complete as opposed to what the technology is actually capable of. If you
want a humanoid that is a good approximation of all the human gaits, for
instance, you'll have to conquer the problem of dynamic stability. I'm sure
that it's possible to interface accelerometers to BEAM to do that, though I
haven't seen it done anywhere. Once you get past that obstacle, and I
certianly think it's possible, you still have to build a system to control
many different motors. All in all I'd say it's just a problem of degrees.
If you define possible as 'I can design and build it in 12 hours' I'd say a
humanoid isn't possible. If, however, you were willing to spend a number of
months (or years) and build it one step at a time I don't see any reason to
think that it wasn't possible.

Transformers(TM) this year. WowWee, on the other hand, has a "coming soon"
for something that looks like vaguely a typical toy-manufacturer-least-cost
version of the neat thing referenced in the AllNerdReview page. Makes you
wonder what the prototype BIOBugs looked like.
In any case, the pendulum bit -

JPL that designed the thing, not "NASA".

understanding is incomplete. However, I would venture that the
technology is significantly older than many people think.
In "Living Machines" , Tilden references "Passive Dynamic Walking"
 at the second to last page. This was some fascinating work done
by McGeer (sorry, no link). Appropriately enough, you can trace
McGreer's work back to two toy patents [3,4].
Given that Tilden's humanoid walker has been in the past 10 or so
years, and given that Lego's originally came out in 1949, and given
that the patents go back to 1912 and 1888, I think that we can safely
establish prior art.

I have not been able to bring up the Wowwee page since you posted
(router down in Ottawa).
At the time, I did not connect it with the RoboSapien. I had two
reasons for this. First, in my mind it did not bear much physical
resemblance. Second, Wowwee listed the Ape under remote controlled
toys. Electronically, I would think that is different from the
BioBugs with their "Bicore on a blob."
On the other hand, I have been unable to find any information out
about the "RoboSapien" outside of the AllNerdReview article. I would
not be surprised if Wowwee stripped the toy down and repackaged it.

That Wowee ape looks like it walks on slightly different principles. The closest robot I know of is the 'Meka Toro'. The site had a good description of how it worked, but it seems to be gone. Maybe the Internet Archive has a copy. Failing that, I included a picture of it. Basically, it wobbles from side to side, using the wobble to pick up the legs for the return stroke. Pretty fast, too. http://t4l.freeservers.com/MEKATORO.HTM -Martin THE resource for beginners http://beamlinks.botic.com http://beamlinks.solarbotics.net "The best of everyone's BEAM" ------------------------ Yahoo!

"The best of everyone's BEAM"
- Total Robots is selling a bipedal robot kit. I ran across the Total
Robots web site looking for a Solarbotics UK distributor, and noticed
the Sted-E-Man kit. The price is £285 GBP; which is $473 USD, or
$635 CDN. Here is the link:
Total Robots > Sted-E-Man
There are a few videos, and it looks to me like Sted-E-Man builds off
of the "Bigfoot" concept. Would it be possible to build something
along these lines with a servocore?
