Abstract
In this paper, we discuss Procedural Reasoning Sys­
tem (PRS) as a high level Control and Supervision lan­
guage adapted to autonomous robots to represent and
execute procedures, scripts and plans in dynamic envi­
ronments. We discuss the main reasons why PRS is well
suited for this type of application: (1) The semantics of
its plan (procedure) representation, which is important
for plan execution and goal refinement; (2) Its ability
to construct and act on partial (rather than complete)
plans; (3) Its ability to pursue goal­directed tasks while
at the same time being responsive to changing patterns
of events in bounded time; (4) Its facilities for managing
multiple tasks in real­time; (5) Its default mechanisms
for handling stringent real­time demands of its environ­
