Robotic hand

[yifei87]

hey guys,

          i am on my project building a 5 fingers robotic hand.
         
          what is suitable for the hand's shape? the length of each fingers need to calculated and how?
         
          what kind of motors should be used to make a grip fast enough to catch ball thrown to it?

          And for the hand structure, what kind of matrial that i should use?
          Thank you for help.

you are basically asking us to do your entire project for you.

Please do some research on the internet before asking such a general question.

start broad, there are many different mechanical hand designs that have already been accomplished. You may want to begin by researching those different hand types.
