Prior to the start of the Championship, Scotland suffered back-to-back defeats at the World Cup to England and Argentina while Sunday's defeat to France ensures Robinson has an unenviable record of two wins from 13 RBS 6 Nations outings.
But Wright, who saw his Under-20 side lose a third straight match at the weekend, believes Robinson must be given more time.
"I think we've got to stick with him. I think the players like him," he said.
"I think the biggest majority of the public like the guy. They can see he's got real passion for the team.
"He is improving the team, there's no doubt about it. The one thing we've got to learn to do is win games.
"But, despite the defeat, we go over to Ireland with a lot of confidence now.
"Andy is his own biggest critic. The results are very important, but what you've also got to look at is how we're performing, how he's brought the young guys through."
