Error when running Simulated Pick and Place example

[ViacheslavRud]

I installed everything required in accordance with
https://sdk.rethinkrobotics.com/intera/Workstation_Setup
https://sdk.rethinkrobotics.com/intera/Gazebo_Tutorial

And tried to run Simulated Pick and Place example with command:
roslaunch sawyer_sim_examples sawyer_pick_and_place_demo.launch
I constantly getting next error

[ERROR] [1588181573.692278, 5.025000]: INVALID POSE - No Valid Joint Solution Found.

In Gazebo arm is moving, trying to take red box, but every time misses to take it. "Claws" going down already closed.

How can I fix it?

Got the same issue. Have you addressed it?
In my evn, the arm cannot go down smoothly, meanwhile error infos are printed.

I also am getting the same issue. Have any of you solved it? I'm running ROS Melodic on Ubuntu 18.04.

@ViacheslavRud, Hi,
did you manage to solve it?

[ViacheslavRud]

@artemiialessandrini Hi,
If remember correctly, unfortunately no. I'm not working on examples now.

Hi!

Sorry for all the inconveniences and not fixing the issue earlier. Pull request #52 resolves similar issues in Noetic, I would be very happy if you guys can confirm that the issues you are experiencing in either Melodic or Noetic are fixed after the pull request.

Thanks!

@AdrianZw Hi, the pick&place demo works perfectly after pull request #52. I am using Melodic.
Also, the SawyerGravityController works normally after #52
It should be good to get #52 merged to the main branch.

[artemiialessandrini]

Yes it works good now, cheers!
