Muaj cov neeg hlau tactile sensors tuaj yeem pab cov neeg hlau ua lag luam ntsuas txhua qhov kev cuam tshuam lub cev nrog lawv ib puag ncig, thiab qhov ntsuas ntsuas no tuaj yeem ntsuas qhov ntsuas tsis muaj feem cuam tshuam nrog kev sib cuag ntawm lub sensor thiab cov khoom. Thiab industrial robots kuj tau txais txiaj ntsig los ntawm kev kov. Force thiab tactile sensors pab neeg hlau los tswj cov khoom uas muaj qhov tseeb dua thiab rhiab heev hauv ib puag ncig uas muaj cov qauv tsawg dua.
Dab tsi yog tactile sensor?
Tactile sensors yog tsim los ntawm kev hnov mob ntawm lawv qhov kov thiab tuaj yeem ntes cov stimuli los ntawm cov neeg kho tshuab stimuli, kub, thiab mob. Tactile sensors yuav tau txais thiab teb rau cov teeb liab, uas tuaj yeem yog quab yuam lossis kev sib cuag ntawm lub cev. Tactile sensors yog cov sensors siv hauv cov neeg hlau los ua cov haujlwm tactile. Nws tuaj yeem muab faib ua kev sib cuag sensors, quab yuam torque sensors, siab sensors, thiab plam sensors raws li lawv txoj haujlwm.
Dab tsi yog tactile sensors?
1. Optical tactile sensors: Muaj ob hom optical tactile sensors, sab hauv thiab sab nraud, nyob rau hauv uas qhov kev siv ntawm lub teeb yog modulated los ntawm kev txav obstacles rau hauv txoj kev kho qhov muag. Nws muaj qhov zoo xws li tsis kam tiv thaiv electromagnetic cuam tshuam thiab muaj kev daws teeb meem siab heev. Yuav tsum muaj cov hlua hluav taws xob tsawg, thiab cov khoom siv hluav taws xob ua haujlwm tuaj yeem khaws cia deb ntawm cov sensors.
2. Piezoelectric tactile sensor: Cov nyhuv ntawm qhov tsim hluav taws xob ntawm qhov ntsuas qhov ntsuas thaum lub siab siv yog hu ua cov nyhuv piezoelectric. Qhov tsim ntawm voltage yog proportional rau lub siab thov. Hauv qhov no, tsis tas yuav tsum muaj cov sensors sab nraud. Qhov zoo ntawm hom sensor no yog durability thiab dav dynamic ntau yam. Kev ntsuas siab tuaj yeem ua tau.
3. Resistive tactile sensor: Lub sensor ua haujlwm raws li qhov kev hloov pauv ntawm cov khoom siv hluav taws xob thiab cov electrode. Hom tactile sensor no yog siv dav. Thaum lub siab yog thov, qhov tsis kam ntawm cov ntaub ntawv conductive hloov. Tom qab ntawd ntsuas qhov tsis kam. Qhov zoo ntawm no sensor yog siab durability thiab zoo overload kuj.
4. Capacitive tactile sensor: Hauv capacitive sensors, capacitance hloov ntawm ob electrodes yog siv. Hom capacitive sensor no yuav ntsuas capacitance, uas yuav hloov pauv raws li qhov kev thov siab. Lub capacitance ntawm parallel phaj capacitors muaj feem xyuam rau qhov sib nrug thiab cheeb tsam ntawm daim hlau. Lub capacitance yuav txawv raws li lub load. Qhov zoo ntawm cov sensor no yog cov lus teb linear thiab dav dynamic ntau yam.
5. Sib nqus tactile sensors: Sib nqus tactile sensors siv ob txoj hauv kev: ib qho yog ntsuas kev hloov pauv hauv cov hlau nplaum sib nqus siv cov khoom siv magnetoresistive, thiab lwm qhov yog ntsuas kev hloov pauv hauv kev sib nqus sib nqus deformation ntawm windings ntawm magnetoelastic cores. Qhov kom zoo dua ntawm no sensor yog nws siab rhiab heev thiab tsis muaj mechanical lag.
Lub luag haujlwm ntawm Industrial Robot Tactile Sensors
Hauv kev lag luam neeg hlau ua haujlwm thev naus laus zis, ib yam li hauv tib neeg kev ua haujlwm, kev pom thiab kov yog cov qauv ua ke. Cov kws tshaj lij hauv kev lag luam kwv yees tias kev hnov mob yuav sai sai no suav nrog cov cuab yeej pom kev rau hauv cov ntawv thov neeg hlau tseem ceeb. Yeej, muaj cov neeg hlau tactile sensors yog ib hom kev kov sensor uas tuaj yeem muab cov ntaub ntawv hais txog cov khoom hauv kev sib cuag nrog lawv. Cov ntaub ntawv xa tawm yog hais txog cov duab, qhov loj me, thiab hom ntawm cov khoom raug kov.
Muaj cov neeg hlau tactile sensors tuaj yeem ntes qee yam, xws li muaj cov khoom. Nws tseem tuaj yeem txiav txim siab qhov zoo li, txoj haujlwm, thiab kev taw qhia ntawm ntu. Cov khoom nyob rau hauv kev sib cuag nrog lub sensor yog lub siab, yog li ntawd lub siab tis tau txiav txim. Nrog kev pab los ntawm cov cuab yeej no, cov khoom tuaj yeem raug tshuaj xyuas, xws li kev soj ntsuam kev ntxhib los mos, kev tshuaj xyuas sib koom ua ke, lossis kev puas tsuaj. Muaj neeg hlau tactile sensors tuaj yeem ntes ntau yam stimuli, kuaj pom cov khoom, thiab tau txais cov duab tactile. Tactile sensors muaj ntau qhov chaw rhiab, thiab nrog kev pab los ntawm cov khoom no, lawv tuaj yeem ntsuas ntau yam cwj pwm.
Lub luag haujlwm tseem ceeb ntawm kev lag luam neeg hlau tactile sensor suav nrog lub microswitch, uas yog qhov hloov pauv mus rau ntau yam ntawm cov lus tsa suab. Nws yog array ntawm kov sensors, tsim ib tug loj sensor hu ua tactile sensor. Ib qho tshwj xeeb kov sensor yuav piav qhia txog kev sib cuag ntawm lub cev ntawm tus neeg hlau tus ntiv tes thiab qhov chaw zoo nkauj. Thaum cov neeg hlau muaj kev sib cuag nrog ib qho khoom, nws xa cov teeb liab mus rau tus tswj.
