RANCANG BANGUN DUA LENGAN ROBOT BERJARI MENGGUNAKAN SENSOR FLEX SEBAGAI SENSOR GERAK PADA JARI TANGAN BERBASIS ARDUINO

Two-fingered arm robot is already manufactured and used in the automotive industry and electronics. The design of the two-fingered arm robot is divided into two parts, the controller on a human arm (Transmitter) and fingered arm robot (Receiver). Two-fingered arm robot uses an Arduino Mega 2560 on the controller arm (Transmitter) and fingered arm robot (Receiver). Media data transmission wireless at the transmitter and receiver using Bluetooth HC-05. Finger hand robot is controlled by Spectra Flex Sensor 4.5 inch Symbols Series SEN 08 606 by utilizing the resistance of Flex Sensor through degrees of curvature. Flex Sensor is a curvature sensor with a flexible physical which can follow the movement of a human finger. Range of flex sensor resistance from 10 KΩ until 35 KΩ. Changes resistance of Flex Sensor value is directly proportional to the degree of curvature given on the physical Flex Sensor. The value of curvature degree of Flex Sensor range from 0o until 180o. Flex Sensor as controller-fingered arm robot has a percentage (%) of measurement error from 6% until 11.4%. The resistance value from Flex Sensor will control the servo motor HS-81 which will move the fingers of the robot hand. Required balancing between mechanical and electronic design to produce the maximum performance of the two-fingered arm robot
