Combined, Sphero and LittleBits have sold more than $500 million in robots and electronics. They’ve reached over six million students globally. And with this acquisition, Sphero now has over 140 patents in robotics, electronics, software and IoT.

This isn’t the first time Sphero has branched out beyond robotics. Last year, it acquired Specdrums, and it went on to produce an updated version of Specdrums’ signature music-centric wearable ring. The company seems to have passed the rocky point at which it laid off 45 employees and re-focussed on educational products. Now, Sphero says it plans to accelerate international growth. Though, it may have to compete with the likes of iRobot, which recently made its own push into the classroom.
