Abstract
Humans often change the geometry of flexible objects during manipulation so that the goal is easier to accomplish with either simple motions or simple controls. This paper explores how to change the geometry of a knot to allow simpler tying or untying. The paper presents algorithms that modify the knot configuration to allow the knot to be arranged into the correct topological structure or untangled by moving the tip of the string along a straight line, with only a few re-grasps. The paper also presents proof-of-concept physical experiments in which robot arms arrange and untangle several knots.
