LEGO BOOST is a robotics LEGO set aimed at children aged 7 years and up.
The Move Hub smart brick communicates with a touchscreen tablet (Android, iPad or Windows 10 - see compatibility list) which needs to be purchased separately. Programming the device occurs in a block-based programming system (similar to scratch) that is touch-based, and each model has different programming blocks relevant to their capabilities. Progressively higher-level programming areas are unlocked as the easier ones are completed. In addition to the two motors/rotation sensors built into the hub, there is an external motor/rotation sensor, and a light/colour sensor that connect to the hub through cables.
