Because of the smart design with few numbers of actuators, smaller in size and weight, lower power having simplified controller and modest price make the humanoid robot kits more attractive, charismatic and representable to the general public. In this paper the small sized biped robot called TODDLER is delineated intricately. The paper also exemplifies the design strategies of a novel walking gait for this robot kit. A new control architecture is also proposed and designed based on PIC 16F877A which makes the biped system more valuable for educational activities on robotics research especially for humanoid robots. A rudimentary algorithm, that helps the biped kit to perform its gait to navigate, is represented and its simulated results are also scrutinized in this paper.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133069053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ECT can be used for imaging industrial multi-component processes involving nonconducting fluids and solids in pipelines. The electrical capacitance sensor is a non-invasive device that uses non-intrusive technique to measure the concentration of flow inside a closed pipe by measuring variations in the dielectric permittivity of the material. The capacitance of the sensor changes when the mean dielectric constant between the electrodes varies due to variations in the percentage of gas and liquid flowing in the pipe. The acquired concentration profile that obtains from capacitance measurements is able to imaging liquid and gas mixture in pipelines, meanwhile the system development is designed to attach on a vessel. The electrode plates which act as the sensor previously has been assemble fixed on the pipeline, thus it causes difficulty for the production to have any new process installation in the future. Therefore on-board sensing plate offers a new design and idea on ECT system which is portable to be assembled in different diameter sizes of pipeline, and it's flexible to apply in any number due to different size of pipeline without redesign the sensing module. The on-board sensing plate development contains signal conditioning circuit and sensing electrode built in a single module (embedded on single plate). In this paper, the details on fabricating the sensors electrodes, had been described, including signal conditioning circuit/electronic part of measurement, such as stray immune capacitance measurement circuit, amplifying circuit, AC to DC converter circuit and filter circuit.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130218270","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the surveillance mode INDERA continuously transmits modulated electromagnetic waves to detect targets in the surrounding area. Since the transmitted signal is a continuous wave, INDERA needs only a very small power to transmit its signal. Consequently, the level of signals arrived on the Rx-antenna part is also very low. The frequency of the transmitted signal is varied with time. As a result, the signal reflected by a target will generate a beat signal with a frequency proportional to the target distance. Thus basically we can compose a two-dimensional image from such signals. In this paper we present a method to reconstruct a 2D radar image from the signals received by radar INDERA.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133985058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the recent trend is a drive to support mobility of the entire network (Network Mobility — NEMO). NEMO provides mobility solution based on Mobile Router (MR) concept. The mobile routers maintain session continuity between the Mobile Network Nodes (MNNs) and their Corresponding Nodes (CNs) irrespective of the MR's change of point of attachment. Specifically with NEMO Basic Support protocol, all data packet to or from MNNs must go through the (MR-HA) via bidirectional tunnel (BDT). Thus, the Home Agent (HA) is a critical element for communications between MMNs and its CNs. However, BDT generates sub-optimal and inefficient routing path thereby, increasing the path length and delay. Furthermore, multiple MRs can be connected together (two NEMOs or more) to form nested NEMO, but the network performance suffers the Pinball routing problems, due to different levels of IP encapsulations. Therefore, this paper aims to describe the issues of the Route Optimization (RO). Furthermore, it presents highlights of different scenarios of NEMO RO and analysis of the corresponding proposed solutions.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116445442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Video conferencing, voice over IP (VoIP), and video on demand (VoD) are examples of real-time applications. These applications require some degree of resource assurance in order to operate effectively. Vast and diverse user requirements create the need for service providers to offer different levels of services in the Internet. Therefore, the Internet community has developed a number of new technologies to address these issues. Differentiated Service (DiffServ) is one of them that has endorsed by Internet Engineering Task Force (IETF) as a scalable solution to satisfy the requirements of new application. In fact, it is anticipated that more mobile users will be connected to the Internet rather than PCs users. The mobile users are interesting to get similar QoS in mobile terminals as in fixed terminals (wired networks) in order to run real-time applications. MIPv6 protocol doesn't provide QoS guarantees to its users same as traditional Internet IP. This poses a problem to real-time applications that required QoS guarantees. Thus merging mobility with QoS is still ongoing research by the networking researchers. To achieve seamless handover and delivery of realtime traffic in mobile environment, DiffServ model is deployed in MIPv6 network. This paper presents an overview of integrating DiffServ in mobile environment. It also proposes a new scheme (DiffServ-MIPv6) to fulfill the needs of both QoS guaranteed and mobility in communication. The proposed scheme intends to reduce handover latency for the mobile node as well as alleviates packet losses.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130061867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vehicle vertical position is maintained by using an inflated air-cushion system attached with the vehicle. It is desired that the vehicle vertical position be maintained at a desired position so that vehicle obtains sufficient traction control and to propel the driving system. To accomplish this task, it is required that the error between the actual position and the desired position equal to zero, and the differential position rate also be equal to zero. Therefore, the main purpose of this study is to develop an appropriate control strategy for an air-cushion system by using fuzzy logic expert system. Air-cushion system is controlled by the electronic proportional control valve and fuzzy logic controller (FLC) with associating the output signal of the distance (height) measuring sensor attached with the vehicle. In this control scheme the fundamental goal is to employ the fuzzy logic expert system to set the fuzzy rules and to actuate the electronic proportional valve in order to obtain appropriate valve control actions. Experimental values are taken in the laboratory for control system testing to investigate the relationship between vehicle vertical position and air-cushion system.","PeriodicalId":376337,"journal":{"name":"2011 4th International Conference on Mechatronics (ICOM)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124451440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
