This paper illustrates the implementation of computer vision algorithm for robot localization in completing Free Kick Challenge task of FIRA RoboWorld Cup and Summit. A marker patch is placed at robot's head and robot localization is determined using Roborealm software. Image from marker is processed using color and shape matching technique to estimate position and angle of the robot. Robotis Bioloid Premium robot is used in the challenge task. Robot's controller (CM-530) is interfaced to serial communication in Roborealm software using bluetooth connection using PC to control robot's movement.
