美商务部国家标准局的研究人员正在研制一种自动激光干涉仪跟踪系统,他们确信这种测量系统将能极大地提高机器人性能测量的精度。这种系统由激光干涉仪、伺服控制反射镜、装在机器人臂腕关节上的伺服控制跟踪反射镜及电子计算机组成。当机器人在其正常工作通道上运动时,该系统能连续测量目标反射镜的位置,包括测量机 Researchers at the US Department of Commerce’s National Bureau of Standards are developing an automatic laser interferometer tracking system that they believe will greatly improve the accuracy of robot performance measurements. The system consists of a laser interferometer, a servo-controlled mirror, a servo-controlled tracking mirror mounted on the wrist of a robot arm and an electronic computer. As the robot moves on its normal working path, the system continuously measures the position of the target mirror, including the measuring machine
