[1] Having come to London on the advice of Dr. Henry Pemberton (1694–1771), who had recognised Robins's talents,[1] for a time he maintained himself by teaching mathematics, but soon devoted himself to engineering and the study of fortification.
He compared the results of his theory with experimental determinations of the ranges of mortars and cannon, and gave practical maxims for the management of artillery.
[2] However, the work of Robins still served as an important piece of technical information that helped the later advancement of the Prussian artillery, especially of its improvement in accuracy, a big step forwards that the book turned out to be a shot in the arm of the ambitious Frederick the Great who determined to vault the status and power of Prussian artillery to the top among other European armies.
He wrote pamphlets in support of the opposition to Sir Robert Walpole, and was secretary of a committee appointed by the House of Commons to enquire into the conduct of that minister.
He also wrote a preface to the Report on the Proceedings of the Board of General Officers on their Examination into the Conduct of Lieutenant-General Sir John Cope, in which he gave an apology for the battle of Prestonpans.
