This Clever Robotic Finger Feels With Light
Robots already have us beat in some ways: They\u2019re stronger, more consistent, and they never demand a lunch break. But when it comes to the senses, machines still struggle mightily. They can\u2019t smell particularly well, or taste (though researchers are making progress on robotic tongues), or feel with their robotic grips\u2014and that\u2019s a serious consideration if we don\u2019t want them crushing our dishes or skulls.
