UPDATE! Robot found. Well, pieces of robot anyway. I haven't seen what is left of it. I got a call from the police this afternoon that they had spotted it (it is great to live in a small town!) but the guy wouldn't open his door.
So I dispatched a couple of mentors with a truck to accompany the officer to pick it up. Apparently it had been stripped, but they gathered up what they could.
The poor robot had quite an adventure, I'm sure!
