This ESP32 Drone Flies Autonomously… Without GPS! | Optical Flow + ToF Positioning Module Demo

In this video, we demonstrate indoor drone position hold using an optical flow sensor and Time-of-Flight (ToF) height sensing without the use of GPS. Wiki Page: https://circuitdigest.com/wiki/litewi... More information: https://circuitdigest.com/microcontro... Buy LiteWing Drone + Position Module: https://quartzcomponents.com/products... The LiteWing Drone Positioning Module combines the PMW3901 optical flow sensor with the VL53L1X ToF height sensor to enable stable hover, drift correction, and joystick-based fly-and-hold control. When the joystick input is released, the drone automatically maintains its position using dead reckoning and PID control. 🔹 No GPS required 🔹 Indoor drone positioning 🔹 Optical flow based position tracking 🔹 Real-time PID stabilization 🔹 Full working demo with trajectory visualization This setup is ideal for robotics students, DIY drone builders, and engineers experimenting with autonomous flight in GPS-denied environments. ------------------------------------------------------------------------------------------------------------------------ Please Like, Share, and Subscribe to our YouTube Channel: https://www.youtube.com/Circuitdigest...
