"The FW43 is not especially well suited to this kind of corner, but we have a few ideas to improve the car in this regard and so we will have a busy Friday [in practice]."
Reflecting on the "excitement" of recent races, Robson added: "We enjoyed a very good weekend in Mugello but were very disappointed not to score any points.
"However, there were a lot of positives to come out of the last race weekend and our job here in Russia is to continue the good work, build on the momentum and understand how to apply the experience to the streets of Sochi.
"Traditionally we have found the tyres difficult to get working on the smooth surface, however, this year Pirelli have brought their softest compounds, and this may make things easier as well as opening up a greater variety of strategies on Sunday."
Russell also feels Sochi will prove problematic but, like Robson, is hoping a few recent indicators will at least ease the expected downsides.
"Russia is a circuit that on paper won’t suit us as much as Mugello," said Russell. "But we have learnt some things with the set-up in the recent weeks that I hope will allow us to be more competitive with our nearest rivals."
