U.S. Army Engineer Research and Development Center researchers manipulate the Robotics for Engineer Operations, or REO, vehicle and quickly capture pertinent data to use for engineer operations during the Maneuver Support, Sustainment and Protection Integration Experiments-2020, or MSSPIX-20, in Fort Leonard Wood, Mo., Sept. 16, 2020. The REO employs a set of robotic platforms to remotely characterize a site by fusing multiple sensing modalities on a fully autonomous unmanned ground vehicle to capture critical information for engineer missions.
