Formation Control and Obstacle/Collision Avoidance with Dynamic Constraints

2020
This paper studies the leader-follower formation control problem of unmanned air vehicles(UAVs) flying with dynamic constraints in an obstacle-laden environment. Firstly, formation protocols are presented for UAV swarm systems. Necessary and sufficient conditions for UAV swarm systems to achieve formations are presented based on graph theory.

Utilizing parallax information for collision avoidance in dynamic environments

2008 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2008
This paper studies an active steering problem of unmanned ground vehicles (UGVs) when avoiding obstacles during sensor based navigation in unknown environments. The overall problem is treated using the nonlinear model predictive framework, in which the sensor information of a limited sensing range is incorporated online.

Dynamic obstacles trajectory prediction and collision avoidance of USV

2017 36th Chinese Control Conference (CCC), 2017
This paper focuses on solving the Unmanned Surface Vehicle autonomous dynamic collision avoidance problem. Firstly, a kinematic and dynamics model of three degree of freedom for USV is established, researches USV's treat method about the data of obstacles, and structures whole environment information to make USV avoid obstacles.

Dynamic cooperative perception and path planning for collision avoidance

2009 6th International Symposium on Mechatronics and its Applications, 2009
This paper deals with cooperative path and cooperative perception of Unmanned Aerial Vehicles (UAVs) in dynamic environment. Differential geometry techniques based on Pythagorean Hodographs (PH) are adapted to plan cooperatively path of UAVs in order to avoid obstacles.

Dynamic Motion Planning Algorithm in Human-Robot Collision Avoidance

2019
The collision-free robotic motion planning algorithm in a dynamic environment is an effective method for the prevention of collision in a human-robot interaction scenario. In this paper, an improvement of the Rapidly-exploring Random Tree (RRT) algorithm is proposed to avoid the potential collision between robot and human by taking the costmap of robot
