## Description

- description: A fully open-source, 3D-printed robotic system is developed for automated
    pH measurements. The robot integrates a stepper motor – driven lead screw and
    an analog pH sensor to enable precise vertical positioning of the probe. A terminal-based
    control program allows automated motion and data acquisition, with safety features
    preventing overextension. Evaluation with standard buffer solutions (pH 4.0 and
    7.0) demonstrates accurate and reproducible measurements. This modular, low-cost
    platform facilitates scalable and reproducible data generation for materials research.
