Why Drone Programming Is Important?
There are many reasons why drone programming is an important skill. First, drones offer a very involving yet exciting way to learn to code. Thus it’s an appealingly fast way to learn Python, C++, and other programming languages.
Secondly, drones share technologies with other autonomous vehicles and robots, making drone programming a valuable skill. With the bright future of these industries, expect to be a much sort-after programmer.
Finally, drone programming is a fantastic hobby. Drones have endless applications in today’s life, from delivering a beer to your thirsty friends to military missions.
Indeed, having a drone follow your friend’s home or perform aerobatics sounds impressive to me.
What Do You Need To Know About Programming Drones?
Are all drones programmable? Definitely no. Consumer drones come ready for use, with no allowance to reprogram or add programmable components.
But there are programmable drones mainly designed for use by learners and hobbyists. If you find them less exciting, there are DIY drone kits to assemble a drone from scratch. With these kits, you get to customize a drone to your taste.
How hard is it to assemble one? For sure, as many advanced robots, drones are hard to build from scratch. Several levels of programming (more on this in a few) need to be done.
Hey! Don’t throw away that drone programming project yet. Because the robot operating system (ROS) got you covered. Once you assemble your drone, install ROS.
You then only need any of the many compatible programming languages to custom program the drone.
Which programming language do we need to code for drones?
A drone has two layers of programming, hardware, and software programming.
This is low-level programming to build the basic functionalities of your drone. It involves making the firmware that links the processor with the sensors and actuators.
The drone’s firmware defines how the motors, battery, propellers, and other hardware aspects relate.
For example, most drone applications require steady and level flights. To achieve the required flight, the processor sends varying amounts of power to different motors.
The firmware determines the exact power needed based on information from the drone’s inertia measurement unit.
For programmable drones, the most preferred firmware programming languages are C, C++, and Assembly. While the learning curve for these languages is steep, the fun starts once you get the basics.
What’s more, you can practice firmware programming using simulators before getting on a real drone.
The DIY/modular drones are different. The hardware kit determines the language you need to code the firmware.
The most popular modular drone kits being Arduino and Raspberry Pi. For instance, an Arduino modular requires Arduino, which is not a language but a set of C/C++ codes called through Arduino sketch.
Modern drones have made firmware programming easier. The firmware code exists within the ROS for easier drone control.
To add more code to the ROS, you only need to create specific node programs in a programming language compatible with ROS.
A drone is a complete unit that accepts commands to perform different tasks. For example, your drone needs instructions to control speed, flight altitude, or flight paths. Firmware interprets these commands and serves the intended function.
Software programming deals with creating commands for different drone applications. It mainly involves the use of high-level programming languages such as Python and Java. The language to use depends on the drone’s application programming interface (API).
For instance, if the drone has a Java-based API, you use Java to code through an interface. There are other APIs based on other languages, such as C/C++. However, drones running on ROS can accept commands from multiple programming languages.
Basically, you need to learn C, C++, and Python or Java to fully program your drone from scratch to flying.
What Do You Need For a Drone Project?
A drone project requires the following:
- A programmable drone or
- A DIY/modular drone kit
- An SDK/API
A Programmable Drone:
As indicated above, drone programming offers a fun way to learn and improve on your coding. An ideal programmable drone should have many programmable features for your experimenting. With the drone industry expanding fast, there are numerous choices at your disposal.
The most basic programmable drones let you change the essential functions like the flight patterns. Such drones lack advanced features like GPS and cameras.
For better room to exercise your coding, opt for programmable drones with gyros, barometers, and other sensor modules inbuilt.
A drone with advanced features may be challenging to program. Still, the added features offer several ways to solve a problem.
Most of these drones allow for third-party programming tools and languages. Further, there are several open-source and proprietary drone development tools available to make your coding more accessible.
Here are the three best programmable drones:
