England retained the Calcutta Cup after a topsy-turvy war of attrition ended in a 15-15 draw at Murrayfield.
"You've got to work hard for your tries," added Robinson, who narrowly failed to become the first Englishman to lead Scotland to a Calcutta Cup victory "When we put England under pressure there were a couple of occasions when we chose the wrong options. We're learning and what you saw was an improvement from Italy. It will come."
It was the first draw in the fixture since 1989, when Scotland coach Robinson made his only appearance as a player.
Scotland dominated possession and territory, especially in the first half, but were let down again by their inability to turn pressure into tries.
The result means Scotland will finish with the wooden spoon if they fail to win in Ireland next Saturday.
"I'm really looking forward to Ireland," said Robinson. "The players took another step forward this week.
"I thought we played positive rugby, I thought we moved England around and, credit to their defence, they held up well.
"I thought we created opportunities and I thought the way we tried to play with the counter attack and some of the attacking plays we put on was very good.
"Unfortunately, again, we couldn't get over the line. But I'm really, really pleased with the way the team tried to play and played."
