whats the name of this movie? PLEASE HELP?

i don't remember what its called or who plays in it all i remember is
what the movie about

is about this robot wanted to be human! so this robot went to this
place and this guy made the robot look like a human and but he
couldn't eat or feel anything so the robot man went back two times to
the place the guy gave him taste and feel or whatever! then robot man
falls in love with this lady and and they grow old together and then
at end this robot man and the lady were watching TV they had meeting
talked about this robot man and they made it official that the robot
man became human being but soon as they said it the robot man died! so
he didn't get to hear that he was human!

and I think i said I THINK the robot man was played as Robin Williams
