Imagine if you were a snake and could evaluate your surroundings by feeling vibrations in the ground. Because of recent technologies, people have developed artificial sensors that equal or even surpass the senses of animals. "Robot hands" equipped with touch sensors help humans investigate dangerous or inaccessible areas, like outer space and underwater. Researchers are developing a robotic hand that can spell out the letters of words on the palm of a deaf and blind person to communicate over a telephone line. Virtual reality is used in medical training so surgeons can practice delicate procedures. Learn more about these new discoveries and what they mean for the people who can benefit from them!
