Node mobility has been exploited in many context of Mobile Sensor Networks (MSNs) and Wireless Sensor and Actor Networks (WSANs) to improve network performance. In particular, network partitioning due to node failures has been addressed via repositioning of some of the mobile nodes. In all of these studies, the application terrain is assumed to be obstacle free and the movements are performed by following...
With improvement in the quality of people's life and the change of their lifestyle, the demand for intelligent water dispensers is increased. This study, therefore, proposes to de-sign a service robot that can not only move autonomously but also serve people intelligently. In this paper, a solution to de-sign an intelligent water-dispensing service robot is proposed. A new integrated system architecture...
This paper brings forward a novel hardware structure system for localization and pose tracking of an Autonomous Mobile Robot (AMR). The system consists of a CPU and four Wireless Sensor Nodes (WSN), i.e. two ultrasonic transmitter nodes and two ultrasonic receiver nodes. Four ultrasonic time-of-flight (TOF) measurements together with the velocity information of an AMR are used to update the AMR's...
Today, most autonomous mobile robots rely on centralized perception and processing. They are, however, facing difficulties to be reliable and efficient due to uncertainties introduced from dynamic environments. In this paper, an intelligent environment with distributed visual sensors to support navigation and control of mobile robots, wireless mosaic eyes, is reported. The distributed visual sensors...
With the implementation of sensors and actuators into buildings, spaces therefore have sensing ability, flexibility, and interactivity. Moreover, there is also the ability of auto-transformation in space depending on weathers and habitants' needs and behaviors, which overthrows the traditional motionless building space concept. A space is considered as a huge robot, and every space cube is constituted...
Path finding by multiple robots has been studied by many researchers. In particular, when the robot is able to communicate with other colleague robots, path finding will be solved collaboratively among the robots. The main motivation of this article is to apply wireless multihop communications to the collaborative path-finding problem. For this purpose, we propose a cooperative path finding algorithm...
Generally self-organization of the active sensor networks is moving a collection of robots from an area to desired area. When the robots reach the designated area in a network with a topological structure different from the desired one, reconfiguration of the sensor network must be performed by changing the topological structure. During the reconfiguration process, we need to ensure that each robot...
In an indoor robot navigation system, as wireless sensor nodes have limited memory capacity and computing power, generally it is impossible to store routing information or overall geographic information in the nodes. This design adopted Bloom filter to compress route information so that large amount of data path information can be stored in a distributed way in the wireless sensor notes. This study...
This paper presents the development of a mobile robot platform, That can be use in offices and commercial environments. Thus the ability of a robot to plan motions autonomously is of importance. This work gives a new intelligent control of a wheeled mobile robot motion in an unknown environment. The technique generates satisfactory real time movements of autonomous robot to reach its goal safely.

In particular, when the robot is able to communicate with other colleague robots, the path-finding will be solved collaboratively among the robots. Main motivation of this paper is to apply the wireless multihop communication to the collaborative path-finding problem. For the purpose, we propose an algorithm called CPA (Cooperative...
