Saracens back-rower Kelly Brown has been tipped to be granted the honour, having been in line for the role before suffering a broken leg before the RBS 6 Nations, when Edinburgh hooker Ross Ford assumed the leadership.
With Brown available again, Ford's run of eight matches in charge could come to an end for the November EMC autumn Test with New Zealand.
Robinson has informed his players of his decision, which will be publicly announced on the final day of the squad's training camp in St Andrews, with Blair promising the chosen skipper will not be short of advice should it be required.
Blair, who has 83 caps and has led Scotland on 14 occasions, said: "When you're young you think of playing for Scotland, but the honour of leading them out is a massive thing.
"There's a lot of people watching you, a lot of onus is on how you deal with certain situations, the decisions you make on the pitch as well.
"Whoever is captain will get a lot of support from guys around them.
"There are guys within the team and squad who have plenty of caps and experience.
"It's not so much a situation now where it's just one person. It is a group of people.
He added: "It's a results game. There's only so long you can talk about potential and playing well in games, but not quite doing enough.
"We were very positive with how things went in the summer. All three games were close games and we came out on top."
