Why we recommend it
A four-pack of the same MG996R workhorse, which lines up neatly with a 4-DOF arm (base, shoulder, elbow, gripper) or leaves you a spare on a 3-DOF build. The metal gear train and digital control give you the torque and holding power an arm needs at the lower joints. As with any MG996R, run the servo power from its own 5–6V rail rather than the Arduino’s 5V pin — they pull far more current under load than a board can supply.
