Hi,friends,
I want to know the robot kinematics model in the RobotStudio,would anybody know?I have searched some,but have no results.There are DH model and M-DH model and I open the RobotStudio ,I find that the 5 and 6 axis are different from the other axis,the other four axis are based on the base of the robot,and the 5 and 6 axis are based on the other base.

 

Could somebody have some results or give some papers for the model?Thank you!

    Are you looking for the DH-parameters for any robot in particular? RobotStudio uses modified DH-parameters according to Craig's definition. See below for the M-DH parameters for the IRB120:

    Hi,

    is it possible to access these DH values via the API?

    Hi Henrik,

    We're a research lab with the following ABB robots:
    IRB-2600-12
    IRB 140 
    IRB 2400/10

    Would you mind sending over the modified DH parameters for these robots, or directing me towards a place where I could access the parameters?

    Thanks!
    Mike
