Oh Kno it didn't! Tablet gets tested by Lego robot

With today's proliferation of tablets it can be hard to distinguish one device from the next. But here's something that sets the Kno Textbook Tablet apart (besides its big dual displays and focus on students): it's getting stress-tested by a Lego robot. The Kno product development team needed a way to automate tests of the ambient light sensor and the note-taking stylus' interaction with the LCD touch screen. So they built a Lego robotic arm (they give it the far less sexy name of "accelerated life test apparatus") to shoulder the repetitive work. In the behind-the-scenes video below, you'll see the arm directing the pen back and forth and up and down across a screen, while another robot makes the device itself go back and forth.
