Joint Institute is a school of engineering located in Minghang District, Shanghai. Itwas founded in 2006 by the University of Michigan and Shanghai Jiao TongUniversity (Both are globally highly ranked in engineering). The school offerstwo undergraduate programs: Electrical and Computer Engineering and MechanicalEngineering. It provides students with an opportunity like no other of studyingin an English environment with other top students who are enthusiastic aboutengineering.
In earthquake of high magnitude, constructions get seriously destroyed and structures become unstable. Inacceptable areas form where rescuers cannot enter. Victims can be stuck in those areas for days without water and medicine. As a result, they have little chance of survival. To solve that problem, we design a rescuer blimp which has the following functions. First, it can carry water and medicines to the victims. Second, it can film videos day and night and send the video stream back to the rescue terminal, providing rescuers with more information of the disaster scene. Finally, it can be used by victims to convey their needs to the rescue terminal. To fulfill our design, we set 6 tasks for out project. First, we insert two coreless motors and an arduino board under a helium-filled balloon on a wooden base. Then we fix a wireless camera on the base together with some LED lights for night filming. After that we construct an application on Android platform and use Bluetooth to realize the function of remote communication. Then we test our first prototype and make some improvements. Tests include speed test, obstruction avoidance test and real scene test. Up to now, all the functions have been validated.

Step 1: Board Cut
Find or buy a wooden board and cut it into 10cm*35cm.
Step 2: Draw Concept Diagram
Design the blimp.
Step 3: L298N Motor Driver
Buy L298N motor driver and attach it to the board according to the diagram.
Step 4: Wireless Camera.
Buy a wireless camera of wifi host, and attach it on the board.
Step 5: Coreless Motors
Attach two coreless motors on the board according to the diagram.
Step 6: LED Light
Attach superbright LED light onto the board so that the camera can work at night.
Step 7: Distance Sensor
Attach two distance sensor onto the board.
Step 8: Controlling
We use arduino bluno nano as the controll system because it is very light and more powerful than arduino uno.
Step 9: Finish Board
The board is finished, it should look like this.
Step 10: Balloon
Attach a 36 inch balloon onto the board, put helium in the balloon. It should now be able to float.
Step 11: Programming
Download the software of arduino bluno nano from DFrobot. Everything is controlled by Arduino nano bluno.
Step 12: Testing
Testing the blimp, adjust parameters and make improvement.
