I am suspicious because that's the most near-human walk of a robot so far. People don't think about it because it's a just a walk. So far all the robots you see that can do a bi-pedal walk don't come close to replicating a human walk because it's a lot more complicated having all the technology balanced just right. The EX robots that have been displayed before are just upper body parts. That's why you see a lot of walking robots looking like they're stooping. I'm on the skeptical side because that would be a huge achievement to accomplish that. If Americans are paranoid over Chinese putting an assault rifle on robot dog's back, they'll go insane thinking China is secretly replacing their friends and family with pro-CCP robots. China should make one look like Marco Rubio and publicly display it and watch the fun ensue in the US...
