After seeing Theo Jansenโs walking Strandbeest creatures a few years ago, I decided to build my own. Jansen had already done all the hard work of figuring out the linkages that power his PVC contraption, so all I had to do was scale it and assemble it with wood instead of PVC and attach a motor … Or so I thought.
Three years and four โbeest iterations later, I came up with something quite a bit smaller than Jansenโs.
Not only can it walk via remote control and two motors, but it can also observe its environment via a turret-mounted GoPro camera. Because of this, I can drive it in first-person view.
Joachim Haas, whose similar walker was featured in the January 2016 issue of the German edition of Make:, designed a gear train concept that was extremely helpful to building a reliable version.
I call this little one-foot-tall contraption the FPV StrandMaus, or โbeach mouse,โ as a small-stature homage to Jansenโs โbeach beast.โ
The first two โbeests that I built were closer to the size of a golf cart, but due to various issues with weight, friction, and unsuitable motors, they never walked. The third โbeest (and the first that I would call a โmaus) was even smaller than whatโs pictured here, but didnโt feature bearings or the same gear train setup. Though it walked for a limited time, I soon scaled it up to the successful FPV StrandMaus, which I CNCed out of ยผ” MDF.
