[00:00:02.070]Hi, this is Bryan Melendez. I'm a student, I'm a mechanical
[00:00:06.300]engineering student of the University of Puerto Rico in Mayaguez.
[00:00:11.370]Uh, I'm doing research, in
[00:00:13.860]the University of Nebraska Lincoln and the Nimbus lab,
[00:00:18.300]Nebraska Intelligent MoBile Unmanned System (NIMBUS) Lab
[00:00:23.130].
[00:00:25.920]I'm going to be discussing my research project,
[00:00:28.590]which is titled Novel Multi-rotor Deployment Mechanism
[00:00:32.370]Design for a Carrier Aircraft.
[00:00:34.470]So this is my poster and I'm going to be going through it as I talk.
[00:00:40.050]Uh, so first the motivation of this research
[00:00:43.890]because of the lack of UAV research and deployment, uh,
[00:00:48.510]the reason this research is being done, about, carrier drone deploying,
[00:00:53.040]mini drones act as the mothership
[00:00:57.360]So this security around the deployment mechanism and,
[00:01:02.790]previous work in the Nimbus lab has been done, uh,
[00:01:06.540]with a pin-pulling mechanism. But this, uh,
[00:01:10.080]this mechanism is in,
[00:01:12.840]it isn't as effective as
[00:01:17.430]get, like,
[00:01:18.690]we want a better deployment mechanism,
[00:01:22.470]and this is what I'm trying to prove where my research,
[00:01:26.730]also, we want to figure out how many combinations of drone we can carry with the
[00:01:31.470]mothership we're going to be using. a little bit of the background,
[00:01:35.850]Fixed-wing [inaudible], uh, have good range and,
[00:01:40.860]but we're going to be using a multi-rotor as the carrier
[00:01:45.570]and also, multi-rotor deployable drones.
[00:01:49.590]So now the reason for this
[00:01:54.150]is that we want better payload capacity,
[00:01:56.130]and drones have better Creole capacity than fixed-wing aircraft,
[00:02:01.380]uh, fixed [inaudible].
[00:02:06.780]deployment mechanism for [inaudible], uh,
[00:02:11.250]it's really scarce due to complexity of weight and symmetric constraints,
[00:02:15.930]uh,
[00:02:17.190]and there's limited amount of carrier drones.
[00:02:21.300]So in the future, we will want to expand on this and,
[00:02:25.800]and get a better carrier mothership,
[00:02:28.020]so it can carry more than 20 kilograms and more
[00:02:32.700]drones. And that way we can also improve, uh,
[00:02:36.030]frames of deployment mechanism and the deployment mechanisms.
[00:02:40.110]So in this research and we will use. And
[00:02:45.010]before that, in this photo, we see the deployment.
[00:02:47.790]I got to think concept previously the belt,
[00:02:51.390]and now in the,
[00:02:52.860]I'm going to go through the process of the new deployment mechanism.
[00:02:56.820]So we collected data shown in table 1. when we can
[00:03:01.660]see the weight of the drones batteries and the payload. So, uh,
[00:03:06.130]the combination
[00:03:10.660]of we calculated the combination of the payload,
[00:03:14.050]the weight of the battery and the weight of the drone.
[00:03:16.600]So we can know how much our, uh, carrier drone is.
[00:03:21.520]Uh, it could carry in different combinations,
[00:03:25.240]like those are the results we want. So, uh,
[00:03:28.870]so we develop a system were have,
[00:03:33.130]or carry around this, uh, DJI Matrice,
[00:03:35.620]600 pro or M600 as the caarrier drone. And we have two,
[00:03:40.360]uh, commercial off the shelf (COTS), drones know as flame wheels.
[00:03:44.980]So the ones, uh, that appear here,
[00:03:48.970]this one in the meadow, it's a,
[00:03:51.070]a F550,
[00:03:54.100]and this one's are F330. So those are deployable.
[00:03:59.170]Uh, so based on this, uh,
[00:04:04.150]concept of figure two is the concept use with the pin-pulling
[00:04:09.130]mechanism in the previous research, and we want to expand on this.
[00:04:13.180]So the way we thought in the odd process on this new,
[00:04:17.800]the sign shown in figure 3., is that we have, um, better.
[00:04:22.820]So we have better understanding
[00:04:26.530]of the alignment of the drones and we have symmetry.
[00:04:29.530]So the important thing is that this, uh,
[00:04:32.680]old frame with the drawings and the appointment mechanism,
[00:04:36.010]it's gotta be or to the carrier drone. So,
[00:04:40.720].
[00:04:45.070]it's gonna retain her. And then like,
[00:04:48.220]this is the solenoid drop mechanism. So we improve on the pin-pulling mechanism,
[00:04:52.990]So solenoid drop mechanism. So the solenoid, uh,
[00:04:57.850]uses a piston to push out the drone and it's activated
[00:05:02.470]manually by a ground station. So we're going to have a ground station,
[00:05:07.150]and we're going to indicate when we want to drop the drops and which drones we
[00:05:11.380]want to drop. This concept was made, uh, for a maximum of six drones,
[00:05:15.580]because the maximum weight the M 600 pro can carry,
[00:05:20.740]is a maximum 10 kilograms. So we don't want to exceed, uh,
[00:05:26.260]we don't want to exceed more than 10 kilograms, like, uh,
[00:05:31.230]the capacity is 20 pounds, and we can't go pass that,
[00:05:35.890]uh, that pound limit. So here we can see the solenoid drop mechanism.
[00:05:40.930]So for our results,
[00:05:45.370].
[00:05:46.570]basically, we use the weights, and out of,
[00:05:51.610]all the weights we got and all the data, we figured that,
[00:05:56.620]uh, best,
[00:05:58.490]best is only four combinations we can do with this carrier drone.
[00:06:03.200]Uh, so the maximum weight they can take is 20 pounds.
[00:06:08.240]this means it's limited to four to six drones and,
[00:06:13.970]and even three to six drones. And as we see on the results now,
[00:06:18.200]so no more than two, uh, F550, like we, we,
[00:06:23.390]when, when it's combined with F330 at our could be three,
[00:06:28.040]F550, because that's 9 kilograms,
[00:06:31.130]or it needs to be no more than 2, 550 with
[00:06:35.840]other combinations of F330. So in our results,
[00:06:38.780]we got four different combinations. Uh, six, I have three F330,
[00:06:43.370]uh, which [inaudible] for one, uh,
[00:06:48.230]after three F330 versus [inaudible]. And, uh,
[00:06:52.580]in my opinion, the best combo, eh,
[00:06:55.240]for a strong swarm deployment is three F330 uh,
[00:06:58.400]after journeys and two, F550. So, yeah,
[00:07:03.530]and the, to include, uh,
[00:07:07.780]so this multi-rotor mechanisms are
[00:07:12.160]limited for to the constraints of the carrier aircraft.
[00:07:16.750]So as the carrier aircraft
[00:07:21.700]can carry up to 30 kilograms, we can,
[00:07:24.610]we need to adjust our system to that carrier aircraft.
[00:07:29.020]The system is not universal. This is for our carrier aircraft.
[00:07:34.000].
[00:07:37.720]the novel solenoid deployment mechanism system helps
[00:07:42.700]make, uh, your own drops and consistent, uh,
[00:07:47.500]for future work though,
[00:07:49.930]improvements need to be made to the deployment mechanisms.
[00:07:53.010]This is compatible with these drones, for future work.
[00:07:56.740].
[00:08:00.670]deploying more drones and, increasing the carrier UAV weight capacity is the goal.
[00:08:04.600]this concludes my presentation.
