IG-88 Senses 7

IG-88 stood  at the  end of  the manufacturing  line, lis­tening  to the  sounds of  metal clinking,  hydraulic jets  spraying,  components  being  assembled,  lubricants  applied.  He  could not  smell, though  his chemical-analysis  tracers  detected  minor  concentrations  of  welding  com­pounds and aerosol sealants floating in the air.
