There's people working on better robotics, trying to make them as good as human motor movement, but they haven't yet succeeded. Putting robotics in
space is definitely possible; look up the Canadarm, for an example. The trickiest part of designing a good robotic hand, from what I've seen, seems
to be building it such that all of the 'degrees of freedom' are as good as a real, human hand. (there are six degrees of freedom, representing
moving left, right, up down, etc)
This one looks pretty cool, for example: en.wikipedia.org...
It is depicted holding a lightbulb with its fingers.
I don't see any particular difficulty in transferring the technology into space, beyond the obvious difficulty of actually getting it up there in the
first place. In some ways, it might actually be easier, because you wouldn't have to deal with things like air resistance, dust, moisture, and so
on. However, in other ways it would be much tougher; if the device needed maintenance, for instance, you'd need an astronaut to fix it, so you would
have to make sure the device could operate for a very long time without maintenance.
