One of the few robotics centers that starts at three, and it does it without screens — the little ones build in a physical "TechnoLab" before any tablet appears. The free trial is genuinely free and can be taken mid-year, so you can try a group in January rather than committing every September.
A robotics and creative tech center in the Eixample with five levels, from screen-free building for 3-year-olds in the TechnoLab up to LEGO Mindstorms competition robots for teens. Groups average 6 to 8 kids.
