These are new in Companion 8.5 and ATOS/CX 12.1, and allow the robot to sustain specific injuries as a consequence of damage. (Civilian units without the ATOS/E combat add-on are not subject to them.) Some malfunctions can be resolved through normal repair, either using a handheld repair tool or a normal repair station, but others require the use of a maintenance dock, such as the VectorLogix Diagnostics Bed.

To determine what components are damaged, use the sentinel command (or "@sentinel" if self-operating). This will report where the damage is, but not the specific problem. By looking at the relevant sections in the Robot Hardware Handbook and correlating symptoms, you can determine exactly what is necessary to resolve the issue.
