问题 One　study　conducted　by　a　psychologist(121)of　interviewing　workers　before　and　after　the　installation　of　a　robot.　The　robot　was　used　to　control　a　matching　process　of　stamping　and　assembling　metal　parts.　Prior　to　installation,　much　of　the　work　done　by　skilled　machinists.　After　installation,　the　robot　did　the　work,　but　the　workers　controlled　the　robot　through　the　robot　through　a　control　panel.　The　results　of　the　study　indicated　that　the　workers　praised　the　robot(122)eliminating　the　physical　labor　and　fatigue(123)the　manual　operation,　but　complained　of　more　and　continued　stress.　Prior　to　installation　of　the　robot,　there　was　time　for　talking　or　short　periods　of　relaxation　between　jobs.　Now,　however,　because　of　the　speed　of　the　robot,　there　was　a　need　for　constant　scanning　and　monitoring　of　the　operation(124)performed　by　the　robot　has　the　installation　of　the　robot　created　a　better　work　environment?　Has　the　change　from　physical　labor　to　mental　stress　resulted　in　an　improved(125)of　life?　Much　additional　research　is　necessary.
