This app-controlled tracked vehicle has two designs top and bottom with tank-like bogey suspension.
Lego's Technic sets are known for recreating real-life vehicles down to the last detail — but sometimes you just want to have fun. The App-Controlled Transformation Vehicle uses tank treads and a battery-powered motor to climb obstacles and flip over when it hits a wall, transforming from a tracked exploration vehicle to a sleek racing body. Bogey suspension, like the kind used on real tracked vehicles, allows it to climb obstacles, and the app lets users control the vehicle remotely and switches screens when the vehicle flips.
