COMPACT HUMANOID ARM FOR INDUSTRIAL USES

Science grows with the growth in revolution of different inventions and discovery in various fields but often these inventions and discovery tends to ignore the need and the development for the handicapped person .What if they would be able to do their day to day activities as fast as the normal person. If the limitations of these people are removed, we might be able to have some more innovative brains working with us and for this HUAMANOID ARM could be the first step towards its initiation. By using humanoid arm a handicapped person would be able to do almost everything which a normal person does with  hand and they would not have to be dependent on anybody

THE PALM
The base of the palm of the humanoid arm is made up of medium wooden sheet. The base has a length of approx 11cm. Five chain pieces (used in bicycle) are used for making the fingers of the palmSo that the movement of the fingers become as smooth as possible now three small pieces of springs are attached to each finger so as it can act as a powerful joint of the finger. Now each finger is connected to their respective servomotor with the help of a strong plastic string through the medium of thin and strong plastic pipe so that the string do not move trough its firm and assigned position                
CHAIN PIECES (Fingers of the arm)

Five different size chain pieces were cut from a long cycle chain used over the gear. The cycle chain was used due its ability of smooth movement in the required position just like real fingers

SPRINGS

Small spring pieces are used as the joint for the finger each finger consists of three small springs  one spring at the bottom most of the finger, the middle spring is attached above approximately 2.5 cm above the bottom spring  and the topmost spring is above 1 cm of the middle one also each spring is almost 2cm  to 2.5 cm in size.
