I think I get it now.  After going back to the robot model and trying to
recreate some animations I've done before, there appear to be a couple
of bugs...

First thing I noticed is that you really need to select "linear" or
"cubic" before setting the key (and it appears you may need to reselect
for each new key at times).  Otherwise the subobjects of the robot don't
have their interpolation set to linear.

An apparent bug (introduced in the last beta or so) is that if you force
a key (using Set|Object) doesn't properly propagate the
step/linear/cubic down into the subobjects.  this, I believe, is what is
causing your problems.
