Robot toys aren't what you'd normally expect from Microsoft's developer-focused Build conference, but that's just what the company served up today. In a chat about developer tools, Microsoft's VP of Web Services Antoine Leblond demoed a version of Lego Education's unreleased Mindstorms EV3 platform using -- what else? -- a brick-built robot and a Surface tablet. Citing the Win RT APIs that let users interact with device-specific protocols (i.e., USB, Bluetooth, etc.) Leblond was able to stream live video of his face, using a separate Windows tablet, to the tank-like franken-toy. All whimsy aside, this MS / Lego collaboration's less about giving kids a neat, remote spying tool and more about making programming fun and approachable. You know, STEM stuff. And we're all for it.
