This set contains a wide range of elements and is an ideal supplement to the EV3 Core Set. It has been designed to allow students to take their experience of robotics to the next level. There are plenty of special elements here, such as different gears, a large turntable, robot personalization parts and unique structural elements. These are joined by many extra standard elements like beams, axles and connectors. This set both helps students build larger and more complex models while at the same time providing extra or replacement elements. The set is optimized for use in the classroom and after school programs or robotics competitions. It will be delivered in a sturdy and stackable plastic storage bin. You can download additional building instructions and programs for several models from LEGOeducation.com/MINDSTORMS.
