Raws li kev lag luam thiab tag nrho cov chav kawm ntawm thev naus laus zis, robotics tau hloov pauv sai thiab nce qib. Txawm hais tias koj yog ib tus neeg nyiam ua haujlwm lossis tus kws tshaj lij robotics, koj yuav tsum paub txhua yam hauv thiab tawm. Qee zaum, koj yuav tsum paub yuav ua li cas xaiv ntawm ntau yam sib txawv.
Xws li yog rooj plaub nrog robots. Tsis muaj teeb meem npaum li cas tus neeg hlau cov pob qij txha yuav ua tau, koj xav tau cov khoom tsim nyog los muab tag nrho cov hlau thiab yas txav, quab yuam thiab ntau yam.
Hom neeg hlau motors twg muaj?
Muaj ntau pawg neeg hlau tsav. Txhua tus muaj sub-types thiab lawv tus kheej daim ntawv thov thiab qhov zoo. Nov yog cov ntsiab lus ntawm cov hom muaj niaj hnub no.
Robotic Actuators
Muaj peb hom actuators:
- Pneumatic actuators:lawv siv compressed cua ua haujlwm. Nrog ob peb qhov chaw txav, lawv txhim khu kev qha thiab yooj yim los tswj. Lawv tswj tsis tau qhov ceev, txoj hauj lwm, thiab qhov tseeb raws li lwm hom, tab sis lawv yog qhov zoo tagnrho rau cov khoom lag luam xws li khaws thiab thauj khoom.
- Hydraulic actuators:Qhov no yog qhov kev xaiv zoo rau cov neeg hlau loj uas nqa cov khoom hnyav. Lawv siv cov kua roj twj tso kua mis es tsis txhob siv cua los ua kom muaj zog. Thaum loj dua thiab nrov dua li lwm hom, lawv yog qhov tseeb - tab sis cov dej xau tuaj yeem tshwm sim dhau sijhawm.
- Hluav taws xob actuators:hluav taws xob motors hloov hluav taws xob hluav taws xob mus rau hauv lub tshuab hluav taws xob. Cov no yog hom ntau tshaj plaws nyob rau hauv txhua pawg neeg hlau niaj hnub no, vim tias hluav taws xob yog ib qho khoom siv ntau. Lawv kuj ua haujlwm zoo nyob rau hauv cov neeg hlau ntawm txhua qhov ntau thiab tsawg, muaj ntau qhov sib piv rau lawv cov khoom siv hluav taws xob, thiab yooj yim los tswj nrog yuav luag tsis muaj kuab paug.
Txawm hais tias hluav taws xob actuators yog qhov ntau tshaj plaws thiab muaj qhov dav tshaj plaws ntawm kev ua haujlwm hauv cov neeg hlau, lawv tuaj yeem ua rau muaj kev pheej hmoo hauv ib puag ncig uas muaj cov khoom tawg. Lawv kuj xav tau ib qho kev hais kom ua ntau dua li lwm hom tsav tsheb.
Hluav taws xob cov Motors
Nyob rau hauv qeb ntawm hluav taws xob motors, muaj ntau yam sib txawv. Pawg no suav nrog cov hom hauv qab no:
- Alternating Current (AC) Motors:alternating tam sim no tuaj yeem tau txais los ntawm lub qhov hluav taws xob ntawm phab ntsa. AC motors siv cov khoom siv hluav taws xob ntau los tsim hluav taws xob induction. Engineers nyiam AC mechanisms thaum yuav tsum tau ceev ceev. Txawm li cas los xij, lawv tsis tshua muaj sab nraud ntawm kev lag luam-scale, high-torque robots.
- Direct Current (DC) Motors:Es tsis txhob siv lub qhov hluav taws xob phab ntsa, DC motors feem ntau kos lub zog ntawm lub roj teeb. DC mechanisms tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab muaj qhov sib txawv ntawm qhov sib txawv, nrog rau lub sij hawm teb ceev thiab maneuverability piv rau cov qauv plug-in.
