honda made the robot that can climb ladders, dance etc. matter tansmition is to power intensive for it to be developed with current technology. ( it has been done but way to expensive a power bill for anything larger than small molecules ) the best prediction was Jules Verne. the Nautilus, a nuclear powered submarine. about 40 years before subs were first built. and 60 years before nuclear power was developed. though he had it fusion powered ( "power of the sun" ) and we haven't controlled fusion yet, only fission.
