- [00:00:00.630]Hello, my name is Daniel Rico and I'm a master's student
- [00:00:03.630]in the Department of Computer Science and Engineering
- [00:00:05.710]conducting research in the Nebraska intelligent mobile
- [00:00:08.230]unmanned systems or Nimbus laboratory.
- [00:00:11.020]Under Dr. Carrick Detweiler of the computer science and
- [00:00:14.318]engineering department, and Dr. Muniz area of the biological
- [00:00:17.560]systems and engineering department,
- [00:00:18.510]unmanned aerial vehicles, or better known as you UAVs have
- [00:00:21.460]found their way into the agricultural sector in recent
- [00:00:23.760]years, attempting to collect data.
- [00:00:26.110]Typical UAVs, like this one,
- [00:00:28.940]are heavily limited in their flight times,
- [00:00:30.710]usually between 15 and 30 minutes due to their reliance on
- [00:00:34.560]lightweight lithium polymer batteries.
- [00:00:36.940]Our research has to do with engineering a system that
- [00:00:39.370]addresses this limit, and at the same time have
- [00:00:41.910]the ability to collect more data.
- [00:00:44.150]We're developing a tethered aircraft unmanned system,
- [00:00:47.130]which utilizes a battery bank and power transmission over
- [00:00:50.470]a tether to power the UAV eliminating the reliance on
- [00:00:53.420]small onboard batteries and therefore increasing
- [00:00:56.320]continuous flight times.
- [00:00:58.030]We have taken our system to the field for experimentation
- [00:01:00.630]and successfully flown for six continuous hours
- [00:01:03.251]at an altitude of 50 feet above ground level.
- [00:01:06.110]This flight time is on the order of a 12 fold increase
- [00:01:08.850]to typical UAVs.
- [00:01:10.590]The novelty in our work comes from leveraging the physical
- [00:01:13.530]presence of the power tether and integrating an array of
- [00:01:16.470]sensors along it, as can be seen in this concept diagram.
- [00:01:20.450]In doing this, we increase sensor data collection
- [00:01:23.140]in space through time.
- [00:01:25.491]The graph to my right shows the collected temperature data
- [00:01:28.840]at sunset from the array of sensors,
- [00:01:31.370]we can see a clear trend downward indicating the temperature
- [00:01:34.340]is decreasing across the array due to the sun setting.
- [00:01:37.790]Eventually, as our research matures, we would like the data
- [00:01:41.160]we acquire with our system to help agricultural
- [00:01:43.990]decision makers make more well informed decisions.
- [00:01:47.510]If we're able to do this we envision our system will become
- [00:01:50.560]a commonplace instrument in the sector.
- [00:01:53.030]Finally, I would like to thank the Doherty Water for Food
- [00:01:55.700]Global Institute for the student support funding
- [00:01:58.290]provided over the last academic year.
- [00:02:00.630]Thank you.
