UGEARS STEM lab - Curvature Meter mechanical model

The UGEARS Curvimeter is a mechanical model from the STEM Lab series, supplied as a build-it-yourself kit. It is designed for measuring curved lines such as routes on maps or winding paths, where a ruler cannot give an accurate result. It can also be used to measure arched surfaces and irregular lines, which makes it handy for hiking and cycling trips, and it is equally interesting for anyone curious about how such a device works.

The kit contains 109 parts and, according to the manufacturer, takes about 1 to 2 hours to assemble. A QR code leads to further information about the mechanism, and UGEARS' own AR application lets you examine the finished model in a new way.

By building it, you can follow how the mechanism works and see the engineering behind it. The finished model measures approximately 11.5 x 10.3 x 5.7 cm, making it a good hands-on learning project for children and adults alike.
