The Pneumatic Robotic Arm kit is all about advanced robotic movements powered by pneumatic compressed air. Robotic movements are awesome and to play and learn about how these functions for real is so cool. This set has a strong air pump to build up air pressure in the integrated air tank. Once you have pumped up the air pressure inside the tank, you have a reservoir of air you can use for several air-piston movements. With the pneumatic on/off switch, the air is lead into the air-piston that moves very powerfully in the direction it is being directed from the air valve switch. A set of realistic claw concepts makes it possible to build many different claw configurations. A two-finger parallelogram claw gives a very precise and smooth grip on even small objects. The three-finger claw can grab soft and difficult objects like a ball, etc. The robotic lab arm gives you a very direct and maneuverable handling that makes it possible to pick up objects very controlled. The very long two-finger pinch robotic arm makes it possible to reach and pick up objects that are hard to get using your own arm and fingers. The vertical robotic arm reminds you a bit of the classic amusement park three-claw robot.
