Reactive Navigation Under Non-Parametric Uncertainty Through Hilbert Space Embedding of Probabilistic Velocity Obstacles [PDF]
IEEE Robotics and Automation Letters, 2020 The probabilistic velocity obstacle (PVO) extends the concept of velocity obstacle (VO) to work in uncertain dynamic environments. In this paper, we show how a robust model predictive control (MPC) with PVO constraints under non-parametric uncertainty ...

Efficient Local Navigation Approach for Autonomous Driving Vehicles
IEEE Access, 2021 This paper presents an efficient and practical approach for a car navigation system (CVM-Car) based on the velocity space optimization paradigm. The method calculates the velocity control commands to keep the car in the lane while avoiding the obstacles ...

A classification of on-road obstacles according to their relative velocities [PDF]
EURASIP Journal on Image and Video Processing, 2016 The systems based on image processing have numerous applications in the domain of motion control of robots and autonomous vehicles. The current paper is oriented to the solution of the problem that precedes the implementation of automatic avoidance of the on-road obstacles—how to detect them, to track in the sequence of images, and to recognize which ...

Experimental Investigation of the Cubic, Cylindrical, and Pile-shaped Obstacles on the Motion and Control of the Body of Saline Density Current [PDF]
مهندسی منابع آب, 2023 Introduction: The use of obstacles in dam reservoirs is considered an effective method for directing sedimentation toward the middle of the reservoir (instead of sedimentation next to the dam wall where the facilities are located).

Unmanned Surface Vehicle Collision Avoidance Trajectory Planning in an Uncertain Environment
IEEE Access, 2020 Unmanned surface vehicles (USVs) can encounter undetected moving obstacles while sailing along a planned global path. USVs need to plan collision avoidance trajectories for moving obstacles. In this paper, an algorithm based on the Gaussian mixture model

Obstacle Boundary Point and Expected Velocity‐Based Flocking of Multiagents with Obstacle Avoidance
International Journal of Intelligent Systems, 2023 Obstacle avoidance is a key technology of multiagents flocking control. However, most existing research studies assume that the agent can obtain global information about obstacles and have specific constraints on the shape and boundary of obstacles, which easily limit their practical applications.

Collision Avoidance of Multi Modal Moving Objects for Mobile Robot Using Hybrid Velocity Obstacles
International Journal of Intelligent Engineering and Systems, 2020 : Mobile robotic systems must have the ability to guarantee safety for operating in close proximity with other moving objects. This paper aims to develop collision avoidance method based on velocity control with respect to several modal of moving objects

Evading of Pedestrian Pursuer and Avoiding Obstacles Using Path-Velocity Planner
IEEE Access, 2021 The ability to navigate mobile robot from initial to target position while maintaining the safety and comfort of pedestrian have to be supported by a collision avoidance system. In the case of pursuit-evasion when a pedestrian pursues a robot, navigation

IEEE/RJS International Conference on Intelligent RObots and Systems, 2020 Ensuring a safe online motion planning despite a large number of moving agents is the problem addressed in this paper. Collision avoidance is achieved without communication between the agents and without global localization system.

Velocity Obstacle Approaches for Multi-Agent Collision Avoidance [PDF]
Unmanned Systems, 2019 This paper presents a critical analysis of some of the most promising approaches to geometric collision avoidance in multi-agent systems, namely, the velocity obstacle (VO), reciprocal velocity obstacle (RVO), hybrid-reciprocal velocity obstacle (HRVO) and optimal reciprocal collision avoidance (ORCA) approaches.
