  A model vehicle has been developed further in order to perform automatic parking. Ultrasonic sensors and STM32 F4 Discovery microcontroller have been mounted. The driving assistant system can find the parking place then parallel parking is performed. The backward motion of the vehicle is carried out along two circular paths, which is followed by corrections of the position and orientation.

  The topic of the research is the design and building of a UGV (Unmanned Ground Vehicle), which we can control wirelessly with a glove designed for this purpose. The design and use of this gesture-controlled robot can be observed in this summary. A camera will be installed on the robot unit, whose image we can query through the local network. Furthermore, the hardware and software for this camera system will be described as well.

  This paper presents the way how the hard iron effect could be compensated and a way to implement it on a small power device such as a microcontroller. Because of the magnetized materials that can stay near a magnetometer sensor and because of the very small magnetic field of the Earth, before the use of the measured values from a magnetometer to determine the heading (angle with the N direction) of the sensor a compensation is needed.

  This paper presents the development process starting from a simple electronic module for amplification of EMG signals. During development the tasks to be solved were extended towards the creation of an EMG-base controller that eventually can be connected to a PC. Among the main goals were the simplicity and low cost of production. There are similar devices commercially available, but the main focus was on the whole process of design, testing, fabrication and the exploration of application areas. It was important to use medical recommendations. The device matches the suggestion of SENIAM, except for the resolution of A/D conversion, which is permissible due to the fact that it was not designed for medical purposes. The final version is capable of detecting and amplifying EMG signals, with the appropriate filtering and digitizing procedures for further processing. With the development of wireless communication capabilities, the device which can be attached to the forearm can be used as a USB HID device with a PC. A number of additional applications are also discussed, pointing out the fact that this piece of technology offers a wide range of possibilities.

  Hardware in the loop testing is increasingly important product testing for cutting down time to market. In my previous article I identified the parameters of a DC motor control system using system identification. An implementation of the resulting transfer function was developed on an ARM based hardware in the loop system and has been verified against the original system. The results show that the hardware in the loop system produces responses within tolerance to the stimulus signals and can be used for testing of controlsystems.
