I guess not being punched is just not good enough for some people, so an Australian structural engineer named Kris Tressider has built himself a robot to fight with. It may be powered by windshield wiper motors, but in no way stops it from flailing about in a threatening manner. See for yourself:
The robot can be adjusted in innumerable different ways, and it's not just repeating the same motions over again: it randomly throws both jabs and hooks at different speeds and from slightly different directions. And there's also this:
"A third electric motor can then be engaged via an opposing cam cable device to become berserk."
An indestructible punching robot with a berserk mode. What, besides a major motion picture, could possibly go wrong?
Kris hopes to turn Punching Pro into an actual product that you can buy and hide in the closet of whoever needs a good old-fashioned throttling; the target price is somewhere just under $1,000.
