First Results in Terrain mapping for a Roving Planetary Explorer

To perform planetary exploration without human supervision, a complete autonomous rover must be able to model its environment while exploring its surroundings. We present a new algorithm to consuuct a geomemc terrain representation from a single range image. The form of the representation is an elevation map that includes uncertainty, unknown areas, and local features. By virtue of working in s...

Robotic Autonomy for Space: Cooperative and Reconfigurable Mobile Surface Systems

We overview some of our recent work on highly autonomous mobile robots for planetary exploration. The work and related system developments address two themes. The first is multi-robot cooperation to perform planetary surface tasks beyond the scope of single robot activity. The second is development of novel mobility architectures and autonomous controls that will enable robotic access to areas ...

Results in Terrain Mapping for a Walking Planetary Rover

Abstmct We present results from a tarain mapping system for walking robots that constructs quantitative models of surface gwmetry. The accuracy of the constructed maps enables safe, powercfficient locomotion over the natural, rugged terrain found on planetary surfaces. The mapping system acquires range images with a laser rangefinder, preprocesses and stores the images, and constructs elevation...

نقشه‌برداری رقومی افق‌های مشخصه و گروه‌های بزرگ خاک در منطقه زرند کرمان

Digital soil mapping includes soils, spatial prediction and their properties based on the relationship with covariates. This study was designed for digital soil mapping using binary logistic regression and boosted regression tree in Zarand region of Kerman. A stratified sampling scheme was adopted for the 90,000 ha area based on which, 123 soil profiles were described. In both approaches, the o...
