Passage 2        Today’s robots must be precisely programmed to __26__ a car part or even help performsurgeries. But when it comes to__ 27__ an object they have not touched before, such as an egg,they often fail. Now, engineers have come up with a solution to overcome that limitation. ArtificialFingertips like TacTip could enable robots to __28__ objects of all shapes and sizes without suchprogramming.The researchers are optimistic that TacTip will shrink. Cameras and microphones are gettingsmaller all the time, and 3D printing techniques are enabling thinner layers.
       They believe that suchsmaller devices might approximate human “feel” even more because they would be able to __29__ finer textures and thus be more dexterous. This research has explored how the skin’s nerve endings__30__ what they sense to get the fingers to catch a ball slipping through our fingers or pick up anorigami crane without crushing it.
