LEGO MINDSTORMS 51515 Robot Inventor revealed

The LEGO Group has announced 51515 Robot Inventor, the latest upgrade in the LEGO MINDSTORMS robotics and coding theme.

Seven years since the last new release in the LEGO MINDSTORMS theme, the LEGO Group has announced the 51515 Robot Inventor 5-in-1 set. Using new LEGO Powered UP elements, the set takes the theme to a new level technologically, offering the same robotics and coding experience that MINDSTORMS is known for.

The 949 piece set will be available at and other retailers towards the end of the year, priced at £329.99 in the UK and $359.99 in the US.

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 learned through the process. Drag-and-drop coding teaches the process, with Python included for advanced coders.

Here are the official descriptions of the five robots included:

  • Blast – this master robot is a stoic action hero. It can fire or hammer its way through obstacles and grab items. Builders can be the ultimate commanders, programming it to scan its environment and fire darts if it senses danger. Perfect for guarding your room!
  • Charlie – this quirky sidekick helper can give out high fives, dance, play the drums, deliver small gifts, and charm friends with its smile.
  • Tricky – the sporty bot is the ultimate athlete. Code it to complete the perfect slam dunk or master a plethora of robot sports: basketball, bowling or soccer – the list goes on and on.
  • Gelo – a real life four-legged robot. Its unique mechanism means it can walk, avoid obstacles, and even perform tricks.
  • M.V.P. – The Modular Vehicle Platform gets the job done. Create and code your own remote control and build the M.V.P. into a buggy, a crane, a shooter turret or even a brick-eating truck to pick up LEGO bricks left by the other robots.

“Since the launch of LEGO MINDSTORMS over 20 years ago, we’ve been committed to helping children and adults develop STEM skills through play,” says Lena Dixen, Head of Product and Marketing Development at the LEGO Group. “We are extremely excited to introduce a new MINDSTORMS product that offers even more creative opportunities for those of all ages, and we thank our fans for continuing to show us what is possible with LEGO MINDSTORMS.
