellow domes on their heads walk across a tiled platform, carrying a large blue rectangular block between them, while a bearded man in a spacesuit sits on a box in the background observing them. The robots move from left to right, then turn and walk back to the left, carrying the block, in a continuous loop on a platform with rocket ships and a large spacecraft in the background.
