The STEM Mechanics Master set is the ultimate combination of the main subjects of Simple Machines and Physics, including Levels, Pulleys, Gears, Linkages, Newton’s Laws, Energy conversion, Solar Power and Structures. The patented geometry of ENGINO® components allows connectivity to all directions of the 3D space, enabling users to easily create technical models. This unique set enhances creativity and imagination while also teaching a variety of STEM principles. A geared 3V motor with a large solar panel is included for animating the ENGINO® builds, converting solar energy to electricity. The set comes with a library of high-precision gears, pulleys and axles for changing speed, force and direction of motion. From this set, besides open projects, students can find digital instructions for 100 working models and amazing animated contraptions such as cars, cranes, bridges! This kit can be used to prepare for the STEM Design Challenge Competition.
