Lego pneumatics is a variety of Lego bricks which utilise air pressure and specialised components to perform various actions utilising the principles of pneumatics. Lego Group logo The classic red 2x4 Lego brick. ...
Pneumatics, from the Greek πνευματικός (pneumatikos, coming from the wind) is the use of pressurized gases to do work in science and technology. ...

History The Lego pneumatics components were first introduced as part of the Lego Technic range in 1984. Since their introduction, Lego pneumatics have featured in a variety of Lego Technic and Lego Educational (DACTA) products. Tractor made using Lego Technic components. ...
Lego pneumatics components The key components of Lego pneumatics are: - Pneumatic pump
- Pneumatic cylinder
- Pneumatic switch
- Pneumatic tubing
- Air tank (As of 2006, Lego has discontinued this piece)
- Pneumatic distribution block (also discontinued)
Pneumatic principles Lego pneumatics offer the opportunity to learn and experiment with the principles of pneumatics and control circuits. Advanced use of Lego pneumatics has been made in various Lego Mindstorms creations. Lego Mindstorms is a line of Lego Group products combining programmable bricks with electric motors, sensors, Lego bricks, and Lego Technic pieces (such as gears, axles, beams, and pneumatic parts) to build robots and other automated or interactive systems. ...
Lego pneumatic projects usually include a compressor made from a combination of a lego electic motor and pneumatic pump, together with a pressure switch which will activate the motor when greater pressure is required.
Because a slight delay is involved between increased pressure and cylinder movement, various feedback loops can be used whereby one pneumatic component can activate another in a series of mechanical events.
Lego pneumatics can be configured in such a way that electonic circuits can be replicated. These circuits can then be combined to create digital computers.
Alternative pneumatic systems Fischertechnik offers a similar pneumatics system for robotic and control technology hobbyists. The Fischertechnik system includes and electrically activated air solenoid, a feature not available in the Lego range. fischertechnik® (the lowercase is deliberately used in the trademarked name) is a brand of construction toy. ...
A number of hobbyists have also constructed additional components such as larger air tanks and solenoids to complement the standard Lego pneumatic components.
