The LEGO Technic 6x6 Volvo Articulated Hauler (42114) is the perfect set for young construction vehicle enthusiasts. With authentic details and Bluetooth-controlled Smart Hub, kids can control and operate the truck using the LEGO Technic CONTROL+ app. The app offers various control screens to drive forward, reverse, steer, change speed and gear or unload the hauler's bucket, and personalizes the dashboard with authentic cockpit controls. The set also comes with challenges, achievements, and inspirational content to help develop driving skills. The model features one large angular position motor, one XL motor, and one L motor for realistic functionality. With printed instructions included, building can start without the need for batteries, but to enjoy the full power and technical functions of the app-controlled set, six AA 1.5V batteries are required. The Volvo truck toy is roughly 7" high, 23" long and 7" wide, making it ideal for construction role play. LEGO Technic sets are known for their high standards and safety, making them beloved by both kids and adults alike.
