What\'s Included in the Tub:

NXT intelligent brick

3 motors

5 sensors

Connection cables, including the USB cable for connecting the NXT brick to a computer

LEGO parts organized in sorting trays

Rechargeable battery pack and charger

Original storage tub and printed manual

Component Variation: Some genuine LEGO pieces vary slightly from the printed manual images, including blue connector pins instead of black and smooth tube pieces instead of ridged. These pieces are functionally identical and the set has been verified against the official inventory.

Rechargeable Battery Pack and Charger Included: This battery came from a group in which all batteries were fully charged, checked about 24 hours later, and tested to power on the NXT brick. About 20% were also load-tested by running two motors for at least 20 minutes, and none of the fully charged batteries failed. The included charger was checked and showed proper output voltage. Because this is an older rechargeable battery pack, charge time, long-term runtime, and lifespan are not guaranteed.The NXT brick can also operate using AA batteries.

No Original CDs / Free Project Ideas: The original CDs are not included, but the legacy NXT software is available online. Buyers can also find many free NXT project ideas, step-by-step building guides, and downloadable programs at \"NXTPrograms\" though most of those builds are designed for this set plus the LEGO Education Resource Set, so they may require piece substitutions or inventive solutions.
