The UGEARS STEM wooden mechanical puzzle curvimeter (opisometer) is a functional educational model that lets you measure irregular curves precisely — from coastlines on a map to tracks for toys. The mechanical principle with a planetary and cycloidal gear train draws every curious builder into the world of physics and engineering.
Made from high-quality plywood, the kit offers 109 precisely cut parts, low difficulty, and a build time of 1–2 hours. The model is STEM.org certified, and you can easily expand it with interactive elements thanks to augmented reality in the UGEARS app (QR code). Great for home learning, clubs, and school projects — designed and made in Ukraine.
