Currently, there is no UIM/ ROBOT PSM.
In the past clients have always been able to use newer robots with old version of UIM.
Starting with the 7.9X version of robot and hub it has been recomended on the hub that the robot and hub probe version be the same.
The robot machines reporting to the hub can be older versions or new versions without an issue.
The UIM version really has to do with the CORE probe on the primary hub and the database scemea versions.
as the robots do not talk directly to these probes in most cases and do not interact with the database, updating to newer robots on monitored machines has never been much of an issue.
The new 7.95+ robots for the first time in many years is adding some new key functionality.
this of course will not work without the newer version of UIM the activates these features namely MCS with enhanced profiles.
But this will not prevent them from working on supported platforms with older versions of probes the way older robots worked.
