Stepper-Actuated Gripper

Stepper-Actuated GripperDescriptionThe Stepper-Actuated Gripper is a 3D-printed electromechanical gripper driven by a rack-and-pinion mechanism powered by a stepper motor.The motor’s rotational motion is converted into linear movement, allowing the gripper jaws to open and close with high precision and repeatability.It is suitable for applications requiring accurate positioning and controlled gripping force, such as robotics, automation, and maker projects.Typical ApplicationsDIY robotic armsPick-and-place systemsCNC or automation projectsLaboratory or test setups3D-printing and maker projectsRequired Parts3D-Printed Parts1× Base – structural frame and motor mount1× Pinion gear – mounted on the stepper motor shaft2× Gripper jaws with rack teeth – linear racks that open/close the gripper4× Motor spacers – printed spacers to align the stepper motor correctlyElectronics1× Stepper motor (e.g. NEMA-17)1× Stepper motor driver (e.g. A4988, DRV8825, TMC2209)1× Microcontroller (e.g. Arduino Nan
