That is a joy to watch. Even if it is slower than some other gait, it
is very interesting to watch. I have vaguely followed your pneumatic
threads, watching the cool diagrams and devices, but I will admit you
lost me a while back with this. You and mark are clearly the masters
of Lego pneumatics.

I find it pleasing to watch also.  It is very decisive about its stepping.
When
legs are moving individually, they do so realtively quickly, and then they all
move at once, you see a definite lurch in body location.  There is something
about that that makes me just want to watch it walk.

How does it cope with uneven ground? It would be interesting to see a
vid of it pulling itself over rough and bumpy terrain.


If you have four pistons and four switches you can make a biped.  In some ways
bipeds are hard because of the balance thing, but at least in LEGO pneumatics,
they are very simple (very much like a four piston reciprocating engine).

Ah - some kind of chicken walker. The thing that interests me most
about pneumatic walkers is that they are compliant, and their method
of movement may allow them to deal with difficult terrain in a
different way from a servo controlled walker. At some point I would
like to try to put together a walker with forward/reverse as well as
left/right control from a controller playing rider to a pneumatic
walking system that handles most of the walking motion.


Its a pity there is no sound on that video. You may find that some
people with slipstreamed SP1 windows have trouble viewing it - indeo
codec is no longer shipped with windows, and  costs a few bob!

I'm really a neophyte when it comes to this stuff.  Do you have other
suggestions on encoders I should use?

Probably I would say Xvid - it is free, legal and fairly simple - it
should present itself as yet another codec when playing back or when
encoding. The windows binaries are available at http://www.koepi.org/
