Some of the most interesting applications for MEMS IMUs involve a purposeful blend of multiple inertial observers, in addition to the IMU. While this article was published a few years ago, it serves as a relevant reminder of how combining independent sensing technologies can create exciting, life-changing functions. In this case, GPS, Laser, wheel-based odometers and the MEMS IMU combine to provide very accurate, autonomous robot operation.
For more information on this application, please read, Inertial Sensors Facilitate Autonomous Operation in Mobile Robots, which was originally published in the August 2010 issue of Analog Dialogue. We hope that you find this useful and look forward to your feedback.
