Opis:
Transport has always been a fundamental impulse for the development of civilization. The first fully automatically controlled vehicles for industrial application (previously called driverless vehicles) was design in 1954 year. This has been achieved more than 60 years ago. Unmanned Ground Vehicles are a whole family of autonomous vehicles use modern tools with all power today available electronics for navigation task and decision making process on the base artificial intelligence and (AI) algorithms. At present time a problem of the realization a fully reconfiguration navigation system working in real time mode for UGV vehicles is the subject of the research for many scientific units of the entire scientific world. The object of the statement constitute AGV short historical outline with actual trends marking. The special authors' attention was focused on the solutions dedicated for so-called e-tools functionalities implementing in modern AGV vehicles. The main purpose of the article was focused on the set of issues involving the most problems in the whole material handling (MHD) family devices with any autonomous factor. The article is focused on the localization problem, trajectories founding, path planning, scheduling, workspace with environment mapping and AGV control issues. Described methods and tools are connected with chosen artificial intelligence solutions dedicated or adapted for autonomous vehicles' needs.

Opis:
The paper talk over the proposal of use a combined vision system architecture for solved well known issue occurring in material handling devices (MHDs) exploitation, especially in the crane devices. The described in the presented paper stereovision system for work space mapping and non-contact sensor type for rope angle swinging measure were a part of solutions enabling a full autonomous navigation system (ANS) realized by the overhead travelling crane. In the paper special authors care was dedicated on two issues. The first one was connected with MHDs workspace mapping with built three-dimensional model of their structure. The second part of the paper considering the possibility of attaches image analysis technique into non-contact rope swinging sensor architecture. In this paper, two main problems were identified: crane workspace visualization and need of develop new type of anti-sway technique. For workspace, visualization technique of author's proposed, well known stereovision, but not in standard architecture (to compose stereovision picture one camera was use). In terms of anti-sway technique, authors choose close-loop control system. Thus was develop non-contact anti sway sensor. The common point of both developed methods (anti sway solution and workspace visualization) is vision methods. At the end raises a following conclusion: vision systems and image analysis method are perfect not only in acquiring an information about crane workspace and potential obstacles dimension (stereovision), but also useful as a standalone measurements system of chosen and useful crane parameters. All tests were conducted on the physical model of the scaled overhead travelling crane with 150 kg hosting capability.
