HOW-TO: Update the ER-FLEX robot

Jacob Kastrup


For software versions 1.2.23 and older please contact for information on how to update the robot. The version number can be found in the lower left corner of the web-interface:

Updating the robot

For versions 1.2.24 and newer, updating the robot is a 2 step process.

1. Downloading the new release

Downloading the update file currently requires that the robot is connected to the internet. Connecting to a WiFi hotspot can be done by going to SYSTEM -> NETWORK.

After connecting the robot to the internet,  go to SYSTEM -> SETTINGS -> Software Update

From here, enter the desired version into the "Download new version" field and press "Download".

See the Software Releases Forum for information on the latest software version.

Note: Releases are about 9 GB so it might take a while depending on your internet connection.

When the download is finished (Indicated by a green check-mark), go to the "Active version" menu, select the newly downloaded version and press "Apply".

Restart the robot by turning it off and on again as described in the manual.

2. Updating the Ability URCaps

Go to the Downloads page (login required) and download the corresponding version of the Ability URCaps.

Save the Ability URCaps to a USB-stick and insert it into the teach-pendant on the robot.

Press the "Hamburger" menu in the top right corner of the teach-pendant and go to Settings -> System -> URCaps.

From here press the "+" to add the new URCaps. Open them one by one in the file system and press "Restart" to activate the new versions.


The robot is now updated. Confirm the update by connecting to the robot and checking the version number in the lower left corner of the web-interface. Make sure to check out the release notes for the update on the Software Releases Forum.
