This machine would have been designed regardless of minimum wage salary.
We (society) are increasing the minimum wage with out figuring out what to do with all the unemployable people that do not have the education, experience, or in some cases the talent to command a wage that high. The belief is that companies will just "eat" the added costs because they are simply greedy today and can "afford" to pay more, these types of robots prove this will not be the result and what will be the result is massive unemployment
Massive unemployment for certain jobs is unavoidable at this point. Serves no purpose to condemn workers for several decades to survive with really low salaries. If there are greater efficiencies due to automation, everyone should be participating on the value created (insert basic income theories here or other similar policies)
As for the minimum wage... what can I say. Going to 15$ doesn't seem to be the end of the world. Adjusting for inflation, current minimum wage is really on lowest value for the decade and about median for the last 60 years. Considering how much economy has expanded in 60 years, seems like a very raw deal for workers in certain sectors.
