Nowadays, mobile robots are commonly used for industrial and household appliances. A popular group of mobile robots uses differential drive, because of its simplicity and low cost feasibility.

This paper is about the developing process of a robot with this type of drive. The thesis includes the design of the hardware, the implementation of the control software, which includes the thorough analysis of the speed control. By testing the finished model the evaluation of the robot also took place.

One of the goals was to create a robot model, which maintains the possibility of future development and research.

The finished robot can be controlled via Bluetooth communication and has the ability to move with a determined speed and angular speed due to the implemented controllers. The design of the hardware gives potential to use an ultrasonic range sensor to detect objects in front of the robot and gives the possibility to create a system which uses infrared LED-s to get the absolute position of the robot.
