The design, construction and control of a four-degree-of-freedom hybrid parallel/serial motion platform for the calibration of multi-axis inertial measurement units
The Department of Mechanical Engineering and the Avionics Engineering Center at Ohio University are developing an electromechanical system for the calibration of an inertial measurement unit (IMU) using global positioning system (GPS) antennas. The GPS antennas and IMU are mounted to a common platform to be oriented in the angular roll, pitch, and yaw motions. Vertical motion is also included to test the systems in a vibrational manner. A four-DOF system based n the parallel Carpal Wrist has been developed as a test platform for this calibration process. High-accuracy positioning is not required from the platform since the GPS technology provides absolute positioning data for the IMU calibration.
