This is my school project for the 5th year of high school (I'm Italian, we have 5 years of high school).
It consists in an artificial hand controlled by a glove with flex sensors. The artificial hand reproduces the movements of the hand with the control glove, wirelessly. The hand and the glove works both with Arduino.
I just wanted to share my work for everyone interested :)
This guide is still in development, sorry if some parts are not clear, I'll put some 3D images in future.
I'm sharing something about my project on my facebook page: https://www.facebook.com/Gabry295
Step 1: Materials needed
I bought almost everything from https://www.sparkfun.com/, they have fair prices (I don't mean to advertise!)
Total cost: ABOUT 160$
The materials needed for the 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);
- XBee module;
- Shield to connect the Xbee module;
- 5 Flex sensors;
- 5 resistors: 47 KΩ;
- battery pack with 3x1.5 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;
- XBee module;
- 5 servomotors;
- a servomotor shield for Arduino UNO (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 controlling servomotors);
- Shield to connect the XBee module (I made an horrible one, but it's economic and I needed to make one small because of the size of the Robot_Shield);
- fishing wires;
- fihing sinkers (to secure the fishing wire);
- 9 V Battery.
- angle grinder (mainly to cut wood and steel);
- axial grinder;
- welding machine (with electrodes);
- soldering station and solder;
- electrician's scissors;
- heat shrink tubing.
