Design of Identifying and Provision System of Chess Playing Robot

More and more research on the chess playing robot carried out currently, which focus on the Renju and Chinese chess and so on, a new humanoid chess playing robot constructed in this paper differ from the traditional industrial robot based simple structure chess playing robot, it can deal with two Renju game and one Chinese chess game together, position of chess on the chessboard confirmed by vision identify. Automatic chess identifying and provision system assembled on both Renju and Chinese chess system, after the game over, chessboard overturn firstly, division realized one by one through transmission device and color sensor, chess transmitted to the distribution square, regular array on level plane and vertical lift achieved with three transmission devices perpendicular to each other, chess send to chess playing platform one by one then. Function realization and working principle and construction design of the whole system described clearly by making use of flow chart and solid building, foundation established for later manufacturing and research.

A Chinese Chessboard Calibration Method in Chess-Playing Robot by Machine Vision Sensing

In view of Chessboard calibration in Chess-Playing Robot by machine vision sensing, a new Chinese chessboard calibration method based on external aided planar pattern is given. Introducing the advantages of the international chessboard calibration technology, which can overcome the difficulties of lens distortion imaging and non-orthographic projective imaging in which cases the former calibration methods can’t be used. This method aligns the planar calibration pattern to the chessboard in such a way that we can get the chessboard grid points’ Image-Coordinate-System coordinates by detecting the planar pattern’s corners and obtain the mapping of a group of points’ s World-Coordinate-System coordinates and Image-Coordinate-System coordinates, which is easy to operate and robust to noises. Workpiece location by machine vision methods in industrial application also faces the problems of lens distortion imaging and non-orthographic projective imaging, so it would be beneficial to introduce this method’s idea into industrial areas.

Design and Implementation of a Computer Vision System for an Autonomous Chess-Playing Robot

This work describes a mechatronic system composed by a robot arm that can play chess autonomously. The system is based on an industrial-grade robot manipulator, a computer vision system, and an open source chess engine. Classification algorithms were implemented in order to detect whether a given chessboard square is occupied, and in that case, if the piece is black or white. Such algorithms were compared in terms of their complexity of implementation, execution time and accuracy of predictions. To achieve an uniform illumination of the chessboard, a theoretical model of an LED illuminance curve was used to find the best orientation for each diode using a genetic algorithm. Both the support base for the LEDs and the chess pieces were made using a 3D printer. This implementation demonstrates the capabilities of the proposed vision-based system, whose complexity can be increased in the future for a number of applications.

The Axiomatic Design of Chessmate: A Chess-playing Robot

Successfully completing a project on time is often a difficult task especially when the project is not well defined. This paper demonstrates the application of Axiomatic Design principles to shape and direct a multi-disciplinary project from initial conception to the final tested product. This product is Chessmate: a small robot which plays chess on a physical board. This robot is intended as a telepresence mechanism or for players who are physically challenged. Verifiable requirements were developed at the beginning of the project based upon this top level goal. These Functional Requirements ensured that the team focused on the necessary capabilities of the end product even while working on electrical, mechanical, and software elements in parallel. Construction of a design matrix identified sources of coupling that would require additional effort to avoid delays. Coupling was reduced in software by careful Application Programming Interface (API) and abstraction development. Testing parameters were explicitly stated by the requirements enabling regular validation in both software and hardware. The result was a complete chess-playing system from start to finish in 12 weeks.

Chessboard and Pieces Detection for Janggi Chess Playing Robot

Vision system is an indispensable part of constructing the chess-playing robot. Chessboard detection and pieces localization in the captured image of robots camera are important steps for processes followed such as pieces recognition, move calculation, and robot controlling. We present a method for detecting the Janggi chessboard and pieces based on the edge and color feature. Hough transform combined with line extraction is used for segmenting the chessboard and warping it to form the rectangle shape in order to detect and interpolate the lines of chessboard. Then we detect the existence of pieces and their side by applying the saliency map and checking the color distribution at piece locations. While other methods either work only with the empty chessboard or do not care about the piece existence, our method could detect sufficiently side and position of pieces as well as lines of the chessboard even if the occlusion happens.

This paper presents a chess-playing robot and its control system based on SERCOS. Thanks to Windows NT operating system and RTX real-time extension, the control system is excellent in real-time property. The whole system, supported by a standard IPC hardware platform and a modularized architecture of system software, is open-ended and expansible. In addition, the chess-playing software makes a contribution to the excellent interaction between players and the chess-playing robot.

A chess-playing robot: lab course in robot sensor integration

To obtain practical experience in intelligent robotics, a laboratory course has been developed in which students have to create a chess-playing robot. The system has to detect the move of a human opponent and has to take appropriate action. Beside knowledge about the integration of sensing and control of the robot arm, the students gain experience in working in a team to realize a medium-size project. The SCIL-IMAGE package is used. It runs under UNIX and XWindows. SCIL is a multilevel environment originally developed in image processing for feasibility studies. IMAGE is an image processing package linked to SCIL. The lowest level is formed by a C-interpreter. Using this interpreter, complete C-programs can be developed. Interpreted code can be directly combined with precompiled code from incorporated libraries. If required these programs can also be compiled and linked to SCIL. >
