Strandbeest Powered by Compressed-air Engine

Strandbeest is one of leg mechanisms which simulate the gait of legged animal. It was created by Theo Jansen in 1990. This model has six-pair of legs with 90 degree phase differences and the minimum crank radius of one module in LEGO Units.

This model was powered by a compressed-air engine. The engine converts the compressed-air energy to mechanical work by the combination of piston actuators and air switches. The compressed-air was stored by two air tanks. Therefore, the engine can be separated from an air compressor.

The smooth movements of link mechanisms and compressed-air engine were shown on the video.
