LEGO Mindstorms EV3

EV3 is the most famous generation of LEGO Mindstorms, and for many teens, it’s their first “real robot.” This kit centers on the EV3 programmable brick, which connects to motors and sensors to create everything from line-followers to walking bots. Designed for ages 10+ and used heavily in classrooms and competitions, it introduced a visual programming environment as well as options for text-based coding. Parents appreciate the depth: entire year-long courses have been built around EV3, and there’s no shortage of tutorials online. Although officially retired, it remains ideal for middle and high schoolers who want to dig into robotics with a familiar LEGO feel. Replacement parts and official app support can be patchy now, but community-maintained tools help extend its life. Pro tip: start with a simple robot from a well-reviewed book or site, then gradually modify it rather than jumping straight into totally original designs.
