Concurrent planning and execution for autonomous robots
Reid G. Simmons · IEEE Control Systems · 1992
The task control architecture (TCA) provides communication and coordination facilities to construct distributed, concurrent robotic systems. The use of TCA in a system that walks a legged robot through rugged terrain is described. The walking system, as originally implemented, had a sequential sense-plan-act control cycle. Utilizing TCA features for task sequencing and monitoring, the system was modified to concurrently plan and execute steps. Walking speed improved by over 30%, with only a relatively modest conversion effort.>
