Why we recommend it
A heavier-duty end effector with wave-edge jaws that grip irregular objects securely, rated to about 1 lb (0.45 kg) and opening up to 9 inches. It ships without a servo, so you supply a high-torque metal-gear servo (MG996R class or stronger) — handy if you already have spares. The wide opening and metal build make it a good upgrade over plastic claws when you want to pick up real objects, not just demo blocks.
