Set velocity limit for Pilz Planner

edit

Hi everyone,

i have an universal robot ur5e and can control it with ros+moveit. I use ompl or chomp for planning.

Now i want to try the Pilz planner, where problems begin. I install the Pilz planner package and copy the pilz_command_planner_planning_pipeline.launch.xml file in my launch directory. I can launch moveit with the pilz_command_pipeline, but while starting the error

Exception while loading move_group capability 'move_group/MoveGroupExecuteService': MultiLibraryClassLoader: Could not create object of class type move_group::MoveGroupExecuteService as no factory exists for it. Make sure that the library exists and was explicitly loaded through MultiLibraryClassLoader::loadLibrary()

appears. But at the end of booting i see:

[ INFO] [1625746415.465549752]: MoveGroup context using planning plugin pilz::CommandPlanner
[ INFO] [1625746415.465605026]: MoveGroup context initialization complete

You can start planning now!

Testing it with RViz, choosing PTP planner i got the error:

[ERROR] [1625746966.020478861]: velocity limit not set for group endeffector
[ERROR] [1625746966.020622564]: Exception caught: 'velocity limit not set for group endeffector'

Can anybody help me? I dont know where i can set the velocity limit. Changing the velocity in RViz doesn't help. In future i want to use python for control the robot using a script like this. But this doesn't work at all right now.

Thanks
