Sidee loo Hubiyaa Saxnaanta Robot-yada Shan-dhidibka ah ee Servo?

Sidee loo Hubiyaa Saxnaanta Robot-yada Shan-Axis Servo? Laga bilaabo Tiknoolajiyadda Aasaasiga ah ilaa Hirgelinta

Soo saarista saxda ah, isu-imaatinka elektaroonigga ah, habaynta qalabka caafimaadka, iyo meelaha kale, saxnaanta robotyada servo ee shan-dhidib leh ayaa si toos ah u go'aamisa tayada wax soo saarka iyo hufnaanta wax soo saarka. Marka la barbardhigo saddex-dhidib.Robot-yada Axis-ka,nidaamyada shan-dhidibka, oo leh laba faasas oo wareeg ah oo dheeraad ah (badanaa faasasyada A, C, ama B), waxay gaari karaan dhaqdhaqaaq meeleed oo aad u adag, laakiin tani waxay sidoo kale keenaysaa baahiyo sare oo ku saabsan xakamaynta saxda ah - xitaa qaladka 0.01mm wuxuu keeni karaa qayb ka mid ah qashinka iyo joojinta khadadka wax soo saarka. Maqaalkani wuxuu falanqeyn doonaa hababka muhiimka ah ee lagu hubinayo saxnaanta robotyada shan-dhidib leh ee servo laga bilaabo shan dhinac oo asaasi ah: naqshad farsamo, nidaamka servo, algorithm-ka xakamaynta, rakibidda iyo u-gudbinta, iyo dayactirka joogtada ah, iyadoo bixinaysa hage wax ku ool ah oo loogu talagalay xulashada iyo hawlgalka shirkadda.

Marka hore. Qaab-dhismeedka Farsamada: "Aasaaska Jirka" ee Saxnaanta: Xakamaynta Khaladaadka laga bilaabo Isha Naqshadeynta

Saxnaanta robot-ka shan-dhidiblaha ah ee servo waxay inta badan ku xiran tahay xasilloonida qaab-dhismeedkiisa farsamada. Isbeddel kasta, ciyaar, ama xirasho kasta oo ka mid ah qaybihiisa waxay si toos ah u horseedi doontaa khaladaad dhaqdhaqaaq. Diiradda saar saddexda qaybood ee muhiimka ah ee soo socda:

1. Qaybaha Gudbinta Aasaasiga ah: Doorashada Nooca Saxda ah iyo Xakamaynta Saxnaanta
Nidaamka gudbinta ayaa fure u ah gudbinta korontada iyo fulinta saxda ah labadaba. Hababka gudbinta caadiga ah waxaa ka mid ah boolal kubbadda, kuwa yareeya iswaafajinta, iyo kuwa yareeya meeraha. Kuwaas waa in la waafajiyaa iyadoo lagu saleynayo shuruudaha culeyska iyo saxnaanta:

Boolal kubbadeed: Kuwani waxay mas'uul ka yihiin dhaqdhaqaaqa faasasyada toosan (sida faasasyada X/Y/Z). Saxnimadoodu waxay si toos ah u saamaysaa khaladka meelaynta. Waxaan kugula talineynaa inaad doorato saxnaanta C3 ama ka sareeya (qaladka meelaynta ≤ 0.008mm/300mm). Waa in la isticmaalaa farsamo hore loo raro (sida preload double-lowt) si loo baabi'iyo dib-u-dhaca u dhexeeya boolal iyo lowska. Birta dahaarka leh ee xoogga badan (sida SUJ2) waa in la doorbidaa, oo la adkeeyaa (adagaanshaha dusha sare ≥ HRC58) si loo yareeyo xirashada iyo isbeddelka ka dib isticmaalka muddada dheer.

