    This research is for facilitate the healthcare worker to approach patient that located in distant areas via internet. Also, patient need not to get to the city to see a doctor. Hence, this research will reduce time and cost of traveling. This research is to create tele-control robot arm, use in the operating room, which is controlled by joystick from anywhere. It is separated into 2 parts that is hardware part to design and print 3D robot arm and joystick and software part, which is code to control robot arm also send controlling data via internet. Furthermore, this project will send real-time video from robot arm to controller side. The data is sent between robot arm and joystick by nodeMCU or in this project use two ESP32, one will receive data from joystick and send the data to another for control robot arm. In the section of sending real-time video, this project use Raspberry pi as a device for sending.

    This paper presents a two-wheeled robot control that can balance upright on its own by controlling the angular speed of the motor to keep the robot upright using measured data from the gyroscope sensor. The aim of this study is to demonstrate the design of fractional-order PID controller (FOPID) that has more controllability and the ability to adjust outperform traditional PID controller. The design of optimal FOPID controller based on integer-order PID parameters are explained and validated its performance compared with the traditional PID controller using Matlab simulation. As well as the real system experiment is implemented on Raspberry Pi using IIR filters cascaded second-order section form II. The study revealed the appropriate concept of implementation of FOPID on the real system.

    This research proposes the smart way to solve the common problem of the conventional door-locking system. The important problems of the ordinary door-locking systems are key lost, forgetting to lock the system and cannot check the lock status from remote. To solve these problems, we proposed a method to lock-unlock the system which utilizes the web application and passcode alongside the usual method of using the ordinary keys. The proposed system can remotely lock, remotely unlock, remotely check door state, remotely check door locking state, send the email to the owner in case of someone knocking on the door and generate the temporary passcode to use in specific date and time.
