This small gripper uses a rack and pinion design with a servo-driven pinion and opposing racks to keep the gripper paddles synchronized and parallel to each other throughout its 32 mm range of motion. It includes a special micro servo with an additional wire that gives access to its feedback potentiometer, so you can track the actual position of the gripper paddles. This product is a kit, and assembly is required.

This same gripper is included as part of the Robot Arm Kit for Romi.

What are the wires coming out of my servo?

Most standard radio control (RC) servos have three wires, each a different color. Usually, they are either black, red, and white, or they are brown, red, and orange/yellow:

  • brown or black = ground (GND, battery negative terminal)
  • red = servo power (Vservo, battery positive terminal)
  • orange, yellow, white, or blue = servo control signal line

Please check the specs for your servo to determine the proper power supply voltage, and please take care to plug the servo into your device in the proper orientation (plugging it in backwards could break the servo or your device).

Note: Some of the servos we carry also have an optional fourth green wire that is separate from the three standard ones. This wire provides access to the feedback potentiometer, allowing you to directly measure the position of the output. The servos with this extra wire have "with Position Feedback" at the ends of their product names. The picture below is an example of such a servo.
