By connecting an electronic backpack to the legs and antennae of Madagascar hissing cockroaches, researchers were able to control their movements and routes almost flawlessly. Cockroaches can go for great lengths of time without food so they are the perfect biological device. They are also dramatically cheaper than creating a mass of tiny robots.
Applications for these remote control buggers include search and rescue missions, navigating through tight spaces, detecting high radiation levels (cockroaches are highly resistant to radiation), and playing excellent pranks on unsuspecting victims.
Scientists are also developing remote controlled rats and moths. Not a single critter is to be trusted in this brave new world!
