Maybe next year we won't be allowed to use any wheels? ;)

From a mechanical standpoint, that's awesome.

But from a real life standpoint, that looks like something the evil villains in a superhero movie would use to get around in.

too late.


By the way, if you are not familiar with the leg designs being used on this device, it is a direct derivation of Theo Jansen's Strandbeest, and the rather unique linkage designs he developed.

Reading the phrases "real life" and "evil villains in a superhero movie" in the same sentence makes me giggle.

I was very curious about how the articulation of the legs was achieved. Now that I've seen the video of the Strandbeest "Animaris Rhinoceros", it is fairly clear. A couple of parallel linkages coupled to a set of reciprocating triangles.

I can only assume that the drive for each "leg" comes from a rotating shaft with cams, or offsets, driving the linkages to the reciprocating triangles.

Fairly close??

Don't say that! Low traction wheels were bad enough this year! :P

That's cool actually. It looks like it has principles of movement we see in insects, yet it looks like the combination of rollers and the multi-legs provide high mobility. As it shows though, speed is an issue, especially when you have too much weight. It would cause easy tipping with a disproportionate weight distribution over the top and the bottom.

I don't know, I think I'd rather high friction legs then low friction wheels. Wish I had time to toy with this a bit myself.

Here is a great 3d model that breaks it down:
