Thanks.
Here's a few observations (more or less "from what I can see...")
- The compressor (on top) uses 12 small cylinders
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=551846
- It has 2 battery boxes
- The legs lock, and are driven up & down by pneumatics, one cylinder to raise/lower
and another to lock.
- Up: http://www.brickshelf.com/cgi-bin/gallery.cgi?i=551845
- Down: http://www.brickshelf.com/cgi-bin/gallery.cgi?i=551844
- The legs are driven forward/backward by motors->znap
flex-axles/u-joints->wormgear->turntables
- The leg pneumatics are driven from cams, which run off the main motors. So the
forward/back motion would be sync-ed with the up/down via cams. Springs are used to
keep the switches against the cams
http://www.brickshelf.com/cgi-bin/gallery.cgi?i=551860
- Each leg is only connected to 2 pneumatic hoses
- The feet swivel
- From some pictures, it doesn't look like the legs are connected directly together:

- But they are: http://www.brickshelf.com/cgi-bin/gallery.cgi?i=551858
- Transmission type shifting is used for forward/back leg motion (see above)
- The Claw is only decorative http://www.brickshelf.com/cgi-bin/gallery.cgi?i=551840
:)
- There is no "controller"
Comments:
This is a nice piece, but, personally, I'm not too fond of using the transmission to
shift the direction of leg movement, or for that matter, the whole worm->turntable
assembly.
Don't get me wrong, I'd love to see it walk, and it's better than any walker I've
ever made... but then again, I've never made a walker...

| (...) There does not seem to be any guaranteed synchronization between the up down mechanism and the forward back. Slow pistons might not hit the ground before the front back transistions start. (...) That is nice and tidy. (...) Yes, I have a (...) (20 years ago, 18-Jan-05, to lugnet.technic)
