#51515 LEGO MINDSTORMS Robot Inventor is aimed at older builders.

In the past 3 years, The LEGO Group has significantly re-structured Education-focused products, with the “BricQ Motion” sets offering brick-based physics instruction at a modest price point, and the “Spike” sets offering kids an introduction to programming and robotics (but at a higher price point). (At this time there are no Technic sets for ages 6+, and only five sets labeled for ages 7+.) Spike Essential vs. Using studded connections instead of Technic connections is an important simplification for younger kids who have limited experience with Technic, especially given that this set is targeted at ages 6+. The biggest difference is the shift from using almost exclusively Technic Beams/Pins to create structures in the sets aimed at older kids to the use of mostly System Bricks (Stud and Tube connections) in this set. To be clear, this is a much simpler set for younger kids, as compared with #45678 Spike Prime or the consumer-facing #51515 LEGO Mindstorms Robot Inventor sets. #45345 Spike Essential – Outer shipping box and storage tote.
