Muaj neeg hlau tactile sensorstuaj yeem pab cov neeg hlau ua lag luam ntsuas kev cuam tshuam lub cev nrog lawv ib puag ncig. Sensors tuaj yeem ntsuas qhov tsis sib xws ntawm kev sib cuag ntawm cov sensors thiab cov khoom. Industrial robots kuj tau txais txiaj ntsig los ntawm kev kov. Force thiab tactile sensors ua rau cov neeg hlau los tswj cov khoom nrog qhov raug siab dua thiab rhiab heev hauv qhov chaw me me.
Tactile sensors yog tsim los ntawm kev hnov mob ntawm lawv qhov kov thiab tuaj yeem ntes cov neeg kho tshuab stimuli, stimulation kub, thiab mob. Tactile sensors yuav tau txais thiab teb rau cov teeb liab ntawm kev quab yuam lossis kev sib cuag ntawm lub cev.
Muaj ntau ntau yam sib txawv tactile sensors nyob rau hauv ib tug series ntawm daim ntaub ntawv, xws li sensing ib txwm siab thiab dynamic tactile sensing. Lawv yog ib qho ntawm feem ntau siv sensors hauvrobotics technology, suav nrog piezoelectric, resistive, capacitive, thiab elastic hom. Kab lus no yuav qhia txog cov haujlwm thiab hom tactile sensors rau cov neeg hlau muaj.
1. Optical tactile sensors: Muaj ob hom optical tactile sensors: sab hauv thiab sab nraud. Nyob rau hauv hom no, qhov kev siv ntawm lub teeb yog kho los ntawm kev txav obstacles mus rau lub teeb txoj kev. Nws muaj qhov zoo ntawm kev tiv thaiv electromagnetic cuam tshuam thiab kev daws teeb meem siab. Kev xaim qis yog xav tau, thiab cov khoom siv hluav taws xob tuaj yeem khaws cia deb ntawm cov sensors.
2. Piezoelectric tactile sensor: Thaum lub siab yog siv rau lub sensor caij, qhov voltage nyhuv ntawm lub sensor lub caij hu ua piezoelectric nyhuv. Lub cim ntawm voltage yog ncaj qha proportional rau lub siab thov. Hauv qhov no, tsis tas yuav tsum muaj cov sensors sab nraud. Qhov zoo ntawm no sensor yog durability thiab dav dynamic ntau yam. Nws tuaj yeem ntsuas qhov siab.
3. Resistance tactile sensor: Lubkev ua haujlwm sensoryog raws li qhov kev hloov pauv ntawm kev ua haujlwm ntawm cov conductive polymer thiab 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 no sensor muaj qhov zoo xws li siab durability thiab zoo overload kuj.
4. Capacitive tactile sensor: Lub capacitance hloov ntawm ob lub electrodes yog siv rau capacitive sensors. Hom capacitive sensor no yuav ntsuas capacitance thiab hloov pauv raws li kev siv siab. Lub capacitance ntawm parallel phaj capacitors muaj feem xyuam rau qhov sib nrug thiab cheeb tsam ntawm daim hlau. Capacitors yuav txawv raws li qhov load. Qhov no sensor muaj qhov zoo ntawm 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, thiab lwm qhov yog ntsuas kev hloov pauv hauv kev sib nqus sib nqus deformation ntawm windings. Qhov no sensor muaj qhov zoo ntawm siab rhiab heev thiab tsis muaj mechanical lag.
Lub luag haujlwm ntawm kev lag luam neeg hlau tactile sensors
In industrial robots ua haujlwm technology, lub zeem muag thiab kov yog hom kev sib txuas ntxiv, ib yam li hauv tib neeg. Cov kws tshaj lij kev lag luam kwv yees tias kev siv tshuab pom sai sai yuav raug ntxiv rau cov ntawv thov neeg hlau tseem ceeb. Yeej, muaj neeg hlau tactile sensors yog kov sensors uas tuaj yeem muab cov ntaub ntawv ntsig txog cov khoom uas lawv tau ntsib. Cov ntaub ntawv yog hais txog cov duab, qhov loj me, thiab hom ntawm cov khoom kov.
Kev lag luam neeg hlau tactile sensors tuaj yeem kuaj pom cov khoom thiab lwm yam khoom. Nws kuj tseem tuaj yeem txiav txim siab cov duab, txoj haujlwm, thiab kev coj ntawm cov khoom. Kev sib cuag nrog cov khoom nyob rau hauv kev sib cuag nrog lub sensor yog siab, yog li ntawd lub siab tis tau txiav txim. Cov cuab yeej no tuaj yeem ua qhov kev tshuaj xyuas ntawm cov khoom, 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 yam rhiab heev. Nrog kev pab los ntawm cov khoom no, tactile sensors tuaj yeem ntsuas ntau yam cwj pwm.
Cov khoom siv ua haujlwm ntawm kev lag luam neeg hlau tactile sensors suav nrog micro hloov uas nkag siab rau ntau yam ntawm cov lus tsa suab. Nws yog ib tug kov sensor array uas tsim ib tug loj sensor hu ua ib tug kov 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 ntxhib los mos. Thaum tus neeg hlau muaj kev sib cuag nrog ib qho khoom, nws yuav xa cov teeb liab mus rau tus maub los.
Kab lus no feem ntau qhia txog kev ua haujlwm thiab hom tactile sensors rauindustrial robots. Los ntawm kev txheeb xyuas tag nrho cov ntawv nyeem, nws tuaj yeem nkag siab tias kev pom thiab kov yog cov qauv sib txuas hauv tib neeg lub luag haujlwm ntawm kev lag luam tshuab ua haujlwm tshuab. Cov kws tshaj lij kev lag luam kwv yees tias cov sensors kov yuav sai sai ntxiv cov cuab yeej pom kev rau cov ntawv thov neeg hlau tseem ceeb. Yeej, muaj neeg hlau tactile sensors yog ib hom kev kov sensor uas tuaj yeem muab cov ntaub ntawv ntsig txog cov khoom hauv kev sib cuag. Cov ntaub ntawv xa mus yog hais txog cov duab, qhov loj me, thiab hom ntawm cov khoom kov.
