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.
