Abstract:The field of robotics has developed at a promising speed these years, and its potential usage is tremendous in both traditional industry and frontier research. Motion planning, as an important branch of robotics, is the process of completing tasks and avoiding obstacles while achieving optimization at the same time. Even though many ad hoc algorithms have been proposed to solve such problems, most of them will deal constraints and optimization separately. As a result, there is an urgent need for an algorithm to handle them together. With the aim to solve this problem, this paper introduces a new method with the help of homotopy, and such a method and its application for motion planning is examined comprehensively. This method will assemble all holonomic, non-holonomic, and obstacle constraints into a metric. Furthermore, applying partial differential techniques on this metric allows continuously deforming an arbitrary path into another one in the configuration space. A shortest path will be found that satisfies all given constraints such as obstacles and implementation requirements. The corresponding mathematical and control background will be reviewed. Then this thesis will present the details of the homotopy method and how to implement it in reality. Finally, two models with different degrees of freedom will be examined to look at the feasibility of such a method.
