Kev lag luam neeg hlau tactile sensor tuaj yeem pab cov neeg hlau muaj kev ntsuas txhua lub cev sib cuam tshuam nrog nws ib puag ncig. Lub sensor tuaj yeem ntsuas qhov tsis muaj feem cuam tshuam nrog kev sib cuag ntawm lub sensor thiab cov khoom. 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?
Lub tactile sensor yog tsim raws li nws cov kev nkag siab ntawm kev sib chwv, thiab tuaj yeem ntes cov stimulation ntawm txhua yam stimulation, kub thiab mob. Lub tactile sensor 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 sensors siv nyob rau hauv robots simulate tactile functions. Nws tuaj yeem muab faib ua kev sib cuag sensor, quab yuam-torque sensor, siab sensor thiab plam sensor raws li kev ua haujlwm.
Dab tsi yog tactile sensors?
1. Optical tactile sensor: Muaj ob hom optical tactile sensor: sab hauv thiab sab nraud. Nyob rau hauv hom no, qhov kev siv ntawm lub teeb yog modulated los ntawm kev txav obstacles rau hauv txoj kev kho qhov muag. Nws muaj qhov zoo ntawm kev tiv thaiv hluav taws xob cuam tshuam thiab muaj kev daws teeb meem siab heev. Kev xaim qis yog xav tau, thiab cov khoom siv hluav taws xob ua haujlwm tuaj yeem nyob deb ntawm lub sensor.
2. Piezoelectric tactile sensor: Thaum lub siab raug siv rau qhov ntsuas qhov ntsuas, qhov cuam tshuam ntawm kev tsim hluav taws xob ntawm qhov ntsuas qhov ntsuas yog cov nyhuv piezoelectric. Qhov tsim ntawm voltage yog proportional rau lub siab thov. Hauv qhov no, tsis tas yuav tsum muaj lub sensor sab nraud. Qhov zoo ntawm hom sensor no yog durability thiab dav dynamic ntau yam. Kev ntsuas siab yog ua tau.
3. Resistive tactile sensor: lub sensor ua haujlwm raws li kev hloov pauv ntawm kev ua haujlwm ntawm polymer thiab electrode. Hom tactile sensor no yog siv dav. Thaum siv lub siab, qhov kev tiv thaiv ntawm cov khoom siv hluav taws xob yuav hloov. Tom qab ntawd ntsuas qhov tsis kam. Qhov zoo ntawm no sensor yog siab durability thiab zoo overload kuj.
4. Capacitive tactile sensor: Nyob rau hauv capacitive sensor, lub capacitance hloov ntawm ob electrodes yog siv. Hom capacitive sensor no yuav ntsuas capacitance, uas yuav hloov pauv raws li kev siv siab. Lub capacitance ntawm parallel phaj capacitor muaj feem xyuam rau qhov sib nrug thiab cheeb tsam ntawm daim hlau. Capacitance 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 sensor: sib nqus tactile sensor siv ob txoj hauv kev, ib qho yog ntsuas qhov kev hloov pauv ntawm cov hlau nplaum sib nqus siv cov khoom siv magnetoresistive, thiab lwm qhov yog ntsuas qhov kev hloov pauv ntawm cov sib nqus coupling deformation ntawm windings ntawm magnetoelastic core. Qhov zoo ntawm no sensor yog siab rhiab heev thiab tsis muaj mechanical lag.
