Overview
This course teaches how to use an MPU9250 Accelerometer, Gyroscope, and digital Magnetometer to position robots. The learning outcomes include understanding how the MPU9250 works, calibrating and dampening readings, and converting raw readings into degrees and radians. The course covers topics such as orientation, MEMS sensors, data processing, calibration, and filtering. The teaching method includes a video tutorial with practical demonstrations. The intended audience for this course is individuals interested in robotics, Raspberry Pi Pico, MPU9250, and MicroPython.
