Using a low-cost IMU – 9 degrees of freedom


"An inertial measurement unit, or IMU, is an electronic device that measures and reports on a craft's velocity, orientation, and gravitational forces, using a combination of accelerometers and gyroscopes, sometimes also magnetometers. IMUs are typically used to manoeuvre aircraft, including unmanned aerial vehicles (UAVs), among many others, and spacecraft, including satellites and landers."


In this section, we will learn to use a low-cost sensor with 9 Degree of Freedom (DoF). This sensor has an accelerometer (x3), a magnetometer (x3), a barometer (x1), and a gyroscope (x3). 9DoF Razor IMU and the 9DoF sensor stick are low-cost IMU that can be used in your robotics projects. The two boards ...