- Servomotors:Kuj tseem hu ua "servos" thiab suav nrog kev lag luam servomotors, cov no yog qee qhov siab tshaj plaws precision motors muaj. Lawv txhawb yuav luag tam sim ntawd kev ua yuam kev hloov thaum lub sijhawm ua haujlwm. Cov motors no zoo tagnrho rau cov neeg hlau caj npab thiab lwm yam neeg hlau thiab sib koom ua ke cov neeg hlau yog tias koj xav tau qhov tseeb qhov chaw thiab siab torque hauv ib pob me me. Thaum siv servos, tej zaum yuav muaj kev ncua ntawm kev txav.
- Stepper motors:Stepper motors khiav nyob rau hauv me me increments muab siab torque thaum tuav ib yam khoom nyob ruaj ruaj - thiab meej positioning ntawm txhua kauj ruam. Qhov tseeb ntawm cov motors no feem ntau nyob ntawm qhov kev txiav txim ntawm 0.01 degrees thiab 0.1 millimeters. Zuag qhia tag nrho torque zoo ib yam li cov servo lub cev muaj zog. Stepper motors yog kim dua los khiav dua lwm hom raws li lub zog xav tau.
Yuav ua li cas xaiv lub cev muaj zog rau koj tus neeg hlau?
Koj tuaj yeem tshawb xyuas cov ntsiab lus saum toj no kom txo qis cov motors koj xaiv rau koj qhov project robotics tom ntej. Txawm li cas los xij, ua ntej koj rov nyeem tag nrho lawv, tsim ib daim ntawv teev npe tsis tuaj yeem nco cov yam ntxwv uas koj cov neeg hlau xav tau.
Nws yuav ua haujlwm li cas thiab koj qhov kev ua yuam kev yog dab tsi rau nws txoj kev txav?
Txheeb xyuas qhov kev tswj hwm ib puag ncig kom nkag siab koj qhov kev zam rau kev sib kis. Tsis tsuas yog lub cev muaj zog kis tau tus mob loj ua rau lub cev muaj zog tsis ua haujlwm, tab sis nws tseem yog ib qho kev hem thawj rau cov khoom lag luam zoo nyob rau hauv ib puag ncig kev pheej hmoo-averse manufacturing.
Hauv lwm lo lus, koj yuav tsis tas yuav tsum phim lub tshuab hluav taws xob hydraulic nrog lub tshuab ua haujlwm siab, ua kom huv huv zoo xws li khoom noj lossis tshuaj tsim khoom.
Nov yog lwm cov ntsiab lus los nrhiav thaum koj tshawb fawb ntau hom neeg hlau tshuab:
- Loj-rau-lub zog piv:qhov loj ntawm koj lub tsev yog dab tsi? Puas yog tus neeg hlau yuav tsum taug kev los ntawm qhov chaw nruj, lossis puas yog lub zog raw tseem ceeb dua qhov loj?
- Load txwv:Hom tsav koj xaiv rau koj cov neeg hlau xav tau txaus torque los lis cov kev cia siab uas nws yuav nqa.
- Qhov tseeb:Dab tsi yog qhov kam rau qhov txawv txav thaum tus neeg hlau txav? Koj puas xav tau lub cev muaj zog uas muab kev kho qhov yuam kev tam sim thiab raug?
- Kev ntseeg tau:Cov neeg ua haujlwm zoo npaum li cas yog koj lub tuam tsev kho mob? Ntev npaum li cas koj cia siab tias koj tus neeg hlau yuav tau txais kev pabcuam?
- Kev siv peev txheej:Tsis yog txhua tus neeg hlau lub cev muaj zog yog ib puag ncig zoo ib yam li lwm tus. Stepper motors siv lub zog txawm tias nyob rau hauv hom standby, tab sis qee zaum lawv yog tib txoj kev xaiv.
Motors rau txhua tus neeg hlau
Motors khiav lub gamut los ntawm cov neeg siv khoom mus rau loj-scale robotics deployments. Yog tias koj tshawb fawb txog kev tswj hwm thiab chaw ua haujlwm ib puag ncig ua ntej, koj yuav paub sai sai tias txhua qhov kev pabcuam neeg hlau muaj lub cev muaj zog.
