If you are trying to deploy a robot on to NOMAN-PC, looks like that device is not properly discovered as the credentials which you have given during the discovery could be incorrect.
When you are running the discovery , once you get to scopes , make sure you have chosen the correct credentials (look at the check mark under WMI for example) to be used from the credentials windows for that PC you are trying to discover . If the credentials chosen are incorrect, it may not get discovered correctly . Once the discovery is complete (when you see OS and other info) you should be able to deploy the robot from USM
