Utilizing the topology of configuration space in real-time multiple manipulator path planning
MetadataShow full item record
This article provides a set of algorithms that allow qualitative information regarding the connectivity of configuration space to be quickly established. A mechanism is presented that utilizes these results to determine the effects of the motions of one manipulator on the configuration space of the other. These algorithms are then used as a basis for a simple planner that is capable of rapidly computing collision-free paths for multiple SCARA manipulators operating within overlapping workspaces.
