Marco Pucci shared on our Facebook Page a link to the tutorial he made for a low-cost Robotic Hand able to mirror the movement of our own hand. He created it in the laboratory of new technology of Accademia di Belle Arti di Brera (“Academy of fine arts of Brera”), a state-run public academy in Milan, Italy.
The hand works with flex sensors attached to the glove’s fingers, they are analysed by an Arduino which then moves servo motors connected to threads attached to the robotic hand.
You can follow the tutorial (in italian, but you can use google translate) on this page www.marcopucci.it/arduino/ , download a zip with all the sketches, and watch a demo video below:
Gabri295 published on Instructable a tutorial for a project created during his last year of high school. It’s an artificial hand controlled by a glove with 5 flex sensors and Arduino Lilypad . The artificial hand reproduces the movements of the hand wearing the glove.
The components you need to control glove are:
• an elastic glove;
• Lilypad Arduino board (there are different versions, which usually only have 4 analog inputs, so pay attention and buy the one in the image);
• Shield to connect the Xbee module;
• 5 Flex sensors;
• 5 resistors: 47 K?;
• battery pack with 3×1.5 V batteries (Lilypad can be powered from 2.7 to 5.5 V, so 4.5 V it’s ok);
• LilyPad FTDI adapter (quite optional).The materials needed for the robotic hand are:
• a steel structure for the palm of the hand and wood for the fingers;
• Arduino UNO board;
• 5 servomotors;
• to connect the servomotors I used the Robot_Shield from FuturaElettronica, which has also a switching regulator to power the entire circuit, but you can use any shield made for that;
• Shield to connect the XBee module (I made an horrible one, but it’s economic and I needed to make it small because of the size of the Robot_Shield, you can buy even XBee shields which have also pins to connect the servomotors);
• fishing wires;
• 9 V Battery.
Below you can take a look at the schematic and then follow the steps to make one yourself!
