Various neuroimaging modalities have appeared to acquire brain signals for developing a brain-computer interface (BCI). In this article, we review studies on different modalities including both invasive and non-invasive techniques for the implementation of BCIs, for brain signals detection, decoding, feature extraction, and classification. We discuss their advantages, disadvantages, and implementa... View full abstract»

Dysplasia is a precancerous disease that tends to convert into carcinoma in-situ if not diagnosed and treated in time. A MEMS (Microelectromechanical System) based microgripper can mechanically diagnose the disease by measuring microscopic changes in cell size, nuclear to cytoplasmic ratio and cell membrane stiffness. The objective of this paper is to present novel MEMS based microgripper with int... View full abstract»

This paper describes the developments of Bio-MEMS using fabric as the structural components. The use of fabrics for Bio-MEMS construction significantly simplifies the conventional fabrication process. In this paper we proposed a new fabrication process for fabrics-based Bio-MEMS. In addition, to the simple and low-cost fabrication process, stamping method offers a number of advantages which is les... View full abstract»

This paper discussed the thrust characterization of the contractile water jet thruster using Ionic Polymer Metal Composite (IPMC) actuators. In this research, the effects of current input variation on the generated thrust at different nozzle size had been studied. By adjusting input power to the actuators, the optimization of the system which influenced by the nozzle opening area had been determin... View full abstract»

In this paper we propose an approach, the global path planning for multi-robot system with cellular automata. The idea is to calculate the distance from all possible robot positions to the goal. The candidate path is determined by selecting the neighboring cells with the smallest value. We solve this problem using a particular rule of cellular automata to perform the process of computation. This p... View full abstract»

Today, the development of manipulator robot technology is growing fast and giving good impact for human life. Application of the manipulator robot technology can help many human's tasks effectively. However, most publications in this field of interest are based on complex computation, by using mathematical model from the actual robot. This paper proposes a control system for manipulator robot usin... View full abstract»

The main problem on PID controller design is tuning its parameters in order to generate optimal systems performance. This paper applies Genetics Algorithms (GA) for tuning PID controller of an air heater. PID controller is used to control the output temperature of the air heater. A process model of the air heater is defined based on its open loop step response. Using this model, an offline PID par... View full abstract»

In the communications field, many methods have been introduced in order to improve the quality of signal reception. This is because various parameters can limit the quality of signal reception such as multipath fading and interference that results the signal with low signal-to-noise ratio (SNR) or no signal reception. This paper presents a multi-receiver system to improve signal reception and clas... View full abstract»

In recent years, several TCP congestion control algorithms have been proposed to increase the ability of TCP in high-speed and long distance networks. One of TCP implementations, which in MANET, opened new challenges for those algorithms to demonstrate the stability, scalability, and efficiency of the mechanism. This paper compared two TCP congestion control algorithms, namely Cubic TCP and Yeah T... View full abstract»

Task scheduling on multiprocessor systems is of a great interest since it is a computationally difficult problem due to having the possibility of failing in exploiting the true potential of the multiprocessor system as a result of inappropriate scheduling of available tasks. Static scheduling using genetic algorithms is a very popular approach as of being able to efficiently use the available mach... View full abstract»

This paper describes the usage of a Gameboy Advance (GBA) for non-gaming applications in control systems. The GBA is extended with the XPort and the XPort Robot Controller developed by Charmed Labs. Typical control problems include balancing an inverted pendulum about its unstable vertical equilibrium point. This paper also explores the capabilities of this controller, which can serve as a cheap, ... View full abstract»

Robotic applications are vast. One unique application of it is Tornado Ride in amusement parks. From mechatronics engineering education perspective, studying how such ride is designed, constructed and operated are very exciting. In this paper, the authors describe this excitement and rewarding experience when building a working model of the existing Tornado ride. The working model is useful to dem... View full abstract»

In nanotechnologies, usages of piezoelectric actuators are widely used. Since the properties of piezo-materials itself are dependent on Curie temperature and they have a reversible effect, a precise positioning using linear piezoelectric ceramic motor (LPCM) is a subject to achieve in this work. A proposed controller mode by combining sliding mode (SM) and fuzzy inference system, so called Fuzzy-S... View full abstract»

The smart assistive accident free wheel chair system is designed to give a chance for paralyzed patients to move freely within their surroundings. Like the case of any other automated wheelchair, the patient will not exert any effort to move the chair. In the proposed design, the patient will control his chair by simple verbal commands being analyzed by a built-in speech recognition system. Moreov... View full abstract»

An estimated discrete time model from analog servo motor with limited state information was obtained. The process is divided in two main parts. First, we build diagram blocks consisting DC motor and its position controller. Next, we find the whole transfer function derived from the diagram blocks. Second, we obtained sampled-data from experiment to estimate the coefficients of simplified discrete ... View full abstract»

Autonomous navigation of a mobile robot usually includes path planning and path tracking so that it can move toward the target in an unknown environment. Moreover, autonomous navigation is mainly relied on the sensors attached on the robot to obtain the information of its surrounding. In real time application, the sensor readings are not very consistent, which will mislead the mobile robot from it... View full abstract»

In this paper, we show a variant of consensus protocol for multi-agent system. Instead of using the linear consensus protocol, we use an additively perturbed linear consensus protocol. We show that our protocol solves the unconstrained control problem. We also show numerical simulation results of our protocol. View full abstract»

We propose a nonlinear control for coordinated trajectory tracking of unicycle mobile robots with collision avoidance ability. The proposed algorithm guarantees global asymptotic tracking of the reference trajectories of all individual robots. The coordinated movement is achieved by means of mutual coupling between robots. The stronger the coupling are, the better robustness in keeping the coordin... View full abstract»
