Hi. I’m new to ROS and UR and I want to use a PC to control our UR5e.
I follow the guide on Universal_Robots_ROS_Driver and when launching the ur5e_bringup.launch there are scrolling errors ‘Could not get fresh data package from robot’ in the terminal. If I start the external_control on ur pendant, there will show up a message telling ‘Ready to receive control commands’, but still reporting same errors.
Seems that there’s no error on the UR5e pendant.
Enviroment:
Host PC Win11 with Ubuntu18.04 and ROS Melodic installed on Virtualbox
Using a cable to connect my PC and UR5e
In Virtualbox adapter bridged on Host PC’s ethernet adapter (which is connected with UR5e through a cable)
Really appreciate your help!!
Thank you
is the UR controller in local or remote mode?
Hi @filoucs , Do you mean the setting on the top-right of pendant? If yes that is in the local mode. If I switch to remote, I couldn’t start the external_control program, and the PC couldn’t get connected
Okay I finally solved the problem by using Ubuntu on host pc rather than using virtualbox VM…
Seems that virtual machines do influence the communication quality sometimes.
Thank you
