Introducing the FPV StrandMaus


If you’ve been following this blog for any length of time, you have seen my various iterations of a remote-controlled vehicle based on Theo Jansen’s StrandBeest. My latest version is much smaller, so I’m calling it the “StrandMaus” (Beach Mouse, instead of Beach Beast). Check it out walking around in the video below:

I plan to explain how it works in further detail in another video or post, but what really sets this apart from my other versions is that I’m using thrust bearings from Servocity*, along with shaft collars, which allow the legs to be tightened more than the loose configuration I tried before. Also, the gear train is partially based on something I saw on Twitter from Jo!, using gears instead of linkages to transmit power between the central shaft and the legs.

Probably the most visually obvious feature of the FPV StrandMaus is the GoPro camera (a tiny Hero4 Session – Amazon) attached on a Servocity Pan/Tilt system. I used this on my first StrandBeest model which was neat, but was never able to walk on its own. In theory, one could log onto the StrandMaus’ camera and view it remotely while having it walk around it’s environment. Certainly I’ll have to experiment with this further in the future!

Until then, check out the original StrandMaus below. It’s slower and much smaller, but its gait is somewhat reminiscent of a very slow animal:

*Servocity was nice enough to provide me with some of the mechanical parts for this build.


  1. Very interesting robots. How much time was spent on the design?

  2. Your Strandmaus is a great build. Congratulations! The geometry you chose makes it walking very gracile. The points of the toes are moving very close towards eachother. Keep on making and thank you very much for mentioning my design 🙂
