Robot wars: Nvidia unveils stunning Wall-E-style robot sparking Boston Dynamics to hit back with cartwheeling humanoid

For any homeowner, having a helpful robot companion around the home is the stuff of sci-fi-worthy dreams. But American tech firm Nvidia is now among the companies keen to make this a reality. In California on Tuesday, the chip giant unveiled Blue, a cute advanced AI-powered robot with two legs, just 3 feet tall. Footage shows Blue – which looks like the robot from the Pixar classic Wall-E – walk onto the stage as it's introduced by Nvidia CEO Jensen Huang. 'Tell me that wasn't amazing,' Huang says to the audience, as Blue waddles up to him with a similar gait to a duck.
