Zombie Robot Cockroaches. Link (with picture).

"A research team at Tokyo University is making these bio-bots by lopping off the antennae of regular roaches and replacing them with pulse-emitting electrodes. The researchers then send signals with a remote control to a backpack worn by the roach that powers the electrodes. The roaches can be told to go left, right, forward and back, and the team sees all sorts of "betterment of humanity" applications such as outfitting the bugs with mini-cameras to take on the good old search and rescue, or for a bit of espionage."
