SCARA IRB910SC robot_Axis 3_4

Hi all,
I have a concern about the operation of axis 3,4 in scara 910SC. As you see, they use 2 motors:

  • 1 motor to transfer rotary motion to liner as axis 3 motion (shaft_3).
  • 1 motor to rotate shaft _3 to become axis 4.
    → so my concern is how to do 2 motions like that with only applying 1 shaft.
    Who can make it clear? thanks.


any ideas for this mechanism guys?
