Mapping Gaps in Sugarcane Fields Using UAV-RTK Platform

Mapping Crop Planting Quality in Sugarcane from UAV Imagery: A Pilot Study in Nicaragua

Sugarcane is an important economic resource for many tropical countries and optimizing plantations is a serious concern with economic and environmental benefits. One of the best ways to optimize the use of resources in those plantations is to minimize the occurrence of gaps. Typically, gaps open in the crop canopy because of damaged rhizomes, unsuccessful sprouting or death young stalks. In ord...

UAV Collision Avoidance Using Artificial Potential Fields

Over recent years, research into Unmanned Aerial Vehicles (UAVs) has increased substantially. However, if autonomous flight of these vehicles is to become feasible in the near future, a collision avoidance scheme must be developed to ensure airspace safety. In this paper, we propose a novel artificial potential field approach to this problem, which, combined with a powerful priority-based syste...

Dexterous Hexrotor UAV Platform

Mobile manipulation is a hot area of study in robotics as it unites the two classes of robots: locomotors and manipulators. An emerging niche in the field of mobile manipulation is aerial mobile manipulation. Although there has been a fair amount of study of free-flying satellites with graspers, the more recent trend has been to outfit UAVs with graspers to assist various manipulation tasks. Wh...

Relative Positioning with RTK Filtering and PPP FILLING THE GAPS

UAV cooperative data processing using distributed computing platform

Unmanned Aerial Vehicles (UAV) are being increasingly used in growing number of applications. The use of single vehicle is often not enough due to various limitations, such as available power or sensors installed. Therefore the UAVs are formed into cooperative teams that operate as the distributed processing system realizing the given mission with one or more objectives (tasks) defined. The key...
