is there any kind of actuator that is strong and fast enough to power a giant walker?
I have seen that "Land walker" robot built in japan or somewhere around there. it was really cool, and i bet 90% of people who saw it wanted one.(I did)
But it kind of shuffled about instead of walking about.
Granted it is a big step in that field, i wasn't expecting anything better.
to build a tiny walker is a very difficult task (at least for me, I've got 2 right now that are in a "sick bay", if you will)
There is also the ATHLETE (All Terrain Hex Legged Extra Terrestrial Explorer) robot built by the Jet propulaion lab in NASA. It is about 4 meters wide at the base. It looks kind of like a giant AH3R.
they hope to make a 12 or so meters wide one.
but it technically doesnt walk it has wheels on its feet and its legs act more like a suspension system.
on top of that thig thing is VERY slow.
is there anything that tops these and what kind of actuation do they use?

Hydraulics, Pneumatics, Steppers, Cams run with a V8 gas motor, industrial servos - take your pick.
