Trying to figure out what is a2 & a2 in "Build/modify mechanisms or robots" page when we configure "2 rotative axes" ?

[Olivier]

The first A2 refer to the orientation of the FbHb frame while the second A2 refer to the translation distance between Fb and FbHb. Both are relative to the the X-axis vector.

I have a weird robotic arm. I am not sure if it is industrial robot or collaborative robot. 

I have the arm links designed and know which two links join and their rotations.

Is there a way I can define a custom robot mechanism other than the one already provided?

I am thinking along the lines of if you see in this video how the robot parts are separate and with "joint" command of Fusion 360 the pieces are put together. https://www.youtube.com/watch?v=4YTZ9FGB7jU&t=203s". Then the angles are varied to move the robot.

I don't know a way in Fusion 360 to define start and end point of robotic arm and arm will path plan accordingly. I am still learning RoboDK. I believe RoboDK has the feature that you define start and end point and it can figure out the motion path. That is why i am inclined to explore more in RoboDK. Thank you for understanding and any direction.

I can understand this video of pick and place "https://www.youtube.com/watch?v=FRnWPXQr1G8". For me to reach here, I need to first create the custom robot model mechanism and hence this request.
