Abstract

This study presents the algorithm for a humanoid robot to accomplish an obstaclerun in the FIRA HuroCup competition. It includes the integration of imageprocessing and robot motion. DARwIn-OP (Dynamic Anthropomorphic Robot withIntelligence–Open Platform) was used as the humanoid robot, and it isequipped with a webcam as a vision system to obtain an image of what is in frontof the robot. Image processing skills such as erosion, dilation, andeight-connected component labeling are applied to reduce image noise. Moreover,we use navigation grids with filters to avoid the obstacles. Fuzzy logic rulesare used to implement the robot’s motion, allowing a humanoid robot toaccess any routes using obstacle avoidance to perform the tasks in theobstacle-run event.
