Grasping of unknown objects with neither appearance data nor object models given in advance is very important for robots that work in an unfamiliar environment.

Reducing the grasp candidates for unknown object grasping while maintaining grasp stability is the goal of this paper. In this paper, we propose an efficient and straight forward unknown object grasping method by using concavities of the unknown objects to significantly reduce the grasp candidates. Shortest path concavity is first employed to...
