Traversability Metrics for Urban Search and Rescue Robots on Rough Terrain

January 31, 2007
Author(s)
V Molino, Rajmohan Madhavan, Elena R. Messina, Anthony J. Downs, Adam S. Jacoff, Stephen B. Balakirsky
Rough terrain, such as the rubble that we would expect to find in urban disaster areas, will likely impede robot mobility. The goal of this paper is to find methods for quantifying the difficulty a robot should encounter traversing a region of rough

Combinatorial Coverage Measurement Concepts and Applications

March 22, 2013
Author(s)
David R. Kuhn, Itzel (. Dominquez Mendoza, Raghu N. Kacker, Yu Lei
Empirical data demonstrate the value of t-way coverage, but in some testing situations, it is not practical to use covering arrays. However any set of tests covers at least some proportion of t-way combinations. This paper describes a variety of measures
