“51515 Robot Inventor offers five different designs for fans to build, which can them be programmed via the MINDSTORMS Robot Inventor app. Beyond the five models with instructions, there are coding challenges to complete that will require users to apply the skills they have... More learned through the process. Drag-and-drop coding teaches the process, with Python included for advanced coders.”

Eurobricks

“If you are a novice robot builder, I would definitely recommend getting this set. If you want to make more advanced robots with bigger programs and more options, I'd recommend getting the EV3. A lot of (third party) stuff is available for the EV3, which allow for a ton of... More options.”

The Brothers Brick

“The set may not be perfect, and may not be everything LEGO Mindstorms fans hoped it would be. But it is fun, and users new to the platform are sure to enjoy it, while old hands can find some silver linings along with some new things to experience.”

About Mindstorms

LEGO Mindstorms is a hardware and software system desigend for the development of programmable robots made out of TECHNIC bricks. The original LEGO Mindstorms Robotics Invention System was born out of a collaboration between MIT and the LEGO group's eductaional division. Since the release, there have been a number of generations of the Mindstorms platform: the original Robotics Invention System, NXT, NXT 2.0, and EV3 and weth each platform release, the motor and sensor capabilities have greatly expanded. Mindstorms are also sold and used as an educational tool and called Mindstorms for schools or Mindstorms Education.

Enter the amazing physical and digital world of programmable, remote-control robots and intelligent creations. With LEGO® MINDSTORMS® Robot Inventor (51515), young robot fans build 5 unique, motorized robots and vehicles using the free LEGO MINDSTORMS Robot Inventor App. Then they bring them to life, one at a time, using the drag-and-drop coding environment based on Scratch and complete fun activities and challenging missions (visit LEGO.com/devicecheck for a list of compatible devices). And with almost 1,000 pieces, kids will love to come up with their own tech toy creations and share them with other robot fans on LEGO Life.

Level up the play experience
From the intelligent Hub with its 5x5 LED screen, 6-axis gyro and speaker, to powerful motors and accurate sensors, the latest evolution of LEGO MINDSTORMS coding robots for kids is the perfect way to help youngsters express and develop their creativity, while gaining essential 21st century STEM skills.
