Hi,

I am creating simulation to understand robot workspace singularities. to aid my research i have a 2 link robot similar to the SCARA robot minus the prismatic joint for variation in Z direction.

I have been trying to get readings out, and i have been using a graph and exporting the data through a CSV.

I want to know the angular velocities of the links, and am looking for a solution to best help my problem.


thanking you in advance

Hello,

you can have your graph record time derivative values. Or you can directly select the graph data stream Joint: velocity. Or you can track the position of your joints inside of a child script, and do the derivation and export yourself from there.

Cheers

Hi,

How do i track the position of the joints through a child script? I worked out the orientation of the joints(angles) and the values i am getting through the graph seems to be wrong.

thanks

Please give a concret example of what is not working, so that we can reproduce it. Otherwise it is difficult to help.

Cheers
