Position and Orientation Identification of Platform Manipulators

Abstract

A novel approach is developed for identifying both the position and orientation of the base joints of modular platform manipulators. This new approach first establishes a spherical triangle to isolate and solve for one of the unknown placement parameters. With the reduced complexity, a closed-form formulation is then developed for the remaining unknown parameters through Dialytic Elimination for two identification poses. The identification process with the presented method is illustrated with a numerical example.
