Behavior-based control system of a mobile robot for the visual inspection of ventilation ducts

The paper deals with the implementation of a behavior-based control and learning controller for autonomous inspection robots. The presented control architecture is designed to be used in the mobile robot (Amigo) for the visual inspection of ventilation systems. The main aim of the authors’ study is to propose a behavior-based controller with neural network-based coordination methods. Preliminary results are promising for further development of the proposed solution. The method has several advantages when compared with other competitive and/or co-operative approaches due to its robustness and modularity.

Applications of augmented reality in machinery design, maintenance and diagnostics

The paper deals with technical applications of Augmented Reality (AR) technology. The discussion starts with the conception of AR. Further on, three applications connected with different stages of existence of a technical means (machinery or equipment) are presented. They address design process, maintenance and diagnostics of different objects. Finally, further research is outlined.

Control system of the inspection robots group applying auctions and multi-criteria analysis for task allocation

In the paper presented is a control system of a mobile robots group intended for carrying out inspection missions. The main research problem was to define such a control system in order to facilitate a cooperation of the robots resulting in realization of the committed inspection tasks. Many of the well-known control systems use auctions for tasks allocation, where a subject of an auction is a task to be allocated. It seems that in the case of missions characterized by much larger number of tasks than number of robots it will be better if robots (instead of tasks) are subjects of auctions. The second identified problem concerns the one-sided robot-to-task fitness evaluation. Simultaneous assessment of the robot-to-task fitness and task attractiveness for robot should affect positively for the overall effectiveness of the multi-robot system performance. The elaborated system allows to assign tasks to robots using various methods for evaluation of fitness between robots and tasks, and using some tasks allocation methods. There is proposed the method for multi-criteria analysis, which is composed of two assessments, i.e. robot’s concurrency position for task among other robots and task’s attractiveness for robot among other tasks. Furthermore, there are proposed methods for tasks allocation applying the mentioned multi-criteria analysis method. The verification of both the elaborated system and the proposed tasks’ allocation methods was carried out with the help of simulated experiments. The object under test was a group of inspection mobile robots being a virtual counterpart of the real mobile-robot group.

Teleoperated multi-robot group for technical inspections

In this paper, the authors discuss results of the research concerning a group of multitasking mobile robots that use advanced technologies. The main goal of the paper is to illustrate functionality of the robot group, wireless communication and control system based on Wi-Fi standard as well as architectures of the selected subsystems. The developed robots allow aiding humans in accomplishing tasks in an environment that may be dangerous. The group consists of teleoperated robots: a transporting robot, an exploring robot, and small monitoring robots. Teleoperated robots can be used most often as moving sensor devices. The group of robots is capable of monitoring and carrying out measurements of selected physical quantities, which can occur within the territory of any object, and then transmitting the data to the user. Additionally, elaborated exploring robot can survey an area of terrain with visual inspection and take samples of soil.
