    We present a fast and precise vision-based software intended for multiple robot localization. The core component of the proposed localization system is an efficient method for black and white circular pattern detection. The method is robust to variable lighting conditions, achieves sub-pixel precision, and its computational complexity is independent of the processed image size. With off-the-shelf computational equipment and low-cost camera, its core algorithm is able to process hundreds of images per second while tracking hundreds of objects with millimeter precision. We propose a mathematical model of the method that allows to calculate its precision, area of coverage, and processing speed from the camera’s intrinsic parameters and hardware’s processing capacity. The correctness of the presented model and performance of the algorithm in real-world conditions are verified in several experiments. Apart from the method description, we also publish its source code; so, it can be used as an enabling technology for various mobile robotics problems

    A Tool for Mobile Robotics Research

    This paper introduces TeamBots as a tool for mobile robotics research. TeamBots enables researchers to develop robotic control systems and test the control systems in simulation as well as on physical robots. Simulation plays important roles in multi-robot research. Interaction among robots in multi-robot systems can produce interesting phenomena. It is hard to predict the effectiveness of a control system without simulating it in a multi-robot environment. This paper presents a case study and compares it to closely related work. The experiment result shows that even for the same task (i.e. foraging) a control system that performs best in a particular environment may not be the best control system in different environments

    This paper describes the integration of robotics education into an undergraduate Computer Science curriculum. The proposed approach delivers mobile robotics as well as covering the closely related field of Computer Vision, and is directly linked to the research conducted at the authors’ institution. The paper describes the most relevant details of the module content and assessment strategy, paying particular attention to the practical sessions using Rovio mobile robots. The specific choices are discussed that were made with regard to the mobile platform, software libraries and lab environment. The paper also presents a detailed qualitative and quantitative analysis of student results, including the correlation between student engagement and performance, and discusses the outcomes of this experience
