joint. The femur/tibia joint stays pretty straight when the foot is down so
it's equivalent to the leg of a "standard quadruped robot" except that it's
H-plan rather than X-plan. That's totally unlike the "robot" shown in the
Beta costume version.
Aha, I think I may see why we have such differt perspectives.
I'm referring, of course, to last year's model (the latest, I think) as
shown in the 17 Mar 2008 video
The older model from a year before _was_ like the Beta costume version, see
the 20 Apr 2007 video
The old model certainly had a "mammalian" stance. I agree with all of your
arguments about Old Big Dog. But for New Big Dog, the designers have decided
that an H-plan "lizard" stance is superior.
