TL;DR
This paper introduces the 'Busboy Problem', focusing on automating efficient decluttering of tableware by using policies for multi-object grasps, significantly improving collection efficiency in robotic tasks.
Contribution
The paper proposes novel grasping policies for multiple items and introduces the Objects per Trip (OpT) metric to evaluate decluttering efficiency improvements.
Findings
1.8x improvement in Objects per Trip (OpT) with multi-object grasps
Effective policies for grasping multiple items simultaneously
Validated results through physical experiments with singulated items
Abstract
We present the "Busboy Problem": automating an efficient decluttering of cups, bowls, and silverware from a planar surface. As grasping and transporting individual items is highly inefficient, we propose policies to generate grasps for multiple items. We introduce the metric of Objects per Trip (OpT) carried by the robot to the collection bin to analyze the improvement seen as a result of our policies. In physical experiments with singulated items, we find that consolidation and multi-object grasps resulted in an 1.8x improvement in OpT, compared to methods without multi-object grasps.
