Odometer module for mobile robot
 Davídek, Daniel ; Burian, František (referee) ; Jílek, Tomáš (advisor)
The main objective of this work was the development and realization of odometric module for mobile robot envMap. The module processes signals from the incremental encoder and then calculates the position and direction of the robot together with the probability of its occurrence. The calculated data with a time stamp obtained from the GPS, are then sent to the above-system via the serial interface. For the realization the development board STM32F407G was chosen. f this board can be configured to function as an encoder input. This minimizes the possibility of encoder data loss when external interrupts are handled. The STM32F4 will not be any pull-back in the later development as there are plenty of peripherals on STM32F4. They were designed with two printed circuit boards: the reduction for the GPS module and shield-board for STM32F4. The equations for calculating odometric information and the probability of occurrence are included in this work. To calculate the movement of the robot, the equation considering only the movement on the plane surface is chosen. Later in this thesis there is also description of the source code for the STM32 and its functionality. In the results there is a complete connecting diagram along with the description of the utility program ODOMAT and communication messages. Finally, measurements correcting systematic error in parameters of the robot are described and there is the final odometry measurements compared with GPS localization as ground truth.
