We present a new method for local obstacle avoidance by indoor mobile robots that formulates the problem as one of constrained optimization in velocity space. Constraints that stem from physical limitations (velocities and accelerations) and the environment (the configuration of obstacles) are placed on the translational and rotational velocities of the robot. The robot chooses velocity command...

In this article, we present a Q-learning-enabled safe navigation system-S-Nav-that recommends routes in road network by minimizing traveling through categorically demarcated COVID-19 hotspots. S-Nav takes the source and destination as inputs from commuters path for traveling. The system dodges hotspots ensures minimal passage them unavoidable situations. This feature of reduces commuter's risk ...

Dynamic implant navigation system (DINS), a novel technology that has revolutionized the field of dentistry. DINS is computer-guided uses three-dimensional imaging and real-time feedback to aid in placement dental implants. The offers improved accuracy, safety, efficiency compared traditional techniques. This review article discusses principles components DINS, its clinical applications, advant...

This paper presents a novel navigation architecture for automated carlike vehicles in urban environments. Motion safety is a critical issue in such environments given that they are partially known and highly dynamic with moving objects (other vehicles, pedestrians. . . ). The main feature of the navigation architecture proposed is its ability to make safe motion decisions in real-time, thus tak...

Using reasonable and efficient autonomous technology for path planning can effectively improve the safety of ship navigation and can reduce human errors of maritime accidents. The planned path by A* algorithm is flawed with broken lines, many turning points and numerous transitional frequencies under the environment modeled by grid method. Smoothing A* algorithm is adopted to delete the removab...

We present a novel robot social-aware navigation framework to walk side-by-side with people in crowded urban areas in a safety and natural way. The new system includes the following key issues: to propose a new robot social-aware navigation model to accompany a person; to extend the Social Force Model, “Extended Social-Force Model” (ESFM), to consider the person and robots interactions; to use ...

In the paper the Author, a member of the International Maritime Organization’s Correspondence Group on e‐Navigation, outlines the prioritized solutions for e‐Navigation concept formulated at the beginning of 2013. He presents the details of internal CG’s discussions, different national positions after the announcement by the chairman of the group, Mr John Erik Hagen, the ...
