چکیده

This paper demonstrates the successful autonomous classification of rotary laser scanner data retrieved by an autonomous robot traversing a sewer pipe system. Rotary laser scanner serve dual purposes of fault detection and navigation. The present aim was to devise a robust landmark detection method for use in the robot’s navigation system. A standard feed forward neural network with 6 hidden neurons was trained on the first 15 principle components of the combined amplitudes of the reflected signal and distance values data. The overall system shows a 89% performance for the classification for the validation data as opposed to 79% of a linear neural network. These results demonstrate that the appropriate application of conventional sensor feature extraction, and classification methods may be used to quickly build an effective and computationally efficient landmark detection system for a mobile robot.

On Vision-Based Orientation Method of a Robot Head in a Dark Cylindrical Pipe

This paper addresses the problem of navigation of an autonomous robot when it moves in a modern concrete sewer. The robot must keep its orientation within mostly cylindrical sewer pipes. This implies a geometrical constraint on the environment in which the robot operates. We present a hybrid vision system that consists of (a) an optical camera and (b) a laser crosshair projector generating a cr...
