Collision Avoidance of Moving Obstacles for Underwater Robots

چکیده

A fuzzy logic for autonomous navigation of underwater robot is proposed in this paper. The VFF(Virtual Force Field) algorithm, which is widely used in the field of mobile robot, is modified for application to the autonomous navigation of underwater robot. This Modified Virtual Force Field(MVFF) algorithm using the fuzzy logic can be used in either track keeping or obstacle avoidance. Fuzzy logics are devised to handle various situations which can be faced during autonomous navigation of underwater robot. A graphic simulator based on OpenGL for an autonomous navigation has been developed. The good performance of the proposed MVFF algorithm is verified through computer simulations on an underwater robot.

Mobile Robot Collision Avoidance in Human Environments

Collision avoidance is a fundamental requirement for mobile robots. Avoiding moving obstacles (also termed dynamic obstacles) with unpredictable direction changes, such as humans, is more challenging than avoiding moving obstacles whose motion can be predicted. Precise information on the future moving directions of humans is unobtainable for use in navigation algo...

Data Acquisition of Obstacle Shapes for Fish Robots

It is important to get information about obstacles to avoid collision for a natural and smooth movement for fish robots. In this paper, we propose an IR sensor-based measurement system which gets information about obstacles for underwater fish robots. Due to complexity and space restriction, IR distance sensors are installed instead of cameras or sonar systems. Much importance is given to the n...

طراحی کنترلگر تعقیب مسیر هماهنگ برای گروه شناور زیرسطحی با در نظر گرفتن مسئله اجتناب از برخورد

In this paper the problem of coordinated path following for a group of Autonomous Underwater Vehicle (AUV) subjected to obstacle and collision avoidance is considered. At first a back stepping controller is used for an AUV to design a path following controller and its stability is examined via Lyapunov criteria. Then using of graph theory, modeling of interconnection between AUV systems is addr...

Decentralized & prioritized Navigation and Collision Avoidance for Multiple Mobile Robots

We present an algorithm for decentralised navigation of multiple mobile robots. Completely decentralised Navigation functions build a potential field for each robot that is employed in a feedback control law. The potential field incorporates limited sensing and explicit prioritisation. A non-circular sensing area creates asymmetrical sensing by reducing the influence of robots and obstacles beh...

Vision Based Collision Avoidance of Industrial Robots

This article presents an approach to collision avoidance of industrial robots. It is based on the method of artificial potential or force fields. The field is generated by virtual charges which are placed on obstacles. The virtual force acts on the robot which results in the modification of the manipulator path to avoid collisions. Robot path modification is performed by means of impedance cont...
