The 34-year-old midfielder made his debut in the opening game of the term against Kilmarnock but missed the subsequent 10 weeks with a knee injury. However, the Scotland internationalist played the final 25 minutes of Aberdeen's 1-0 win against Dundee United last Saturday and is back in the manager's plans.
"What Barry brings is an ability to affect and to improve people around him," said McInnes ahead of the trip to Hibernian. "He has got plenty of experience and it's important we use his experience as well as his ability. We still have work to do to get him back up to speed but it's great to have him around the training ground again. He really does have a big influence on the side."
During Robson's absence, the likes of Ryan Jack and Nicky Low pressed their own claims but McInnes insists they need not worry if they are forced out of the team. "What it indicates is that we have got real strength," he said. "The young ones have come in and shown their worth. But they have not been discarded because a couple of boys are back. They have nothing to feel low about. They have shown that, if needed, they can come in and do a job."
