Robinson hails Scotland courage
Jim Hamilton was the hero for Scotland scoring his maiden international try while eight points from the boot of Dan Parks proved equally as important.
However Scotland were made to work for the win with Felipe Contepomi and Martin Rodriguez kicking two and one penalties respectively on a rain-drenched night.
And while full of praise for his team Robinson - who was appointed Scotland coach a year ago - admits there a plenty of lessons to be learnt.
"We controlled the first half well but we didn't control the scoreboard. I was a bit concerned that we went in at half-time only four points ahead," said Robinson.
"We've got to learn when are as dominant as we were that we are 15 points clear in the future. But I am delighted for everyone involved in Scottish rugby.
"It is hard work and the guys put in a lot of effort to achieve something very special. I am delighted for the players because they put in a lot of effort.
"Some days you win ugly and some days you go and win through courage I think we won with courage."
