LEGO Robot Flushes the Toilet... Now 'That's' APPLIED STEM Learning!

This NXT project elevates LEGO Robotics to a level far beyond a First LEGO League Challenge. Why must kids apply their robotics learning to contrived,  pretend engineering scenarios? Here's an example of a robot tasked to perform a real-world, full scale, human need! Doesn't this elevate LEGO Robotics-based  learning to a higher, more authentic, and ultimately  - more educational  level? I think this project and others like it, contextualized at this level of real-world immediacy,  point the way to an even better LEGO Robotics-based world of learning opportunities!
