Which is why the best feature of Mabot, a STEM-learning robot-building kit featured on OGadget, might be its least flashy: it’s compatible with the Lego bricks your kid most likely owns (and loves) already.

It’s the first modular robot kit that allows nearly endless combinations of robot builds that is simple to use, educational, as well as fun for the whole family.

One thing is certain: the Mabot is a hit with my kids (and me), particularly my coding-minded 10-year-old. She’s already asking if we can get an additional set so she can have more parts to build bigger models. I really like the way that the various modules snap together easily, and the programming app gives it a lot of possibilities.

The 'Mabot' robot toy is an example of how the product market is evolving to meet these stringent demands with a design that can be used by boys or girls and that works with other devices through the accompanying app.

In all, the simple design of the Bell Robot Mabot is just about right for teaching kids how to consider more than just "this fits on that" complexities in building with their imagination. The Mabot has a really clever system of modular components and the flexibility of design to allow a lot of creativity during that learning. My kids had a blast with it.
