Robot On A Rail Questions

    I have not worked with a robot on a rail yet and starting to set it up in Roboguide. I want to use Group 2 of the robot but wondering what the best way to set this up would be? The robot will be picking from different bins along the rail and i want the motion to be smooth and look fluid without any waisted motion. i have the multigroup option and also extended axis options

    When setting this up in roboguide what is the best option to pick while configuring the robot? should i choose Basic Positioner, General Positioner, Independent Axes, or Rail Unit? And how do these choices get setup in the real robot?

    I always highly suggest extended axis. Avoid Group 2 if you can.

    1. DCS is a nightmare if your rail is setup for group 2. Fencelines/operator spaces move with the robot.
    2. Any type of frame shifting/ work in cartesian space is a nightmare because the robot doesn't know its moving when the RTU is moved.
    3. If you have to reposition your RTU, you have to reposition your robot as well. With extended axis, you have (World 'S' G1) motion type which will keep your TCP in the same point in space while you jog your rail axis, and move group 1 to account for the rail motion.

    ok let me try this setup because i am in the process of setting up IIC and cant get it to work at all! probably because its setup in group 2. Thank you!
