Caging Polygons with Two and Three Fingers by Vahedi, Mostafa, van der Stappen, A. Frank

“…We study two- and three-finger caging grasps of a given polygonal object with n edges. A grasp is said to cage an object when it is impossible to take the…”

Energy-Bounded Caging: Formal Definition and 2-D Energy Lower Bound Algorithm Based on Weighted Alpha Shapes by Mahler, Jeffrey, Pokorny, Florian T., McCarthy, Zoe, van der Stappen, A. Frank, Goldberg, Ken

“…Caging grasps are valuable as they can be robust to bounded variations in object shape and pose, do not depend on friction, and enable transport of an object…”
