But the joy was short-lived and Scunthorpe levelled just six minutes later when Paul Hayes - who spent two years at the South Yorkshire club - headed home at the back post to earn his side a share of the spoils.
But Robins was pleased to see his men extend their unbeaten run to five games, without performing to their potential.
"It was very flat, I don't think it will bring the supporters back," said Robins.
"It's the first time we have played like that for a long time. But I can't criticise them too much.
"Sometimes you've got to say 'it's another point on the board' and when you've not played well it's a good point at that."
Maltese striker Daniel Bogdanovic was at the centre of everything that Barnsley did well and he was surprisingly substituted midway through the second half.
But Robins revealed that he is protecting Bogdanovic for a busy schedule ahead.
"Bogdanovic has had a tight groin for a couple of days," he said.
"He's not had a lot of practice and that's in the back of your mind. There's a lot of games coming up at Christmas and you have to try and protect what you have got because you can't bring anyone in at this stage."
Scunthorpe boss Nigel Adkins believes his decision to work with a small squad is paying dividends after they fought back for a point.
Adkins has one of the smallest playing staffs - in terms of numbers and budgets - in the division and he believes the team spirit is high as a result.
"I have tried to keep a small squad of players and not enhance it any further for the simple reason that we have got a great team spirit," Adkins said.
"They have shown that tonight. After going behind they showed great commitment and desire.
"We will keep supporting the players. We have got a good cohesive unit of players who are working very hard for each other and long may that continue."
Adkins changed his system for the clash, flooding the midfield with five players.
He added: "We came to make sure we got something. It is a way that we can work and it's a very big pitch so if you don't pack the midfield you leave yourselves very open to a team that have been bang in form.
"But we know playing this way is not negative."
