Mick Harford has joined Swindon as assistant manager to boss Andy King.
Harford's role will be reviewed at the end of the season
Harford had previously been director of football at Luton and caretaker boss at Nottingham Forest this season, and said: "It's nice to finally be here.
"Andy is a very good friend - working together is something we have always wanted to do. It will be until the end of the season, when we will review it.
"I will do the coaching, and just assist Andy in any way I can. Hopefully we can have a bit of success."
Earlier this month, King had dismissed reports that he was set to become director of football in order for Harford to take charge of the team.
But the Robins manager had been without an assistant since Mike Walsh left the club at the beginning of February.
Harford continued: "Swindon are in a good position in the league at the moment - I see no reason why we can't make the play-offs.
"I know this league very well from my time at Luton, and I know the sort of players involved and the standard of football played at this level.
"Luton are doing well at the moment, as are Hull and I honestly believe they are home and dry - it is now a fight for the play-offs.
"It is an inconsistent league - most of the teams are very similar in capability, so it should be very interesting.
"Andy is still trying to get players in and strengthen the team to help get that play-off spot."
