Hannigan's high C, plucked from the frigid air, might be the most beautiful note you'll hear all year. The final scene finds Ophelia calmly walking out into the falling snow. When she sings "you have sun-blasted me," the orchestra shatters into twinkling shards of sound. Sung by the fearless Hannigan, Ophelia divides her story into past, present and future, speaking of a time without music, the inadequacy of language and a transformative love. The text, by Paul Griffiths, adopts all the words (about 480 of them) Shakespeare allotted to Ophelia in Hamlet, shuffled to create a fresh, confident character with cracks of fragility. The synergy between music, words and performers rarely rises to the extraordinary level found here in Danish composer Hans Abrahamsen's 35-minute song cycle, let me tell you, which features soprano Barbara Hannigan with Andris Nelsons conducting the Bavarian Radio Symphony Orchestra. Paak's irrepressible will to celebrate - a spirit bright like summer, and deep like the ocean off Malibu. This is irresistible pastiche, and the glue is Anderson. These lucid grooves owe a debt to Motown especially, bringing Marvin Gaye to mind with grooves at once detail-obsessed in their assemblage and effortless in their flow ("The Waters" features BJ the Chicago Kid, who's breathing new life into the storied label). Rapping, singing drumming and producing, he pulls from the histories of R&B, rap, pop (he even namechecks Hall & Oates) and old surf movies for an ecstatic, immersive toast to the West Coast. This is an auteur's album, with his stamp on every part of it. Dre's G-Funk as they do to Kendrick Lamar's California conscious rap, but they're unmistakably. Paak forged 16 songs that belong as much to Dr. Dre's Compton in 2015, he caught it on his sophomore solo release. If the young rapper made a wave with his buzzed-about features on Dr. Additionally, mission specific sensors can be easily integrated as required.At the start of the year, in the dead of winter, Anderson. These sensors are mostly used for navigation, control and obstable avoidance however they can also be used for mapping above and below the water. Topcat carries a broad selection of on board sensors. Topcat uses long range, low power 900MHz communication for teleoperation, telemetry and safety communications as well as long range 5GHz WiFi for data and video streaming. CommunicationĬommunication is critical for safety and reliability of the system. This connects to all the sensors and provides the interface to the computer, housed in a separate box. Topcat uses a main electronics distribution box which contains power regulators, network switch, USB devices and microcontrollers. A steering system has been added to ensure high maneuvrability of the vessel in all conditions. Topcat is a fully electrical vehicle powered by two Torqeedo Cruise 2 electic outboard and two large Kokam lithium polymer batteries. To this platform we have added a sensor mounting array, an underwater deploying arm, a battery cradle and two neutrally bouyant motor modules, allowing Topcat to operate safely in the open ocean. Topcat is based on the wave adaptive modular vessel (WAM-V) platform developed by Marine Advanced Research.
These systems allow Topcat to autonomously plan and execute given tasks such as mapping a selected area.
On top of this backbone we have developed multiple algorithms including object recognition and classification, mission planning, navigation and control systems.

ROS is a collection of open source software libraries and tools which enable rapid development of robot software infrastructure. The software which runs Topcat is based on the Robot Operating System (ROS). Our user interface consists of a base control station which relays system information and safety data to the mission supervisor as well as a web based data interface which allows users to access and visualise only the data relevant to them. Developing a system which both provides sufficient information for systems analysis while allowing non technical researchers to easily view data has been a focus for us. Additional sensors can be attached via the underwater deployer to perform specific tasks such as sea bed mapping or environmental surveying.Ī key part of developing unmanned vehicles is ensuring an easy to use and reliable user interface. The vessel is currently capable of mapping and monitoring tasks using the onboard Lidar and Radar systems. The vessel uses the suspension system on the WAM-V platform to provide a stable base for the sensor suite and power systems.įive metres long with a cruising speed of around 4 knots (8 km/h) and a cruise endurance close to 5 hours, TopCat is well suited to monitoring tasks in hostile conditions or protected areas. TopCat is an electrically powered autonomous surface vessel that carries a range of advanced sensing equipment.
