Robson was born at Kirkby Thore, Westmorland, and initially educated at Appleby, five miles from his father’s parish of Warcop. Like many scholars from north-west England, he progressed to Queen’s College, Oxford, but completed his first degree at a neighbouring institution, St. Edmund Hall. He may have been ordained with a view to remaining an academic, since most university fellowships were then open only to the clergy. However, in 1610, less than two years after taking up a post at Caius College, Cambridge, Robson was instituted rector of Morpeth. In 1614 he also took charge of the parish of Whalton, and in the same year he was admitted to the York convocation. It is not known how he became one of James I’s chaplains, but this dramatic promotion in turn led to his inclusion from 1620 on the High Commission for the province of York.
Although Robson was now emerging as an influential figure in Northumberland, it is nevertheless surprising that he was elected to represent Morpeth in the 1621 Parliament. First, there was already a well-established convention that clergy should not sit in the Commons. Secondly, the borough normally returned outsiders nominated by the principal local landowner, the Catholic Lord William Howard of Naworth. However, while Robson was undoubtedly known to Howard, who was obliged to pay him tithes, there is no evidence of a close personal relationship, and this politically experienced peer is unlikely to have recommended a candidate whose eligibility was in doubt. Rather, it seems that on this occasion the Morpeth voters ignored Howard’s wishes, probably in protest at his heavy-handed enforcement of his tenurial privileges, and instead elected men of local standing who might promote the borough’s interests.
In 1623 Robson became a prebendary of Durham cathedral, probably through the influence of his father-in-law, John Cradock, the diocesan chancellor. As one of Durham’s resident canons, Robson was directly involved with the Arminian practices introduced to the cathedral’s worship during this decade under the aegis of the bishop, Richard Neile, and his protégé John Cosin. Indeed, his eldest son was the first child baptized in their new, highly ornamented font.
Robson became a magistrate in both Northumberland and county Durham in 1630, and remained a member of the northern High Commission throughout the following decade, though he obtained no further ecclesiastical preferment. In 1638 he sent both his sons to Peterhouse, Cambridge, where Cosin was now the master.
