There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract:
Through the years, robot manipulation research has widened its application field from structured industrial environments to household scenarios. For a robot manipulator to operate in the latter, it must be able to handle diverse type of objects in order to perform equally diverse manipulation tasks. Although theoretically, a robot could take full advantage of online databases to identify objects and access their corresponding grasping information, we claim that a robot should also have the capability to perceive a novel object, create a suitable representation of it, and generate a manipulation plan in an efficient and online manner. In this proposal, we present a framework to manipulate novel objects to accomplish elementary household tasks. We present our work on object representation based on superquadrics and its direct relation to fast grasp generation. Second, we present an algorithm to generate manipulation plans for pick-and-place tasks by selecting a grasp that maximizes a metric based on a human heuristic (end-comfort effect). Third, in order to define grounded elementary household tasks, we present a study based on human dexterity tests to define benchmark tasks to evaluate our system. Finally, we explore handover tasks, as a final application to our approach, necessary to operate in household environments. We validate our results with experiments on 2 robotic platforms.
