Towards Plan Transformations for Real-World Mobile Fetch and Place

Abstract

In this paper, we present an approach and an implemented framework for applying plan transformations to real-world mobile manipulation plans, in order to specialize them to the specific situation at hand. The framework can improve execution cost and achieve better performance by autonomously transforming robot’s behavior at runtime. To demonstrate the feasibility of our approach, we apply three example transformations to the plan of a PR2 robot performing simple table setting and cleaning tasks in the real world. Based on a large amount of experiments in a fast plan projection simulator, we make conclusions on improved execution performance.
