Robotic servo grippers compatible with Arduino, Raspberry, PICAXE.....

I have designed and manufactured these grippers with a 3D printer. 

The main features of these robotic grippers are :

1. The grippers are robust and light.
2. The grippers allow the manipulation of large objects, with an size of 77mm.
3. The grippers allow two degrees of freedom, the opening and closing of jaws, and the rotation of the gripper.
4. The grippers uses two RC standard servo motors. One servo rotates between 0 to 180 degrees and the other servo is a 360 degrees servo.
5. The gripper can be connected directly to all Arduino, Raspberry Pi boards and PICAXE boards or any other board.. The boards don't need shields. We can use the standard pins of Arduino.
6. The microswitch of the gripper designates the closing of the jaws.
