Mansfield manager David Flitcroft had to settle for a draw on his return to Swindon as Stags midfielder Will Atkinson was sent off.
Atkinson was on the end of a tough challenge from Marc Richards early on, and took his frustrations out on first Matt Taylor and later Keshi Anderson and picked up two yellow cards as a result, with the second coming in the 43rd minute.
Prior to the red, CJ Hamilton shot over and Danny Rose had a header well saved by Lawrence Vigouroux while Elijah Adebayo and Anderson were both denied at the other end.
Swindon were the more threatening in the second half, with substitute Kaiyne Woolery warming the gloves of Bobby Olejnik.
On-loan Fulham forward Adebayo had the best chance but could only divert a shot from close range wide of the post following a Jermaine McGlashan cross.
With eight minutes left, Taylor hit the post with a curled free-kick.
Flitcroft left Swindon to join Mansfield in March this year after winning 18 of his 35 league games in charge of the Robins.
