In a abstraction for IEEE ICRA 2010, Haddadin, forth with Alin Albu-Schaffer and Gerd Hirzinger, able a apprentice arm with assorted aciculate instruments, such as knives, a scalpel, and a screwdriver, to see what would appear if a apprentice accidentally addled someone.
The advisers had a DLR Lightweight Apprentice III strike, stab, and allotment a leg of ham, a block of silicone, and assuredly Haddadin's arm. Not alone were they analytical about what furnishings the apprentice would have, they capital to analysis a blow abstention arrangement advised to abbreviate the accident of abrasion by robot.
Without the blow abstention system, the kitchen knife artlessly went appropriate into the slab of pork. But with the arrangement activated, it alone penetrated the pig by about 1 millimeter. Haddadin's arm was unscathed. Thankfully, it wasn't subjected to testing with the "safety" off.
The arrangement makes use of torque and position sensors amid in the robot's seven joints, and it does not crave added sensors. The abstraction was the aboriginal of its kind, and it showed that tissue injuries from robots wielding aciculate altar can be minimized or prevented completely.
There's no chat yet on whether Haddadin and his colleagues are activity to commercialize an automated arm for acid veggies in the kitchen. A apprentice Slap Chop? What would Vince Offer say?
