I'm referring to the one on the right.
Do you think that it actually moved? How did the drive get to the rear axle? Then what happens?
Have you seen any other 4 legged machines along similar lines?

KENAT,
Have you reminded yourself of FAQ731-376: Eng-Tips.com Forum Policies recently, or taken a look at posting policies: http://eng-tips.com/market.cfm?
RE: Mechanical horses
No, looks like either a static rig, or (more likely) an "artist's rendering"
"How did the drive get to the rear axle?"
Can't see any drive to rear end. Thus #1 answer above.
"Then what happens?"
It would fall over on the first step?... unless gyro-stabilized? Nowadays it would be controlled by some kinda bit-crunching gizmo to stay up.
"Have you seen any other 4 legged machines along similar lines? "
Yeah, somebody posted a 4-legged "mule" video (with bystanders kicking it and it "trotting" to maintain balance)in ... the automotive? mechanical? forum awhile back. It is apparently the product of a DARPA initiative.
RE: Mechanical horses
The rear links seem less finished than those in the front, suggesting perhaps they were in development. There doesn't seem to be much of a backbone, and what there is, is curved. It _could_ house a flexible shaft, but I don't see an after gearbox. I can't quite see how exactly, but I'm thinking maybe the rear is driven passively, i.e. by being pulled along by the front and rocked from side to side.

RE: Mechanical horses
Yes Mike, my guess was the front legs may have actually managed some sort of walking type motion, though the joints look a bit light for real work.

RE: Mechanical horses
The hill climbing and hill descending modes looked distinctly different too, as did the climbing over the bricks mode.
