Excerpt from How to Move a Chair Through a Door
To move a given chair through a door, a natural question is how wide the door should be. The minimum width of a passable door is called the width of the chair. The question was first raised by Gilbert Strang [str82] who studied the case of convex chairs in two and three dimensions.' We focus on the polygonal chairs in this paper but allow non-convex chairs. Although the notion of width for convex chairs is easily captured, the width of non-convex chairs admits several reasonable interpretations. We will note three possibilities in this paper.

Paperback. Zustand: New. Print on Demand. This book explores how to solve motion-planning problems in robotics, where a robot must plan its movements to navigate around obstacles in its environment. The focus of this book is on one specific type of motion-planning problem, known as the door-width problem. The door-width problem asks how wide a door must be for a given robot to pass through it. The author develops an algorithm that can compute the door-width of a robot in O(n^2) time, where n is the number of vertices in the robot's polygonal representation. This algorithm is optimal among algorithms that must construct a graph of size O(n^3). The author also discusses several other related problems, such as the ring-width problem and the elastic width problem. These problems ask how wide a ring or an elastic band must be for a robot to pass through it. The author concludes by discussing the significance of these insights on the broader field of motion planning.
