Stepfield Pallets: Repeatable Terrain for Evaluating Robot Mobility

December 31, 2008

Author(s)

Adam S. Jacoff, Anthony J. Downs, Ann M. Virts, Elena R. Messina

Stepfield pallets are a fabricated and repeatable terrain for evaluating robot mobility. They were developed to provide emergency responders and robot developers a common mobility challenge that could be easily replicated to capture statistically

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

Registration of Range Data from Unmanned Aerial and Ground Vehicles
