I will start by pointing out that theÌýmotion planning problem of robotics is equivalent to the task of finding a section of a specific fibration. The notion of Schwartz genus allows to quantify the complexity of this problem.ÌýThe main part of the talk will be based on a recent joint work with Dan Cohen and Shmuel WeinbergerÌýwhich deals with parametrised motion planning, i.e. with motion planning algorithms which are in some sense universal,Ìýthey are applicable to a variety external conditions (such as positions of obstacles etc) which are viewed as parameters.Ìý