Dhimista Harmonic-ka: Waxaa loo isticmaalaa faasas wareegaya (sida faasasyada A/C), waxay bixiyaan faa'iidooyin sida saamiga gudbinta sare iyo cabbirka is haysta. Si kastaba ha ahaatee, isbeddelka laastikada ee flexspline wuxuu sababi karaa khaladaad soo laabasho. Dooro qaab sax ah oo sare leh oo leh qalad soo celin ah ≤1 daqiiqo arc. Sidoo kale, xakamee xawaaraha gelinta (ka fogow inaad dhaafto 80% xawaaraha la qiimeeyay) si loo yareeyo dhaawaca daalka ee flexspline-ka. Qaar ka mid ah qalabka heerka sare ah waxay isticmaalaan isku-darka hoos u dhigista harmonic-ka iyo cod-bixiyaha buuxa si loo magdhabo khaladaadka isbeddelka laastikada waqtiga dhabta ah.

Tilmaamaha: Kuwani waxay hagayaan dhaqdhaqaaqa robot-ka waana inay ilaaliyaan isbarbardhigga qaybaha gudbinta. Tilmaamaha duubista toosan ayaa lagu talinayaa (waxay bixiyaan awood culays iyo adkaansho ka badan hagaha kubadda). Inta lagu jiro rakibidda, hagaaji isbarbardhigga tareenka hagaha adoo isticmaalaya qalabka laysarka (qalad ≤0.005mm/m) si looga fogaado "guuritaanka" ama iswaafajinta khaldan ee ka dhalata janjeedhka tareenka hagaha.

2. Qaab-dhismeedka: Isku dheelitirka u dhexeeya adkaanta iyo miisaanka fudud

Adkaanta qaab-dhismeedka oo aan ku filnayn waxay horseedi kartaa "isbeddel gariir" inta lagu jiro dhaqdhaqaaqa, gaar ahaan xawaaraha sare ama culaysyo culus, halkaas oo khaladaadka la weyneeyo. Tixgelinta naqshadeynta:

Xulashada agabka: Daloolada aluminiumka ee xoogga badan (sida 6061-T6) waxaa loo isticmaali karaa qalabka yar yar iyo kuwa dhexdhexaadka ah ee wax lagu beddelo, iyagoo isku dheelitiraya miisaanka iyo adkaanta. Isticmaalka culus (culeys ka badan 50kg), birta la shubay (sida HT300) ama qaab-dhismeedka birta la alxamay ayaa lagu talinayaa. Daaweynta gabowga waxaa loo isticmaali karaa in lagu baabi'iyo walbahaarka gudaha iyo in la yareeyo isbeddelka ka dib isticmaalka muddada dheer.

Hagaajinta qaab-dhismeedka: Qaado naqshad "taageero saddex-xagal ah" ama "nooca sanduuqa" si kor loogu qaado adkaanta qallooca ee qaab-dhismeedka. Ku dar feeraha xoojinta meelaha muhiimka ah ee culeyska qaada (sida isku xirka dhidibka wareegaya) si looga fogaado fiirsashada cadaadiska maxalliga ah. Tusaale ahaan, manipulator shan-dhidib ah oo ka socda soo saaraha qaybaha baabuurta ayaa yareeyay qaladka dhaqdhaqaaqa firfircoon 40% isagoo kordhinaya adkaanta qallooca ee qaab-dhismeedka laga bilaabo 150 N·m/° ilaa 280 N·m/°.

3. Wax-soo-saarka dhammaadka: La qabso culayska oo yaree "dhammaadka hoos u dhaca"

Miisaanka iyo saxnaanta rakibidda ee wax-qabadka dhammaadka (sida qabashada ama koobka nuugista) waxay saameyn doontaa "saxnaanta booska dhammaadka" ee qalabka wax-qabadka. Mabda'a "iswaafajinta culayska" waa in la raaco:

Culayska ugu dambeeya waa inaanu dhaafin 80% culayska la qiimeeyay ee robot-ka (si looga fogaado isbeddelka usha oo ay keento culayska xad-dhaafka ah);

Xidhiidhka u dhexeeya hawl-wadeenka iyo flange-ka robot-ka waa in lagu xidhaa biinanka dowel-ka iyo boolal xoog badan leh. Khaladka fidsan ee dusha flange-ka waa inuu ahaadaa ≤ 0.003mm, khaladka isku-xidhkana waa inuu ahaadaa ≤ 0.005mm si looga hortago khaladka dhammaadka oo ay ugu wacan tahay isku-xidhka oo aan sinnayn.

