The aim of this thesis is the construction and production of an IMU module which is easily attachable to any vehicle equipped with autonomous direction system. One of the major requirements of this module is compact size that makes its implementation in any vehicle easy as no reconstruction is necessary. Another determinative attribute of the module is fast data processing. This feature plays an important role in maintaining the stable motion of the vehicle. The module should be able to process data with appropriate speed enabling the smooth correction of the vehicle’s position. Due to this feature the module is suitable for unstable vehicles such as a quadrocopter.
The module includes three sensors (gyroscope, magnetometer and accelerometer), a microcontroller and a communication interface. The microcontroller’s main task is processing data from the sensors and forwarding it through the communication interface to the control system of the vehicle. In sum, the function of the module lies in defining the accurate relative position of the vehicle with appropriate speed, to achieve stable motion and extended reliability.
