Fingers spinning uncontrollably

[gstavrinos]

Hey Michael,

Thanks for creating this convenient repository.

I have an issue with both of the grippers' fingers in simulation. All of them keep spinning right from the start of the simulation, without even trying to move an arm or hand.

In order to keep them from spinning, I have temporarily set all of the fingers as fixed and not continuous mimic. Since I want to experiment with grasping, this is not an acceptable solution for me.

Do you have any solution in mind?

At this point I should highlight that I am on Ubuntu 18.04 and ROS Melodic.

Thanks in advance,

George

Hey George, I am glad you opened this issue. I know there is this bug and I would like to get rid of it too. I am on Ubuntu 16.04 with ROS Kinetic and same issue (even Gazebo 6 and 7). It has to do something with controller I would think, right?

Hey @michtesar. thanks for your reply. I will investigate the controllers and the URDFs and keep you updated either here, or in our private conversation through e-mails! :)
