It was a difficult job. Mr McLoughlin says the device had to have many small motors to have the ability to do what a human hand does. It also need to have human-like strength. The thumb was especially difficult because it permits the hand to hold objects. And everything had to fit into a space about the size of a human hand.这是一项艰难的任务.洛克林先生说,该设备必须有许多小马达,才能具有人手的能力.它还需要近似人类的力量.拇指是尤其困难的,因为拇指让手能抓住东西.同时它必须适合放入人手大小的空间里."
