Robot Kits & Engine Building Sets
This category covers two product families that appeal to older builders. Robot kits are multi-model sets: a 5-in-1 kit contains the parts and instructions for five builds from one box, with RC or APP control on the supported models. Engine kits are scale mechanical models — V8, V10, V12, boxer four, jet turbine, turbo and radial propeller — assembled from brick components, with moving internals and, on selected models, APP control.
Both families suit hobby retail, gift and STEM education channels rather than the pre-school shelf. Piece counts and control options vary widely between models, so each product page states the count and the control type for that specific kit.
