Development and Evaluation of a Low-Cost Dynamic Motion Platform for Investigating Inertial Measurement Unit Behavior Using the MPU6050 Sensor

Abstract

This study is based on the investigation of the dynamic movements and behavior of the MPU6050 IMU sensor under different motion circumstances, with the help of a specially designed test apparatus. The MPU6050 has three axes of gyroscopes and accelerators, which make it significant in most systems related to motion. Yet, because the outcomes of classic techniques are unrefined, they may include noisy data, stray statistics and errors in measurement. The motion platform was designed to use an Arduino, various servo motors, ultrasonic sensors and a system to record effects of impacts. The device can reproduce both straight and curved movements, set to different tilt levels (for instance, 60°), allowing real-time measurement of acceleration and angular displacement. Results from the sensors showed that large discrepancies were found in roll measurements when the aircraft moved and turned, compared to changes in pitch and yaw. In this study, the value of gravity and dynamic motion is highlighted, and it introduces a practical strategy for setting up and correcting the output values from IMU sensors. Results from experiments make it simpler to create and improve motion-sensitive systems in robotics, navigation and stabilization.
