Wheeled robot soccer is a soccer robotthat moves with wheels with several capabilities, such as detecting, catching, dribbling, and kicking a ball. A robot soccer requires a system or sensor to detect a ball. the development of computervision technology enables a computer system to detect a ball using computervision algorithm. In this research, the system consisting of a camera and a single board computer. the camera is used to capture an image and the single board computer is used to process the image to get ball position on the image. the ball position information is then processed to map the position of the ball. After that, the information of mapping is sent to the robot controller and process it into a movement. Experiments result show that the robot withthe designed system is function as designed.

On-board image processing for mobile robots provides a vast number of application possibilities in both research and practice. We are interested in the development of small, inexpensive mobile robot systems, incorporating on-board real-time vision systems. Currently, vision-based navigation for mobile robots requires either large robot systems, capable of carrying heavy computer systems, tethered systems, or wireless links to a host system, which computes the image data off-line. Our approach consists of the software tool Improv and the hardware/software robotvision module EyeBot.

3D vision location is one of the most famous researches in computer stereo vision area. However, the traditional algorithm is not only complicated but low-matched. We proposed a new algorithm in this article: First of all, we use Zhang Zhengyou camera calibration methods for vision calibration. Secondly, Epipolar constraint, NCC similarity measure and disparity gradient compatibility are individually used in different stages of sparse feature based stereo matching. the last, least squares space coplanar approximation is used to obtain the 3D coordinates of matching points. It has been proved not only operated easily but provided with high stability and robustness.

the complexity of advanced robotvision systems calls for an architectural framework with great flexibility with regards to sensory, hardware, processing, and communications requirements. We are currently developing a system that uses time-of-flight and a regular video stream for mobile robotvision applications. We present an architectural framework based on YARP, and evaluate its efficiency. Overall, we have found YARP to be easy to use, and our experiments show that the overhead is a reasonable tradeoff for the convenience.

Accidents have been found to be one of the leading causes of both fatal and non-fatal injuries to children. though some accidents that occur are often unavoidable, more often than not these injuries can be prevented by giving the child proper attention. the researchers intend to address certain gaps in stationary monitoring solutions by adding abilities such as an insured way of continuously monitoring the test subject and a real time notification feature to a mobile spherical robot. this research presents the software division of a technological solution to child monitoring by developing a computervision algorithm for following and monitoring children indoors utilizing an RGB-D camera. this algorithm will work hand in hand with a hardware design of a spherical robotthat utilizes microcontrollers, RFID technology and GSM system. An Android application will also be created to provide the users the means of manually overriding the spherical robot, color calibration and location indicator as a part of the robot's notification system. the detection and tracking ability of the algorithm is tested by using objects with varying characteristics. the autonomous navigation testing of the robot is performed at two controlled test setups: living room and child's playroom.

As current liver perfusion machines use pH probes for monitoring the acidity level in their machine, it poses an increased risk of contamination due to the probes direct contact withthe blood, which would then greatly increase the risk of transplant failure. In order to detect pH levels of blood in a liver perfusion machine with minimal contact, this study will use computervision as a tool in detecting and the given ph. In order to determine the pH level of blood, multiple computervision techniques with built in knowledge-based systems will be used in the study. the knowledge-based system will continue to improve overtime as more data is collected. In this study, perfusion liquid will be used as the medium for blood due to ethical concerns. the pH is regulated using fuzzy logic control from the data taken from the pH detection system. through the data taken from the results, it shows that this system when compared to the traditional pH monitoring system is accurate and viable in determining the pH level of the blood. And the system is viable in regulating the pH level of the system effectively.

A time-optimal speed schedule results in a mobile robot driving along a planned path at or near the limits of the robot's capability. However, deriving models to predict the effect of increased speed can be very difficult. In this paper, we present a speed scheduler that uses previous experience, instead of complex models, to generate time-optimal speed schedules. the algorithm is designed for a vision-based, path-repeating mobile robot and uses experience to ensure reliable localization, low path-tracking errors, and realizable control inputs while maximizing the speed along the path. To our knowledge, this is the first speed scheduler to incorporate experience from previous path traversals in order to address system constraints. the proposed speed scheduler was tested in over 4 km of path traversals in outdoor terrain using a large Ackermann-steered robot travelling between 0.5 m/s and 2.0 m/s. the approach to speed scheduling is shown to generate fast speed schedules while remaining within the limits of the robot's capability.
