Accuracy

Meaning in robotics & automation, with examples

/ˈækjərəsi/nounCommon term

In robotics & automation, accuracy means: How close a robot gets to a commanded position that was not taught on the robot, for example a point calculated from a CAD model. Also called absolute accuracy.

In Turkish: doğruluk, hassasiyet, konumlama doğruluğu

How it is used

Important for offline programming, measuring and machining with robots. Engineers improve accuracy with calibration, better TCP data and compensation software. In specifications, keep accuracy and repeatability separate.

Example sentences

  1. Offline programs need good accuracy; otherwise every point has to be touched up on the real robot.

  2. After the calibration, the robot's absolute accuracy improved from 1 mm to 0.3 mm.

Common collocations

  • absolute accuracy
  • positioning accuracy
  • improve accuracy
  • accuracy and repeatability
  • repeatabilityHow closely a robot returns to the same taught point again and again. Data sheets give it as a small value, for example ±0.03 mm.
  • calibrateTo adjust or measure a robot, sensor or instrument against a known reference so that its readings or positions are correct.
  • offline programmingWriting and testing robot programs on a computer using a 3D simulation of the robot and its cell, instead of teaching points on the real robot with the pendant.
  • tool center pointThe reference point at the working tip of the robot's tool, such as the tip of a welding wire or the center between gripper fingers. The robot moves and positions this point.
