Motors li Core Hardware Tsav Neeg Hlau Movement

Raws li lub hauv paus ntawm kev tsav tsheb torque, lub cev muaj zog yog qhov tseem ceeb hauv kev siv cov neeg hlau pob qij txha. Lub cev muaj zog, feem ntau hu ua "lub cev muaj zog," yog ib yam khoom uas hloov los yog xa hluav taws xob raws li txoj cai ntawm electromagnetic induction, sawv cev los ntawm tsab ntawv "M" hauv circuits. Nws lub luag haujlwm tseem ceeb yog tsim kom muaj lub zog tsav tsheb, muab lub zog rau ntau yam khoom siv hluav taws xob thiab cov cuab yeej siv tshuab.

 

Hauv kev ua haujlwm ntawm robotics, kev sib koom ua ke yog ib qho tseem ceeb rau kev ua tiav ntau yam kev txav, nrog rau kev sib koom ua ke ntawm cov motors suav tias yog chav ua haujlwm ntawm tag nrho cov system. Ib qho kev sib koom ua tiav neeg hlau feem ntau suav nrog tus tsav tsheb, tus tswj hwm, thiab lub cev sib koom ua ke. Kev sib koom ua ke lub cev muaj zog tsis yog tsuas yog yuav tsum tau ua cov haujlwm xws li txo qhov nrawm, xa tawm, thiab txhim kho torque, tab sis kuj yuav tsum tswj cov kev sib koom ua ke nrog kev ua haujlwm siab.

 

Cov neeg hlau sib koom ua ke ncaj qha cuam tshuam rau kev ua haujlwm nyuaj xws li taug kev, khiav, thiab dhia. Nws yog lub npe hu ua "lub plawv" ntawm tus neeg hlau, thiab nws qhov kev ua tau zoo ua lub luag haujlwm txiav txim siab hauv cov neeg hlau qhov tseeb thiab kev ua haujlwm zoo.
