Robinson is contracted until the 2015 World Cup, but may believe he has taken Scotland as far as possible following two wins in 15 Six Nations matches, each coming on the final weekend of the championship in the last two years, and the worst sequence of results since 1998.
Robinson said: "I'm still contracted until 2015. I'm going away to reflect on the Six Nations and reflect on the future, in terms of the positivity that we have, the players we have and the way forward - and putting a plan together for the way forward."
There was little positive the former Bath and England boss could grasp at during a disjointed display at the Stadio Olimpico as his side remained without a victory since the September 14 defeat of Georgia at a World Cup where Scotland went out in the group stages for the first time.
The emergence of young players such as David Denton and Stuart Hogg may encourage Robinson to continue, but he made it clear the decision will follow an in-depth review of the championship which he will present to Scottish Rugby Union chief executive Mark Dodson.
Robinson added: "We'll be doing a debrief of the Six Nations and then I'll be meeting with Mark Dodson to go through that.
"There is not a set time scale on that. There's a lot to take in in terms of what's happened and it's about looking at the future and what's best for the future.
"Now's not the time to be discussing that, with the feelings that everybody has.
"The time to be discussing that we'll be in the next couple of weeks."
