From the results of this comprehensive functional test conducted by AUBO robot i5, it can be seen that AUBO robot pose accuracy and pose repeatability and track accuracy and orbit repetition are two important functions of the robot, which have surpassed most domestic brands
The reason for the good accuracy performance of AUBO collaborative robots
  1. Changes in the accuracy of multi-directional postures

The change of multi-directional pose accuracy shows that when the same command pose is responded n times (n≥10) from three mutually perpendicular directions, the error between each uniform pose is realized.

2. Track accuracy and track repeatability

Orbital accuracy indicates the robot's ability to move its mechanical interface n times along the command track in the same direction. It also refers to the end of the robot actuator to track a specific track movement, and practice the error between the motion curve and the ideal motion track;

Orbital repeatability indicates that when the robot repeats the same instruction track n times, the degree of commonality of the orbits is realized. In simple terms, it refers to the error between the actuators of the robot end repeatedly staring at the same ideal motion track and practicing the motion tracks;

This indicator can largely express the dynamic tracking function of the robot, and in many practical applications (such as arc welding, gluing, etc.), the requirements for this indicator will be higher.

3. The moment of stability in the azimuth

It is a function used to measure the speed of the robot's abortive posture in place;

Fourth, the azimuth overshoot

It is used to measure the ability of the robot to stop smoothly and accurately in a solid position.

5. Pose accuracy and pose repeatability

Pose Accuracy (AP) is what we often call positioning accuracy, which indicates the error between the command pose (theoretical pose) and the actual pose uniformity value when approaching the command pose from the same direction. In simple terms, it refers to the degree of proximity between the practical arrival orientation of the robot's end actuator and the target orientation (theoretical orientation). In professional applications, if the position and posture accuracy of a robot in the working space reaches about ±1mm, it is a very good function. Generally speaking, industrial robots can be calibrated to improve the azimuth accuracy to within ±1mm.

Pose repeatability (RP) is what we often call repeatability accuracy, which indicates the commonality of the pose after repeated response n times (n≥30) from the same direction to the same command pose. To put it simply, it refers to the proximity between the actuators of the robot to repeatedly reach the same target direction (ideal orientation), and the practice of proximity between the arrival directions.
