The most important feather in this design is that the number of motors have controlled only in two and de - scend the motors on the base . ( one motor used for turn motion of the base , whereby maked the manipulator motion in throughout space . another motor used to drive the manus ) excepted for adopped synchronization bell which have light weight and accu - rate gear ratio to reliefed relatively the weight of manipulator ' s device 在本设计中除了采用材质轻而又传动比准确的同步带传动可以相对减轻手臂传动机构的重量之外，最主要的特点足将电机数量控制在两台(一台用于底座的回转运动，从而实现机械手在整个空间的运动；另一台用于驱动手臂的运动)并将电机下置于底座。
