JonHylands, who is on this forum, has created a couple of grippers before. Check them out -

Right, tell us some things about your arm.
How big is it?
What will it be picking up?
How is it currently actuated?
What facilities do you have access to to manufacture an end effector?
What is you goal objective for the arm?

With these answers we might be able to point you in a more suitable direction.
