 Okay so this is the SEI quadcopter, it's known as the DJI Phantom quadcopter, it's got quite a big lithium ion battery in that gives you a flight time, well maximum flight time is about 25 minutes but with a safety margin that's about 20 and it carries a GoPro camera on the front to allow you to take either videos or stills depending on what you want and it's on a controlled gimbal so you can adjust the angle of the camera in flight to get the shot that you want. The camera's got a wireless connection to a tablet so you can actually see what you're filming as you're flying and actually control what the camera's doing that way as well so that's what we've got in here. So we're working at the Arboretum trust out at Kesson Howard and the task that they'd like us to help with is they've got a database of all their trees that are in the Arboretum, what they haven't actually got is a map to locate where those trees are so as a starting point of completing that survey we've been collecting some high-resolution air photography to stitch together to make a really detailed map of the Arboretum and based on that we can actually go round to the trees that are all tagged to locate where they are on the ground based on the photograph to link the database to actually the location of the trees on the ground in the Arboretum so that's what we've been up to. So you start the motors off, a variety of things so I've already been talking in the EPSRC co-motion project and this to fly the routes that older people use within towns so that we can film the hazards and the issues that they're confronting from above to get a better feel or to be able to communicate those problems maybe to other people. Then there's the option as well of taking off the GoPro and maybe fitting some other kind of sensors on the front to either record different types of pollutants or maybe look at things in different spectrums of light so looking at infrared perhaps or looking at heat from buildings so doing those kind of surveys.
