Abstract: Computer scientists are often concerned about lower bounds:  what is the least amount of time or memory required to solve a problem? This talk will explore a few fundamental problems in robotics from an equally minimalist perspective, motivated by problems in motion planning and manipulation of flexible materials including paper, cloth, and string. What is the fastest trajectory to move a vehicle with particular motion capabilities from one location and orientation to another, among infinitely many possible trajectories?  How many fingers are needed to immobilize a bendable (but not stretchable) piece of cloth? How many degrees of freedom (motors) must a mechanism have to tie a knot in a piece of string? We will show analytical and geometric solutions to each of these problems, as well as a few machines built based on algorithms and principles discovered.
