Thanks Tom,

OK, On closer inspection (opening the chassis) I found the wiring harness
is intact.  I thought these were wired on the outside of the chassis.

The shoulder looks to be fine, it is just the wrist that is broken.  Looks
like it was a cheap plastic part that wouldn't take much to break.  Maybe
I will fabricate one out of something stronger.  Any ideas where I could
get drawings for what the part looked like before breaking?

The batteries are not there, nor did it come with a charger (or training
pendant).  I figured some off the shelf lead acid batteries would fit.  I
have read where people replaced the 4 6V batteries with 2 12V ones to
lower the center of gravity as well.  I don't know which battery leads go
to positive or negative, so won't plug in anything just yet.

As for the standard robot libraries, have you looked at ROS (Robot
Operating System)?
