A typical robot can, of course make a positional error exceeding that and that could be a problem for the process. Repeatability is then quantified using the standard deviation of those samples in all three dimensions. Typically a robot is sent to a taught position a number of times and the error is measured at each return to the position after visiting 4 other positions. ISO 9283 sets out a method whereby both accuracy and repeatability can be measured. Repeatability is usually the most important criterion for a robot and is similar to the concept of 'precision' in measurement-see accuracy and precision. Robotics, Automation, Software, Programming, Algorithm,Īccuracy and repeatability are different measures.
