Abstract In the face of a complex battlefield environment, multi-dimensional dynamic planning algorithm is proposed to solve trajectory problem cooperative flight mission process unmanned aerial vehicles. Under constraints aircraft kinematics, collision between and space-time cooperation, under influence random wind field, threat area, other interference factors, can make UAV group pass through...

An essential task of UAV autonomy is automatic path planning. There are many evolutionary planners for Unmanned Aerial Vehicles (UAVs) that have been developed UAV community. In this paper a comparative study about performance of effective trajectory planners is done. Also an efficient version of black hole methodology has been introduced for single UCAV trajectory planning, and an enhancement ...

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...

VII. CONCLUSION In this paper, optimal path planning for robot manipulator is presented that utilizes a variational technique. A simplified robot arm is considered to facilitate geometric collision checking scheme. This is incorporated in the variational technique to develop a collision avoidance strategy. The collision checking scheme is rather stringent. However, it reduces the computational ...

This paper is concerned with the dynamic motion analysis and the planning of maximum payload path of flexible manipulators. The finite element method was employed for dynamic modelling of the system and the motion of the model was considered as a combination of the rigid displacement and the elastic deformation of each link. Each manipulator link was treated as a finite number of elements and t...

This paper presents how a problem of optimal trajectory planning, that is an optimal control problem, can be transformed into a parametric optimization problem and in consequence be tackled using efficient deterministic or stochastic parametric optimization techniques. The transformation is done thanks to discretizing some or all continuous system’s variables and forming their time-histories by...
