3-Finger Robot Arm Gripper
Project type
Robotics, Gripper
Date
September 2025
Objective: Build a 3-finger robotic gripper that can pick up a variety of objects with precision.
Design: I designed this gripper around a compact NEMA 14 stepper motor that drives a central worm gear. Each finger is articulated to wrap around objects, and the entire assembly is 3D-printable. The mechanism is robust and modular, making it easy to mount on different robot arms.
Outcome: The result is a printable, stepper-driven gripper ready for integration with our TITAN arm or your own robotics projects. There is even a short animation showing how the fingers move in sync.
GET THE MODEL: The model package will soon be ready for sharing with all the necessary detail for real build. Stay tuned !
