Accelerometers and Gyroscopes - Sensor Fusion #1 - Phil's Lab #33

Part 1 of sensor fusion video series showing the need for combining sensor data, for example, to estimate the attitude of an aircraft (e.g. UAV) using an inertial measurement unit (IMU). Benefits and problems of typical sensors, such as accelerometers and gyroscopes. Real-world, practical considerations and demonstrations on a real-time embedded system (STM32-based, using the C language). Future videos will cover complementary filters and extended Kalman filters.
