Mechanical Engineering Robotic Arms sharks this lifelike stuffed penguin isBuild six mechanical models of the types of arms, grabber claws, and legs found on robotic machines. Explore mechanical engineering principles firsthand as you assemble and play with these working models. The models use a pneumatic system which uses air pressure to activate the models. Pump up the air reservoir with the hand pump, then flick the switch to operate the model: A pneumatic piston enables the grabber claws to open and close rapidly and to
