Robots are helpful because they can be programmed with standardized motions. A patient who comes in for a physical therapy session can dive right in and do the exercises with the robot for half an hour. And, unlike a human physical therapist, the robot never gets bored with the repetitiveness of the routine.
機器人的好處是，可以將復健的標準化動作程式化，病患一來，就可以自動操作半小時，而且永遠和緩平穩，不會出現職業疲勞。
