Robotic platform for monitoring underground cable systems

摘要

Accurate, real-time information about the aging status of the power distribution cable network can save the power industry millions of dollars lost due to line failures and premature replacement of cables. Hence, a novel, semi-autonomous robotic sensor platform has been developed for monitoring underground, power distribution cable systems. A segmented, legged modular configuration allows the robot to traverse cables with a diameter of four to eight centimeters and negotiate obstacles along its path. The design of platform consists of a multi-processor control board, a 900 MHz wireless communication module, and infrared, dielectrometry, and acoustic sensors. The robot is capable of fully autonomous operation or human tele-operation via a LAN or Internet connection. A prototype platform has been developed and tested with a 14 kV distribution cable. Currently, sensor integration is underway.
