The news agency, MBKh Media, later appeared to show an actor in the robot suit just before the forum, which was held about 150 miles outside of Moscow.
A Russian state television channel has been left red-faced after filming a showcase of a pioneering robot which turned out to be a man in a suit.
A robot shown off on Russian TV stunned an audience of schoolchildren with abilities including dancing, walking, talking and solving maths problems. BBC reports that in a pic shared on social media, the person's neck was visible from inside the robot costume.
Forum organizers have said they used Boris to enliven the event, having him dance to a pop song, and they insist there was never any attempt to deceive people into thinking it was actually a robot.
Online Russian news outlet TJournal noted the lack of sensors, human-like movements and other discrepancies. For starters, he was nearly perfectly human-shaped and didn't have any external sensors. According to The Guardian, the "Alyosha the Robot" costume retails for about $3,800.More news: Trump's advisers struggle to explain deal he says he cut with Xi

On the website of the company behind the robot, it is described as being able to create "an nearly complete illusion that you have a real robot".
'Especially as at the forum they have the opportunity to look at the most modern robots'. On Wednesday morning, the television report was removed from Russia-24's YouTube channel but was uploaded again by early afternoon.
If this robot is what Russian Federation 24 reported, it would be an astonishing advance in robotics and a huge leap into the uncanny valley.
When approached for comment by the Guardian for comment the organizers claimed the show was not meant to trick people into believing Boris was a robot but rather that it was a "fun" way to generate interest in Stem fields.
