Autonomous Cross-Country Navigation requires a system which can support a rapid traverse across challenging terrain while maintaining vehicle safety. This work describes a system for autonomous cross country navigation as implemented on the NavLab II, a computer-controlled off-road vehicle at Carnegie Mellon. The navigation software is discussed. The perception subsystem constructs digital maps...

This paper presents a whole swarm system for low-cost visual navigation, developed to participate in the 2013 IMAV Indoor Flight Competition. The quadrotor platform employed is the Parrot ARDrone 2.0. ArUco Codes [2] are used to sense and map the obstacles and to improve the pose estimation based on the IMU data and optical flow by means of an Extended Kalman Filter localization and mapping met...

This paper researched on change detection of outdated map road feature based on updated high-resolution satellite remote sensing (RS) image. The change of road feature was divided into two parts: one is disappear or partial change; the other is new added. To detect disappear or partial changed road, based on outdated map road feature, this paper put forward methods of multi-scale template match...

SAUSAGES stands for System for Autonomous Specification, Acquisition, Generation, and Execution of Schemata. SAUSAGES provides a framework for specifying, running, monitoring, and altering plans for mobile robots, and is ideal for building complex real-time systems that need to operate outdoors. SAUSAGES bridges the gap between planning and action, between the world of symbols and propositions ...

in the last few years, public awareness has been on the increase about short- and long-term effects of forest roads construction on the environment. therefore, forest road managers have to be concerned about the negative impacts and mitigate them as much as possible. this research conducted multi-criteria analysis techniques in a useful way to define the effective criteria and propose a model f...

We study an important practical aspect of the route planning problem in real-world road networks – maneuvers. Informally, maneuvers represent various irregularities of the road network graph such as turnprohibitions, traffic light delays, round-abouts, forbidden passages and so on. We propose a generalized model which can handle arbitrarily complex (and even negative) maneuvers, and outline how...
