Item type:Publication, Optimal bumping avoidance for snake-like robot's serpentine movement controlling(2007-12-01)This paper shows the development of controlling system of snake robot's movement in order to make the Serpentine movement more effective when it goes into narrow path. Snake robot consists of many servo motors serially linked to each other and has its length like a medium-sized snake's. This controlling system measures the side lengths, which are inputs, from the sensors attached on the head of the robot. The robot then processes the inputs and uses them to control the width of crawling in order to perform the crawling at the best speed on limited path. The ways to control it to move forward, backward, left, right, and algorithms used to control are already explained. The result of this experiment, which is an achievement of movement in different locations, shows that it works effectively. © ICROS. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, A geno-hydra control system: Design and tuning hybrid controller based on hydra control structure by using genetic algorithms(2006-12-01) ;Sanornoi, Nitiwat; ;Sritheerawirojana, UthaiThis paper shows how to design the hybrid control system based on hydra control structure by introducing two design strategies which are as following: Double head and Line up. These two strategies use Genetic Algorithms to improve parameters in control system and they also situate the Challenge and Best-selection processes which are the methods to compare the efficiency of the system after they have been genetically calculated. In order to select an appropriate control system in each layer, the simulation's results in the end will show the test with Non-linear plant to show the efficiency of control system after it has been developed by designing and tuning process. © 2006 IEEE. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, A new analog control circuit design for hexapod using cellular neural network(2004-12-01) ;Maneesilp, Kraimon; This paper presents a new design of Cellular Neural Network for controlling hexapod robot Movement on forward motion. It shows a set of new state equations which higher propagation than the original one. These new equations reduce number of CNN pattern generation cells from 12 to 6 cells. As a result, this provides a new technique for designing CNN analog control circuits which can be reduced circuit components and simplified the system architectures. © 2004 IEEE. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Inset dual U-strip slot antenna fed by microstrip line for WLAN applications(2008-12-01) ;Archevapanich, T. ;Nakasuwan, J.; ;Anantrasirichai, N.Sangaroon, O.This paper presents the slot antenna fed by microstrip line with inset U-strip for dual frequency operates in WLAN applications. The rectangular slot antenna is proposed for comparison between with and without U-strip in slot antenna by using three configurations of slot antenna. This antenna is designed for dual frequency used in WLAN system coverage IEEE 802.11b/g (2.4-2.4835 GHz), IEEE 802.11J (4.90-5.091), IEEE 802.11a (5.15-5.35 GHz) and WiMAX of IEEE802.16d (5.7-5.9 GHz). The PCB-FR4 substrate with dielectric constant (ε<inf>r</inf>) 4.5 of thickness 1.6 mm is chose for low cost. The simulation results of these slot antennas are analyzed by using Method of Moment (MoM) from IE3D Software. Finally, the result of bandwidth at low frequency and high frequency of the desirable antenna are 9.76% and 31.6% at frequency range 2.3-2.58 GHz and 4.76-6.34 GHz, respectively. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Implementation of facial visualization for robotic indicator by using fuzzy emotion system(2007-12-01); Archevapanich, TuanjaiThis paper shows the result of the [1] experiment and shows how to design and status of the robot in Face emotion. We implement with the a vacuum robot, and we will show how to setup the system into hardware, which consists of Fuzzy Emotion Generator that processes the inputs from the heat sensors of the main board and the battery indicator to the outputs for using in visualization step which is a displaying board. Visualization has been developed to show the robot's emotion through the face completely by limited hardware. The result of the experiment of showing the emotion through the face of the robot works naturally. ©ICROS. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Compact CPW-Fed wide slot antenna for ultra-wideband applications(2009-01-01) ;Kueathaweekun, W.; ;Benjangkaprasert, C. ;Anantrasirichai, N.Wakabayashi, T.A compact ultra-wideband (UWB) CPW-fed slot antenna design is presented. The antenna consists of a wide rectangular slot on the ground plane with rectangular-ring shaped tuning stub. The simulation result of the impedance matching for the proposed antenna show the impedance bandwidth, determined by-10 dB return loss of 116 %, coverage 2.94 GHz to 11.06 GHz for UWB applications. The simulation radiation patterns and gain of the antenna at different operational frequencies are presented and discussed. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Study on microstrip line fed rectangular slot antenna for widen bandwidth(2009-01-01) ;Achevapanich, T. ;Arsusiri, N.; ;Sangaroon, O.Anantrasirichai, N.The simple rectangular slot antenna fed by microstrip line is design and use as an original antenna for study on the various shapes of tuning stub for widen bandwidth. The tuning stub is design at the end of the microstsrip line on the other side of slot antenna. The shape and size of tuning stub will affect to the bandwidth, the adjustment parameters dimension of stub can achieve desirable bandwidth. The bandwidth of the original antenna without stub is 0.5 GHz from frequency range 2.24-2.74 GHz. In this paper, we proposed the four shapes of tuning stub for achieved either single widen bandwidth or dual widen bandwidth use in wireless communications. The bandwidth of slot antenna is expanded more than 1 GHz up to 7 GHz depend on the shape of tuning stub and its parameters.
