"It was a thrill to have access to those guys at the old Garden," said Robinson, who played hockey through his graduation from Tewksbury High School in 1987.
It was around that time - roughly 1988-89 - that Robinson's access to the Bruins grew. During one of his trips to the Garden, the young Robinson - still a teenager - was asked if he'd like to help out around the locker room. Among his most important tasks was filling up the water bottles for the Bruins bench.
"I just went in and it was kind of one of those things where you were there, so they asked, 'Hey, do you want to fill up the water bottles for the bench? Do you want to do this? Do you want to do that?'" said Robinson. "You just kind of start showing up more and more."
And ever since then, Robinson - affectionately known as Keto - has been showing up on pretty much a daily basis.
Working under the tutelage of former Bruins equipment manager Ken 'Doc' Fleger - "he was my idol, like a father figure" - Robinson was a locker room assistant for five years, before becoming the B's assistant equipment manager, a position he held for 17 seasons.
In 2010, Robinson became Boston's lead equipment manager and has served in that role for nearly 11 years with Jim 'Beets' Johnson and Matty Falconer as his assistants.
"It's been amazing," Robinson said of his three-plus decades working alongside some of the B's greatest players. "Especially Chief, I got to work with him for years [when he was director of road services]. You spend time traveling and around each other as much as that, you definitely get to know each other better, share stories.
"Just really, really an honor. Really cool to spend so much time with him and a lot of others that I got to work with."
And, of course, any time that Orr makes a visit, it's a day to remember.
"You always know that he's around," said Robinson. "It's still a thrill to say hello and catch up a little bit."
