barrett hand plugin not loaded in rqt under Ubuntu xenial 16.04 w/ ROS kinetic

[anaceri]

Hi there,

I facing an issue of loading the barrett hand plugin either using rqt or via the $rosrun rqt_bhand rqt_bhand under Ubuntu xenial 16.04 and ROS kinetic. In both, I get the following error:

RosPluginProvider.load(rqt_bhand/BHandGUI) exception raised in __builtin__.__import__(rqt_bhand.rqt_bhand, [BHandGUI]):
Traceback (most recent call last):

Any idea?

Thanks in advance!

Hi,

Unfortunately, the rqt_bhand plugin was not migrated to Kinetic and the new qt version, sorry.

Thanks for prompt reply. Any plan to do so? PS. in ROS.org it says this version is also supported in Kinetic.
