In this paper, we develop a rescue robot that searches for the victim in the disaster scene. To go into a narrow space in such a scene, size of the robot should be small. But the ability to pass over the trench and the rubble is important. We propose the crawler type robot which has the expandable side crawler. This mechanism can enlarge the mobility of the robot by expanding the side crawler when it is necessary. And this rescue robot pass the rubble by using the side crawler as the arm. So that the swing mechanism for the side crawler is also installed. Details of the developed robot and several experiments are denoted in this paper.
In this paper, a novel approach is presented to calculate the lumped parameters of right/left-handed Structures. By this method, the equivalent circuit can be extracted, and the left/right handed features can be certi...

The demand on distribution network reconfiguration abilities is increasing. This paper proposes a Finite State Automaton model of a distribution network that deals with topologically safe reconfiguration. Autonomous operation of distribution networks can be designed, analysed and implemented in day-to-day operation with the aid of these automata: through supervisory control. Two approaches to supervisor design are proposed. One for the normal operating mode and the other for the contingency mode. Simple and comprehensive examples illustrate the approaches.

The IEEE 802.16 standard which has emerged as a broadband wireless access technology, promises to deliver high data rates over large areas to a large number of users in the near future. We present a simple analytical method for VoIP capacity estimation in IEEE 802.16e mobile WiMAX networks. Various overheads that impact the capacity are explained and methods to reduce these overheads are also presented. The analysis process helps explain various features of mobile WiMAX. It is shown that proper use of overhead reducing mechanisms and proper scheduling can make an order of magnitude difference in performance. The paper gives the maximum number of voice sessions using multiple VoIP codecs. Via simulation using ns2, the results of the analytical calculations will be validated using simple scheduler.
