Lub "locomotion genes" ntawm ib tug neeg hlau mobile nyob sib sib zog nqus nyob rau hauv nws chassis architecture-txawm yog threading los ntawm khib- tuab warehouse aisles los yog trudging hla av nkos, rugged qhib- qhov chaw, qhov kev xaiv ntawm chassis tsav qauv ncaj qha txhais cov neeg hlau lub hnab ntawv. Los ntawm qhov minimalism ntawm ob-log tsav sib txawv mus rau qhov tseeb tswj ntawm AGV tsav lub log, los ntawm cov teeb meem brute - kov yeej lub hwj chim ntawm txoj kev mus rau qhov zoo nkauj txhais ntawm omnidirectional log, txhua hom chassis qhia txog kev sib haum xeeb ntawm kev tsim kho tshuab, tswj algorithms, thiab qhov yuav tsum tau ua. Anchored nyob rau hauv cov ntsiab cai ntawm kev txawj ntse thiab illustrated nrog kev lag luam cov ntaub ntawv kev tshawb fawb, kab lus no systematically lov tes taw cov yam ntxwv ntawm kev ua tau zoo thiab adaptation logic ntawm mainstream chassis architectures, muab kev txiav txim siab- makers thiab developers nrog ib tug meej siv.
I. Ob-Wheel Differential Chassis: Lub Bedrock ntawm Tsawg-Nyob Hauv Tsev Navigation
Ob tus qauv - log sib txawv nyob ntawm kev tswj ceev ceev ntawm sab laug thiab sab xis. Siv cov kev sib npaug sib txawv
(v=VL+VR2v=2VL+VR, ω=VR−VLlω=lVR-VL)
nws ua tiav lub kauj tsheb yam tsis muaj kev tswj xyuas lub tshuab ua haujlwm. Nws cov qauv yooj yim thiab tus nqi qis ua rau nws mus - rau cov neeg hlau hauv tsev. Piv txwv li, Ecovacs DEEBOT X2 lub tshuab nqus tsev vacuum ntiav ob-log tsav sib txawv ntxiv rau lub log tsis muaj zog, tso cai rau hloov pauv hloov pauv hauv qhov chaw qis li 8 cm. Txawm li cas los xij, nws nyob rau hauv -txoj kev txwv (tsis muaj kev txav mus los) cuam tshuam txoj kev npaj, thiab odometry drift yuav tsum tau them nyiaj los ntawm LiDAR-SLAM lossis pom kev-inertial fusion. Kev nce qib tsis ntev los no-xws li dynamic torque distribution algorithms thiab optimized unsprung-mass designs-ua tau zoo heev los tiv thaiv-slip kev ua tau zoo ntawm cov pobzeb lossis cov ntaub pua plag.
II. Plaub -Wheel Differential Chassis: "Mechanical Beast" rau Rough Terrain
Ib tug plaub-log ywj siab- tsav qauv siv faib lub cev muaj zog tswj kom ua tau raws li qhov kev hloov pauv hauv av. Siv Clearpath Robotics 'Husky unmanned hauv av tsheb: txhua lub hub nqa lub tshuab hluav taws xob muaj peev xwm ntawm 1,200 Nm ncov torque, ua ke nrog lub hauv paus sib txawv ntawm qhov sib txawv thiab kho ncua kev ncua kom nce 40℃qhov siab thiab hla 25 cm trenches. Txij li thaum lub kauj yog ua tiav los ntawm qhov sib txawv ntawm lub log nrawm (tsis muaj kev sib txuas ntawm lub kauj tsheb), cov khoom siv hluav taws xob raug txo qis -tab sis kev tswj cov txheej txheem yuav tsum daws plaub lub log nrawm thiab lub kauj tsheb kinematics hauv lub sijhawm tiag tiag kom tsis txhob plam -kev ua yuam kev trajectory. Hauv kev ua liaj ua teb, John Deere lub tsheb laij teb autonomous leverages plaub -log tsav sib txawv nrog RTK GNSS txoj hauj lwm kom ua tiav centimeter- qib raug ntawm cov kab qoob loo.
III. Ackermann Chassis: Tus "Tsev Tsim Kho Tshiab" rau siab -Speed Scenario
Raws li cov qauv kev tsav tsheb kauj vab geometry, Ackermann qauv siv lub log sab hauv loj dua - lub log lub kaum sab xis dua li lub log sab nraud kom txo qis rau sab nraub qaum, nrog lub nraub qaum - lub log tsav xa cov propulsion du. TuSimple tus kheej - tsav tsheb thauj khoom tau txais kev kho Ackermann geometry kom ua tiav 15 m tig vojvoog ntawm 80 km / h. Tsis ntev los no evolutions-steer-los ntawm-hlau (SBW) integrated nrog rear-wheel active steering (RWS)-yog qhov tseem ceeb: Mercedes-Benz eActros tsheb thauj khoom siv 5℃rear steering lub kaum sab xis los txo qis 20% txoj kab uas hla loading -dock maneuvers. Txawm li cas los xij, zoo li txhua yam tsis yog -holonomic systems, qhov tseeb txhais lus sab nraud tseem tsis muaj thiab yuav tsum tau hais nyob rau hauv siab dua - theem kev npaj.
