You may not have been able to play with Lego in school, but your kids can. Lego Education has revealed the WeDo 2.0 robotics kit aimed at elementary school students, over eight years after launching the original WeDo. As before, it's designed to teach kids the basics of robotics, thanks to the Mindstorm-like sets. The new kit also replaces the old USB cables with a Bluetooth LE hub that connects to the motors and tilt sensors. The whole thing is driven by a tablet-based drag-and-drop interface that helps kids code basic robotics apps.
