In this study, author introduces gait of a serpentine robot with linear expansion mechanism where the robot varies its length using joints with three degrees of freedom. This gait is important for robots designed to explore ruins of disasters where the working spaces are very tight. For maximum flexibility of

The purpose of this project system is to manufacture to measure and monitor the development of temperature in the refrigerator using temperature sensors, where the measurements are distributed via TCP/IP. The temperature measurement tool is expected to determine the increase and decrease in temperature in the refrigerator. The system building

The purpose of this study is to monitor the water levels at Katulampa dam. This research uses Arduino as the main module with microcontroller ATmega 328, PING ultrasonic sensor as a water height detector, and GSM module for communication media of water height data with short message (SMS) format. The

The purpose of this study is to apply color sensor TCS3200 as a detector for checking fruit ripeness by color. The device is expected to automate the sorting of maturity stage of post-harvest fruits. The system which serves as a driver or a fruit sorter is controlled by a motor

Brushless DC is well-known in both the industry and Tamiya-fan, as a type of motor that is lightweight and efficient in design, yet requires electronic commutation. This article discusses comprehensively the selection of the right type of mosfet BLDC motor specifications. This is very useful during implementation. For beginners, this

This study designs a system which increases the punctuality and reduces errors in identifying goods that will be delivered in a distribution company. This automatic separator is designed to ease the separation of goods based on destination city. It substitutes the system from manual to Automatic using RFID technology and

TV broadcast system are now starting to migrate from analogue broadcasting system to a digital one. Indonesia is planning to fully migrate in the year 2015 2018. For the government as a regulator, the application of digital broadcast system will improve the efficiency of the use of the frequency

Data mining is used to obtain patterns that can represent information or knowledge from a big number of data. Eventhough the main application is to extract information from business transactions data, a lot of researchers also use it for other types of data. The process results in various forms of
