Took it upon myself the monumental task of cramming 75 science/minute into a single roboport's construction area, though from the looks of it i'll need two to include raw material smelting.
In its current state it produces 6 of the sciences at 45/minute from 1 line of steel, 1 line of bricks, 1 line of coal, 1 pipe of oil, 1 pipe of water, 7 lines of iron and 7 lines of copper.