Marka labaad. Nidaamka Adeegga: "Awoodda Xudunta" ee Saxnaanta, Yaraynta Kala Duwanaanta Heerka Xakamaynta

Saxnaanta dhaqdhaqaaqa ee robot-ka shan-dhidib leh ee servo waa "awoodda nidaamka servo uu u leeyahay inuu raaco amarrada" - ka dib marka amar la diro, matoorka servo, darawalka, iyo encoder-ku waa inay wada shaqeeyaan si loo yareeyo khaladaadka. Saddexda dhinac ee soo socda waxay u baahan yihiin hagaajinta muhiimka ah:

1. Servo Motor: Xullo Nooca Saxda ah + Hagaajinta Xallinta

Matoorka servo waa "isha soo saarista korontada," saxnaantiisuna waxay si toos ah u go'aamisaa simanaanta dhaqdhaqaaqa iyo saxnaanta booska.

Xulashada Nooca: Matoorada servo ee joogtada ah ee magnet synchronous ayaa la door bidaa (waxay bixiyaan xawaare jawaab celin ah oo 30% ka dhakhso badan iyo 20% ka yar gariirka wareegga marka loo eego matoorada aan isku mid ahayn). Tani waxay si gaar ah muhiim ugu tahay xaaladaha joojinta-xawaaraha sare (sida qaadista qaybaha elektaroonigga ah), maadaama ay yareyn karaan khaladaadka "tallaabooyinka lumay" ee ay keento wareegga aan ku filnayn.

Xallinta Encoder-ka: Encoder-ku waa "qaybta jawaab celinta booska." Inta uu xallintu sarreyso, ayaa sii saxnaanaysa ogaanshaha booska. Waxaa lagu talinayaa in la isticmaalo encoder dhammaystiran oo 23-bit ah (saxnaanta booska ≤ 0.001mm) loogu talagalay dhidibyada toosan iyo encoder dhammaystiran oo 17-bit ah (saxnaanta xagasha ≤ 0.005°) loogu talagalay dhidibyada wareega. Marka la barbardhigo encoder-yada sii kordhaya, encoder-yada dhammaystiran uma baahna "hagaajinta guriga," taas oo ka hortagi karta leexashada booska ka dib marka korontada ay cillado oo dib u bilaabato.

2. Darawalka: Hagaaji algorithm-ka xakamaynta si loo yareeyo khaladaadka soo socda

Darawalka servo waa "xarunta xakamaynta matoorka," tayada algorithm-keeduna si toos ah ayuu u saameeyaa awooddiisa magdhowga khaladaadka. Hawlaha asaasiga ah ee soo socda waa in la hawlgeliyaa:
Is-hagaajinta otomaatiga ah ee halbeegga PID: Darawalku si toos ah ayuu u aqoonsadaa culeyska matoorka iyo firfircoonida, isagoo hagaajinaya xuduudaha saamiga (P), isku-dhafka (I), iyo kala duwanaanshaha (D) si loo yareeyo xad-dhaafka (tusaale ahaan, gariirka inta lagu jiro booska). Tusaale ahaan, macaamiil ku jira warshadaha 3C ayaa yareeyay dhidibka X ka dib qalad laga bilaabo 0.02mm ilaa 0.008mm iyada oo loo marayo hagaajinta otomaatiga ah ee darawalka.
Xakamaynta sii-haynta-dheer: Tani waxay saadaalinaysaa isbeddellada culeyska matoorka (tusaale ahaan, xoogga aan la saarin inta lagu jiro dardargelinta) ka hor waxayna si firfircoon u soo saartaa magdhowga wareegga si looga fogaado leexashada xawaaraha oo ay keento isbeddellada culayska. Xaaladaha isku xirka shan-dhidiblaha ah (tusaale ahaan, mashiinka dusha sare), xakamaynta sii-haynta-dheer waxay yareyn kartaa khaladaadka qaab-dhismeedka in ka badan 30%.
Xakamaynta resonance-ka: Si wax looga qabto resonance-ka farsamada inta lagu jiro Robot Mkuleyliyaha (tusaale ahaan, gariirka jir-dhiska inta lagu jiro dhaqdhaqaaqa xawaaraha sare), darawalku wuxuu adeegsadaa "shaandhaynta heerka" si uu u baabi'iyo gariirka mawjadaha gaarka ah, taasoo yaraynaysa saxnaanta ka-dhaafitaanka ay keento resonance-ka.

