View Full Version : Re: Asimo robot gait

Hello all,

I'll take a stab at this one:

Not knowing what they used for robot "muscles", I would guess the amount of knee flexion observed during the robots gait allows better control of the knee joint. Much like we're finding with ACL tears in athletes, a more extended knee position probably shortens the muscle moment arm and decreases muscular control of the joint - thus they keep the knees somewhat flexed?

Interested what others think.

G'day all,

This question is really just an excuse to be the first BIOMCH-L youtube
reference :-)


I saw the Asimo robot up close today here in Brisbane. It is impressive, but
what interested me was the way it walks with flexed knees. When running the
degree of knee flexion increases further. I am wondering if anyone knows why
the Honda engineers did that - since the objective is to be as humanoid as
possible, the flexed knee must clearly be such an advantage that they
couldn't avoid it.

Look forward to the discussion!
