Research on Large Angle Climbing Intelligent Inspection Rail Robot Applied in Hydropower Station Corridors

This paper proposes a new type of corridor climbing inspection robot, aimed at solving the problems of insufficient power and poor stability of existing robots in complex terrain and steep slope environments. The robot adopts a design that combines ground rails with linear transmission bodies, optimizes the automatic walking drive device and multi axis displacement robotic arm, and achieves stable inspection with a maximum climbing angle of over 60°. The robot is equipped with a high-resolution image acquisition device and a supplementary light source, combined with image processing and machine learning algorithms, to automatically identify and classify defects and anomalies during inspection. The experimental results show that the robot does not derail or deviate when climbing a 60° slope, with a minimum turning radius of 1.5 meters, image resolution of 1080p, battery life of 8 hours, stable data transmission, automatic recognition accuracy of over 95%, and maintains stable performance after continuous operation for 1000 hours.
