I’m very impressed with the technology behind this, very compelling, I can see we’re getting closer to anti-gravity vehicle soon based on similar concept. By the way, if you’re on an airplane that encounter turbolance or very bummy and shakky, don’t worry because the same technology are being use to balance it, the plane will not loose its balance and roll over or crashed LOL  AND NO! This is not a cheap toy robot you would find at the flea market or toys store made in China LOL this is real technology robots
