Programming Autonomous Flight
Learning real-world coding skills through programming drones combines practical experience in both software development and robotics. Using tools like DroneBlocks, Python, and the PX4 flight stack, alongside advanced sensor technologies like optical flow, provides a comprehensive, hands-on approach to drone programming.
Optical Flow Sensing
Developed in collaboration with ARK Electronics, DEXI introduces a groundbreaking all-in-one flight controller running PX4 Autopilot that integrates optical flow sensing for incredibly accurate positioning while flying in GPS denied environments. Optical flow sensors measure the motion of surfaces below the drone by detecting the movement of patterns in imagery captured in real-time.
Python Programming
Python, being a versatile programming language, is perfect for interacting with PX4 due to its readability and wide support for libraries. Learn about MAVSDK-Python, A library that provides a high-level API to control PX4 using Python. This can be used to write scripts that control the drone, fetch telemetry data, and more. Python scripts can automate complex tasks like flight missions, data logging, or real-time decision making based on sensor data.
ROS
The integration of ROS with PX4 provides a powerful platform for developing sophisticated autonomous drone applications. PX4 is a popular open-source flight control software for drones and other unmanned aerial vehicles. When combined with ROS, it enables advanced robotics tasks that involve more than just basic flight control, such as autonomous navigation, obstacle avoidance, and interaction with the environment.
Computer Vision with Open-CV
Using OpenCV (Open Source Computer Vision Library) with a drone's Pi Camera on an onboard compute platform allows the drone to process visual data in real time, enabling it to perform tasks like object detection, tracking, and navigation based on visual cues. OpenCV can be used to detect objects in the video stream from the Pi Camera using various techniques like color space conversion, edge detection, or more advanced deep learning models.
Hardware

Perfect for educators looking to integrate real-world applications into their curriculum, DEXI lays the foundation for students to explore and innovate in STEM fields.
Access to GPIO
Access to the GPIO pins on DEXI can be incredibly useful for a variety of tasks that enhance the drone's capabilities and functionality. GPIO pins can output control signals to various components of the drone. For example, Control LED lights for visual feedback or illumination during night flights or manage additional servo motors for moving parts, like a camera gimbal for angle adjustments or releasing a payload.
Payload Capacity
With a payload capacity of up to 0.5 lbs DEXI offers a range of benefits and opens up various possibilities for both recreational and professional applications. Engage in hands-on learning by attaching various scientific sensors or experimenting with different types of payloads to understand physics and engineering principles. Payloads can include but are not limited to cameras, sensors, servos, communication devices, and research instruments,
Compliance
The DroneBlocks DEXI drone meets NDAA compliance as outlined by Section 848 of the Fiscal Year 2020 National Defense Authorization Act (NDAA). This compliance is achieved because its critical electronic components—including flight controllers, radios, data transmission devices, cameras, gimbals, ground control systems, operating software, and data storage—are all manufactured in the United States.
