Masensa ndi "mau" a loboti: popanda iwo, loboti silingathe kudzipeza lokha, kuzindikira zinthu, kumvetsetsa malo ake, kapena kuyanjana bwino ndi anthu. Chifukwa chake, zokambirana za maloboti amakono nthawi zambiri zimayang'ana paukadaulo wapamwamba wa masensa, zomwe zimapangitsa maloboti kukhala odziyimira pawokha, olondola, komanso osinthika.
Udindo wa Masensa mu Machitidwe a Robotic
Roboti kwenikweni imakhala ndi zigawo zitatu zazikulu: ma actuator (zipangizo zoyendera), ma controller (zipangizo zamakompyuta), ndi masensa (osonkhanitsa deta). Ma actuator amasuntha manja, mawilo, kapena miyendo ya loboti. Olamulira amakonza deta ndikupanga zisankho. Masensa amagwira ntchito ngati gwero la chidziwitso chomwe chimalumikiza lobotiyo ndi dziko lenileni. Popanda deta ya masensa, wolamulira amangotsatira malamulo "mwachimbulimbuli" ndipo sangathe kusintha malinga ndi kusintha kwa chilengedwe.
Masensa m'maloboti amagwira ntchito posintha zinthu zakuthupi—monga kuwala, kuthamanga, kutentha, mtunda, kapena mafunde a phokoso—kukhala zizindikiro zamagetsi zomwe kompyuta ingathe kuzikonza. Deta imeneyi imagwiritsidwa ntchito poyenda, kupanga mapu, kupewa zopinga, kuyeza mphamvu pogwira zinthu, komanso kusunga bwino.
Mitundu ya Masensa Otsogola mu Ma Robot
