Disasters are increased in number. No matter what the cause of the disaster is human or natural, the consequence is always hard and takes long time to deal with if only human labor is used. Robotic systems are used more and more in search and rescue mission to shorten the time as well as reduce the danger for human. Mobile robot system faced difficulties of uncertainties in sensor system, unstructured...
Over past few decades, the society has seen the stunning transformation of low birth rate and dual-earner households. As a result more and more robots are design for helping people at home. However, most of them are design for specific tasks. This paper proposed an intelligence service robot aim to cope with wide range application in home. To let the robot move freely in home environment and reach...
The autonomous navigation of the mobile robot in an unknown, unstructured and dynamic environment is one challenging problem. An intelligent behavior control system based on fuzzy logic algorithm is proposed for an autonomous mobile robot to traverse through various terrains as slope, maze, and dynamic obstacle and dock station. A hierarchical structure consists of the main high-level navigation controller...
There has been an increasing interest in remote sensing and analysis of the environment. The applications include disaster monitoring, exploration, and natural resource protection. However, the human operation is labor intensive, time consuming and hazardous. The sensors fixed on-site in the environment suffer from limited sensing coverage and still requires human's on-site installation and maintenance...
With rapidly changing of technology, there are more and more robotic applications in household security. Security patrol with human in charge is high labor cost as well as shortage of human resource. Mobile robot can solve some of these problems but it faced difficulties of uncertainties in sensor system, unstructured environments, or lack adaptive ability to situation and dynamic environments. This...
World Health Organization estimated that over 1 billion people are living with some form of disability. Some 110 to 190 million people live with significant disabilities. The number of guide dogs is far lower than the demand and only few visually impaired have access to qualified guidance dogs. This paper present an autonomous mobile robot system aimed for the service to the blind. The system includes...
A considerate amount of literature has been published on small and low altitude aerial mobile robot navigation. The autonomous tasks include trajectory tracking, hovering, goal seeking, object approach, formation keeping and landing etc. Many algorithms have been proposed to navigate the aerial robot in the uncertain, unstructured and dynamic environment. However, how to emulate the actual aerodynamic...
The time delays on the networked control system and the sensor uncertainties are the major factors affecting the performance of the autonomous mobile robot navigation in an unstructured, unknown and dynamic environment. A hierarchical, decentralized and networked control system is proposed that consists of a high-level navigation control module and a remote low-level closed-loop motion control module...
