How to connect to a real universal robot (ur3)

edit

Hi,

i try to connect ROS from a virtual box (ubuntu 16.04 + kinetic) with a real universal robot (ur3.5.1). I used the modern_driver and the moveit config from universal_robot package. I am able to ping to the robot and the actual position is shown up in the RVIZ interface (even if you move the robot), BUT if i try to plan and execute a trajectory it 'fails' and the robot doesen't move. Also the test_move.py don't work (the connection is build successfully but the robot don't move). On the teach penal of the robot i don't set any special config (just unlock the joints and enable networking) Do you have any idea? Maybe it is because of the virtual box?

Thank you!

Driver:
