3 Fingers Robot Arm Gripper Model

At ZEED ROBOTICS, we’re constantly exploring practical, efficient designs for real-world robotic applications. One of our latest developments is a 3D-modeled 3-finger robot arm gripper—a compact, reliable solution for gripping objects with control and adaptability.

Smart, Centralized Actuation

The gripper is driven by a single stepper motor, which powers all three fingers through a central mechanical linkage system. This design ensures synchronized motion, precise control, and minimal wiring or programming complexity. It’s a simple yet powerful setup that makes the gripper both reliable and scalable.

Curved Fingers with Passive Flexibility

Each finger features a curved geometry, allowing it to naturally wrap around objects. This curve provides passive spring-like behavior, adding tolerance for varying shapes without extra sensors. At the tips, rubber pads are added for extra grip—ideal for smooth or fragile surfaces.

Built for Function and Flexibility

Our goal with this project was to create a gripper that balances mechanical simplicity with real-world effectiveness. Whether used in pick-and-place robots, educational platforms, or custom automation setups, this gripper is designed to be modular, 3D-printable, and easy to integrate.
