A summary of the failure experiments

Zhaoliang Zheng

During the blimp WIFI manual control experiment, I noticed some interesting phenomena. Even the following experiments are just some failure examples, I still can learn something from it. Failure experiment 1: The reason the balloon hit the wall was because human operational mistakes. When you...

Python Script to Read Serial Monitor

Parth Agrawal

Motivation – The Arduino IDE can only be used to monitor a single port. Arduino IDE does not allow multiple serial ports to be monitored simultaneously. Serial library can be used to read, write and print to different serial ports. Therefore, different ports can be monitored simultaneously from the...

Approximate Volume of Helium Gas Required for a Given Blimp

Parth Agrawal

To calculate the volume of helium required for neutral buoyancy based on the mass of components and blimp. Assumptions – Temperature is constant. The gas is purely helium The density of surrounding air is constant Atmospheric pressure is constant Derivations Using the equation - ...

Testing of Different Envelope Shapes Using Flapping Technology: Test 2

Pranav Sankar Srinivasan

My initial test of the different blimp envelope shapes resulted in the other balloons that I had bought not having a large enough volume of helium to support the weight of the flapping technology that is needed to enable them to traverse space. This was also true in the case that all 3 small balloon...

Testing Power Consumption of Motors

Ryan Chen

Recently, I have been working on testing the power consumption of motors. For this part of the experiment, I tested the HobbyPower 8520 Motors while paired with AAA batteries. This is working towards the future goal of understanding the maximum, minimum, and average flight times of given blimp syste...
