communicate with the robot using sounds underwater. how does it move around in the water? is it with these propellers that i can see here on either side? yes, there are eight thrusters that are used and it can move it in all six directions. you have got forwards, backwards, left, right, up, down and then you have got roll, pitch and turn. wow, it is pretty manoeuvrable then. yes. all of this technology allows the device to work autonomously, planning its own route to fully scan a structure, with little human intervention. so, the system that we have will continuously explore the unknown areas and see what comes next on the structure, but we can also suggest positions to it. it takes the images from both cameras, stereo cameras, much like how we perceive depth and it can use this data to create a sd model of the structure, under the water. these can be viewed by the engineers and the surveyors
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 re developing underwater robotic solutions to help take the strain. and they ve come up with this the orca autonomous drone. we ve got our scanning sonar, a mechanical scanning sonar, that can see all of these structures and items around the vehicle at quite a long distance. we ve got an acoustic modem. this means that when we don t use the tether, we can communicate with the robot using sounds underwater. and how does it move around in the water, is it with these propellers that i can see here on either side? there are eight thrusters that are used and it can move it in all six directions. you ve got forward,
