LEGO and Amazon have announced a contest for creating voice controlled robots using Alexa and LEGO MINDSTORMS EV3. And the best part is that it builds on ev3dev!
There are some substantial prizes and lots of smaller prizes. There is even a special category for 13 to 17 year-olds. And the first 100 people to submit an entry are even eligible for a prize.
