When to Update PolyScope X
Universal Robots periodically announces updates for PolyScope. Once Hirebotics has tested and approved an update, you'll receive a notification to update your robot. Updating PolyScope enables you to access the newest features, resolve known issues or bugs, and enhance system security and connectivity.
For software compatibility reasons, we recommend only installing specific PolyScope X versions. See the PolyScope X Version Support Matrix for more details. If in doubt, please contact Beacon Support.