3. Xakamaynta Isku-dubaridka Shan-dhidiblaha ah: Xalinta "Khaladka Isku-xidhka Dhinacyada Dhexdooda"

Caqabadda ugu weyn ee la xiriirta manipulators-ka shan-dhidib leh waa isku-dubaridka dhaqdhaqaaqa dhidibka badan. Marka dhammaan shanta dhidib ay isku mar dhaqaaqaan, xawaaraha iyo dardargelinta dhidib kasta waa in si adag loo waafajiyaa, haddii kale "qaladaadka qaabka" (sida leexashada qaabka marka la farsameynayo dusha sare ee qaloocan) ayaa dhici doona. Tani waxay u baahan tahay hagaajin iyada oo loo marayo teknoolojiyada soo socota:

Algorithms-ka hore iyo rogaal-celinta ee Kinematic-ka: Adeegso qaab kinematic shan-dhidib oo sax ah si aad si sax ah u xisaabiso xuduudaha dhaqdhaqaaqa ee dhidib kasta (sida magdhowga xagasha ee dhidibka rogaal-celinta) si looga fogaado khaladaadka ay sababaan qiyaasaha algorithmic. Tusaale ahaan, qaabaynta shan-dhidib ee "qaabka cradle-ka" (dhidibyada A + C), algorithm-ku waa inuu magdhabaa isku-dhafka u dhexeeya xarumaha dhidibka rogaal-celinta iyo kuwa toosan.

Habaynta algorithm-ka Interpolation-ka: Adeegso "interpolation-ka spline" ama "interpolation-ka NURBS" (halkii laga isticmaali lahaa isku-xidhka toosan ee dhaqameed) si loo gaaro dhaqdhaqaaq siman oo loogu talagalay dhidib kasta loona yareeyo khaladaadka saameynta ee ka dhasha isbeddellada degdegga ah ee xawaaraha. Soo-saare qalabka caafimaadka ayaa hagaajiyay saxnaanta mashiinka dusha sare ee isku-dhafka ah ee macmalka ah laga bilaabo ±0.03mm ilaa ±0.015mm isagoo hirgelinaya isku-xidhka NURBS.

Saddexaad. Magdhawga Khaladka: "Habka Sixitaanka" ee Saxnaanta, Isticmaalka Tiknoolajiyada si loo Magdhabo Kala Duwanaanta Dhaxalka ah

Xitaa ka dib marka nidaamyada farsamada iyo adeegga la hagaajiyo, khaladaadka ku jira (sida qaladka kulaylka, qaladka meelaynta, iyo qaladka joomatari) ayaa weli jiri doona, taasoo u baahan farsamooyin magdhaw firfircoon si loo sii yareeyo:

1. Magdhawga Khaladka Kulaylka: "Dilaaga Aan La Arag" ee Isbeddellada Heerkulka

Marka robot shan-dhidible ah uu shaqeynayo, is jiidjiidku wuxuu dhaliyaa kulayl matoorka, boolal rasaas ah, iyo bir hagaha, taasoo keenta ballaarin iyo isbeddel ku yimaada qaybaha. Tusaale ahaan, koror kasta oo 1°C ah oo ku yimaada heerkulka boolal kubbadda ah, dhererku wuxuu kordhaa qiyaastii 11μm/m, taasoo si toos ah u horseedda khaladaad meelaynta dhidibka toosan. Xalalka waxaa ka mid ah:

Qalabka: Ku rakib dareemayaasha heerkulka (sida PT1000) meel u dhow matoorka iyo boolal rasaas ah si aad ula socoto isbeddellada heerkulka waqtiga dhabta ah.

