Boosting your drone development

Custom flight controllers

About Us

Since 2016, we modify the PX4 flight stack for custom needs, we used it on several vehicles including quadrotors, hexarotors, tailsitters, tilt-rotors, tilt-wings, turbojet powered personal vehicle and more!

PX4 is free to use and modify under the terms of the permissive BSD license; even for proprietary and commercial applications. It is the choice of many companies, why not you?

PX4 is not owned by us. It is the result of many collaborators across the globe and is open source.

Consulting Services

Flight Controller Customization

We create custom flight controllers for your application. Whether you need a custom driver, a custom command, a custom mode, or a complete redesign of the flight controller, we can do that for you.

Simulation and Hardware-In-The-Loop

Every modification is tested in a HITL simulation before delivering to the client to ensure the desired behavior.


We can also implement a model for your custom vehicle in the HITL environment.

PX4 Workshops

These series of workshops are meant to help our client understand the PX4 code base in order to creating their custom control algorithm, commands and applications.

Check an open source project by us: the Simulator-In-Hardware, a low cost and real time HITL simulator.

 

Approach

Example project: custom controller for a non-conventional vehicle

Geometeric Graph

1. System analysis and modelling

Your custom vehicle needs a mathematical model. We will develop it for you with a component based approach. We may require specifications and a set of bench test data from your actuators.

At this stage the controller is designed based on the needs of your vehicle and your application.

2. Implementation in a Hardware-In-The-Loop simulator

This model is then implemented in the HITL simulator. The more accurate the bench test data, the closer to the reality the simulator will behave.

Coding

3. Controller development

The controller is developed according to your needs. It is then tested in the HITL environment to ensure the desired behavior.


PX4 is a very versatile flight stack design for reusability. It is therefore possible to control a non-conventional vehicle with minimal modifications.

4. Flight tests

Once the code is delivered, we will assist you step by step for the flight tests, ensuring a safe operation and a correct set of control gains.

If you have a team to integrate the system and pilot it, we can assist you remotely along the entire path.

About ethics

Are you making this world a better place?

Let us know if your project is in the humanitarian sector. We would love to assist you on it!

Are you open to share your project?

We believe in the power of open source ecosystems. If you choose to share your project with the open source community, Altitude R&D will give you a discount on the source code development.

No weapon policy

For ethical reasons we choose not to work with weaponized systems. We thank you for your understanding.
