Abstract

The research investigated the automatic control system implemented with the 5 DOF (Degree of Freedom) arm robot control system using the closed-loop control method with the MPU 6050 sensor, which integrated the rotation of the MG995 motor servo as a feedback function. The control of this robot used android–based application, in which the app sends data of the rotate angle for each servo motor rotated to a certain angle. The HC – 05 Bluetooth received the data and the Arduino UNO R3 microcontroller processed them. The microcontroller managed every rotation of each servo motor that integrated with an MPU6050 sensor with serial monitor communication to display the rotation of each servo motor. The test results obtained by the standard deviation value showed how large the sample diversity was. The result of this study showed a standard deviation correlation with the number of sample diversity. The higher the standard deviation value, the more sample data spread (data diverse or varies). Otherwise, the smaller the standard deviation value, the more homogenous the sample data. If the standard deviation equals zero, it indicates that the sample has identical data. The highest standard deviation value from servo motor 1 is 5.20, servo motor 2 and 3 are 1.00, servo motor 4 is 2.89, and servo motor 5 is 2.9

Abstract

In everyday life, particularly in hospitals, people typically use cloth or tissue to dry our hands. It seems less practical, effective and hygienic. In addition, some restaurants still use cloth or tissue as well. To overcome this problem, several hospitals and restaurants have provided hand dryers. It can dry hands but cannot eliminate germs or bacteria. It is necessary to create a hand dryer equipped with a sterilizer. This work, therefore, created a hand dryer that can simultaneously dry and sterilize hands that worked automatically using the ATMega8 microcontroller. The tool was designed by using an infrared sensor to detect hands, and an ATMEGA8 microcontroller to read and process the sensors to activate UV and heating. The results found that the tool equipped with UV and heating can dry hands while eliminating bacteria and germs.

Abstract

Calibration is required for various kinds of tools from kitchen tools such as stirrers or mixers to medical tools such as temperature calibration, ECG, blood pressure, and other instrumentation tools to be according to the required standards. In medical devices, a digital tachometer has been used as a calibration support device to measure the speed of objects that rotate in RPM on the centrifuge. Some medical devices are calibrated in km/hour, for example, the ergo cycle and treadmill. Two different devices or a conversion from RPM to km/hour are required. The research aimed to design a measurement device that performed calibration of devices with different units, namely tachometer that can be used to measure speed in RPM and km/hr. Based on the research objective, a tool was made to measure the motor's rotational speed using the E18-D80NK sensor, microcontroller, and LCD without touching the object being measured.

Abstract

Body health is the most important thing for human life. The heart is one of the organs of the body that is very important for humans. The heart functions to regulate the circulation of oxygen-rich blood and to carry leftover food in the body. Heart rate illustrates how hard the heart works. The heart rate needs to be monitored to find out the patient's condition. BPM measurement and temperature is an activity of measuring heart rate and body temperature. The patient’s body temperature affects the patient's rapid heart to pump blood throughout the body.  The study aims to design a heart rate and body temperature measuring device using an infrared LED as a transmitter and a photodiode as a receiver, an LM35 as the temperature sensor, and an LCD to display the final output. This tool uses an ATMega8 microcontroller as the controlling system.  The device was completed with data storage and temperature indicators.  The result of the test on the device showed that the device performed very well in measuring the heart rate and body temperature of adult patients aged 20 until 40 years old.
