Reflex Introductory Model FAQ

The Fusion Reflex IM is the foundation of our envisioned system, the core of the platform. This version contains simple yet effective flight control algorithms captured in a fail-safe software architecture, running on specifically designed hardware, optimized to ensure maximum performance.

The Reflex IM is perfect for those who enjoy being early adopters of ground-breaking tech. The IM really is the bare bones of the Reflex model that is in development. But of course, you don’t have to keep it laying around on the shelf: it is fully capable of flying your multirotor drones. This first model is designed for you to get accustomed to our platform through testing it.

The Reflex IM is meant for prototyping and testing, not yet for live missions/operations.

The Fusion Reflex IM is perfect for drone manufacturers that work on drone applications for the future. With the Reflex IM, you’re one of the first to get your hands on a flight controller that will completely change the commercial drone landscape.

As an early adopter, you will be the first to receive updates along our development roadmap, including:
● Trajectory control
● Triple GPS for heading support
● The implementation of our INDI algorithms
● Fault-tolerant flight control

Software and specifications FAQ

Our flight controller uses a technique based on Incremental Nonlinear Dynamic Inversion (INDI): a novel method designed at TU Delft that overcomes the robustness issues of NDI by reducing the dependency on an accurate system model while still allowing for a precise and fast response.

Its combination of fast sensor update rates and a nonlinear control law allows for precise and aggressive manoeuvres. The use of acceleration measurements allows the control law to capture unmodeled dynamics, such as gust wind disturbances, and effectively cancel these without any modelling assumptions.

In order to increase the reliability and certifiability of drones even more, we are designing fault-tolerant control systems to equip multicopters with an additional layer of safety. Relying on fast detection of rotor failures, our fault-control system is able to steer a damaged multicopter to safety, even after complete loss of one of the rotors. Despite the loss in controllability of the drone, the combination of INDI with a novel in-house developed control technique allows the damaged drone to still land safely.

Software on our platform is split up in separate modules which run as independent isolated processes, such that a bug in one cannot take down other tasks. Even if important modules would crash mid-air, the drone will keep on flying just fine, as modules can be immediately restarted without interrupting communication with others. This way, an unexpected failure will not take down the whole system. This flexible set-up also allows you to easily add your own software modules to the system, without risks.
