+# Hand Eye Calibration with RoboDK
+
+Hand-eye calibration is a necessity for any picking scenario that involves a camera and a robot.
+This sample offers an easy and adaptable method to perform hand eye with a variety of robots that are supported in RoboDK.
+
+For more on Hand-Eye Calibration, please see the [tutorial](https://support.zivid.com/latest/academy/applications/hand-eye.html) in our Knowledge Base.
+
+If you need help with the sample, visit our Knowledge Base article [here](help.zivid.com) (To be updated)
+
+This sample is made and modeled with a Universal Robots UR5e robot.
+It is a requirement that you make your own poses that suit your environment.
+If you have a different robot from a UR5e you will need to load in the corresponding robot to your rdk file.
