This video is a complete evolution of LEGO-built boosters for Hot Wheels cars — from simple hand-powered mechanisms to a fully motorized, remote-controlled tracked robot.
You’ll see how LEGO Technic boosters developed step by step: increasing speed, improving reliability, and experimenting with different mechanical concepts, including an Infinity Loop test section and continuous motion setups. No talking, no rush — just pure LEGO engineering, motion, and satisfying builds. This is not a tutorial, but a curated build journey showing what’s possible with LEGO Technic and Hot Wheels when ideas evolve over time.
