This is what happens when you lock researchers away for too long

They start to pro­gram their robot vac­u­ums to act like some of the Seven Dwarves, and then see how peo­ple react to them. Really.

Researchers in the lab of OSU assis­tant pro­fes­sor of com­put­er sci­ence Heather Knight equipped a Neato Botvac vac­u­um clean­ing robot with move­ment pat­terns inspired by the per­son­al­i­ties of Happy, Sleepy and Grumpy.

So what happened?

True to form, study par­tic­i­pants rat­ed Grumpy as the least polite and least friend­ly, where­as Happy upheld rep­u­ta­tion by being rat­ed the friend­liest and smartest. Happy and Sleepy were togeth­er deemed most polite, though their rat­ing was just above neutral.
