Grippers & Claws
The gripper is what turns an arm into a useful machine. Building one from scratch is fiddly, so a ready-made metal claw — driven by a single servo — is often the smart shortcut. These end effectors bolt onto the wrist and convert one servo’s rotation into a parallel pinch. Pick one with a servo included to get moving fast, or without if you already have a spare high-torque servo.
