An inertial measurement unit (IMU) is an electronic device that measures velocity, orientation, and gravitational forces using a combination of accelerometers, gyroscopes, and magnetometers. IMUs have a lot of applications in robotics; some of the applications are applied in balancing of unmanned aerial vehicles (UAVs) and robot navigation.

In this section, we will discuss the role of IMUs in mobile robot navigation and some of the latest IMUs on the market and their interfacing with Launchpad.
