A Low-Cost Robotic Hand That Mirrors Your Fingers

Marco Pucci recently shared a tutorial video about a low-cost Robotic hand that can mirror hand movements of the user. He used a new technique called Accademia di Belle Arti di Brera, a famous of state-run public academy in Italy. The hand works with the help of flex sensors that are attached with the fingers of the gloves. These fingers are kept in check by Arduino. It moves the servomotors that are connected with threads attached with the robotic hand.

The electronics of this project is indulged in creation of a glove embedded sensors and five scooters. The flex sensors used in this glove are actually small sized flexible rods that signify the extent of inclination. These are attached with the fingers of the glove that allows the finger’s movement to and fro. The bending sensors need to be connected with the Arduino with the help of resistors.

In the above figure he explains the manner in which bending sensor need to be connected. The sidebar close to the sensor must have supply from the Arduino 5V. The largest bar should be connected with the GND Arduino that passes through the resistance.
