The strandbeest is an amazing piece of engineering, a simple walking structure that resembles an an animal as it moves.
This kit is available as an original 'Wind powered' Strandbeest, where a large sail provides the main driving force, or as a motorised, steerable version.
A small electronic kit starts a wifi network using the ESP8266 and two continuous rotation motors to drive the left and right legs independently, this creates a fully steerable vehicle that can be driven directly from your mobile phone or other device.
If you already own one of these strandbeest kits you can purchase the electronics package on it's own which can be fitted onto your own set of legs.
