This letter addresses the problem of trajectory planning in a marsupial robotic system consisting an unmanned aerial vehicle (UAV) linked to ground (UGV) through non-taut tether with controllable length. To best our knowledge, this is first method that UGV-UAV tether. The objective determine synchronized collision-free for three agents: UAV, UGV, and First, we present path solution based on opt...

The study of autonomous planning of UAVs (Unmanned Aerial Vehicles) flyable on-line path to adapt unstructured environment and improve manoeuvring warfare capability has an important practical significance. A path planning algorithm on-line of UAV based on Pythagorean Hodograph (PH) curve is put forward, which can consider the kinematics and dynamic constraints. The effect of the key parameters...

there have been a number of developments in screw design and implantation techniques over recent years, including proposal of an alternative trajectory entitled as cortical bone trajectory (cbt). cortical bone trajectory has been investigated in recent medical treatments as an alternative for screw fixation aimed at increasing purchase of pedicle screws in higher density bone. cbt screw inserti...

We consider the problem of optimal path planning in different homotopy classes in a given environment. Though important in applications to robotics, homotopy path-planning in applications usually focuses on subsets of the Euclidean plane. The problem of finding optimal trajectories in different homotopy classes in more general configuration spaces (or even characterizing the homotopy classes of...

Within the Industry 4.0 ecosystem, Inspection Robotics is one fundamental technology to speed up monitoring processes and obtain good accuracy performance of inspections while avoiding possible safety issues for human personnel. This manuscript investigates robotics inspection areas surfaces employing Unmanned Aerial Vehicles (UAVs). The contribution starts by addressing problem coverage path p...

| This paper addresses trajectory planning for a robot subject to dynamic constraints and moving in a dynamic workspace. A car-like robot A with bounded velocity and acceleration, moving in a dynamic two-dimensional workspace is considered. The solution proposed is an extension of the path-velocity decomposition which is a practical way to address trajectory planning in dynamic workspaces. Howe...

High precision 4D flight path predictions are crucial for reliably optimizing the complex ATM/ATC system. The presented enhanced jet performance model provides a significant improvement over currently applied trajectory prediction methods. The use of purely analytical methods allows a high level of adoption of the real physical aircraft environment. This paper presents the model and applies the...
