Design of a laser navigation system for substation inspection robot

Aimed at the deficiency of the magnetic guide and RFID parking system used by substation inspection robot now, a laser navigation method is introduced, and a prototype laser navigation system is designed based on NAV200. The whole structure of the navigation system is presented; the data processing and navigation control algorithm are also described in detail. In order to verify the repetitive precision of the system, an experimental test has been carried out in a 500KV outdoor substation. Experimental results show that the laser navigation system works well, and the repetitive precision of navigation control is precise enough to help the robot fulfill inspection tasks.
