Has there been any history of problems with the robotic arms? They're
pretty complicated things, and it just occurred to me that I can't
recall them ever having an issue, and how incredibly essential they
are to operations up there.

Columbus is on the move.... Very cool stuff.

I thought that the station arm (the SSRMS) has had some "field work" done on
it. I believe a wrist joint was replaced during an EVA.

Correct. One of the elbow joints lost one degree of freedom on one of two
channels during STS-110 S0 truss, 4/2002. A replacement joint was installed
during STS-111 UF2, 6/2002.

The control system kept crashing shortly after it arrived at ISS. Bad
hard drives, IIRC.

I seem to recall that a pretty efficient job of finding all the pitfalls
early on occurred, and in that classic bell curve, they are in the almost
flat region now, no doubt when bits start to age we will see how easy, or
not these are to fix.
