Scotland were the pick of the northern hemisphere sides Down Under and swept all before them with victories over Samoa, Fiji and Australia.
Robinson's men are next in action against New Zealand, South Africa and Tonga in November and he insists they must continue to develop.
"It gives us positivity going into the next year," said Robinson.
"The guys should be excited about the forthcoming season and looking forward to being selected against New Zealand."
Scotland travelled to the southern hemisphere on the back of a disappointing domestic campaign, having picked up the Wooden Spoon in the RBS 6 Nations.
But they rocked the rugby world with their 9-6 win over the Wallabies in difficult conditions in Newcastle and continued their form in the south sea islands.
"I'm really delighted with what we have achieved on this trip," added Robinson.
"Three big shifts were put in by the team in incredible conditions.
"Right from the first day of arriving in Australia, everything has run smoothly and the players have interacted brilliantly; not just in the training we've done but also off the field.
"Our collective performances were good in all three games and to see the new caps perform as well as they did was just great."
"In the autumn we start with New Zealand and that's a real challenge. If we want to be successful we have to push the boundaries and play against the best teams.
"We've got South Africa as our second game in the autumn and we will have to stand toe-to-toe with them.
"Tonga are a side we played recently in an 'A' game but we know they have improved as a team."
