Manipulator Mechanism for the Mobile Robotic System

Jiří FISCHER and Jan KOŘÍNEK

Abstract


The aim of this article is to describe the creation of manipulation device with three degrees of freedom as a superstructure for wheeled robotic undercarriage. The main task is to analyse the actuators used for each of rotary units, calculate the kinematics of the entire mechanism, choose the configuration and construction of the manipulator. The result is a 3D computer model and the manipulation device realization.

Possibilities and Uses of Robotic Chassis

Václav BÁŠA and Jaromír HOŠEK

Abstract


The article deals with analysis of robotic chassis. We analyzed possibilities of that chassis, its capabilities during movement through known terrain and its accuracy. The control system of this chassis is based on Arduino unit. We checked possibilities of programming this unit and functionality of their commands. Purpose of these experiments is to find possibilities of this chassis while moving in rough terrain.

Keywords


Robotic chassis, Arduino unit, Moving in terrain.

Methods of Image Processing and Computer Vision

Vadim STARÝ and Tomáš MATYSKA

Abstract


The article contains the overview of the most widely used methods for image processing, brief description and adumbration of possible utilization. In the introduction there are described general assumptions, advantages and disadvantages of each method. Methods are verified on suitable demonstrational tasks. Based on this tasks and results general logical models were created. Tested and described image processing methods are: shape (edge) detection, blobs detection, template matching, feature matching, using linear classifiers and artificial neural networks.

Keywords


Image recognition, Image processing, Image analysis, Artificial intelligence, Neural networks.
