Oh my goodness, that's brilliant. My boyfriend is partially deaf and also the heaviest sleeper I've ever met, and oversleeps pretty regularly even with the loudest blaring alarm I've ever heard, a wake-up light, and a vibrating alarm under his pillow. As a relatively light sleeper with normal hearing this combination nearly gives me a heart attack every morning, while he barely rolls over until I hit him enough times to actually wake him up and turn his alarm clock off, but if I'm not there he tends to oversleep a lot. To answer GP's question, some partially deaf people use grumpy significant others as an alarm clock. But I might have to look into a similar robotic setup.
