Interleaving Temporal
Planning and Execution for an Autonomous Rover
|
|||||
Abstract Mission planning and execution
for autonomous rovers
with limited resource capacities while moving around
in dynamic environments require to address temporal,
resource and uncertainty issues. The use of a temporal
planner and a temporal executive which processes
are interleaved is desirable. In this paper we propose
a framework to integrate deliberative planning, plan repair
and execution control in a dynamic environment
with real-time constraints. It is based on lifted partial
order temporal planning techniques which produce flexible
plans and allow, under certain conditions discussed
in the paper, plan repair interleaved with plan execution.
This framework has been implemented using the
planning system IXTET, integrated in the LAAS architecture
in interaction with a procedural executive, tested in
simulation and deployed on an ATRV robotic platform.
