# ekf_localization_node and ukf_localization_node both use a 3D omnidirectional motion model. If this parameter is # set to true, no 3D information will be used in your state estimate. Use this if you are operating in a planar # environment and want to ignore the effect of small variatio...
Finally, the skeuomorphic pattern is based on an interface design that uses a model or metaphor of something from the real world. This is a trend that means digital designs resemble their nondigital counterparts. Currently in disuse, the skeuomorphic digital interfaces resemble the real objects that...
in a small area, an evasive action taken to avoid a collision may endanger other ships. This problem has beenalleviatednear busy seaports by confining incoming and outgoing ships to separate lanes, which are clearly marked and divided by the greatest practical distance. Airplanes travel so fast ...
Navigation is a fundamental task for agricultural robots. Performing this task requires determining where the robot is (point A), where it needs to be (point B), how it should get to B (path in an unstructured enviroment from A to B), and how to deal with environmental factors and conti...
Q-CTRL, a developer of quantum infrastructure software, announced successful field trials of a new generation of quantum-assured navigation solutions validated to outperform comparable conventional alternatives in challenging real-world settings. Read More > ...
Navigation mesh is a technique to represent a game world using polygons. Due to its simplicity and high efficiency in representing the 3D environment, navigation mesh has become a mainstream choice for 3D games. According to the number of sides of polygons, navigation mesh can be categorized in...
Spaceflight, flight beyond Earth’s atmosphere. This article deals with the basic concepts associated with the launch and return of unmanned and manned spacecraft and their travel, navigation, and rendezvous and docking in space. For the development of s
Angle-based PLAN solution can typically provide high accuracy (e.g., decimeter-level) in a small area (e.g., 30 m by 30 m) (Quuppa2020). The challenge is that AoA systems require specific hardware (e.g., an array of antennae and a phase-detection mechanism) (Badawy et al.2014),...
