Nrog rau kev txhim kho thev naus laus zis, cov neeg hlau pib ua haujlwm ntau dua thiab nyuaj dua. Cov haujlwm no qee zaum xav kom cov neeg ua haujlwm cuam tshuam txhua lub sijhawm, yog li kev nyab xeeb ntawm tib neeg-khoos phis tawj sib cuam tshuam yog qhov teeb meem tseem ceeb hauv qhov no. Txhawm rau kom muaj kev nyab xeeb, tus tswj xyuas yuav tsum kuaj xyuas seb puas muaj kev sib tsoo ntawm cov neeg hlau thiab cov neeg ua haujlwm hauv lub sijhawm tiag tiag, thiab xyuas kom meej tias cov neeg ua haujlwm yuav tsis raug mob ntawm kev sib tsoo los ntawm kev tswj cov tswv yim. Tam sim no, feem ntau ntawm kev sib tsoo lossis kev sib tsoo quab yuam yog ua tiav los ntawm kev ntxiv cov khoom siv sab nraud.
Muaj ntau txoj hauv kev los txheeb xyuas kev sib tsoo. Lub dab teg quab yuam sensor yog siv los txheeb xyuas kev sib tsoo: nws tuaj yeem txheeb xyuas qhov sib tsoo quab yuam ntawm qhov kawg ntawm tes tuav, tab sis nws tsis tuaj yeem ntes kev sib tsoo ntawm lwm qhov ntawm tus neeg hlau. Qhov kev tshawb nrhiav tau txwv. Feem ntau, nws yog siv los xyuas qhov kev sib tsoo quab yuam ntawm qhov kawg ntawm kev tuav tes, xws li kev sib tsoo quab yuam, sib dhos quab yuam, thiab lwm yam. Perceived daim tawv nqaij yog siv los soj ntsuam kev sib tsoo. Los ntawm kev npog cov tawv nqaij nkag siab thoob plaws lub cev ntawm tus neeg hlau, kev sib tsoo ntawm ib qho twg tuaj yeem kuaj pom. Txawm li cas los xij, qhov tsis zoo yog tias cov xaim yog qhov nyuaj, thiab muaj peev xwm tiv thaiv kev cuam tshuam tsis zoo. Nyob rau hauv tag nrho cov txheej txheem, tus processor kuj tau nce tus nqi ntawm kev xam kom pom kev sib tsoo los ntawm lub cev muaj zog tam sim no los yog cov lus tawm tswv yim torque: qhov no yog kev sib tsoo cov phiaj xwm dav siv nyob rau hauv ntau yam kev lag luam robots, thiab tsis xav tau sensors ntxiv. Qhov zoo dua yog tias qhov kev tshawb pom ntau tuaj yeem npog tag nrho saum npoo ntawm tus neeg hlau.
