This robotic hand is constructed using four servo motors and four potentiometers as position sensors. the position sensors are attached to a wearable glove which is used to control the robotic arm interactively. The robotic hand depicts the movements of a human hand wearing the sensor glove. The control pins of the servo motor are connected to PIN no. 9, 10, 11, 12 respectively; and the pisition sensors are connected to the analog PINs 0, 1, 2, 3. The analog values are mapped from (0,1023) to (0,180) using the map() function in Arduino and are constrained within these limits using the constrain() function. These calibrated values are written to the servo motors pins using Servo.write() function.
