Abstract: A robotic system includes first and second manipulator assemblies in an operating environment and having separately movable bases. A processing unit is configured to receive first sensor data from a first plurality of sensors disposed on the first manipulator assembly, wherein the first sensor data provide spatial information about the operating environment external to the first manipulator assembly. A first spatial relationship of the second manipulator assembly relative to the first manipulator assembly is determined using data including the first sensor data. A first alignment relationship between the first and second manipulator assemblies is established based on the first spatial relationship. Based on the first alignment relationship, motion of the second manipulator assembly is commanded in response to a command from a first input device operable by an operator.

Abstract: A fault current limiter may include a current limiting leg to transmit a first current and a control leg in parallel with the current limiting leg, the control leg to transmit a second current. The control leg may include a plurality of solid state switches arranged in electrical series with one another; a plurality of current monitors arranged in electrical series with the plurality of solid state switches; and at least one triggering circuit, wherein the plurality of current monitors are electrically coupled to the at least one triggering circuit, and wherein the at least one triggering circuit is optically coupled to the plurality of solid state switches.
