Safety / Maintenance / Diagnosestelediagnosis, telemaintenance, and teleoptimization
The employment of robot systems which are to work directly with people naturally
places highest demands on system saftey, reliability, and maintainability.
A suitable safety concept must account for the integrity of the system just as it must
account for the integrity of its surroundings. External events affecting the proper
function of the system and internal error conditions must be identified and classified
according to their inherent risk factors.
The capability of performing an exhaustive autodiagnosis is of importance not only with
regards to the safety of the system, but also with regards to offering the untrained user
support in troubleshooting. In the scenarios discussed above involving robotic
household assistants and manufacturing assistants, it cannot be assumed that the
robot will be maintained by thehuman user himself, or that service personnel will be
always and immediately available. This makes it necessary to develop and explore
suitable means of telediagnosis and remote maintenance.
In the case of a failure, intelligent robot assistants must be able to explain both their
internal status and how that status came to be, recommend appropriate steps to
remedy the failure, rectify failures itself where possible, or compensate for them
through appropriate countermeasures (error recovery).
The following research topics are investigated in MORPHA:
