Standing in the robotics aisle wondering which kit won't become another dust collector? This episode maps out the complete progression from screen-free logic toys for four-year-olds to competition-ready builds for teenagers. Chloe Miller breaks down exactly what hardware to buy at each developmental stage, which programming languages unlock which capabilities, and how to sequence purchases so each kit builds on the last. If you want to build an engineer rather than assemble a toy collection, this is your blueprint.

• The foundation stage (ages 4–7) should be entirely screen-free—directional robots like Cubetto and marble-run builders like Turing Tumble teach sequencing and debugging instincts before introducing any abstract code symbols.

• Block-based programming (ages 7–10) is where spatial logic transforms into alg ...
