Paper Abstract

Telerobotic systems (TRSs) and shared teleautonomous systems result from the integration of multiple sophisticated modules. Procedures used in systems integration design decision-making of such systems are frequently ad hoc compared to more quantitative and systematic methods employed elsewhere in engineering. Experimental findings associated with verification and validation (V&V) are often application-specific. Furthermore, models and measurement strategies do not exist which allow prediction of overall TRS performance in a given task based on knowledge of the performance characteristics of individual subsystems. This paper introduces the use of general systems performance theory (GSPT), developed by the senior author to help resolve similar problems in human performance, as a basis for: (1) measurement of overall TRS performance (viewing all system components, including the operator, as a single entity); (2) task decomposition; (3) development of a generic TRS model; and (4) the characterization of performance of subsystems comprising the generic model. GSPT uses a resource construct to model performance and resource economic principles to govern the interface of systems to tasks. It provides a comprehensive modeling/measurement strategy applicable to complex systems including both human and artificial components. Application is presented in the context of a distributed telerobotics network (Universities Space Automation and Robotics Consortium) as a testbed. Insight into the design of test protocols which elicit application-independent data (i.e., multi-purpose or reusable) is described. Although the work is motivated by space automation and robotics challenges, it is considered to be applicable to telerobotic systems in general.
