Holding a water pistol to shoot at foxes in my garden might be useful. They other humane deterrents (ultrasonics etc) don't work.

You don't really need a robot arm for this though... Also on my list of projects for cats :)

Future proofing for when they evolve into flying foxes! You'll need the extra degrees of freedom
