In 2010/11 he won the Cardiff Blues Academy Player of the Year Award having had an outstanding season and became the youngest ever player to represent the Cardiff Blues, when, aged 17 years and nine months, he lined up against the Ospreys in the LV= Cup.
Speaking of the signing Robinson said,
"I'm really pleased to get to stick around for a few years."
"It was an easy decision to make and I took the offer with both hands."
"This is the best rugby environment for me to be in and I've got a good group of friends here also, so I'm excited to be here."
"It does feel like a fresh start with Phil coming in and all the boys who are here feel it's a good environment to be in."
"It was a bit of whirlwind last season for me but things have sunk in now but now it's a new season and I'm just putting my head down and working hard."
"My ambition is to establish myself in the Blues team but competition is going to be tough with the quality back three players we have in the squad at the moment."
Cardiff Blues Director of Rugby Phil Davies added,
"I'm very excited that Harry has signed his first professional contract with the Blues."
"Having worked with him here for the last couple of weeks I can see that he is a player with massive potential."
"He's had a couple of outings for Wales whether that is for the Sevens or for Wales against the Barbarians and in Australia."
"Now his challenge is to play regional rugby week in week out and play rugby for Wales."
"He's certainly talented enough and applies himself well."
"I've been impressed with his attitude since he's come back from the tour."
Speaking of retaining players in the region Davies added,
"You're always going to get market forces that move players around, which you will never change, but I think it's vitally important that we keep players that are born and bred in the region here."
"We have to keep these young players in the region and develop them."
"Harry is at the start of his career as are a lot young players in the squad."
"They become the heartbeat of the team and you can see that players such as Bradley Davies, Sam Warburton, Lloyd Williams and Jamie Roberts have also come through the system."
"The people within the region relate to them because they are from the area."
