The Development of Ball Control Techniques for Robot Soccer based on Predefined Scenarios

Robotic soccer is an attractive topic in artificial intelligence and robotics research. However, to develop techniques and algorithms in this domain is a complex task. This study presents the development of ball control techniques and algorithms for robot soccer based on several predefined scenarios. In this study, we study the robot can do ball passing, obstacle avoiding and ball shooting according to certain situations. A vision system is used in this case where it calculates the robot position in x, y coordinates to make sure the robots move to the right direction. The velocity of each robot wheel is manipulated to control the speed of the robots and allow them to make turning and shooting. Algorithm testing was carried out by using a robot soccer simulator. Several techniques in obstacle avoiding and positioning were successfully implemented. The results prove these algorithms can be applied to execute the given tasks. © 2011 Asian Network for Scientific Information

Position and Obstacle Avoidance Algorithm in Robot Soccer

Problem statement: Robot soccer is an attractive domain for researchers and students working in the field of autonomous robots. However developing (coding, testing and debugging) robots for such domain is a rather complex task. Approach: This study concentrated on developing position and obstacle avoidance algorithm in robot soccer. This part is responsible for realizing soccer skills such as movement, shoot and goal keeping. The formulation of position and obstacle avoidance was based on mathematical approach. This formula is to make sure that the movement of the robot is valid. Velocity of the robot was calculated to set the speed of the robot. The positioning theory including the coordination of the robot (x,y) was used to find the obstacle and avoid it. Results: Some simulations and testing had been carried out to evaluate the usefulness of the proposed algorithms. The functions for shooting, movement and obstacle avoidance had been successfully implemented. Conclusion: The results showed its possibility could be used as strategy algorithms in real robot soccer competition

Rekabentuk dan implementasi sistem automasi pembotolan MAPS menggunakan programmable logic controller, PLC

This paper discusses the design and implementation of Programmable Logic Controller (PLC) on Modular Automation Bottling Production System-MAPS. PLC is used for running a system so that it can work automatically and used on repeatable system application. The objectives of using PLC in industry are to minimize production cost, increase productivity, increase quality and system reliable. Design and implementation of this automation system uses MAPS. MAPS is a modular system that was developed by using a few stations into an integrated system. In this research, actual MAPS were used and integrates with other system such as detector, pneumatic, mechanic, electronic and control system
