About

J. Zachary Woodruff is a roboticist whose work pushes the boundaries of dexterous manipulation, focusing on how robot hands can dynamically control objects through sliding and rolling motions. His key research areas include in-hand sliding manipulation and robotic contact juggling, where he develops frameworks for robots to precisely reposition objects without a firm grasp. Woodruff’s major contribution is a pioneering framework for dynamic in-hand sliding, which uses a soft-finger limit surface contact model to plan how multiple fingers create inertial loads that cause a grasped object to slide in a controlled way. This work, published in 2017, has garnered 124 citations, reflecting its influence on the field. He also defined and advanced the concept of “robotic contact juggling,” where a robot manipulator purposefully controls a 3D object as it rolls freely on the hand—a feat inspired by the manipulation of a spinning ball. His 2023 paper on this topic has already earned 10 citations, marking it as a notable achievement. Woodruff’s research is essential reading for anyone interested in agile, human-like robot manipulation.
