Abstract: An articulated mechanism is included in an articulated pointing system. The articulated mechanism includes first, second, and third spherical joints, and a first, second, and third lever. The first and second spherical joints are linked by the first lever. The first lever includes a first projecting portion. The first and third spherical joints are linked by the second lever, the second lever including a second projecting portion projecting in an opposite direction of the first projecting portion. The second and third spherical joints are linked by the third lever, such that the longitudinal axes of the first lever and of the second lever are perpendicular. The articulated pointing system includes a basement platform and a mobile platform joined by two articulated hinges. The hinges are moved by actuators. The articulated mechanism has the first lever attached to the mobile platform and the second lever attached to the basement platform.

Abstract: An automated ply layup system uses a robot and an end effector for selecting plies from a kit and placing the plies at predetermined locations on a tool by further employing cameras for ply location detection, a laser scanner for detection and ply placement within a location on the tool, and compact sensors for compacting plies onto the tool.

Abstract: A preferred utility cart includes an elongated base and push handles on either end. The elongated base is supported at its center by a carriage having a pair of wheels. It is supported at each of its ends by a carriage having a pair of casters. Preferred methods of constructing the carriages are described.
