Re: Cajun Crawler - Walking Segway

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!

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.
