I haven't been able to find any relevant text to this robot, but it appears to be able to detect an audience (via photo-electric cells in its eyes?), stand using motors in the base guided by the geometry of the arms holding onto a rigid post, delivers a recorded message via its loudspeaker mouth, then returns to a seated position when finished.

The “man machine” was built by László Zelenka (1902-1960; electrical and radio engineer) the “Hungarian Edison” and it’s futuristic body was designed by Sándor Bortnyik (1893–1976), the Hungarian avant-garde artist.
