Ethan Jones returned to the side and fired Newtown into an early lead, before Jonathan Hood cancelled it out with a strike just before the break.
Dave Jones was hardly tested in the second period, with the lion’s share of the chances going the Robins way, but they couldn’t find a winner.
Five minutes from time the Robins had a penalty shout turned away, after Callum Roberts’ cross hit a defender, with the Robins players calling for a handball.
