DEVELOPMENT OF A WIND TURBINE BLADE INSPECTION ROBOT

Abstract

          This research aims to develop a robot for inspecting the operational condition and damage of wind turbine blades. The robot captures images and wirelessly transmits data to ground operators for assessment. The prototype robot is controlled using a Raspberry Pi 4 board, which manages movement via wireless signals and data communication through the Robot Operating System (ROS). Test results indicate that the robot can move on various inclinations and execute programmed functions effectively. It successfully transmits real-time images and records footage. On a flat surface, the movement times
were 0.44 minutes for forward motion, 0.38 minutes for backward motion, 1.19 minutes for left turns, and 1.35 minutes for right turns. On a 20-degree inclined surface, the robot remained operational but required more time compared to a flat surface, taking 9.24 minutes to move forward, 4.26 minutes to move backward, 10.43 minutes to turn left, and 9.31 minutes to turn right. At a 30-degree incline, the robot exhibited limited movement in different directions due to insufficient suction force from the vacuum pump to support its weight. This study demonstrates the robot’s capability in wind turbine blade inspection and provides opportunities for further development to enhance its efficiency in diverse operational conditions.
