Abstract

Some robotic tasks usually achieved through motion control – trajectory tracking control – can be also well performed by resorting to “path control” philosophy. This is the case for applications where motion coordination among the robot joints is more important than joint tracking of a timed desired reference. This paper illustrates this concept by means of two academic case studies – theory and experiments – using a two degrees-of-freedom direct-drive revolute arm.
