Indoor Navigation for Unmanned Aerial Vehicles
The ability for vehicles to navigate unknown environments is critical for autonomous operation. Mapping of a vehicle’s environment and self-localization within that environment are especially difficult for an Unmanned Aerial Vehicle (UAV) due to the complexity of UAV attitude and motion dynamics, as well as interference from external influences such as wind. By using a stable vehicle platform a...
متن کاملNavigation of Aerial Platforms on Titan
Future missions to Saturn's giant atmosphere-shrouded moon Titan may involve aerial platforms such as airships or helicopters. A significant challenge is the navigation of such vehicles, both in terms of global position determination and path planning in the zonal wind field, and for local stationkeeping to acquire organic surface samples of astrobiological interest. This paper overviews the Ti...
متن کاملEvolved Navigation Control for Unmanned Aerial Vehicles
Whether evolutionary robotics (ER) controllers evolve in simulation or on real robots, realworld performance is the true test of an evolved controller. Controllers must overcome the noise inherent in real environments to operate robots efficiently and safely. To prevent a poorly performing controller from damaging a vehicle—susceptible vehicles include statically unstable walking robots, flying...
متن کاملMeteorology and Agroforestry Meteorology and Agroforestry
The physical environment affects and interacts with agroforestry systems through tree and crop growth, animal performance, management operations and interactions between the tree/shrub and non-tree components (abbreviated to tree/crop interactions). Interactions take place mainly through the media of microclimate, soil moisture and soil. They may have beneficial or adverse effects, for tree and...
