At Fusion Engineering we are working to create the most reliable, flexible and easy-to-use flight controller for any type of multirotor drone. We have started from the ground up, developing our own flexible and reliable software platform. On top of this platform, we built innovative flight control algorithms to ensure more accurate positioning, disturbance rejection, and fault tolerance.

We work closely together with the Delft University of Technology on the latest research in drone control technology, to make sure our flight controller always contains the cutting edge of technology. The control technologies that we have implemented are based on a High-rate UKF, Adaptive INDI, and Fault-tolerant control.


The DroneBox is a powerful flight controller platform with everything you need to get your drone flying reliably. It comes with our flexible and reliable software platform and our advanced software modules for state-estimation, flight control, and fault tolerance.

Optionally, your own software can be easily integrated as well, allowing you to run your own custom controllers, drive additional custom hardware, or even run a whole other platform such as PX4 inside our framework.

It runs Linux on a powerful 64-bit quadcore ARM-based processor and has plenty of RAM and flash storage. It has connectors for all commonly used digital interfaces such as CAN, I2C, SPI, UART, and more.

Who We Are

Fusion Engineering was founded in 2017 in Delft and has grown considerably ever since. Together, our team has backgrounds in software, electronics, control, aerospace, mechanical engineering, finance, management, and more. Our speciality is combining the best of different fields into a consistent and optimal solution. Hence our name, Fusion Engineering.

One of the keys to successfully innovating while combining the latest and greatest from different fields lies in our culture of learning and teaching. Each and every one of us is always eager to learn, teach, and evolve—both inside and outside their field of expertise—which makes our teamwork so effective.

Our Mission

Our mission is to make drone flight so safe and reliable that it can be seamlessly integrated into our daily lives. While drone hardware has come a long way over the past decades, we realized that software development has been lacking behind. We therefore set out on an ambitious project: Developing drone control systems from scratch, while focussing from the start on safety and reliability.
