A few years ago I saw a film brought by a guy from your very institution, 
about a robot sheep shearer. The cutter head "flew" over the animal's body 
using capacitive sensing (the sheep was grounded). It was claimed to work 
well, but perhaps it didn't really perform under realistic conditions.

Optical sensors always appealed to me more anyway.
