Walking Robot Chassis

Teo Jansen's walking linkage

Jansen Walking Linkage

This is a project to build an 8-legged walking chassis inspired by the walking linkage used on Teo Jansen’s Straandbeest.  The linkage has been re-optimized for the 8-legged design, where the legs are driven at a phase angle of 180 degrees instead of Mr. Jansen’s 120 degrees.  This allows the legs to be driven from a common crank mechanism, such as a bicycle crank, instead of the 3-part crankshaft used in Jansen’s Straandbeests.  This configuration will not be quite as smooth as a Straandbeest, but it will be significantly easier to construct, and is more than smooth enough for motorized operation.  The step was widened and flattened for stability for use with a vehicle operating on a smooth surface.

Here is a video of the first working prototype, created on the RepRap 3D printer at Quelab

Ask Mr.What for access to the SVN repository.  At this time it can be accessed from svn+ssh://boim.com/home/mrwhat/svn/Walker but the URL might change as the project becomes more public.  At this time, you may need an SVN account to update the repository.
