His children, his mates and the challenge of proving himself every year are key drivers for the City Rise Bombers swingman.
It is more than 20 years since the 39-year-old made his A grade basketball debut, aged 18.
At a time when people are dropping out of sport younger and younger, it is an impressive achievement.
Not only that, he has remained a key player in the league throughout.
His shot is still lethal, he knows how to get to the free-throw line and he has all the veteran tricks.
Keeping active through work - he is self-employed as Mr Green - has helped with that.
Along with feeling good physically, the sense of excitement remains as a new season begins today.
"I just grew up with basketball. It's been my main sport since I was a kid," Robinson said.
"As my kids came along I wanted to keep them going in it.
"I thought if I can still do it, it gets them more motivated to practise if they still see me doing it.
"Just the challenge, it's a social thing as well. Put yourself up against good teams and play good organised basketball.
"It's the best level we've got at the moment. You've got to play in it, otherwise you miss it.
"You hear about it and think `I wish I was there'."
Robinson began his club career in A reserve grade when King's High School entered a team in his final year at school.
He then joined the Mid City Magic along with friend Jason Frost, the duo having known Magic's Alf Arlidge.
It was with the Magic he won his only championship.
At the same time he was beginning an Otago Nuggets career in which he played more than 50 games in the National Basketball League.
Back at the club level he and some friends felt there was room for another club.
That marked the birth of the Bombers in the mid-2000s.
They made the final that first season, but let a nine-point lead slip in the final against the Magic.
Three finals have followed, but a championship in green eludes him.
Alongside playing, coaching now keeps him busy.
He is the assistant coach of both the Otago Gold Rush and the Otago men's team.
Alongside that, he coaches his three children - Asha (13), Bree (10) and Drew (8) - while wife Janis is a big helping hand.
But he is not ready to give playing away.
While older players were getting rarer, he noted there had still been a few around still going until recently.
"I think the guys that grow up with it and have a group of friends that play it are more likely to keep with it. It happens hear after year.
"If you shifted here as an individual and you don't have the group and the club backing, you might give it up a bit earlier.
"I feel a little bit responsible to keep turning up for the boys and make sure it's all ticking along all right. I can't leave it all up to Frosty."
