With the advancement in mechatronics era the wireless communication will play a vital role in robotic applications. Many researchers are focusing to develop the rope climbing robots (RCR). This paper discussed the horizontal movement of the rope climbing robot. The method adopted to RCR results reliable values to meet the challenges of the military operations. The rope-climbing robot that can cling to a rope for locomotion has been a popular equipment for some inspection applications due to its high flexibility. In this study, a modular rope-climbing robot with the finger-wheeled mechanism is proposed. Due to the ingenious finger-wheeled mechanism and the modular structure, the robot can achieve smooth and quick movement and good capability of obstacle-crossing on the rope and has a high adaptability for different rope environments.