Software: Samee qaab xisaabeed "qalad heerkul-kuleyl" ah (sida qaabka dib-u-celinta toosan) si toos ah loogu xisaabiyo loona magdhabo khaladaadka ku salaysan xogta dareemayaasha. Tusaale ahaan, soo saaraha qalabka mashiinka ayaa isticmaalay magdhowga khaladaadka kulaylka si loo xasiliyo saxnaanta hawlgalka muddada dheer (muddo 8 saacadood ah) ee robot shan-dhidib leh laga bilaabo ±0.025mm ilaa ±0.012mm.

2. Magdhawga Khaladka Meelaynta: Isticmaalka Qalabka Dhexgalka Laser-ka si loo "Hagaajiyo Tallaabo kasta"

Khaladka meelaynta waxaa loola jeedaa leexashada u dhaxaysa booska dhabta ah ee robot-ka iyo booska la amray. Waa in la cabbiraa oo la magdhabaa iyadoo la adeegsanayo qalab gaar ah:
Qalabka Cabbirka: Isticmaal qalabka laysarka ee interferometer-ka (sida Renishaw XL-80) si aad u cabbirto khaladka booska, qaladka soo noqnoqoshada, iyo dib u celinta dhidib kasta.
Habka Magdhawga: Soo geli xogta cabbirka gudaha Robot maxay tahaynidaamka xakamaynta, samee "miiska magdhowga qaladka," oo isticmaal sixitaannada waqtiga-dhabta ah inta lagu jiro dhaqdhaqaaqa. Tusaale ahaan, soo saaraha qaybaha duulista, cabbiraadda laysarka interferometer-ka ayaa yareysay qaladka booska dhidibka X laga bilaabo 0.018mm ilaa 0.006mm.

3. Magdhawga Khaladaadka Joomatari: Ka saarista "Kala Duwanaanta Dhaxalka ah" ee Naqshadeynta Dhismaha

Khaladaadka joomatari ee robot-ka shan-dhidib leh waxaa ka mid ah khaladaadka toosan ee dhidibka iyo khaladaadka ka soo horjeeda dhidibka wareegga, kuwaas oo u baahan magdhow iyada oo loo marayo hababka soo socda:

Hagaajinta Joogtada ah: Isticmaal tilmaame laba jibbaaran iyo garaac ama laysar dhexdhexaad ah si aad u cabbirto joogsiga u dhexeeya dhidibyada toosan (tusaale ahaan, qaladka joogsiga u dhexeeya dhidibyada X iyo Y waa inuu ahaadaa ≤ 0.005 mm/m). Sax qaladkan adoo isticmaalaya shaqada "magdhawga joogsiga" ee nidaamka xakamaynta.

Magdhawga Eccentricity-ga Wareega: Isticmaal ballbar si aad u cabbirto eccentricity-ga dhidibka wareega (tusaale ahaan, kala-goynta u dhaxaysa xarunta wareegga dhidibka A iyo dhidibka Z). Xuduudaha magdhowga eccentricity-ga ayaa markaa lagu daraa qaabka kinematic-ga si looga fogaado leexashada booska dhammaadka ee ay keento eccentricity-ga.

Afaraad. Rakibaadda iyo Hawlgalka: "Furaha Hirgelinta" Saxnaanta; Faahfaahinta Go'aami Natiijooyinka Ugu Dambeeya

Xitaa haddii qalabku uu buuxiyo saxnaanta loo baahan yahay, rakibidda iyo socodsiinta aan habboonayn ayaa weli horseedi karta luminta saxnaanta. Habraacyada soo socda waa in si adag loo raaco:

1. Saldhigga Rakibaadda: Hubi in saldhig deggan oo siman yahay

Shuruudaha Aasaaska: Dusha sare ee ay ku taal robot-ka waa in sibidh lagu daaweeyaa (xoog ≥ C30) iyo dhumuc ≥ 200mm si looga hortago janjeedhka uu keeno dhulka oo da'a.

Hagaajinta Jiifka: Isticmaal heer sax ah (saxnaanta 0.02mm/m) si aad u hagaajiso jirka mashiinka si loo eego jiif ahaan. Khaladka toosan ee dhidibka toosan waa inuu ahaadaa ≤ 0.01mm/m, iyo dhamaadka-wajiga qulqulka ee dhidibka wareega waa inuu ahaadaa ≤ 0.005mm.

