Popeye the Crab Ages: 15-18
This giant walking crab was built by the imagination of resident LEGO genius Carter. Using pneumatics, the crab walks with two 3-point movements (front and back leg of one side with the middle leg of the opposite side). A series of 4 motors perpetually pressurizes 3 air tanks supply the power. A motorized switching system on the back of the crab automates the movement of the crab.
