Have you solved this issue now? We have also encountered this problem, and our 'width' parameter is not working either.
Hello! No, we have not really found a solution for it. In the end we control the closing of the gripper manually using the set_position
interface. We have fingertip sensors that allow us to measure the applied force and thus we stop according to their readings. You could also try to monitor the position and stop according to a decrease in change. One thing to note is that we also rewrote (not a huge deal, but with mentioning) the gripper node because the gripper would not open reliably. This is because the c++ gripper API is blocking while it executed a position command and cannot be interrupted. The timeout is also hard coded and seems to be more than a minute.
Hope this gives you an insight. If you are interested, I can share our gripper node in the next days.
Dear Franka Development Team, thanks for the tools. A colleague (https://github.com/ARoefer/) and I are confused about the
force
set when performing aGraspAction
using a Panda robot.Please see the MEW below. When running, we can neither feel nor see a difference (grasping a sponge), when we apply the different force values.
We are running the latest available version through
apt
(ros-noetic-franka-ros (0.10.1-1focal.20240125.211037)
) and Panda system firmware4.2.2
and robot firmware1.3.4-F-AX
(last entry1.3.4-F-A7
). It says thoughFranka Hand: Disconnected
.We hope there is a quick solution to our problem. Please let us know if you need any further information.
Cheers, -Nick
