(s.d.)

Why is this?  I have heard this as well.  Is there problems with
scaling down hydraulic technology, and keeping the cost competitive?

By the way, what is your perception of small?  Cat sized, mouse
sized, roach sized, flea sized?

To the original poster: why not use pneumatic cylinders filled with
oil?  Is cheap and quiet.  Just a thought.
