This article presents a modular, distributed and scalable many-camera system designed towards tracking multiple people simultaneously in a natural human-robot interaction scenario set in an apartment mock-up. The described system employs 40 high-resolution cameras networked to 15 computers, redundantly covering an area of approximately 100 square meters. The unique scale and set-up of the system require novel approaches for vision-based tracking, especially with respect to the transfer of targets between the different tracking processes while preserving the target identities. We propose an integrated approach to cope with these challenges, and focus on the system architecture, the target information management, the calibration of the cameras and the applied tracking methodologies themselves.

In this paper, a new adaptive fuzzy controller is proposed for trajectory tracking of wheeled mobile robots by visual servoing. The control algorithm is developed so that it can take care of parametric uncertainty associated with the vision system and the mobile robot dynamics. The system uncertainty associated with nonlinear robot dynamics is estimated by an adaptive fuzzy logic system (FLS) and the uncertain camera parameters are updated online. The controller is designed based on Lyapunov stability theory. Simulation results are presented to illustrate the performance of the proposed controller.

The paper deals with technologies for the intelligent manipulators capable of making creative decisions automatically while operating. As examples of tasks classic puzzle problem and the table games like "Gomoku" or "Go" are considered. PlannerM (universal planning program) was developed and applied to solve the first task. The program was implemented on anthropomorphic kinematics model of a dynamic manipulator and on Visual Prolog and was realized on NAO robot (android robot). The second task was investigated from the point of view of the manipulator testing on the ManGo robot, its dynamic model, vision system and control system were tested. The logical moves choice program in the game "Gomoku" is designed in Prolog and C languages. Besides classical algorithms utilization, considerable attention has been given to the application of neural network paradigms for manipulators control. The elaborated robots passed experimental working off which allowed to draw conclusions about the software and hardware effectiveness in the implementation of various manipulators control algorithms.

To realize the vision of ubiquitous computing, it is important to develop a context-aware system which can help ubiquitous agents, services, and devices become aware of their contexts. Context-aware system is required to be capable of configuring appropriate context model and managing it through the context manipulation. In this paper, we propose the context space and the conceptual structure for context acquisition, representation, and utilization. We also describe how this conceptual structure is implemented in the service robot area. As the result of the research, we developed the CAMUS (Context-Aware Middleware for URC Systems) which is a context-aware server framework for a network-based intelligent robot system and applied it to the field test.

vision navigation and location is a main function in the vision system of intelligent agricultural mobile robot, and the edge feature of images is an important feature for vision navigation and location. According to the characteristic of cropland scenery, a compactly supported dyadic antisymmetric wavelet with respect to origin is brought forward to detect edges of cropland image. A set of filters were given that can be used to construct the edge detecting wavelet. The edge features are provided by determining the local maxim of wavelet coefficient at dyadic scale of the image. After the computer simulation was carried out on the cropland image, the continuous and smooth edge image can be got. The edges of cropland scenery are extracted accurately. The experiment result reveals that the method is efficient and practicable.
