TL;DR: A prototype urban robot on a novel chassis with articulated tracks that enable stair climbing and scrambling over rubble and stereo vision-based obstacle avoidance, visual servoing to user-designated goals, and autonomous vision-guided stair climbing is developed.

TL;DR: This paper focuses on the ASV's central perception and situation awareness system, dubbed Surface Autonomous Visual Analysis and Tracking (SAVAnT), which receives images from an omnidirectional camera head, identifies objects of interest in these images, and probabilistically tracks the objects' presence over time, even as they may exist outside of the vehicle's sensor range.

TL;DR: A micro air vehicle that uses vision feedback from a single down looking camera to navigate autonomously and detect an elevated landing platform as a surrogate for a roof top and is able to search autonomously for a landing location and perform precision landing maneuvers on the detected targets.

TL;DR: The design and initial operations of SRR-1 (Sample Return Rover), a novel 10 kg-class four wheel, hybrid composite-metal vehicle for rapid (10 - 30 cm/sec) autonomous location, rendezvous, and retrieval of collected samples under integrated visual and beacon guidance, and development of the FIDO rover (Field Integrated Design and Operations), a new high mobility, multi-km range science vehicle.
