Dear Developers,
I am trying to execute motion planning on robot arms but cannot get it work.
This https://drive.google.com/file/d/0B3-BbM ... sp=sharing links to the image, which shows the setting i have and the problem i faced, namely, when i compute phase 1 nodes, it warns "Nodes could not be computed: the motion planning parameters are ill-defined."
Not sure how to get it right since litter documentation is provided for motion planning task
Thanks a lot!
Yours sincerely,
Juekun
How to make motion planning work?
Re: How to make motion planning work?
Hello Juekun,
your motion planning task is defined with 9 joints. You shouldn't include the gripper joints, since that is not part of the motion planning task (or the associated IK group). Just specify the first 7 joints.
At first also, do not perform any collision detection. Try to have it run first in a simply way.
Also, make sure that the Ik group you specify is tagged as explicit handling.
If that doesn't work, send us your scene.
Cheers

Hi Marc,
Thanks for your reply!
I have made the changes you suggested but it doesnot work so i attach the scene file as the link below
https://drive.google.com/file/d/0B3-BbM ... sp=sharing
it is actually the same with the file forwardAndInverseKinematics2.ttt, on which i want to add motion planning modules but don know how.
Thanks a lot

Re: How to make motion planning work?
If I load your scene and click Compute phase 1 nodes, it works. You can verify it by checking Visualize phase 1 nodes (the phase 1 points are hardly visible on the grey floor, you might have to rotate your scene a bit to see them)

Hi Marc,
Thanks a lot! Problem solved!
It seems that early version of VREP doesnot work so i switch to the latest version.
By the way, could you add on more details on the motion planning documentation in the manual since it is really an important part of my work!
Thanks a lot
