Again we define this for both linear translation force and angular moment:įinally, some influences may be in the inertial frame (such as gravity) while some may be attached to the body (such as the vehicle’s propulsion). We also need to know the forces which influence motion of the vehicle. The angular velocity of the rotating body-fixed reference frame is defined as:

The linear velocity in the body-frame of the vehicle is defined as: Therefore we will need variables which represent both the linear and angular velocity of the vehicle. But to describe the motion of a body what we really want to know is how these change over time. In the first post we already discussed the concept of 6 Degrees of Freedom (6DOF), where we want to know 3-D position in addition to 3-D orientation of the vehicle. What variables are necessary to describe motion? There are two questions we should answer: Describing Motionīefore going into any details about equations of motion, we should identify what we are trying to describe. If you aren’t familiar with those, you may want to read the first post in this series. The contents of this post will build on the concepts of multiple reference frames and Euler angles.

The full series will include all of the following posts: This post is the 2nd in a series on modeling and simulation of a quadcopter’s vehicle dynamics. Project link: īesides the visual and aesthetic differences, the 3D printed version is easily upgraded and modular.In this post we will see how we can describe motion of the quadcopter – or any vehicle – as a set of differential equations. The 3D printed version looks a little bit different: Crossfire 3D printable quadcopter.

Besides that, at a small size, quadcopter drones are cheaper and more durable than conventional helicopters due to their mechanical simplicity.īelow you can see a more detailed overview of quadcopter drone parts of a commercially available top-tier drone used for aerial photography:Īlmost everything that is not a motor or an electronic part can be 3D printed. With their small size and maneuverability, these quadcopter drones can be flown indoors as well as outdoors. It’s the most common form of hobby RC drones. What is a quadcopter drone?Ī quadcopter is a multi-rotor helicopter that is lifted and propelled by four rotors and no tail rotor. Just dive into your favourite 3D modeling software, print it out and test it. So let’s say you’ve bought a new camera for your quadcopter drone and you need a new connector. Last but not least, 3D printing utilises the quick development of custom build parts. Besides easier repair, making a DIY drone will give you much more knowledge about the inner workings and mechanics of your flying machine. With 3D printed parts you have an infinite and quick supply of spare parts that will make your pilot training and everyday mishaps easier to handle. This picture describes it perfectly: The Anatomy of a Drone with things that usually break. Why is this important? Well… drones crash and break. Sometimes you can also print the propellers. That said, you can 3D print the frame and the housing structures. What you need to get startedīesides a 3D printer you will need some non-printed parts like the motors to power it, the batteries, some electronics, the sensors, the remote control unit and some basic skills to put everything together. You will learn some basic concepts and we’ll introduce you to several step-by-step guides. It’s a relatively easy endeavor cause the guides are so detailed. This is an introduction to building your own 3D printed quadcopter drone.
