In this world there are many people who are physically disabled. In our daily life our hands play an important role in doing basic activities but what about the unfortunate people who are not able to use their hands or don’t have hands, Re-Arm is a low cost artificial hand that will help the disabled to do their daily activities with ease. It is difficult for such physically disabled people to live a normal life, without depending on others. For every activity, they need a help from someone, they cannot do it by themselves. For paralyzed people, some of their paralyzed organs are of no use and need time to time help and exercise. Re-Arm provides with a physical arm structure and an android mobile application which will help to control the artificial hand. The user will have to just speak the movement and the app will control arm as per it. User can also make the artificial hand respond in the same way as his /her other hand by just selecting the mirror mode the default will be simple m
step1 first u got to make a structure of ur hand. we have used the pvc (plastic ) pipe to make the hand hollow structure. for the wrist and palm part we have used metal sheets that can be easily bend. the major connecting part is the mechanics. we used the strips of mechanics kit (game) to connect all the parts.
step2 once ur hand structure is ready u first check each and every bend of the structure, it should move as our normal hand. after thestructure i working good, u need trhe following components
1. arduino uno board
2. flex sensors
3. servo motors
4. Bluetooth chip
5. 6V rechargable batteries 6. jumper wires
8. 1ohm resistor.
step 3 after u have all the components attach the servos on the joints, to perorm the movement. take a white glove that is long till our biceps, attach the flex sensors on the joint. now use the arduino board to connect the flex sensors and servo. connect the servos to the external batteries. and then upload the code to arduino.
