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
and it can move it in all six directions, coming up forward, backwards, left, right, up, down, then you have role, pits, and turn. down, then you have role, pits, and turn- and turn. oh, well, so it is re and turn. oh, well, so it is pretty manoeuvrable - and turn. oh, well, so it is| pretty manoeuvrable then? and turn. oh, well, so it is - pretty manoeuvrable then? yes. all this technology allows it to move autonomously, planning is en route to fully scan a structure with little human intervention. 50 structure with little human intervention. structure with little human intervention. so the system that we have intervention. so the system that we have will intervention. so the system l that we have will continuously explore the unknown areas to see what what comes next on the structure, but we can also suggest positions to which. it takes the images from both cameras, the stereo camera, much like how we perceive depth, and it can use this data do perceive a 3 d model of the struc
