CLARAty: Coupled Layer Architecture for Robotic Autonomy

CLARAty is a unified and reusable robotic autonomy architecture that provides basic functionality and simplifies the integration of new technologies for future missions. It has two layers: a Functional Layer and a Decision Layer. The Functional Layer provides the basis set of functionality for the robot, and encapsulates this functionality into nested levels of granularity when appropriate. The Decision Layer is a model-based representation of the system and interacts with the Functional Layer at various levels of granularity. The Decision Layer is the home for artificial intelligence software components.

CLARAty is a collaborative effort of two divisions at JPL, NASA's Ames Research Center (ARC), and Carnegie Mellon University (CMU). It also draws on expertise from participants within the Mars Technology RMSA Program, which includes the University of Washington and other groups at CMU and ARC.

GESTALT

Grid-based Estimation of Surface Traversability Applied to Local Terrain. This is a derivative algorithm of CMU-developed navigation software called Morphin. GESTALT uses stereo images of the terrain immediately in front of the rover to analyze the "goodness" of possible driving directions, ranging across the spectrum from severe left turns through severe right turns. Goodness is based on terrain geometry, roughness, confidence in stereo range data, and other factors. Driving direction decisions may also be weighted with knowledge of the desired goal direction.
