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
