This review shows the Sphero SPRK Edition robot and SPRK app are a great introduction to robotics, coding, and STEM principles. The SPRK app lets kids give their robot orders with visual blocks representing code (like Spark) and later move on to Sphero’s own C-based language called OVAL. Sphero’s clear shell allows users to see the immediate connection between the program they created and how the guts of their Sphero work and react.
While not transparent, the Sphero 2.0 can use this same software and does not scratch as easily. You can control it using a less than $100 Android tablet.
