The graph-search algorithms developed between 60s and 80s were widely used in many fields, from robotics to video games. The A* algorithm shall be mentioned between some of the most important solutions explicitly oriented to motion-robotics, improving the logic of graph search with heuristic principles inside the loop. Nevertheless, one of the most important drawbacks of the A* algorithm reside...

In this letter, we emulate real-world statistics for mobility patterns on road systems. We then propose modifications to the assumptions of random waypoint (RWP) model better represent high-mobility profiles. call under our new framework as RWP+. Specifically, show that lengths transitions which constitute a trip, are best represented by lognormal distribution, and velocities described linear c...

Agriculture 3.0 and 4.0 have gradually introduced service robotics automation into several agricultural processes, mostly improving crops quality seasonal yield. Row-based are the perfect settings to test deploy smart machines capable of monitoring manage harvest. In this context, global path generation is essential either for ground or aerial vehicles, it starting point every type mission plan...

Analysis of quadcopter dynamics and control is conducted. A linearized quadcopter system is controlled using modern techniques. A MATLAB quadcopter control toolbox is presented for rapid visualization of system response. Waypoint-based trajectory control of a quadcopter is performed and appended to the MATLAB toolbox. Finally, an investigation of control using reinforcement learning is conducted.

We consider the common problem of calculating routes from a starting point to a destination through a given space. This process typically involves discretizing the navigational space into a graph of intermediate waypoints linked together through transitions. A search for a solution that fits desired criteria can then be performed. Typical criteria include: minimum distance, minimum transit time...

Flight crews and air traffic controllers have reported many safety concerns regarding area navigation standard terminal arrival routes (RNAV STARs). Specifically, optimized profile descents (OPDs). However, our information sources to quantify these issues are limited to subjective reporting and timeconsuming case-by-case investigations. This work is a preliminary study into the objective perfor...

We define “random trip", a generic mobility model for random, independent node motions, which contains as special cases: the random waypoint on convex or non convex domains, random walk on torus, billiards, city section, space graph, intercity and other models. We show that, for this model, a necessary and sufficient condition for a timestationary regime to exist is that the mean trip duration ...
