The right-sided raider, given a free transfer by Charlton Athletic two weeks ago, was named by Bluebirds boss Lennie Lawrence as a target in the build-up to the play-off semi-finals.
And Robinson has admitted he does want talks with Lawrence and that City are the sort of club he would like to finish his career with.
"I would like to come down to Cardiff and look at the whole package," he told Wales on Sunday.
"Although I realise that Lennie Lawrence has more important things on his mind at the moment than John Robinson.
"But it was nice to hear that Cardiff are interested in me.
"My ears pricked up when I heard of their interest.
"They are ambitious and can be a massive, massive club."
Robinson was at the Valley for 11 years, but was granted a free transfer by boss Alan Curbishley because of the outstanding service he has given the club.
He's only 31 - and his fitness and energy down the right-hand flank would be an asset to the Bluebirds, whether they are playing First or Second Division football next term.
In fact, Robinson reckons he would still be comfortably within Mark Hughes's Wales plans had he not decided to call time on his international career for personal reasons last year.
"I think I would still be involved had I not taken it out of their hands," he said.
"I still feel as fit as ever and I have more than a few good years left in the tank yet.
"And when it comes to picking a new club, I'll not be looking at the vision of that particular set-up. I think Lennie Lawrence and Sam Hammam are my type of football people. I reckon Hammam is a fantastic chairman.
"He puts his money where his mouth is and his heart and soul into it all. You can see he's desperate to get the club where it belongs.
"He and Lennie are the sort who have gone into Cardiff and said, `Okay, let's see if we can get them somewhere they have never been before'.
"With managers I look for someone I can relate to, someone who is not afraid to listen to other opinions.
"Some professionals are interested primarily in the money or the location.
"For me it's all about it feeling right and the ambition being there.
"I would be prepared to relocate to Cardiff. I know the area well because I have been down there many times before.
"I am hoping the club can pull it off in the play-off final - I was chuffed to see them get through.
"But, to be honest, if it came down to it, I would not be bothered at all at dropping down a couple of divisions so long as everyone still knows where they want to go and the direction is there.
"I'm the sort of player who likes to have an affection for whatever club I play for.
"I don't want to rush things. But what I do want is to get the situation sorted out well before pre-season so I can do all the work and settle in."
Robinson admitted that some people may be suspicious as to why Curbishley opted to release him.
But he spelt out the precise situation that led to the Addicks boss calling time on his career in south London.
"I had a great relationship with Curbs," said Robinson.
"But he told me that I probably wouldn't get that much time on the field for the first team next season, all things being well.
"Rather than allow me to stagnate in the reserves he genuinely felt it would be better for me if I sought a new challenge and I agree with that.
"At Charlton we had a 10-year plan. I'd would like to think I had a big part to play in helping us achieve that well ahead of schedule."
