The Cubelets App has two main functions: Remote Control and Personality Swap. We’ve already introduced you to the Personality Swaps, but have you begun to use Remote Control in your classroom? There’s a hidden feature I want to highlight for you because it’s not the first application people think of when they see a title like Remote Control: gathering data about our robot constructions. (Before you continue, it’s a good idea to make sure you understand how data travels through Cubelets by either reading this blog post or taking the Cubelets 102 (free) online workshop.) As you already know, you can easily gather information about how data is traveling through a Cubelets robot construction using the Bar Graph Cubelet. The Bar Graph is also a screen-free way to gather data about your Cubelets constructions. It simplifies the numbers into a 1-10 scale, as opposed to numbers between 1-255, so it makes data flow conversations available for students who are still emergent mathematicians. However, there is one thing Remote Control can do that Bar Graph Cubelets cannot: collect information about every Cubelet in a robot construction at the same time. By screenshotting the data in Remote Control, students can very quickly gather static data to analyze later. As students build more complex creations, especially by adding multiple SENSE Cubelets, it’s more important that they check their assumptions about how the data is flowing through their robot constructions. In general, the five main states of a two-SENSE robot are:
