Abstract: Disclosed is a robot apparatus with a capable and highly maneuverable drive system incorporating two differential swerve drive pods. The robot apparatus further includes a claw mechanism for grasping an object, a passthrough mechanism for moving the object horizontally and a lift mechanism for moving the object vertically. The robot apparatus allows for rapid manipulation and movement of objects such as cones.

Abstract: A collaborative autonomous ground vehicle or robot for traversing a ground surface is disclosed. The robot is a wheeled vehicle includes two camera groups and other sensors to sense the environment in which the robot will operate. The robot includes a control system configured to operate in a teach mode to learn a route by either following a person or preceding a person and to store the learned route as a taught route. The control system is configured for identifying persons and objects, such as obstacles, within the fields of view of the camera groups. When the robot is in its repeat mode it will take the taught route over the ground surface and take appropriate action if an obstacle is identified in the field of view.

Abstract: A high capacity suction strainer for a nuclear reactor has a frame, a flow-through plenum, and a filter array. The flow-through plenum is mechanically mounted to the frame and has a plurality of inlets and an outlet. The filter array is also mechanically mounted to the frame and has a plurality of filter groupings in fluid communication with the inlet on the plenum.
