Autonomous navigation to provide long-distance surface traverses for Mars Rover Sample Return Mission
C.N. Shen,G. Nagy +1 more
TL;DR: Knowledge acquisition and representation techniques are developed to allow an autonomous vehicle to negotiate a path over partially unknown terrain, such as the long-distance traverses for the Mars Rover Sample Return Mission.
Autonomous Navigation for Mobile Robot Vehicles Over Hilly Terrain Using Rangefinding Measurements.
TL;DR: In this paper, a laser rangefinder is chosen as principal sensing device, which can determine radial distances from the vehicle to points of unpredictable hilly terrain surfaces, and the overall procedure conducted for such a design consists of the following interrelated subsystems such as scanning scheme, obstacle detection scheme, terrain slope estimation, and path selection algorithm.

On the bound of covariances and error probabilities for the second residual method
C. Shen,F. Stanley +1 more
TL;DR: In this article, the Second Residual method of the Rapid Estimation Scheme gives lower covariances, and consequently has smaller false-alarm and miss probabilities, in comparison with the one dimensional Laplacian method.

Fusion of gross satellite sensing and laser measurements by skyline map matching for autonomous unmanned vehicle navigation
Chi Neng Shen,Lance A. Page +1 more
TL;DR: In this article, two elevation maps are used: a gross terrain map from aerial surveying or satellite observations, and a local measurement map observed with sensors onboard the vehicle for path selection purposes.
