I need some information about robotics hand. I want to know how does finger and thumb make for ROBOTIC hand.
I mean This is hard part for me, I have attached Image

1)which mechanical and electronic components are used to make thumbs and four finger ?
2) If anyone know about any link or thread please share

There are several techniques used today depending on the application of the robotics.
  • Micro motors in each joint (research projects)
  • Pulley systems using wires (high load applications)
  • Electronic muscles (high speed applications, still a lot of research going on here)
A Google search on bionic robotics well provide a lot of books and articles on the subject.

The hand in the picture looks like some sort of pulley system.

How much torque you need at each joint.
How fast joints must rotate.
Strength of available materials.
What prime movers (motors) are available to you.
Budget.
Weight of components.
What will power the hand.
Skills needed to construct parts.

I wasn't talking about motors specifically. You asked "what basic things we should know?"

As for motors and pulleys, what motors do you have available? What is their spec? Will you want increased mechanical advantage by using multi-pulley blocks? We can't make any particular recommendations until we have some more information to work from.

You also need to know your range of motion, and how strong the grip must be.
Its like asking how to make a car.
