Sea Machines Robotics of Cambridge, Mass. announced the release of its Autonomous Control System (ACS), an advanced vessel control system which converts manually piloted hulls to self-piloted Unmanned Surface Vessels (USVs). It is designed to be integrated into company-developed Sea Machine USVs or other commercial production hulls. The ACS allows for seamless transition between unmanned and manned operations and can be integrated into most OEM vessels, including workboats, pleasure craft, launches, fishing vessels, survey boats, tugs and more.
