More StrandMaus Footage

StrandMausAfter my first video attempt, I decided to make another clip, this time featuring the external camera more prominently than the FPV GoPro footage. FPV footage is from my Hero4Session – now known just as “HeroSession” – Amazon.

The results, as previewed in a little GIF above, I think are much better. In the FPV portion, I featured a view of the front legs/linkages prominently, as I think this is the most interesting part of the design, that and the actual camera turret setup. Check out the whole video below!

You can see the original video, as well as a little more information in this post.


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!

StrandMaus Now Fully Walking

After some work with a Dremel tool, my StrandMaus was able to successfully walk without tipping over after a few steps. See below for the proof:

I ended up cutting a fraction of an inch off of each leg. I don’t remember the exact number, but 5/8 of an inch ring a bell. Anyway, I suspect that the problem (as someone suggested) is that the legs are longer than the original Jansen design.

I wasn’t sure how this happened, since I based the linkage design on his numbers. After considering it though, I believe I put the nodes where each linkage was supposed to end where the holes are (as pictured below). I offset the original lines to allow for the holes, leading to a longer final linkage and thus my problems.


Or so I would assume. Check out the second video below for a slideshow of how this ‘Maus was put together:
