A T.Rex at the science museum.

At half past eight PM, a human dressed in  a dinosaur costume, specifically a T.Rex appears magically in illusionism, from somewhere inside, with huge grunts and roars, roaming ergotically the entire hallway lobby of the science museum, Does he span the whole surface area, in his quest to create the wrong images of the T.Rex? Maybe yes and maybe no, while some women scream and run to safety away from a formidable mass of polymer, and mechanical grunts, I realized that the language was incorrect and the deception obvious in the visible feet of a man.
Here are images:

Maybe robotics with a pure auto navigating robot would be more appropriate, why not use BEAM robotics?
