For companies with well crafted prototypes, the imagination of adding blunt force trauma to the prototypes is unthinkable. In fact, the reason is because they don’t treasure baseball the same way iRobot does. iRobot added a baseball bat to its 3 fingered prototype when they were working on a mechanical hand for DARPA’s Autonomous Robotic Manipulation program. You don’t have to be scared because the outcome was quite good, intact.
The artificial hand proved to be durable with flexible feelers; fingers molded from soft polymers and embedded tactile sensors. There was nothing like bends on the metallic joints, instead, cheap cables crafted from fishing lines were pulled tight to make the digits. The advantage with these is that they are easy to replace in case one breaks.
With the help of the soft fingers, it is possible to pick up keys, credit cards or other small objects and also hold approximately 50 pounds before slipping up. The hand has an iteration that is being used today on DARPA test robot.
