How can your robot rule the world with an iron fist if it doesn't have a hand? This LG-NS robot gripper makes a great addition to a small arm or mobile base. The gripper features injection molded components and can use two standard hobby servos (not included) for open and close and wrist rotate. The clamp open to 1.3" and the wrist rotates approximately 180 degrees. It needs only a screw driver for assembly.
