Make it possible to reconnoiter at all regions. 1. Design Development Make it possible to reconnoiter at all regions. + ▶ Recon in the air ▶ Recon on the ground ▶ Recon on the water surface And second is combination of these two concepts. One can reconnoiter in the air and on the ground, and the other can reconnoiter on the water surface. Even if we choose any case, our objective is “make it possible to reconnoiter at all regions. Team Zeta-Go ; Beat Alpha-Go

Make it possible to reconnoiter at all regions. 1. Design Development Make it possible to reconnoiter at all regions. This is our prototype design which we drew it in 3d CAD. We featured it that in the wheel there are going to be propellers and below that body frame we will put Some boat shape to float by itself. And the buoyoncy of the these tires ,it will help the body frame balance and back of boat, cause we need to get a thrust Power so there will be screw shape. It was hard to draw the screw, so I put the propeller shape by the way. We estimated our prototype approximately, so Feature can be changeable, this is our first draft. Team Zeta-Go ; Beat Alpha-Go

1. Design Development - Free Body Diagram - Momentum Equation W L =4T - Free Body Diagram : thrust (4 motors) ＊ - Momentum Equation We also calculated some lifting forces and the point in this Free Body Diagram, summation of thrust must bigger than the weight. And we are going to use the quad-copter, each thrust power that motor should make can be reduced, divided by four. Four times thrust power must be bigger than the weight. And also we calculated some fluid dynamics simply and momentum equation can be expressed like this. When we neglect the point 2 and 3, We can obtain this equation. It only depends on position line 1 and 4 and its velocity, and law and flow rates of the air. Then we can conclude that the mass must be lower than the 3.77kg. It’s all related to the force dynamics. : Entrance velocity ＊ : Exit velocity - In conclusion, Team Zeta-Go ; Beat Alpha-Go

2. Final Model 2. Final Model Nowadays we can see that video clips on youtube remote controlling some product like drones and RC Cars and take some videos and uploaded to the site. As our team selected the main machine as drones, we have watched a lot of times on these videos , but as we goes on this project we find that previous drones have a limited flight time about short of 10 min . We consider this problem and thought that how can we improve this flight time Enough to be used broadly, so we get into this problem. Team Zeta-Go ; Beat Alpha-Go

4. Security Regulations ◈ No-fly Zone According to Aviation Law (2015.5.30) 1. Most Seoul, near the DMZ, and other designated area is no-fly zone. 2. A radius of 9.3km area where the central point is nationwide airfield 3. More than 150m altitude in all regions 4. All the region where many people are gathered together in all areas R-73 : Defense-related no-fly zone. We must get a permission to department of Defense or Capital Defense Command. R-75 : In the case of flight restricted area without authorization, 150m or less can watch the flight distance. Team Zeta-Go ; Beat Alpha-Go

4. Security Regulations Team Zeta-Go ; Beat Alpha-Go

Compliances of Drone Operator - Any night flight is not allowed. 4. Security Regulations Compliances of Drone Operator - Operators should always check the drone when it flies. - Any night flight is not allowed. - Do not drop objects during the flight - Do not operate a drone in a drunken condition Team Zeta-Go ; Beat Alpha-Go
