Abstract
Systems and methods for automating robotic end effector alignment using real-time data from multiple distance sensors to control relative translational and rotational motion. In accordance with one embodiment, the alignment process involves computation of offset distance and rotational angles to guide a robotic end effector to a desired location relative to a target object. The relative alignment process enables the development of robotic motion path planning applications that minimize on-line and off-line motion path script creation, resulting in an easier-to-use robotic application. A relative alignment process with an independent (off-board) method for target object coordinate system registration can be used. One example implementation uses a finite-state machine configuration to control a holonomic motion robotic platform with rotational end effector used for grid-based scan acquisition for non-destructive inspection.
