This paper deals with dynamic network connection and communication of multi robot control. Communication between each robot is very important to control multi robot. In this research, JAUS that is made by department of defense is used to control robot. This robot has GPS and wireless communication device that is a network router. It can connect several network routers and make a network group. In...
A navigation algorithm is very important on UGV. So, in this research, we propose the algorithm of navigation method by using RTK-GPS units and encoders. GPS systems sometimes lose their signals and receive inaccurate position data due to many factors, such as obstructions. This paper shows that GPS failure can be solved by using a DR navigation method with encoders and that position errors can be...
This paper introduces an optimal algorithm through analyzing and studying various algorithms used in DARPA Urban Challenge 2007 and making a numerical statement about each algorithm. The top eleven teams that passed the NQE (national qualifying event) used Dijkstra, A*, RRTs, and D*. Therefore, this research will focus on those algorithms and study a method to apply an optimal algorithm.
This paper shows a method of multiple communicate to connect each of distributed levels of developed unmanned system according to the JAUS protocol. Each of distributed levels of the JAUS protocol divides into a system, some of subsystems, nodes, and components/instances, each of which may be independent or interdependence. Each of levels must require a method of communication to process data with...
This paper deals with the peer-to-peer data communication to connect each of distributed levels of developed unmanned ground vehicle (UGV) according to the JAUS protocol. Each of distributed levels of the JAUS protocol divides into a system, some of subsystems, nodes, and components/instances, each of which may be independent or interdependence. Each of levels must require high performance to process...
