Collision free pick up and movement of large objects

Conference ·
OSTI ID:639728

An automated system is described for the sensor-based precision docking and manipulation of large objects. Past work in the remote handling of large nuclear waste containers is extensible to the problems associated with the handling of large objects such as coils of flat steel in industry. Computer vision and ultrasonic proximity sensing as described here are used to control the precision docking of large objects, and swing damped motion control of overhead cranes is used to control the position of the pick up device and suspended payload during movement. Real-time sensor processing and model-based control are used to accurately position payloads.
