We never tire of watching Strandbeests with their multitude of legs walking around, and especially enjoy the RC ones. [Jeremy Cook], prolific Strandbeest maker, just made one by motorizing and adding remote control to a small, plastic wind-powered kit.
We’ve seen a Strandbeest kit conversion like this before, such as this DC motor one but it’s always interesting to see how it can be done differently. In [Jeremy’s], he’s gone with two inexpensive $2.00 stepper motors. The RC is done using a keyfob transmitter with a receiver board wired into an Arduino Nano’s analog pins. He tried driving it directly off the LiPo batteries but had issues which he solved by adding a 5-volt regulator. Check out his build and the modified Strandbeest walking around in the video below.

If you’ve never seen a Strandbeest before, you’re going to want to watch the video after the break. Invented by [Theo Jansen], a Strandbeest is a kinematic work of art. An eight legged structure that walks around under wind power — or if you’re clever, an Arduino and some motors.
For a weekend project, [Remet0n] decided to motorize a toy version of the Strandbeest, and make it remote-controlled. The toy is normally powered by a propeller spun by the wind — making it very easy to replace with motors. You can pick them up for under $10 on eBay.
Using an Arduino Nano, two small 3V motors , a wireless chip (NRF24L01) and a L9110 H-bridge, he was able to create this awesome little remote-controlled device:
