Mobile robots have been widely implemented in industrial automation and smart factories. Different types of mobile robots work cooperatively in the workspace to complete some complicated tasks. Therefore, the main requirement for multi-robot systems is collision-free navigation in dynamic environments. In this paper, we propose a sensor network based navigation system for ground mobile robots in dynamic...
In this paper, we propose a discrete-time navigation algorithm for a non-holonomic mobile robot. A sensor network, which consists of some range finders, is deployed in a planar environment to detect static and moving obstacles. The robot or a server obtains the real-time local maps from sensor nodes and calculates a temporarily safe path from the robot's current position to a given target. The generated...
In this paper, we propose a safe navigation algorithm for non-holonomic flying robots. To detect the static and moving obstacles, a sensor network, which consists of some time-of-flight cameras, is deployed in a three dimensional environment. The robot or a server obtains the real-time measurements of the environment from the cameras and calculates a temporarily safe robot path from the robot's current...
We present a safe map building and area search algorithm for a mobile robot in a closed unknown environment with obstacles. A range finder sensor is used to detect the environment. The objective is to perform a complete search of the environment and build a complete map of it while avoiding collision with the obstacles. The developed robot navigation algorithm is randomized. We prove that with probability...
