Innovations in the field of microelectronics and micromechanics have
enhanced the involvement of "smart" robots in various technical applications.
Unfortunately. no robot is completely reliable. Therefore. up-to-date robots are often
connected with a (repairable) safety device. Such a device prevents possible damage,
caused by a robot failure, in the robot's neighbouring environment. However. the
random behaviour of the entire system (robot, safety device. repair facility) could
jeopardize some prescribed safety requirements. Therefore. an appropriate statistical
analysis is quite indispensable to support the system designer in problems of risk
acceptance and safety assessments. We introduce a robot-safety device system
attended by two statistically different repairmen. Our system is characterized by the
natural assumption of cold standby and by an admissiible "risky" state. In order to
describe the random behaviour of the system. we introduce a stochastic process
endowed with probability kernels satisfying Kolmogorov-type equations. The solution
procedure is based on advanced methods of renewal theory. Next. we derive the
invariant measure of the T-system and the long-run availability of the' robot. Finally.
we consider the particular but important case of fast repair.
