That is quite a problem you have there. The immortal question to follow the
easy road, or plow through the boulders (legos in this case) and set the way
for those that follow. I myself, not at all new to this exact problem, have
little advice concerning 4 foot tall bipedal mecha, but I know some tricks
to scale-down the big stuff.
Try using the rubber-band and small motor method. You can use multiple bands
for a single motor making a sort of transmision in the center of the hand.
Then, set up the bands on each finger using the small half-stud axel rings,
or, the larger one with six holes, the kind you can find with tires.
just like this:
finger finger finger finger
] ] ] ]
(0) (0) (0) (0)
] ] ] ]
(0) (0) (0) (0)
] ] ] ] (0)=r-band joint
-(0)-----(0)-----(0)-----(0)-O O =gear
O-----------O

Sorry, the sketch is kinda rough, but it's not that bad. Just e-mail me if
you have any quiestions.
Hope that this helps.
string also works, but nots well.
