Background
An IMU (Inertial measurement unit) is a device that measures the three-axis attitude angle (or angular velocity) and acceleration of an object. And the attitude displacement can be precisely adjusted by calculating the attitude data measured by the IMU.
The IMU is mainly applied to equipment needing motion control, such as automobiles and robots, and is also applied to occasions needing precise displacement calculation by using postures, such as inertial navigation equipment of submarines, airplanes, missiles and spacecrafts.
The IMU is susceptible to deviation of measured data due to external vibration, and therefore, the IMU needs to be subjected to a shock absorption operation.
