Micro Class

HR Divider

Airgineers Micro class requires students to design and build their own Micro Drone to compete in a number of different challenges. The manufacturing techniques that students choose to use is completely up to them – it could be 3D printed, laser cut, handmade or something else entirely!

Pilots will need to control their drone from First Person View (FPV) which means they will wear goggles that have a video feed directly from their drone – to the pilot, it feels like they are sat right in the cockpit.

What is a Micro Drone?

HR Divider

A Micro Drone is a small quad-copter that is designed for indoor use. A Micro Drone is made up from a number of key components:


Micro Class Drone
  1. Camera: A small video camera that is used to see the First Person View (FPV), as if the pilot was onboard the drone
  2. Propeller: 4 propellers are used to provide thrust which moves the drone
  3. Video Transmitter Antenna: Used by the Video Transmitter to broadcast a 5.8GHz video signal to the FPV goggles
  4. Motor: 4 motors are used and are connected directly to each of the propellers
  5. Electronic Speed Controller (ESC): The ESC takes a signal from the Flight Controller and converts it to voltage to control the speed of the motors
  6. Flight Controller (FC): The brain of the drone. It has accelerometer and gyroscope sensors that detect the movement of the drone. This data is combined with the inputs from the pilot and the flight controller which will then work out what signals need to be sent to each motor
  7. Video Transmitter (VTX): Takes a signal from the camera and converts it to a suitable 5.8GHz signal to send to the FPV goggles worn by the pilot
  8. Receiver (RX): Receives data from the pilot's transmitter using the 2.4GHz frequency. This data is then passed to the flight controller for processing

The Airgineers Micro Class Challenges

HR Divider

For the inaugural 2017/18 competition, the Micro Class is made up of two independent challenges – Head to Head and Capture the Flag.

Head to Head is a race between two teams around a course that is marked out by a series of gates. The team who finishes the required number of laps fastest is the winner.

Capture The Flag is a team game where two teams work together to try to capture more flags than their opponent. Teams can also get bonus points for landing their drones on the landing pads before the match ends.

What equipment do you need to take part?

Free CAD Software from Autodesk

HR Divider

AutoDesk
AutoDesk Fusion 360

Autodesk have been producing CAD software for 35 years and have products to help designers in almost any field realise their ideas. Fusion 360 is the latest CAD software for creating 3D prototypes and best of all...it’s free for schools to use!

The team at Airgineers have worked with the experts at Autodesk to produce instructional videos to help you learn your way around Fusion 360 and create your own drone chassis. You can also download CAD models of the other parts used on the drone such as the motors, flight controllers and propellers which means you can make sure that your design is right before you manufacture it.

To obtain Autodesk 360, visit Autodesk here.



Airgineers Fusion 360 CAD Tutorials

HR Divider

Autodesk have created a series of videos tutorials to guide you through the process of designing a drone in Fusion 360. The tutorials are aimed at complete novices, so even if you have never used Fusion 360 you will be able to follow the step-by-step guides and learn all the steps needed to then go on and design your own micro drone frame.

As well as learning how to design in Fusion 360, the videos will also show you how to estimate the weight of your frame before printing, simulate the stresses and loads to find weak points in the design and add other components like the motors and flight controller. You will also be able to add decals to the design, export high-quality renders and create animations.

Please see www.autodesk.co.uk/airgineers for more information.

Example Frame

This example frame is an STL file compatible with almost any 3D printer. It gives you an opportunity to practice flying a Micro Class drone before you design your own frame for the competition. Please note – this example does not have a mounting point for an FPV camera. Please download the file from here.

CAD Assets

This zip files contain Fusion 360 and generic STEP CAD files for the motors, flight controller, propellers and battery. You can import these in to your CAD designs to check that the parts are going to fit once it is printed. Please find the files below.


Micro Class Racing Gate

Laser cut your own Micro Class racing gates and make your own courses to practice on. The download includes both DXF and DTD (2D Design) files which can be used with most laser cutters and instructions for assembly.

The gates are designed to be cut from a 5mm thick sheet of 600x400mm acrylic but other sheet materials can be used. You will also need some M4 machine screws and nyloc nuts or for these that have VEX Robotics kit, the standard VEX 8-32 screws and nyloc nuts can also be used.

Keeping a Flight Log

Students are encouraged to document their Airgineers journey as they would with any school project. One way of doing this is through a digital notebook such as Kapture8

What is Kapture8

Kapture8 is an online platform and mobile app that allows students to record their learning journeys and create portfolios all in one place. Teachers can collaborate, monitor and assess by using the quick and innovative review features.

Why use a digital notebook?
