And with the Six Nations opener with England just two months away, SRU chief executive Mark Dodson has confirmed that a temporary appointment could be the best way forward for Scotland.
"We have already received a number of applications for the job," said Dodson.
"We are reviewing these as well as looking at home and abroad for the best candidate to take Scotland forward to the Rugby World Cup.
"We have the RBS Six Nations just round the corner and, given the timescales involved, we are looking at the possibility of an interim appointment as we don't want to rush into making the decision.
"The most important thing we can do is get someone in to take the team forward for the long term."
Dodson's comments appear to pave the way for Scott Johnson to step up to the role in time for the Six Nations while the search continues for Robinson's long-term replacement.
The former Wales, USA and Ospreys boss joined the SRU as Robinson's assistant earlier this year and is still under contract at Murrayfield.
Johnson hasn't yet been interviewed for the post but his is keen to find out where he stands sooner rather than later.
"I have not had a chance to speak to the officials, but I intend to in the next week or so," said Johnson, who has been heavily linked with the job alongside Sean Lineen and Nick Mallett.
"That will decide where I am placed in the job and if the job suits me, and if it suits them for me to take it. I am secure in the fact that I have come here for a couple of years and I have only just started.
"There are plenty of good things in Scotland and plenty of hard working rugby people and there are plenty of good players.
"We need to start developing a game that suits us to play."
