How to define a Snapshot Position

Annick_Mottard 2016-10-26

Hey Pros,

Here is another How-to video concerning the Wrist Camera. In this one, I go through the steps of defining a new Snapshot Position. During this process, keep in mind that the actual Snapshot Position can be different than the position used for the calibration step. Thus, when you are at the step of defining and saving the Snapshot Position, adjust the robot's position according to the work plane and to your part's size. When you are at the calibration step with the board, you can move the robot further away in order for the Camera to see the entire board.

You will notice the newer calibration board, not released yet, that contains both boards for the UR3 (smaller board) and the UR5 and UR10 (larger board). As of today, the board for calibration over UR3 has to be downloaded and printed from our support website.

Feel free to post questions here!

Thanks that's nice. I always thought that the snapshot position for the part in the program and the snapshot position for the calibration needed to be the same. That helps when looking at smaller parts that you want the camera to be closer to the object than when it is at the calibration snapshot position. However, do you know if having a different snapshot position for the part and the calibration board has an impact on the accuracy/precision of the system?

In order to keep a good precision, you must place the board on the work plane where your parts will be. Even if you need to move the robot further away in order for it to see the whole board, placing the board on the work plane used for your Snapshot position will ensure a good precision. Putting the board in a different location than your work plane to do the calibration step will decrease the part detection precision.
