High Performance Execution of Everyday Pick-and-Place Tasks by Integrating Transformation Planning and Reactive Execution (bibtex)
by L Mösenlechner, A Müller and M Beetz
Abstract:
We investigate the plan-based control of physically and sensorically realistic simulated autonomous mobile robots performing everyday pick-and-place tasks in human environments, such as table setting. Our approach applies AI planning techniques to transform default plans that can be inferred from instructions for activities of daily life into flexible, high-performance robot plans. To find high performance plans the planning system applies transformations such as carrying plates to the table by stacking them or leaving cabinet doors open while setting the table, which require substantial changes of the control structure of the intended activities. We argue and demonstrate that applying AI planning techniques directly to concurrent reactive plan languages, instead of using layered software architectures with different languages, enables the robot action planner to achieve substantial performance improvements (23% - 45% depending on the tasks). We also argue that the transformation of concurrent reactive plans is necessary to obtain the results. Our claims are supported by extensive empirical investigations in realistic simulations.
