Makeblock mBot Robot Kit (Entry-Level Coding Robot)

Description

Builds and programs a real robot from Scratch-level block coding up through Arduino, not a pre-molded plastic toy pretending at electronics. Snaps together in about 15 minutes, then runs as a line-follower, obstacle-avoider, or remote-control car while your kid actually learns what the code is doing. Open-source and expandable, 100+ compatible modules, and yes, it plugs into actual LEGO parts too.

This slot used to be LEGO Boost Creative Toolbox (17101). LEGO discontinued Boost directly, and its Amazon listings had gone third-party-marked-up and unreliable. Replaced, not dropped: full reasoning on the blog.
