SCARAPAINTER 2026

The SCARAPAINTER is a project I built to turn complex math into something visual. It’s a parallel SCARA arm that uses inverse kinematics to calculate exactly how to reach different points in space. I used stepper motors to move the arms and controlled everything with G-code derived from the inverse kinematics formulas I worked out. I even added a pen at the end-effector to map out the points, which makes it really easy to visualize how the math translates into physical motion. It was a cool way to see my engineering calculations actually come to life.
