QUESTIONS & ANSWERS

Before the project is completed

QUESTION 1 : WHAT WILL IT DO?

  • We have all heard or even tried what I want to make byself! My idea is to build a drone. A drone like a drone. In a limited time, however, it will not be possible to implement all the functionalities, so the minimum requirements for a drone are to be able to rise above the ground with the help of a remote control.

QUESTION 2 : WHO HAS DONE WHAT BEFOREHAND?

  • Since I plan to make only the drone part, not including the remote control, I started reading the data sheet on how the flight controller board by Beecore Flysky F3 works to better understand what electronic components are integrated and how the drone communicates with the remote control.
  • A high level and good example of a drone project is a Fab Academy 2015 student - Daniele Ingrassia.
  • Also a good example of a drone project is a Fab Academy 2015 student - Mattia Ciurnelli.

QUESTION 3 : WHAT WILL YOU DESIGN?

  • In the "Molding & Casting" week I thought that I could make my own design for a drone propeller. Click on the button and look for my effort.

    • For practice it was good to try designing it but when I searched for more information about "What are the best propellers for drones?" or "How to choose propellers for drones?" etc. I received many scientific articles and I understood that this is so complicated because it is related to Aerodynamics. My conclusion - now I know that on the Internet are ready-made models and I will just import it in my design or just buy ready-made propellers.
  • I will design electronics - flight controller and power supply PCB.
  • I will develop CAD - frame, landing gears and some connectors.

QUESTION 4 and 8: WHAT MATERIALS, COMPONENTS & PROCESSES WILL BE USED?

  • It is planned to use plywood for frame production by laser cutting, but with the development potential of milling using carbon fiber, which is considered to be a very suitable material for drones, as they are very durable and at the same time light weight. Also for stable landing it is planned to use 3D printed landing gears, I have not yet decided whether it will be PLA or SLA 3D printing technology by Ultimaker S3 or Formlabs "Form3". Other connectors will also be needed, they are planned to be made in laser cutting and/or 3D technology. It is also planned to use four brushless motors and electronic speed controllers (ESC) for the movement, which are needed to control the speed and direction of the motors. It is also planned to use Li-ion batteries with at least 7.4V voltage (this is the minimum required for ESC operation) and a maximum of 14.8V for energy supply. Of course, also a battery-compatible battery holder. It is also planned to be used for remote controlling laboratory equipment - remote controller Flysky FS-IA6 and receiver FS-IA6. Of the electronic components to be used microcontroller ATtiny 3216 in PCB which is planned to be made by milling machine "MonoFab SRM-20", accelerometer & gyroscope module by Adafruit, while the power supply PCB core will be screws terminals. A more detailed description of the materials and components used is available in the "Bill of materials" section.

QUESTION 5 and 6: WHERE WILL THEY COME FROM & HOW MUCH WILL THEY COST?

QUESTION 7 : WHAT PARTS AND SYSTEMS WILL BE MADE?

  • The drone embedded microcontroller interface and programming will be self-manufactured and integrated into the flight controller board. The drone is intended to be operated outdoors without the possibility of a connection point, therefore it is planned to develop a power supply board with the integration of batteries of the required capacity. System integration and packaging is expected to be achieved by developing optimal 2D, 3D designs for the frame and fittings.

QUESTION 9 : WHAT QUESTIONS NEED TO BE ANSWERED?




QUESTION 10 : HOW WILL IT BE EVALUATED?

  • Of course, I would like to say that the biggest achievement will be if my drone behaves like a real drone, but critically - at least the drone was able to take off and land under the control of a remote controller. The next stage of success would be the drone's ability to balance using the built-in sensor and the developed algorithm. No less important is the evaluation of the integration and packaging of the whole system, so the design must be attractive and suitable for the operation of the drone. And the part of the documentation should be so ready that anyone can start their journey to making a homemade drone using my portfolio.
