Remote Control System For Multi Mobile Robot Using A Combination of Computer-Microcontroller Nanang Ismail; Okyza MP; Dimas Widyasastrena
Proceeding of the Electrical Engineering Computer Science and Informatics Vol 2: EECSI 2015
Publisher : IAES Indonesia Section

Various control systems have been used to optimizerobot performance, one of them is to utilize radio wave. The use ofradio wave is very common because they are cheap and easy todeploy. Radio frequency use is also various; some use VHF, someothers UHF for many purposes. One control system for one robot isdefinitely inefficient, therefore a continuous research on robotcontrol system is required to control multi robots with differentradio frequencies using one control system. This research is meantto develop multiple mobile robots using 40 MHz and 315 MHzfrequency within one system controlled by integrated computer andmicrocontroller. The frequency selection represents VHF and UHFfrequency. This research is a prototype for multi robot control.Testing is done with several methods; system interface testing, Lineof Sight robot control system, and robot control system in anobscured environment. System interface testing is done by usingserial port communication to communicate computer with 8-bitmicrocontroller using ASCII. Line of Sight testing exerts maximumrange of 4 meters using 40 MHz, and 10 meters using 315 MHz.Obscured environment testing exerts maximum range of 2.8 metersfor 40 MHz and 13.4 meters for 315 MHz.

Preparing the dialysate temperature to the desiredlevel is a complicated task, since it has a large degree of time delayand nonlinear behaviour. In this work, embedded system fordialysate temperature controller was developed. It is based onimplementation of fuzzy logic controller software on STM32 F4development kit which consits of ARM Cortex M4Fmicrocontroller. The dialysate temperature was controlled byvarying the firing angle of the triac which is connected to theheater. The K-type thermocouple which is connected to AD595CQwas read and compared with the desire dialysate temperature.The fuzzification process was conducted prior to activate the fuzzyinference process. The power of the heater was adjusted based onthe output of the inference process until the desired watertemperatur was achieved. The system had been sucessfullydemonstrated for controlling the dialysate temperature.

Proceeding of the Electrical Engineering Computer Science and Informatics Vol 2: EECSI 2015
Publisher : IAES Indonesia Section

In this paper, the importance of odor localization isexplained. The researchers that investigated the experimentsand applications of odor localization using static sensors, mobilesensors (that were integrated in single robot, multi robot, andswarm robot) are described. However, there are some difficultiesfaced by the researchers in applying the mobile robots in the realsituation, such as: the speed of mobile robots are not as fast asthe odor patches transporting and the use of more than onesensor in mobile robot can make noises or errors. In the future,the plume finding in the uncertain environment and thechallenges mentioned above will be the authors’ consideration.

very year, demanding of spare parts for vehicle isincreasing together to the number of cars, thus spare parts toreplacing faulty component also high demand. Every workshopneed to keep spare parts for replacing breakdown vehicle or someworkshop request spare parts to store it. Base on that, a good spareparts management and storage system is required for effective andfaster service to thecustomer. This paper discuss on the use ofRadio Freqeuncy Identification (RFID) for car engine storage andspare parts management system using RFID technology, because ofits advantages compare to others technology which is no line ofsight required and multiple reading. Every spare parts or enginetagging by an RFID tag which is programmed early with uniqueidentity, then store to a central database for stock and inventorysystem. Testing havebeen conducted an shows reduce on reading performance becauseof most spare parts and engine made from metal material thuseffected to RFID reading performance. A new technique used forRFID tag before tagging which is make some gap from the engineor spare parts to avoid RFID signal absorve by metal material. Theother way is used high gain antenna andRFID reader for faster and powerfull reading. Results showsimprovement on reading distance and performance compare to theprevious tagging technique and tagging placement.

Publisher : IAES Indonesia Section

5G is speculated to transform the mobilecommunications landscape by increasing data rates, latency,coverage and energy efficiency. Radio-over-fiber (RoF) provides ahigh-capacity, efficient and scalable 5G architecture fortransporting radio signals through optical fibers, exploiting theenormous bandwidth of the optical fiber cables. In this paper, anew radio-over-fiber (RoF) architecture for future 5G networks isproposed using SCM-MDM for converging data streams fromdifferent picocells. Different sets of the Hermite-Gaussian (HG)modes are introduced for the SCM-MDM system in RoF. The effectof different sets of HG modes on the RoF system performance arecompared in terms of the transverse electric fields, eye diagrams,modal analyses and bit-error rates. A total throughput of 19.5 Gb/sis achieved

High Performance Direct Torque Control of Induction Motor Drives: Problems and Improvements Nik Rumzi Nik Idris; Tole Sutikno
Proceeding of the Electrical Engineering Computer Science and Informatics Vol 4: EECSI 2017
Publisher : IAES Indonesia Section

This paper presents some of the main problems, as well as their root causes, of Direct Torque Control (DTC) 3-phase induction motor drive. The high torque ripple in DTC drive due to the hysteresis controller inevitably becomes worst with the discrete implementation of the drive system. The hysteresis controller also causes variable switching frequency that depends on operating conditions, especially the speed. The simplification used in stator flux expression for voltage vectors selection in flux control results in a poor flux regulation at low speed. To overcome these problems, techniques that have been implemented at UTM- PROTON Future Drive Laboratory (UPFDL) are presented and described. Some experimental results obtained from the previous works are also presented and discussed.

Towards Development of a Computerised System for Screening and Monitoring of Diabetic Retinopathy Hanung Adi Nugroho
Proceeding of the Electrical Engineering Computer Science and Informatics Vol 4: EECSI 2017
Publisher : IAES Indonesia Section

One of the complications of diabetes can lead to vision problems when it occurs in the retina which is known as diabetic retinopathy (DR). In practice, to diagnose and monitor DR severity, ophthalmologists observe the presence of several pathologies in colour retinal fundus images. However, this approach is tedious and time consuming, especially in the case of screening for early detection. Several techniques have been developed to achieve the final goal that is an automated DR screening system. This paper presents three kinds of approach towards the development of a computerised DR screening and monitoring system. The first approach is pathology-based methods. This approach detects and analyses several pathologies such as microaneurysms, haemorrhages, exudates and changes of retinal vessels. This approach achieves the performance results of more than 90% of accuracy, sensitivity and specificity for detection of the pathologies. The second approach is retinal structure-based methods. This approach detects optic disc, macula and foveal avascular zone (FAZ). The FAZ determination successfully achieves the accuracy of around 97%. DR severity has been proven to have strong correlation up to 0.912 with the enlargement of FAZ. The third approach is deep learning-based methods. This approach has achieved promising results with accuracy of more than 95% in screening and grading the severity of the DR. The third approach offers several advantages compared to the two previous ones in which this approach does not need to specifically detect the presence of pathologies nor the retinal structure to determine DR grade. However, this approach needs huge dataset to learn. The next development is to implement the deep learning based method into a low-cost embedded system.
