i taught the robot to detect an object, and i saved the  movement toward the object.
When i try the program the robot won't make the registered movement. He started moving in wrong directions after i change the position of the object  from the teached position

Hi @TheoSaify

Did you used a moveL and set the snapshot variable used in the cam locate as the feature? 

Hello, yes i chose the snapshot variable used.
But what should i choose for the TCP ?

@TheoSaify 
You can use your correctly set tcp. If it still not working, please try to reteach the positions, and redefine the position of the object in the camera locate node. 

can you show me how ?

how can i know that i configured the tcp correctly ?

What is the tool installed on the robot?  You can enter the distance of the tool from the robot flange.
Even if you did not enter the TCP correctly, correctly, you should still be able to use the camera and pick objects.
