Modern Robotics, All Videos - Modern Robotics, Chapter 12.2.3: Force Closure

This is a video supplement to the book "Modern Robotics: Mechanics, Planning, and Control," by Kevin Lynch and Frank Park, Cambridge University Press 2017. See http://modernrobotics.org for information on the book, free software, and other materials. This video introduces the conditions for force closure (or a force closure grasp), which occurs when a set of frictional contacts on a rigid body can generate an arbitrary wrench to counteract a disturbance wrench. The conditions are expressed as a linear program for the general case as well as graphically for the planar case. The conditions for force closure are identical to the conditions for first-order form closure if all contacts are frictionless. This video is a brief summary of material from the book, and it is not meant to stand alone. For more details, such as an explanation of the notation, please consult the book and the other videos.
