LEGO MINDSTORMS brique intelligente EV3, robot, , MINDSTORMS Education EV3, gris

Thought it came with a charging cord and charger pack.

Lego Mindstorms is a world-wide phenomenon. The heart of the system is the Intelligent Brick, a sophisticated computer that includes analog-to-digital converters for robotic sensors and outputs for motor controllers. It also has an LED screen, input keys, and built-in Bluetooth and Wi-Fi. The most modern version, the EV3, can even interact with other EV3s to enable cooperative robotics. I already had an EV2 system, so I decided to upgrade starting with the EV3 brick itself. It's a wise choice. My EV2 sensors and motors work perfectly with the new brick, and the Mindstorms programming system offers the same block-based interface used in previous versions. Note that you don't have to buy the brick separately if you already have an EV3 kit. Mindstorms is a learning experience that can help both adults and kids learn about mechanical design, programming, planning, collaboration, and robotics. The only downside is that Mindstorms is addictive!

Purchased for my friend in China. She loves this and it is really cheaper than it in China.
