Robot Gripper

2 DOF Robot Gripper is a compact mechanical end-effector designed for small robotic arms, mobile robots, and experimental automation platforms. Dual-servo architecture enables independent control of gripping and rotational movement, creating flexible manipulation capability in lightweight robotic builds. A 0–54 mm adjustable clamping span allows handling of various small objects, while the lightweight structure keeps payload impact minimal. The servo-compatible mounting slot supports common hobby servos including DSS-P05 Standard Servo and DF Metal Geared 15Kg Standard Servo, making the robotic gripper mechanism easy to integrate into custom robotic projects and research prototypes.

Dual‑Servo 2‑DOF Motion Architecture

A two‑degree‑of‑freedom structure enables precise manipulation in robotics applications. One servo drives the jaw opening and closing action, enabling stable gripping of small objects, while the second servo controls rotational movement of the end‑effector. This mechanical separation of functions allows robotic arms or mobile platforms to perform both positioning and grasping tasks simultaneously, making the servo‑driven gripper mechanism suitable for pick‑and‑place experiments, robotic manipulation demonstrations, and prototype automation systems.

Wide Servo Compatibility

A standardized servo mounting slot supports a broad range of hobby and robotics servos, simplifying installation and replacement. Compatibility with widely used servo models allows flexible torque selection depending on the robotic application. Example supported models include DSS‑P05 Standard Servo and DF Metal Geared 15Kg Standard Servo, enabling the gripping module to be adapted for lightweight research robots, educational robotic arms, or higher‑torque experimental manipulators.

Lightweight Structure with Practical Grip Range

A compact mechanical frame weighing about 45 g minimizes load impact on robotic arms and small mobile robots. The adjustable clamping range from 0 to 54 mm (0–2.13") supports grasping of various small objects including blocks, sensors, and lightweight tools. Balanced size and grip span make the robotic claw module practical for laboratory experiments, prototype automation rigs, and educational robotics systems where both payload efficiency and reliable grasping are important.
