## 6.849 Geometric Folding Algorithms: Linkages, Origami, Polyhedra

**6.849 Geometric Folding Algorithms: Linkages, Origami, Polyhedra (Fall 2012, MIT OCW)**. Instructor: Professor Erik Demaine. This course focuses on the algorithms for analyzing and designing geometric foldings.
Topics include reconfiguration of foldable structures, linkages made from one-dimensional rods connected by hinges, folding two-dimensional paper (origami), and unfolding and folding three-dimensional polyhedra.
Applications to architecture, robotics, manufacturing, and biology are also covered in this course.

Lecture 12 - Tensegrities & Carpenter's Rules |

This lecture covers infinitesimal rigidity and motion, and tensegrity systems as an extension of rigidity theory. The rigidity matrix, equilibrium stress, and duality are introduced, and a proof to Carpenter's Rule Theorem is presented.

Class 12 - Tensegrities |

This class covers several examples of tensegrity structures and in Freeform software. A question on linear programming's application to the motions and stresses is addressed.