IV. Mecanum-Wheel Chassis: "Omni-Dab" ntawm Tight Spaces
Los ntawm mounting 45℃rollers nyob ib ncig ntawm txhua lub log, Mecanum chassis ua tiav tag nrho cov phiaj xwm omnidirectional motion-txhua lub log yuav tsum tig mus rau pem hauv ntej lossis rov qab hauv cov qauv ua ke. KUKA's OmniMove AGV siv qhov no los nqa ntau-tuj dav hlau qhov chaw thiab tso lawv nrog 0.1 hli precision hauv cov rooj sib txoos. Txawm li cas los xij, cov menyuam hnav yog qhov teeb meem tseem ceeb: tom qab 2,000 h ntawm kev ua haujlwm tas mus li, qhov kev ua haujlwm tsis raug tuaj yeem tshaj 3 hli, xav tau kev ntsuas tsis tu ncua thiab kev sib txhuam hauv online -coefficient kwv yees.
V. Omnidirectional-Wheel Chassis: "Plua plav-Dawb Dancer" hauv Precision Settings
Muaj tseeb omnidirectional log mount rollers perpendicular rau lub log hub, tag nrho decoupling X / Y motion. Nikon's semiconductor-cov khoom siv hauv tsev- tuav cov neeg hlau siv peb lub- lub log, 120℃layout hauv chav huv huv los ua kev vibration- dawb sab txhais lus uas tiv thaiv wafers. Muab piv rau Mecanum, lub peev xwm them tau qis dua (feem ntau <500 kg) tab sis hauv av -flatness kam rau ua siab dua. Nyob rau theem tswj, thim rov qab-kinematics matrices yuav tsum tau daws los ua ke kom meej lub log-ceev vectors, muab cov kev xav tau siab ntawm onboard suav.
VI. AGV Tsav-Wheel Chassis: "Tag nrho-Round Performer" hauv Industrial Logistics
Lub AGV tsav lub log sib koom ua ke tsav thiab lub kauj rau hauv ib qho qauv, tso cai rau txhua lub log lub kaum sab xis thiab ceev kom tswj tau nws tus kheej rau holonomic motion:
Plaub AGV tsav log: Siasun's HCR series txhawb xoom- vojvoog tig thiab lateral drifting, zoo tagnrho rau siab - kab dynamic- sab xa hauv tsheb cov nroj tsuag.
Dual AGV tsav log: Geek+'s P800 neeg hlau ua tiav 10 cm qhov tseeb qhov tseeb hauv 3.5 m- txoj kab dav dav, ntawm 40% tus nqi qis dua plaub- lub log.
Ib leeg AGV tsav log: Hikvision's MV series counterbalanced forklift siv "crank-link" tsim los tswj kev sib tw ntawm cov plag tsev tsis sib xws.
Cov qauv tam sim no tsom mus rau ultra-slim thiab siab- lub zog- ntom nti modules-piv txwv li, Jiateng's V- zoo li tus tsav log tsuas yog 85 hli tuab tsis tau ua haujlwm 1.2 t loads.
VII. Taug qab Chassis: Tus "Survival Expert" rau qhov chaw siab heev
Hlau los yog roj hmab lem kis hauv av siab tshaj qhov chaw loj, zoo heev hauv swamps, daus, thiab xuab zeb. Russia's Uran-6 demining neeg hlau siv txoj kev hloov kho tau-tensioner kom hloov mus rau pob zeb lossis av nkos, khaws cov nqi qis dua 5%. Txawm li cas los xij, cov kauj ruam taug qab siv peb lub zog ntau dua li ncaj nraim - txoj kab txav, thiab sab hauv av hauv av yuav raug puas tsuaj. Hybrid chassis (khiav + lub log) muab kev sib haum xeeb: Tuam Tshoj Electronics Technology Group's "Qilin" neeg hlau hloov ntawm hydraulics ntawm txoj kev loj thiab kev tawm tsam kev cuam tshuam.
Xaus
Los ntawm qhov yooj yim ntawm ob- lub log sib txawv mus rau qhov tseeb ntawm ntau-AGV tsav- lub log holonomics, mobile- neeg hlau chassis tau hloov mus rau hauv lub cev txawj ntse fusing mechanics, electronics, thiab AI. Cov neeg tsim khoom yuav tsum tshaj qhov tshwj xeeb thiab txiav txim siab los ntawm qhov xwm txheej: seb qhov xav tau yog millimeter-theem lateral precision lossis kilometer-scale endurance; rugged impact resistance los yog siab tshaj spatial efficiency. Tsuas yog los ntawm kev sib piv chassis architecture mus rau kev ua haujlwm logic tuaj yeem ua rau tus neeg hlau muaj peev xwm ua kom tiav. Thiab thaum lub tswv yim "ib-chassis- haum-tag nrho" yuav tuaj txog nrog cov khoom siv yav tom ntej thiab tsav kev sib tw, niaj hnub kev txawj ntse xav paub txog txhua qhov kev daws teeb meem.
