Regrasp Planning using 10,000s of Grasps
This paper develops intelligent algorithms for robots to reorient objects.
Given the initial and goal poses of an object, the proposed algorithms plan a
sequence of robot poses and grasp configurations that reorient the object from
its initial pose to the goal. While the topic has been studied extensively in
previous work, this paper makes important improvements in grasp planning by
using over-segmented meshes, in data storage by using relational database, and
in regrasp planning by mixing real-world roadmaps. The improvements enable
robots to do robust regrasp planning using 10,000s of grasps and their
relationships in interactive time. The proposed algorithms are validated using
various objects and robots
