Abstract:
Construction equipment is typically massive and operated
manually with minimal use of sensors or computers for
measurement or control. Research in the Intelligent
Systems and Structures Divisions at the National
Institute of Standards and Technology has explored
innovative ways to use sensors, computers, and
light-weight tensioned cable machines for heavy
manufacturing and construction tasks such as lift and
position of heavy loads and manipulation of tools and
parts for assembly, fixturing, welding, cutting,
grinding, machining, macro stereo-lithography, and
surface finishing. Recent research has yielded novel
concepts for movable scaffolding and worker positioning
systems that enable workers to maneuver themselves,
parts, and tools throughout a large work volume for
tasks such as ship repair and aircraft paint removal.
