Collection: Grippers & Claws

Overview

A robot arm gripper is the end effector that determines what your robot can pick up, move, and manipulate. Our gripper and claw collection includes servo-driven mechanical claws and pneumatic-style suction cup attachments — all with metal construction and standard servo mounting compatible with any robot arm in our catalog.

Types of Robot Arm Grippers

Mechanical claws use a servo motor to open and close two opposing fingers — ideal for picking cylindrical objects, boxes, or anything with a graspable edge. Suction cup grippers use a servo-actuated pump to create negative pressure — ideal for flat surfaces like PCBs, glass, or sheet metal. Choosing between them depends entirely on your workpiece geometry. For educational and hobby use, the mechanical claw is more versatile. For pick-and-place automation, suction cup grippers are faster.

Mounting to Your Robot Arm

• Standard M3 pattern: Compatible with all arms in our catalog and most third-party robot arm frames
• Single servo signal wire: Connect directly to any spare PWM pin on Arduino or servo driver board
• No additional driver needed: Standard 5V PWM control, same as any other joint
• Modular design: Swap between claw and suction cup without re-wiring the arm
