机器人虽然凭借电流控制能“握住”杯子等东西,但人要比它高明得多。以触觉为例,人的指尖能感知只有5微米高的突起,而这个数字仅仅是一根头发丝直径的1/50。至于舌头和嘴唇的敏感度就更高了。当你试着把一根头发放到嘴里时,立刻就会感觉到有一个很大的东西在嘴里,让你感到不舒 Although robots can “hold” cups and other things with current control, people are much smarter than it is. In haptics, for example, human fingertips can sense protrusions as high as 5 microns, and this figure is only 1/50 of the diameter of a hair filament. As for the tongue and lips, the sensitivity is even higher. When you try to put a hair in your mouth, you immediately feel that there is a big thing in your mouth that makes you feel uncomfortable
