AERIAL IMAGING AND SYSTEMS ENGINEERING PLANNING Name: DOCUMENT Engineer Your World Weight = 1 DIRECTIONS: This document is also in our Google Drive Folder, Engineer Your World (EYW), in a subfolder called Aerial Imaging, if you want to fill it out electronically. Fill out the following. Each blank is one point. Team Members (need three people): DIRECTIONS: Use the word bank below to fill in the missing blanks. Do any problems following team disaster aerial imaging subsystems emergency capstone billion There are over one people living in the world that are unreachable by roads. This is an immediate problem, especially for populations living in -prone regions. An aerial system will be developed to survey an area where disaster aid and relief supplies are to be delivered to populations that would otherwise remain isolated. The aerial imaging unit is our EYW project which means it is our culminating project of the year. The project is really challenging you in three areas: 1) the specific engineering challenge of designing and building an device that can be dropped in a controlled descent, take good quality pictures at programmed intervals, and signal its landing. 2) designing and programming several simpler engineering to work together to accomplish the more complicated and coordinated task described above, 3) working effectively in a of three to accomplish a complicated task. 1

These are: AERIAL IMAGING SYSTEM 1) MOVEMENT. Control the vertical of the device to the ground. 2) IMAGING. Take automatically at programmed intervals 3) DETECTION. Constantly monitor the of the device above the ground and signal when it lands. 1) MOVEMENT. To control the downward motion of your aerial imaging device you have to consider three functions of the vertical descent subsystem. A) Your device cannot fall too because it might run out of. It cannot fall too fast because you might not have enough time to take enough, they might come out and fuzzy, or the device itself may be upon landing because of the high impact. B) You also have to connect this subsystem to the other subsystems so that you can the falling while the picture-taking is happening, like an orchestra conductor. C) Finally, you have to make sure your device doesn t uncontrollably in circles and is stable as it descends. The two main reasons it might want to do this is because of weather conditions or frankly, because of engineering design. 2

To control the imaging you have to think about how A) you will start taking at the right time. B) take the images at intervals. D) taking pictures when the camera lands. 3) DETECTION. To control the processes already described, you need to know how the aerial imaging device is above the ground. A device that can be used to do this is called an or barometer. This device must inform your device s center the device s vertical location because this is how your aerial imaging system knows when to start pictures, when to stop, and when to signal that it has landed in order to be off and picked up. 4) MISCELLANEA. Other design considerations include your electronic devices, like your camera lens, from possible inclement weather and from impact damages, and how your electronics will be to your aerial device. You also need to think about what kind of you will be emitting once it lands. Will it be so it can be seen or will it be so it can be heard or both. 3

In remote or dangerous areas and in the developing world, you might not have an experienced drone on hand or a drone outfitted with an aerial imaging system. While we will be allowing drones to get our device up in the air and for controlled descent, another solution that is often employed is to drop the aerial imaging system out of an, deploy a to slow the vertical descent, activate the system electronics, and then find the device on the ground once it lands later using some kind locator. We will have this option available to you if you don t use a drone. We will drop the aerial imaging system from the top of the football. The issue with this kind of system, which is the opposite of an active system, is that if the device is subject to weather conditions, it may miss the target it is supposed to be photographing, where supposedly the disaster happened, for example. In life situations, really high- cameras would have to be used because the useful photographs are the ones taken right when the aerial imaging device is, when the plane is still relatively above the ground and far away from the targeted viewing area. 4
FLOW DIAGRAM OF AERIAL IMAGING DEVICE. DIRECTIONS: In the space below, create a flow diagram of your aerial imaging device. Use boxes and arrows to show the flow. The first boxes will be to begin your descent to the ground and activate your subsystems and the final box will be turning off your subsystems and signaling that you have landed. Have at least 12 boxes in total with the steps labeled. EXAMPLE of a flowchart: 5
