Abstract Renewable energy should reach its maximum usage capacity, around 20%, by 2025, as laid out the Malaysian government to achieve seventh Sustainable Development Goals (SDG): Affordable and clean energy. Many actions have been implemented support idea, including development of solar panels in large photovoltaic installation. However, installations require a wide area land, efficiency offe...

This paper aims to study a control system for a surface cleaning robot and the focus of the study is the surface cleaning robot controller design. The structural framework of the propulsion control system of the surface robot is designed based on the principle of PWM speed control. The function of each module in the control system is divided and described in detail. ...

By using the power jack cable, arduino microcontroller has been programmed so that the execution of the program may takes place. Various kinds of arduino board are present in the market. In this paper, Arduino UNO ATMEGA-328 microcontroller is described in a detailed manner. Arduino software is installed in the com...

This article took the trevally crescent-shaped caudal fin mode fishes as bionic object, based on the biological observation and bionic research, established the fish swimming model of trevally crescentshaped caudal fin mode, and designed the three degrees of freedom, tailtail fins pectoral fin, robotic fish. It detailed focuses on the fish propulsion theory and robotic fish overall design, incl...

A new type of intelligent hanger was designed based on single chip and Pro-E software. 3D entity model of actuator and cover curtain mechanism are established by Pro-E. Wings structure of hanger mechanical part was adopted screw rod and motor combination of the lifting mechanism can make the wings outspread and fold, unique cover curtain structure was adopted. Cover curtain rolls up and down th...

In this article, we looked at how to go about creating a CNC pen or drawing machine of your own. Inkscape, which translates graphics and text into g- code format, was utilized as the controller for project, with microcontroller serving interface between computer language machine. The g-code transmits series x, y, z coordinates motors; servo motor controls pen's movement in response Z coordinate...

Abstract: This paper presents a characteristics analysis and performance comparison of high-speed two-phase 4/2 and hybrid single-phase 4/4 switched reluctance motors (SRMs). Although the motors are advantageous as high-speed drives, both conventional structures have high torque ripple as a result of the presence of the torque dead zone. In this paper, solutions to the torque dead zone problem ...

The equation-free framework for multiscale computing is built around the central idea of a coarse time-stepper, which is an approximate time integrator for the unavailable macroscopic model when only a microscopic simulator is given. In this paper, we study the numerical properties of the coarse time-stepper when a lattice Boltzmann model for one-dimensional diffusion is used as the microscopic...
