Ko te karetao whakakikorua i werohia he punaha whakahaere, he punaha taraiwa, he punaha whakahaere. Ko nga mahinga mahi me nga punaha taraiwa kua hangaia hei mahi i nga mahi noa o te ringa, ma te whakamahi i te mana pneumatic, hydraulic ranei hei taraiwa i nga waahanga miihini me te whakatutuki i te mahi kato. Ko te punaha whakahaere e whakahaere ana i te punaha taraiwa, me te whakarite kia mahi te punaha whakahaere i runga i te tikanga kua whakaritea. Te tango i tetahi punaha whakahaere karetao ngawari hei tauira:
Tangata -Atanga Miihini ←→ Whakatuwheratia te Waitohu Katoa ←→ Microcontroller ←→ Waitohu Karetao Miihini Whakairi ←→ Waitohu Vave Various ←→ Riko Whakaoti
Ka mahi te kaiwhakahaere ma te atanga -tangata. Ka whiwhi te karetao i te tohu ka taea mai i te miihini whakakikorua, ka tapahia te tohu katinga o te miihini whakakikorua hei whakapumau i te haumaru o te kohi hua. Whai muri i te kohi i te hua, ka hoki ano te karetao i te mahi a te miihini whakakikorua. Ko te wero hoahoa o te punaha whakahaere kei roto i te hononga mahi i waenga i te karetao me te miihini werohanga. I raro i te whakahau a te punaha whakahaere, ka oti i te karetao nga momo mahi i runga i te tikanga mahi kua whakaritea, na reira ka tango i te hua werohia-mai i te pokepokea ai, ka whakawhitia ki te waahi kua tohua, ki te mahi whakaputa ka whai ake. I te wa e hoahoa ana, me whakatauhia te punaha whakahaere i runga i te mahi o te miihini miihini werohanga, nga tikanga whakahaere me nga whakaritenga o te robot, me te ahua me te taumaha o te hua.
