Today a general need for robots assisting different human activities rises. The goal of the present project is to develop a general purpose data collector framework, which provides facilities for attaching and fitting different kinds of sensors and actuators. This general purpose framework provides an easy way to turn a general purpose robot into a special function one. The final concrete goal of the present development is to develop an autonomous robot assisting clinical patients and/or elderly persons. The work is going on towards the next phase, when the collector framework will be attached to a medical robot. The presented framework will handle the sensors and the motion of the medical robot it will be attach to an iRobot or a same instrument. Furthermore, users and developers can apply the framework several other implementations.

This paper introduces the Fractional Variable Order Discrete System, described in the state space. The paper also introduces results on the controllability, reachability, observability and stability of that system. The definitions of the notions of controllability, reachability and observability for such models are proposed and the necessary and sufficient conditions for reachability and observability are given and proven. The sufficient conditions for controllability and local stability are proposed too.

At the Technical university of Košice was developed and designed equipment for static tests of pipe conveyer belts. The article deals with using of new Computer Integrated System for the automatized measuring of strength in the conveyer belt of pipe conveyor. Measuring system, measuring process and form of record results and their interpretation are presented in this paper. Values from 24 pieces of strain gauges are recorded simultaneously. The valuation of measurements was performed by statistical characteristics, Shapiro-Wilk normality test, test for the Weibull distribution and test of casualness. We also created mathematical description from measured variations of compressive forces by using non-linear dependence.

The most common image feature extraction algorithms such as SIFT (Scale Invariant Feature Transform) and SURF (Speeded Up Robust Feature) have been proven to be invariant to changes in rotation, scale and with restrictions to illumination and viewpoint changes. These algorithms generate descriptor vectors around keypoints in 2D images. Close descriptors suggest similar image patch. In case of mobile robotics applications it is important to achieve good viewpoint invariance and stability to detect landmarks and objects with high reliability. Improving viewpoint invariance for image feature detection increases the efficiency of SLAM algorithms. In this paper we present and evaluate a method to use additional data provided by range image sensors to supplement traditional feature extraction algorithms to improve viewpoint invariance. We present the method and results of computer simulation and also real world examples comparing the SURF (OpenSURF) with and without the improvement. An active structured light based range and intensity image sensor was used to acquire real world test images.

The paper deals with kineto-static analysis of the AGgressive Environment roBOT (AGEBOT). Serio-parallel kinematic architecture of AGEBOT plays important role in aggressive environment applications such as manipulation in industrial degreasing and paint removing lines in the presence of high pressure and temperature, acid or lye. Standard 4DoF serial manipulator with PRRR joints is equipped with special 3DoF parallel spherical wrist which makes possible to separate vulnerable components (motors, sensors) from the rest of the end-effector by a water-proof barrier. Inverse and direct kinematics are discussed. The algorithm for velocity, acceleration and static forces (gravity compensation) is derived. In the case of known inverse and direct position dependencies proposed algorithm can be generalized for an arbitrary serial or parallel manipulator.

Nowadays the power supply of electronic circuits which are beyond a reach of main power supply is relatively complicated problem. In our case, if we consider that wireless sensor network of IEEE 802.15.4 standard is not limited to the interior we rely on an alternative power source for the power supply of intelligent wireless modules. Leaving aside the purely alternative power source supplying energy directly into electricity distribution network, we are thrown upon a combination of battery - alternative source. The paper contains a solution of a functional system applying a solar panels and Li-ION batteries for power supply of intelligent wireless modules of sensor network.

This article is focused on description of four ways of tracking control on the modeling yard. The yard is situated in the laboratory of Department of control systems and instrumentation. Control system was continuously developed by the help of students. First step was connecting the particular model's objects to input/output devices of the PLC control system and creating the basic programs. Next steps were design and creating of the hand control panel, creating of display views in InTouch software, design and creating of digital control panel and digitalization of locomotives. For every new created hardware and software control components, the program modules were developed (for PLC). The model yard is fully operable at present.

Process control is one of the principal approaches to increase process quality and performance. Model based control system is based on real time mathematical model, which can be used at individual levels of the process hierarchy in the on line real time control system. The model is used for interpretation, planning, and execution of the tasks through the autonomous controllers. For the outlining tasks, a human operator controls a simulation model to generate a sequential list of desired sub-goals. The human operator is specifying controller's set-points and allowing the autonomous control capabilities of the furnace to coordinate the actual trajectory between set-points. Provision is made to preview the proposed trajectory for approval or modification before execution. Developed model is used for the support of direct and supervisory control. On the basic control level the model is used for process monitoring and process prediction. Supervisory level model is used for process planning, and execution of the task segments through the autonomous controllers. The autonomous control capabilities of the furnace are used to coordinate the actual trajectory between set-points. The rotary furnace predictive control, model was used on the direct and supervisory control level. Basic control level include process monitoring and process prediction.

An ongoing development at University of Debrecen, Faculty of Informatics is to convert a commercially available remote controlled all-terrain robot into an autonomous one. In the present phase our goal is to prepare the vehicle for autonomous tasks. To move autonomously, the robot needs to know some information about its surroundings. Therefore, some sensors are necessary to be developed. Till now, GPS receiver, accelerometer, magnetic field sensor and eight ultrasonic based distance sensors have been developed and connected. As we want the robot to solve tasks, we need to place a processing unit on board. There are two options we are working with. One is Altera's Development and Education board 2, the other is National Instruments' Single Board RIO 9632. Software development is in progress for these platforms simultaneously. Various collections of sensors and high performance real-time control unit make the robot capable of being great test device of complex autonomous algorithms, such as route following and path finding algorithms. A state-of-art report is presented.
