Terrain Classification for a Quadruped Robot [PDF]

2013 12th International Conference on Machine Learning and Applications, 2013
Using data retrieved from the Puppy II robot at the University of Zurich (UZH), we show that machine learning techniques with non-linearities and fading memory are effective for terrain classification, both supervised and unsupervised, even with a limited selection of input sensors.

Terrain characterization and classification with a mobile robot [PDF]

Journal of Field Robotics, 2006
AbstractThis paper introduces novel methods for terrain classification and characterization with a mobile robot. In the context of this paper,terrain classificationaims at associating terrains with one of a few predefined, commonly known categories, such as gravel, sand, or asphalt.Terrain characterization, on the other hand, aims at determining key ...

Lunar Image Classification for Terrain Detection [PDF]

, 2010
Terrain detection and classification are critical elements for NASA mission preparations and landing site selection. In this paper, we have investigated several image features and classifiers for lunar terrain classification. The proposed histogram of gradient orientation effectively discerns the characteristics of various terrain types.
