R/C Rocket-Beest Burns Up Fuses Out There Alone

We’re beginning to think the “S” in [Jeremy S Cook] stands for strandbeest. He’ll be the talk of the 4th of July picnic once he brings out his latest build—a weaponized, remote-controlled strandbeest that shoots bottle rockets. There are a bank of money shots up on Imgur.

This ‘beest is the natural next step after his remote-controlled walker, which we featured a month or so ago. Like that one, the locomotion comes from a pair of micro gear motors that are controlled by an Arduino Nano over Bluetooth. The pyrotechnics begin when nitinol wire cleverly strung across two lever nuts is triggered. All the electronics are housed inside a 3D-printed box that [Jeremy] designed to sit in the middle of the legs. We love the face plate he added later in the build, because those gumdrop LED eyes are sweet.

Can you believe that this vehicle of destruction began as a pile of innocent, pasta-colored pieces of kit? We dig the camouflaged battleship paint job, ’cause it really toughens up the whole aesthetic. And really, that’s probably what you want if you’re driving around a spindly beast that can just shoot rockets whenever. Let’s light this candle after the break, shall we?

Jeremy Cook's strandbeest kit RC conversion

Stepper Motor And Key Fob Controlled Strandbeest

May 12, 2018 by 7 Comments

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.

Motorized Strandbeest Is Remote Controlled And Awesome

February 3, 2016 by 20 Comments

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:
