A 108-piece hydraulic robot arm that actually moves under water pressure, with four axes of motion and working action levers. Build it, then use it to simulate real satellite retrieval missions with the included astronaut and accessories. The 40-page booklet explains the engineering behind the real Canadarm: and kids get to operate a working version of it on their desk.
The Canadarm Robot Arm puts real space engineering in kids' hands, a NASA-inspired build that assembles into a working hydraulic robot arm.
