Universal Robot Safety Password

If you need to access the safety configuration but the password is unknown you can remove it.

Log in using an SFTP client (WinSCP) or through SSH.

  • Username = root
  • Password = easybot

The folder you arrive in will have a file called:

Remove this file and restart the robot. Now the safety password can be set up again.

Is this possible with the UR5 robot? Is there a way to factory reset the UR5 also?

Hey Austin,

Sorry for the late reply.

Yes it is possible to login to the UR5 robot this way.

What do you want to do exactly? Do you want to use a fresh installation file?

Or do you want te replace the image with a fresh one?

NOTE: Reflashing your SD card or USB stick will delete all your programs and calibration files, make sure you always have a full backup before doing any memory replacement or image re-install.

Hi Mathijs,

What do you mean “Log in using an SFTP client (WinSCP) or through SSH”? It´s via PolyScope?

Sorry for my noob question, i not from IT and from what i google it´s i do not understand…

Welcome @N_R_PT ,

First of all it is not a noob question. I’ll walk you through it real quick.

The Universal Robot runs on Linux. You only see the User Interface on the teach pendant, but you can actually login to the Linux OS that is running on the robot.

Linux has a sepcial remote login port which you can use to login to execute commands or transfer files.

One way of doing so is to use WinSCP :: Official Site :: Download

Once you have downloaded and installed WinSCP on a laptop / PC you can connect to the robot, see screenshot below.

Default credentials are
user: root
password: easybot

Hope this makes things clear.

This is very helpful! But how do I know what my port number is? And the program is telling me that my host number “does not exist”. Would you happen to know why?

Hi Mel,

It should be the default port, which is 22.

What is your network configuration? You probably need to set your IP address on your ethernet adapter.

Make sure to set the robot IP, you can use this guide, page 5:

Make sure the IP address is in the same range, and the subnet mask is the same. The IP address range is different in the screenshots, don’t get confused by that!!

Hopefully you can get things to work now.
