Ko ngā rauemi i keria e te keri ko te oneone, te waro, te paru, te oneone me te toka i muri i te wetewete i mua. E ai ki te whanaketanga o ngā mīhini hanga i ngā tau tata nei, he tere te whanaketanga o ngā keri, ā, kua noho ko ngā keri tētahi o ngā mīhini hanga tino nui i roto i te hanganga hangarau.
Te whakatupuranga tuatahi o ngā keri: nā te putanga mai o ngā motuka hiko me ngā miihini tahunga ā-roto i whai taputapu hiko matatau, ā, he pai hoki ngā taputapu e tika ana mō ngā keri, nō reira i whānau mai ai ngā momo hua keri, tētahi i muri i tētahi. I te tau 1899, i puta mai te keri hiko tuatahi. I muri i te Pakanga Tuatahi o te Ao, i whakamahia anō hoki ngā miihini tīhiera i roto i ngā keri. Ko tēnei keri mīhini e whakahaerehia ana e te miihini tīhiera (te motuka hiko rānei) te whakatupuranga tuatahi o ngā keri.
Te whakatupuranga tuarua o ngā keri: Nā te whakamahinga whānui o te hangarau waipēhi, he taputapu tuku pūtaiao ake, he taputapu whaihua ake hoki te keri. Ko te tuku waipēhi hei utu mō te tuku mīhini he peke nui i roto i te hangarau keri. I whānau te keri waipēhi tuatahi i Tiamana i te tau 1950. Ko te tuku waipēhi mīhini te whakatupuranga tuarua o ngā keri.
Te whakatupuranga tuatoru o ngā keri: Mā te whānui o te whakamahinga o te hangarau hiko, inā koa te hangarau rorohiko, ka taea e te keri te whai pūnaha whakahaere aunoa, ā, ka āwhina hoki i te keri kia whanake i te huarahi mahi teitei, aunoatanga me te mohio. I puta te whanaketanga o te mechatronics i te tau 1965 pea, ā, ko te whakaurunga o te hangarau mechatronics ki ngā keri waipēhi i hangaia i te tau 1985 pea, i te wā ko te kaupapa matua he penapena hiko. Ko ngā hiko keri te tohu o te whakatupuranga tuatoru o ngā keri.
Ko ngā wāhanga o te keri he mea hanga ki ngā wāhanga e rua: ngā wāhanga miihini me ngā wāhanga hiko.
1. Ko ngā wāhanga mīhini he wāhanga mīhini anake hei tautoko i te hiko, tae atu ki ngā papu waipēhi, ngā peere hopu, ngā pūma, ngā ara hiko, ngā mīhini, me ētahi atu.
2. Ko ngā taputapu hiko te wāhanga whakahaere taraiwa o te keri, e whakamahia ana hei taraiwa i ngā wāhanga miihini kia taea ai te mahi tika, tae atu ki te putanga rorohiko, te kaiwhakahaere rere waipēhi, te pūoko koki, te mita tīhiera, te whakakā, te pana mura, te papu momi hinu, me ētahi atu.
He mea tautoko ngā wāhanga mīhini me te wāhanga whakahaere taraiwa tetahi ki tetahi. Ka whakamahia te wāhanga whakahaere hiko hei taraiwa me te whakarite i te mahi whai hua o ia wāhanga mīhini. Ka tukuna te āhua o te wāhanga mīhini ki te wāhanga whakahaere hiko mā roto i ngā wāhanga hiko, kia pai ake ai te whakarite i te mahi a te keri kia eke ki tōna tino pai o te mahi.
Ko te taputapu mahi te wāhanga matua o te keri waipēhi. Ko te nuinga o te wā e whakamahia ana hei keri i te oneone i raro i te mata aukati, engari ka taea hoki e ia te keri i te oneone i raro i te teitei tapahi mōrahi. Haunga te keri, te whakatō me te uta, ka taea hoki e ia te mahi i ngā mahi whakatikatika papa ngāwari. He pai te mahi keri mō te keri i te oneone o te taumata Ⅰ~Ⅳ, ā, me whakamahi te hama waipēhi, te tikanga pupuhi rānei mō te taumata Ⅴ i runga ake.
Ko te taputapu mahi backhoe he mea tito mai i te pūma, te rākau, te peere, te rōra, te tokotoko hono, me ngā paipa waipēhi o te taputapu mahi tae atu ki te rango pūma, te rango rākau me te rango peere.
