The pick-and-place mechanism is one of them. Pick-and-place mechanisms are used at the high speed, the high repeatability and high accuracy process. Thus, their properties are very important. In this paper, a simple measurement system for pick-and-place mechanisms is presented. It is an optic non-contact measurement system and is characterized by the easy set up, the two-degrees-of-freedom measuring, high sampling frequency, dynamic measuring and the low cost. The experiment results demonstrate the properties of this measurement system.High sampling frequenciesHigh SpeedLow costsMeasurement systemNon-contact measurement systemsPick-and-place mechanismRobot armsIndustrial robotsManufactureRobotic armsMeasurementsconference paper2-s2.0-84883385875
