Objective
Objective
Design a drone that is lightweight but has a maximum deflection under 0.2N of 100 micrometers.
Also to design it so it can carry as much weight as possible
Design Process
Design Process
Our design consisted of multiple parts including the chassis, a holder for the PCB and a board that would hold the weight.
Our chassis was the main part of the assembly and I came up with a design that included using hollow cylinders as the arms as it would limit deflection but also decrease total volume.
We also did a FEA analysis of multiple types of chassis arms, ultimately deciding that an outer diameter of 5mm and inner diameter of 3mm was a good trade off for weight versus strength.

Drawings
I did the designing for this project as my groupmates did the engineering drawings including using GD&T, here is some of their work.
Assembling
Assembling
We soldered the motors to the PCB by following a diagram and snapped the parts of the drone together. We decided to use a rubber band to mount the battery on the bottom.
During test flights our drone was able to carry 15 grams, a little under its body weight.
Test Flight And Final Thoughts
Test Flight And Final Thoughts
Some things I learned in this project was how precise ducts need to be in order for them to work well and how FEA can be an amazing tool for gauging the strength of your component.
