Issue with Camera and Robot Coordinate Alignment – RV-4FL-D with CR750-D Controller

    Hello everyone,

    I am working on a project with a Mitsubishi RV-4FL-D robot and a CR750-D controller. In this setup, I use a Cognex camera mounted on the gripper to capture an image and extract the X and Y coordinates of an object. These coordinates are then sent to the robot, where I assign them to a position as follows:

    P1.x = Xcam
    P1.y = Ycam

    I have already performed the camera calibration and created a base coordinate system, ensuring that both are aligned. However, I have noticed that when I compare the same point from the robot’s perspective and the camera’s perspective, the coordinates do not match.

    I am trying to understand what might be causing this misalignment. Could it be related to:

    • Incorrect calibration of the camera or base?
    • A transformation that needs to be applied to the camera coordinates before sending them to the robot?
    • An issue with the reference frame in the robot?

    Any guidance or suggestions would be greatly appreciated!

    Thank you in advance.

    Best regards,
