  • Brass sleeves in joints
  • Can pick up heavy objects
  • Spring-loaded clutch
  • 2:1 gearing
  • Light weight servo motor


The brass sleeves in joints make them rigid and hence are less likely to come loose. The weight of objects that the claw can pick up depends on the servo motor used.

The spring-loaded clutch of the claw helps protect servo gear train while providing spring tension for gripping objects while the 2:1 gearing increases gripping torque while utilizing the full 180° travel of the servo.

The mounting plate on the bottom accepts standard spacing found on servo mounts.

The 20 gram DGServo S05NF STD servo motor, included with this claw, has metal gears, and a stall torque of 2.8kg*cm at 4.8V and 3.2kg*cm at 6V. It also has a speed of 0.2sec/60° at 4.8V and 0.18sec/60° at 6V

If your gripper does not close properly then you may need to take the pinion gear back
out and rotate it by one tooth. Check out the Assembly instructions on how to do this properly.
