Mass production of fiber positioners is plotted at left. We produced a total of 7148 robots. A preproduction run of 440 units (not shown here) lasted from 2016 December–2017 March. Tooling and procedures were finalized by the time of a 2017 May manufacturing readiness review. Full production began in 2017 June. By fall 2017, all manufacturing startup issues had been resolved, and production accelerated to eventually exceed the planned cadence (500 units per month) by mid-2018.
