When will robots/androids be available for educational/training purposes?
In the beginning there were softbots, software robots or virtual robots, before there were hardbots, hardware robots or physical robots. BTW, the more politically correct term for android is humanoid, or humanoid robot, in deference to gynoids [1].
There has already been considerable research into “intelligent tutoring systems” [2] otherwise known as “pedagogical agents” [3].
