One of the keys to automating everything is achieving economies of scale for both the set of automated models used & for individual factories. If we can make “chopping machine”, “stirring machine” etc. that all drop off the dirty parts from different runs to the same set of cleaning gear then it helps both of those goals.

Consider also human prep activities that involve frequent hand washing and/or wearing disposable gloves. Robot appendages may be able to done some type of temporary plastic covers that are washable & reusable.
