It only now occur to me that it's animation we're talking about, not filming. In
that case it does not matter hos long it takes etc. between the shots (sure,
fast is better it don't need to be 30fps fast). Then you could easily build a
mechanic solution, motorized if you wish.
In lack of a rotation sensor you can use the lightsensor, if that's availible to
you, see this by Rob Stehlik:

Looks like Bob Kojima is working on a little something:

If you need to have the camera close to the ground, either elevate the "studio
ground" (or lower the camera tilt/pan under ground level), or hang the camera
under the turntable.
Take a look at the great roller designs out there too (see under Turntables,
specificly the ones by Beat Felber):

| (...) Two reasons. One, using a motor didn't occur to me. ;) Two, I don't have any rotation sensors either. I'm also unsure how I could use a motor to tilt and raise at the same time, though I don't think that's a movement needed very often. I could (...)
