What is the accuracy of the Wrist camera?

We have often the questions about the accuracy of the wrist camera. It's a difficult question but here is some answer. 

Looking at the specs of our wrist camera, we have the following, depending on the robot model: 



Under good conditions, I would say that we can do better than +/-3mm, but I wouldn't say we can reach +/-0.1mm. Our wrist camera is good for parts recognition and regular pick and place, maybe you could look into an inspection camera if you seek greater accuracy. 

The best is to know what is the application. To see what could help. Maybe force sensing could be used to get more accuracy.
