Of the five models supplied, Charlie is a quirky little helper. According to LEGO, he can give high fives, dance, play the drums, deliver small gifts and charm friends with his smile.

Gelo is a four-legged robot. According to the manufacturer, its mechanism lets it walk, avoid obstacles and even perform tricks.

To program the robots, the set offers a drag-and-drop language inspired by Scratch, as well as Python, to help beginners in robotics.

The LEGO Group presented the set as the first addition to its MINDSTORMS range in seven years.

The set has 949 pieces and was due to go on sale in autumn 2020, priced at 359.99 euros or 359.99 dollars, according to the manufacturer.
