The objective of this proposal is to describe an automated (or semi-automated) lightweight, low-cost handling system for lauch & recovery of offboard vehicles which can be fitted to existing Navy ships or designed into new classes of ships. Many of the systems required for this effort are either in preliminary development of have been developed. It is intended that by combining existing offboard handling techniques and integrating new technologies, a suitable system can be offered and demonstrated in a reasonable amount of time. The non-hydraulic systems to be developed and demonstrated as a result of this using modern Direct Torque Control variable-speed electric drives and Remote-controlled automation control systems. Reduced manning, safer handling and reduced total ownership costs with the proposed electric systems. Constant tension/heave compensation systems and pendulation control impose less shock on handling equipment and offboard vehicles (e.g. RIB's, Remote Minehunting Systems, ORCA semisubmersibles, and oceanographic research & exploration devices. Potential commercial applications include subsea exploration, oceanographic research, undersea mining, oil & gas exploration and multi-mission small boat handling for diving, rescue and related activities).

As the US Navy fleet reduces in size, the requirement for multiple capabilities on remaining ships is increasing. Combined with the requirement to reduce crew compliments, these capabilities are becoming unmanned, increasing the utilization of the ships, while allowing a safer distance from the threat. The use of Unmanned Surface Vehicles (USV), Unmanned Underwater Vehicles (UUV) and other vehicles such as the Remote Minehunting System (RMS) on surface combatant vessels is highly desirable. An Automated Launch and Recovery System (AutoLARS) for these vehicles and for other offboard vehicles is also highly desirable. This handling system would ideally be capable of handling multiple vehicles, requiring no manual intervention for operations, operation in high sea states, and maintaining practicality for a variety of different installations. This Phase II proposal outlines our plan to further the AutoLARS design, build and test a scale AutoLARS model, investigate COTS components for use in AutoLARS production and produce weight, cost and shipalt estimates for the AutoLARS. The AutoLARS concept is a viable solution to the US Navy’s current requirements for automated handling of unmanned vehicles. This system combines off the shelf components (telescopic knuckle boom crane, constant tension winch) and applies new and existing technology and specially designed components (automated tracking device, capture mechanism, crane end effector, tow boom). This combination of off the shelf and specially designed components allows for a high level of automation with proven launch and recovery principles learned from experience.
