the concept sounds, actually awesome QUICK TO THE PATENT OFFICE!!!

well, there aktually is one artist that did create a rather good mechanic walking cycle,

Theo Jansen

type his name in YouTube,
you will find a lot

Those are just automatons you can't sit on them.

you can not sit on the beasts thats right, but the mechanism is the the vital thing,

as far as you can get the geometry of the mechanism at Janses page it is often used,

for example for tiny walking robts:

(it is hard do see, but they got four sets of three "Jansen Legs"

or for example it is used as a bike:

This looks like the kind of thing Cthulhu would do to keep his tentacles in good shape.

*screams and cries and runs away*

Someone's got to say it.

Wrong number of legs. 83

This, its a insectobike

the rider has two legs.

Then it would be a Spider Human-Bike or something...

Heck, I'd buy one.

It's like the crab car from futurama.

Kjartan's bicycle emporium

We may not be the cheapest, but we've got everything!

Actually... this looks like the old MOTU Spydor vehicle...
I am a nerd...

Yeah I've seen mechanisms that would work that way using a pedaling motion, definitely, it wouldn't look much like the drawing but it could be done. :D

Bonus Multiplier: the Jumping Spider helmet.

I was looking for walking robots, using known actuator designs, and found a patent for a 6 legged walking backhoe from 1997. Noone was intrested, so it was pulled in 1999.

Take 6 backhoe arms and attatch to a frame, put the cabin, engine and controls on top. Get a headache workin on the walking functions.

Id love to see it used for asteroid mining. Fire at the target, let the legs impact, then wait for it to extract itself and start throwing ore into orbit.

Soiderbike, spiderbike, does whatever a spiderbike does. 8)

Wonder how long 'til we see one of these at Burning Man.

But...can't it also walk up walls and on the ceiling?

LOL kool
