outside africa, where it s most common. first identified in monkeys, the disease typically spreads through close contact. coming up shortly on bbc news newswatch. but first here s click. no, this isn t some kind of sea monster. but an autonomous machine that aims perhaps to make working and see that little bit safer. with an ever growing demand for renewable and sustainable energy sources, the infrastructure that provides that energy is becoming increasingly critical. now, at present, those facilities are often maintained by human divers working in challenging and hazardous conditions. but here at heriot watt university they are developing underwater robotic solutions to help take the strain. and if come up with this, the walker autonomous drone. ~ ., this, the walker autonomous drone. ., ., drone. we ve got our scanning sauna, drone. we ve got our scanning sauna. a drone. we ve got our scanning sauna, a mechanical drone. we ve got our scanning sauna, a mechanical sc
so the due main sensor technologies that we have our active soon as using for tracking seals, primarily, so they don t make noise underwater, so they send out a very, very high frequency ping which is too loud for the animals to hear and be disturbed by, and they listen for the echo, and they can build up an image of exactly where the animals are around the turbine. on the other sensor that we ve got is underneath this protective housing here, which is the passive hyper queens beach are listening to the sounds the animals make and we use those to pick up the sounds of porpoises and dolphins. jahh porpoises and dolphins. john o groats. porpoises and dolphins. john o groats. it porpoises and dolphins. john o groats, it is porpoises and dolphins. john o groats, it is here - porpoises and dolphins. john o groats, it is here the - o groats, it is here the monitor will be sung underwater and installed on the seabed next to the turbine. it s 5am, next to the turbine. it s sam, the ship
