Driver’s mental workload is affecting the driver’s performance while driving. A high mental workload task proved that the driver’s performance level decrease. The decreasing of driver’s performance lead to driver carelessness that causes a road accident. Thus, the way to estimate and monitor the driver’s mental workload has to be developed. The pur...

The mechanical transfer lift is a device used to assist caretakers when transferring patients from one position to another. While using a manual transfer method, they need to extract a large amount of energy to transfer the patient; resulting in back pain and stress. From the engineering design process, the main objective of this research is to com...

It is known that unnecessary increase of driver’s mental workload may be a cause of road traffic crashes. In the recent decades, mental workload’s level detection has been one of the major interesting research subjects in today’s society. This paper discussed the relationship between driver’s performance and mental workload level. The results revea...

Distracted driving has emerged as a factor of road accidents. Usage of cellular phones or car navigation systems has aggravated the problem. Therefore, the detection increase of drivers’ mental workload has been a vital issue for establishing safety support systems. Studies on the estimation of driver’s mental workload have been performed using a v...

Stochastic Resonance (SR) is a significant concern for design of robotic tactile sensors because of its considerable enhancement of sensitivity of human tactile sensation. In the last few decades, researchers have found that noise previously considered detrimental in fact provides the benefit of SR phenomena. However, there are no experimental resu...

This paper presents experimental results of object handling motions to evaluate tactile slippage sensation in a multi fingered robot arm with optical three-axis tactile sensors installed on its two hands. The optical three-axis tactile sensor is a type of tactile sensor capable of defining normal and shear forces simultaneously. Shear force distrib...

ntelligent Speed Adaptation (ISA) is a system that constantly monitors vehicle speed, local speed limit on a road and implements an action such as giving warning or discourages the drivers when the vehicle is detected to be exceeding the speed limit. A GPS connected to digital speed map allows Intelligent Speed Adaptation technology to continuously...

Autonomous Unmanned Aerial Vehicle (UAV) in the form of multi-rotor system is having a great potential in various applications such as disaster management (as first response system) and surveillance. It is known that conventional helicopter system, capable of hovering, is practical and reliable as many applications have confirmed its capabilities....

The velvet hand illusion (VHI) is an innovative tactile illusion that enables a human to perceive a velvety sensation by gently rubbing the hands on both sides of wire mesh string through a frame. In order to enhance tactile displays presentation ability, VHI's mechanism is applied through a series of psychophysical experiments. In this paper, we h...

This paper presents development of new haptic display capable of stimulating the muscles and tendons of the forearms as well as the tactile receptors in the fingers as a new approach for virtual reality device. Investigation of simultaneous presentation of both tactile and force effects are conducted and presented in this paper. The haptic display...

This paper describes sum of absolute differences (SAD) algorithm to calculate optical flow function. This algorithm is used for optical flow estimation between two frames of colored photo image. The algorithm is combined with parallel processing, modern general purpose Compute Unified Device Architecture (CUDA) Graphic Processing Unit (GPU) to redu...

Intelligent Speed Adaptation (ISA) is a system which informs, warns and discourages the driver to exceed the statutory local speed limit. The in-vehicle speed limit is set automatically as a function of speed limit indicated on the road. GPS allied to digital speed limit maps allows ISA technology to continuously update the vehicle speed limit to t...

In a population of aging with low birth rate, many elderly become bedridden because of their suffering from injuries or diseases that require a long period to heal and rehab. We developed the lowest cost of production while provides the highest performance and reliable prototype. The selective 27 parts were identified and used in this project inclu...

This paper presents a study on control architecture improvement of a MM3A microrobotic system (MM3A) in terms of high precision capability using a hybrid control strategy viz. PD control scheme integrated with intelligent Active Force Control (AFC) and Fuzzy Logic (FL). The dynamic model of the MM3A is derived using Recursive Newton-Euler method. T...

Distracted driving has emerged as a factor of road accidents. Hence, the detection increase of drivers' cognitive workload has been a vital issue for establishing safety support systems. Studies on the estimation of driver's mental workload have been performed using various devices. However, an applicable and a sensitive device is still vague. One...

Dynamic Ankle Foot Orthosis (DAFO) is a revolutionary of the Ankle Foot Orthosis, which is an equipment used to control the motion and position of ankles. It is designed to correct deformities for patients who require treatment of disorders related to muscles and nerves functional failure. Unfortunately, the current designs of DAFO are limited only...

This paper demonstrates, theoretically and experimentally, the feasibility of utilizing Shape Memory Alloy (SMA) as an actuator in controlling the flexural vibrations of a flexible cantilevered beam. The shape memory alloy used in this study is merely a straight wire which is made of nickel titanium alloy called Nitinol. Acting as tendons, these SM...
