Human-Powered Strandbeest

TV personality and maker, Adam Savage, sits on a chair attached to a milk crate on wheels. It is situated inside an assortment of steel tubes forming the legs and body of a strandbeest walking machine.

Once you’ve seen a strandbeest, it’s hard to forget the mesmerizing movement of its mechanical limbs. [Adam Savage] built a pedal-powered strandbeest in (more than) one day in full view of the public at the San Francisco Exploratorium.

One of the biggest challenges with building strandbeests is the sheer number of parts required to build a walking machine. It becomes clear rather quickly how big of an advantage the wheel is for part count on a device. Add in a few seemingly small design errors, and you might not have any forward motion at all.

[Savage]’s build takes us through all the ups and downs of this process, including lots of wrenching, welding, and more sneakers than Squitter the Spider could wear. The final product is unwieldy, impractical, and beautiful. What more could a maker ask for?

  1. Fast clicked through an entire 20 minute video for the payoff- very disappointed. Struggle bus to get a couple of very anemic forward steps, and absolutely zero sustained motion, forward or otherwise, and even that required a dude to come out and jack with the drive mechanism. BoooooooUrns.

    1. It’s Adam Savage! Please don’t tell me you don’t find every second of his videos intensely interesting! (My comment if you don’t: Don’t do mechanical engineering)
