The blower drive pulleys (toothed belt type) on the supercharger drive on my old Chevy are black anodized...it increases durability by several times, compared to non-anodized pulleys (30k miles with anodizing vs 10k without).
I'm not sure how this relates to robots...but don't take such things too superficially.
