No one said the “most modern robot” at a Russian technology event was a real robot, but it appears no one said it wasn’t either.

So, some journalists covering the state-sponsored event for children had a lot of questions when Robot Boris appeared on stage talking and dancing. He also could answer math equations.

Coverage on Russian state TV praised the “hi-tech robot” at the annual Proyektoria technology forum, The Guardian reports, even praising its intelligent dance moves.

Russian website TJournal questioned how the seemingly advanced robot was completed so quickly and no one knew about the design. The site also noted the robot's human-like clumsy movements and size — big enough for a person to fit inside.

Images on social media made it obvious that Boris was in fact a person wearing a suit, a "Alyosha Robot" costume by company Show Robots that costs about $3,700. One image from the event showed an exposed human neckline. Others showed the man actually playing the part of Boris.
