Description

I want to organize a first small discussion about the results of the Robotic Tests we did on the VAXBOX last month.

In this meeting Sergio will present the issues found during the tests and suggest modifications for the modules to facilitate the robotic intervention.

    • 15:30 17:15
      Robotic test presentation 1h 45m
      Speaker: Sergio Di Giovannantonio (CERN)

      Robotic test presentation discussion notes 

      29/11/23

       

      • Module collides with shieling during operation.
        • Study enlarges guiding pins (One longer one shorter even better)
        • Study use of dumpers
        • Study guiding surfaces.

       

      • (M1 Cables may be led by hand from the superior position)

       

      • Antonio: To check with Damien guiding pins positions and lengths.

       

      • Suggestion of exchange the lifting rings with lifting mushrooms, to be studied.

       

      • Suggestion of duplicate the M1 hex head of step 2, may be not possible due to space constraints.

       

      • 35Nm may be too much for the robot.

       

      • Reduce this necessary toque in the module.

       

      • Use a fork special tool for the robot.

       

      • Vacuum and robotics to define a final tight procedure for the bolts.

       

       

      • Improvements proposed for the hex heads.

       

      • Make them more visible.
      • Make them longer.
      • Adjust diameter to ISO. 

       

      • Vacuum radiation resistant valve is out of the project.
        • Proposed solution, use of tungsten shielding
        • Increase in length of the valve and weight of the module 10cm.
        • Module 1 is ok.
        • Check size module 3 (shielding)

       

      • To study going back to 25mm hex pins for the valve actuator

       

      • To check one hex head bended

       

      • Antonio: To check for a similar crane to do balance tests with the robot.
