“Predicting Performance Times of Robot Systems”
sets of element tables for given robot designs
computational performance models for given robot designs
The task input to the RTM analyser is the RTM specification of work method for a given industrial robot, whilst the output is the performance prediction for the specified method. Reference 2 uses a linear regression equation to predict elemental RTM times as a function of the distance travelled during a specific motion. However, the reference also indicates that there is a surprisingly large variation about the mean trend line when measurements are made on the Stanford Arm. It is also possible to show that the approach can lead to large prediction errors when the robot motion pattern contains a number of small segments(3).
