If you’re really interested in drone coding, this information will be a great starting point. Keep reading for more!
Up until now, one of the main challenges faced by people that are in drone programming was the lack of structured and comprehensive learning resources. While this guide will be considerably easier for people that are well versed with the basics of programming, with a little effort, even beginners can hack it.
The truth is that drone programming isn’t as difficult as people take it to be. With the right resources to guide you in the right direction, you’ll be in a better position to create code for your drone in no time! There are 3 main ways you can program your drone; from scratch, through one for all programs, and using a DIY drone kit.
Yes, it’s possible to program a drone from scratch. You, however, need to note that only a few drone models are programmable. So, if you’re an expert at coding, you can create a program for your device. Even though drones are already equipped with basic programs to make it easy for you to control them via an app or remote device, programming gives you a more unique and effective way of controlling them.
This is where you create one program and pattern for a group of drones. This mode of programming is especially used in sky shows—eg. in China. In fact, in September 2020, China broke the Trusted Source3,051 drones create spectacular record-breaking light show in China | Guinness World Records At 3:45:39 am on September 20 2020, 3,051 Unmanned Aerial Vehicles took to the skies to break the record for the most Unmanned Aerial Vehicles (UAVs) airborne simultaneously. www.guinnessworldrecords.com for the biggest drone light show. There were a total of 3,051 drones at the show, captivating millions of people around the world.
Now, in this scenario, it’s difficult for 3,051 people to control each of the drones, which is where a one for all program comes into play. The program causes all the drones to synchronize their movements and move in unison.
Programmable drones are almost exclusively sold for educational purposes or to enthusiasts that are passionate about drone programming. DIY drone kits are then used to practice drone coding and allow you to program your drone from scratch. They also come in handy for people looking to develop their own drone app.
Programming languages help you communicate with drones. This is the only way you can tell your device what to do, based on the program that you create. There are two main programming layers; high-level programming and low-level programming.
Check out how they differ from one another and how you can use them on your drone below!
Drones contain both hardware and software. High-level programming deals with the drone’s applications or software.
Think of the drone as a complete unit, and the only thing missing is an app that you can use to help you control the device as you wish. For instance, you can use high-level programming to fly the drone to a particular altitude or to supply it with information such as GPS coordinates so that it can automatically fly to the set location. High-level programming also helps to decrease or increase the flying rate.
You should note that high-level programming collaborates with the drone’s firmware to interpret the commands and perform the intended action. For instance, if you use the flight controller to fly the drone at a particular altitude, the app communicates with the drone’s software. The firmware then communicates with the hardware and flies the drone at the set elevation. This is why high-level programmers don’t really focus on the firmware technicalities and how the software will implement the program.
Here’s another instance, assuming you’d like your drone to interpret GPS coordinates so that it can fly in the direction that you command it via the app. In this case, the main aim of high-level programming is to communicate this information with the firmware, which then instructs the hardware and moves the drone.
Compared to low-level programming, high-level programming is significantly easier to understand, which is why it’s more available. It also uses popular programming languages such as Python and Java, although Python is more user-friendly and highly preferred by beginners and basic programmers.
Most of the time, high-level programming focuses on APIs (Application Programming Interfaces) as opposed to natural language.
Low-level programming focuses on the drone’s firmware, which are the components that coordinate and communicate with the hardware that the drone runs on. This hardware includes ESC, propellers, engines, batteries, & motors and allows the drone to use all the components to conduct basic and fundamental functions. For instance, if the drone is commanded to execute a level but safe flight, its firmware will assess the IMUs (Inertial Measurement Unit) data to identify the amount of electricity that should be delivered to the propellers and motors. This then allows the drone to stabilize itself while the firmware coordinates with the hardware mid-flight.
For low-level programming, you need to be well versed with C and C++ as they’re the principal programming languages used. While low-level programming languages are often difficult to understand, if you already know the basic programming languages, this shouldn’t be a problem. The best part is that once you also get the hang of it, you’ll have a ton of fun programming the individual aspects of the drone’s firmware and hardware.
Once you learn the basic UAV programming languages, you then need to get a programmable drone. These drones already have an SDK (software development kit) or API (application programming interface) in the package, and most of them already come installed with the low-level programming or the firmware required to control the drone’s hardware. This means that the only thing you’ll have to do is use high-level programming to develop an app that you can use to control the drone and command it to perform specialized functions.
Since not all drones are programmable, it’s important that you get one that’s compatible with your preferred programming language like Python. You could also get an SDK that’s accompanied by a drone. This way, you can create your own drone app without having to use a programming language, as long as the SDK is fully equipped with everything you need to create the application. You’ll, however, still use your programming knowledge to develop it.
Here’s everything you need to program your drone.
DJI drones are undoubtedly one of the most popular models in the market currently. If you already have one of their models, you can use their APIs and SDKs to develop your own iOS and android app, specifically designed for a DJI drone. If, on the other hand, you’re still looking for the perfect drone, the DJI Mini SE is one of the best based on multiple reviews. It’s highly affordable and is one of the top drones under $500. This model weighs less than 0.55 pounds and has the same weight as an average smartphone. You can use it in the US or Canada without having to register it, and it has a powerful capture on-the-go camera, making it perfect for people that primarily use their drones to capture moments. The DJI Mini SE will offer you up to half an hour of flight time which is longer than other similar models. It also has upgraded wind resistance, and with the DJI Fly app, you can access multiple creator templates to edit your photos and videos.
One of the main reasons why DJI SDKs are highly preferred is because they’re flexible and offer great features such as remote access to the camera’s websites, barrier evasion, high and low-level flight controllers, and a live video feed that allows you to leverage the amazing camera capabilities of your drone.
The only major downside of the DJI SDKs is that you have to pay for the APIs. You can, however, contact DJI to get your hands on an API or SDK that’s specific to your drone, including models such as Mavic, Spark, Phantom series, etc. This will give you a great opportunity to sharpen your programming skills as DJI SDKs have rich features.
Drone kit is one of the best programmable drone kits available and is typically an SDK that you can download on your android smartphone. As long as you’re knowledgeable on high-level programming, you can easily use it to create an android application to control your drone. The best part about DroneKit is that it’s open-source and free. It also comes fully equipped with the basic features required to control a drone, including autonomous features such as intelligent flight path panning. You can use DroneKit to create a different code other than the one other programmers use since it’s open source. The only major downside is that you’ll not have any customer support and have to figure things out on your own.
