I'm wondering what is the technical term for measuring of human gaits - like the
timing, distance of swinging a leg, angle of
rotation of joints, etc., for legged robots. Is there a database of this sort
of thing taken from live animals and people ?
Thanks !

Start by looking for biometrics (old, non-id-meaning), gait analysis,
or motion capture.
From a search for "gait database":
http://www.univie.ac.at/cga/data/index.html
http://www.sinobiometrics.com/english/Gait%20Databases.asp
http://www.cc.gatech.edu/cpl/projects/hid/
From a search for "motion capture database":
http://mocap.cs.cmu.edu/
Somewhere I have 30s snippets of 100Hz motion capture data for several
people walking on a treadmill. These contain XYZ position data for
roughly 23 body markers. But many markers contained glitching due to
obscuration, etc. -- the CMU data looks better.

Thanks! Exactly what I am looking for!
Thanks again !

Did you ever do anything with the CImg library
back in June 2006?
I assume from this post you intend to build a
four legged walking machine?

Hello again, John! Nah ... I never really did much with the CImg library. I got
sidetracked with building my website and designing
the robotics platform to sell on it. I can't help but think that sometime soon
(in the next 5 years I would hope) that useful
image processing will be affordable for the hobbyist. ( The Evolution Robotics
vision software is now running on embedded
machines, so it seems like something ought to be available to us tinkerers
relatively soon. )
As for building a walking machine, I would prefer to build a 2-legged one
(humanoid). I'd really like to see a child-sized
humanoid platform - maybe 3 feet tall - that would be "affordable" ($5-10,000 or
less, if you call that affordable) But a four
legged one could be just as useful, I suppose.
Shameless, but infrequent, plug for my site: http://www.amazingrobotics.com