2. Hagaajinta Nidaamka Axis-ka: Hagaajinta tallaabo-tallaabo laga bilaabo hal-dhidib ilaa isku-dubarid

Hagaajinta Hal-dhidib: Marka hore tijaabi saxnaanta dhaqdhaqaaqa (qaladka meelaynta iyo ku celcelinta) ee dhidib kasta si gaar ah. Marka saxnaanta hal-dhidibka ay gaarto heerka, u gudub hagaajinta isku-dubaridka dhidibka badan.

Hagaajinta isku-dubaridka: Iyada oo loo marayo tijaabinta jarista tijaabada ama tijaabinta raadraaca waddada (tusaale ahaan, rarista robot-ka iyada oo loo marayo qalooc hore loo dejiyay iyo isticmaalka raadraaca laysarka si loo ogaado leexashada waddada), hagaajinta xuduudaha isku xirka shan-dhidibka si loo hubiyo in saxnaanta qaab-dhismeedka ay buuxiso heerka.

3. Tijaabinta Culayska: Ku dayasho Xaaladaha Hawlgalka Dhabta ah si loo Xaqiijiyo Xasilloonida Saxnaanta

Samee tijaabo culays oo joogto ah muddo 8-12 saacadood ah iyadoo lagu salaynayo "rarka ugu badan" iyo "xawaaraha ugu badan" ee loo isticmaalo wax soo saarka dhabta ah.

Samee hubin saxnaan joogto ah inta lagu jiro baaritaanka (tusaale ahaan, cabbiraadda qaladka booska dhammaadka iyadoo la adeegsanayo tilmaame garaac ah 2dii saacadoodba mar) si loo hubiyo in saxnaantu ay ku jirto xadka la aqbali karo ee xaaladaha culayska.

Shanaad. Dayactirka Maalinlaha ah: "Dammaanad-qaadka Muddada Dheer" ee Saxnaanta: Ka hortagga ayaa ka Wanaagsan Dayactirka

Saxnaanta robot-ka shan-dhidib leh ee servo ayaa hoos u dhici doonta waqti ka dib, sidaa darteed jadwal dayactir joogto ah ayaa lagama maarmaan ah:

1. Dayactirka Qaybaha Gudbinta: Saliidaynta iyo Nadiifinta si loo yareeyo Xidhitaanka

Kubbadaha/Xadhkaha Hagaha: Mari saliid gaar ah (tusaale ahaan, saliid ku salaysan lithium) 50-kii saacadoodba mar oo aad shaqaynayso si looga hortago xirmidda ay keento is jiidjiid qalalan. Nadiifi daboolka boodhka ee birta hagaha bishiiba si aad uga hortagto in boodhka uu soo galo birta hagaha.

Yaraynta Harmonic-ka: Hubi heerka saliidda 200 saacadood kasta oo aad shaqeyso oo ku dar saliid gaar ah (tusaale ahaan, saliidda qalabka yaraynta harmonic-ka) haddii loo baahdo. Beddel saliidda sannad kasta.

2. Dayactirka Nidaamka Servo: Kormeerka Joogtada ah iyo Digniinaha Hore

Encoder: Nadiifi guriga encoder-ka saddexdii biloodba mar oo hubi isku xirka fiilooyinka si aad u hesho amniga si looga hortago faragelinta calaamadaha ay keento fiilooyinka dabacsan.

Darawalka: Hubi marwadaha qaboojinta darawalka bil kasta si ay u helaan shaqada saxda ah oo u nadiifi boorka godadka qaboojinta si looga hortago hoos u dhaca waxqabadka oo ay ugu wacan tahay kulaylka xad-dhaafka ah.

3. Dib-u-hubinta Saxnaanta: Hagaajinta Joogtada ah iyo Sixitaanka Waqtiga ku Habboon

Dib u hubi saxnaanta dhidib kasta saddexdii biloodba mar adoo isticmaalaya qalabka laysarka ama qalabka kubbadda. Haddii qaladku ka sarreeyo heerka (tusaale ahaan, qaladka booska > 0.01mm), dib u magdhabi isla markiiba.

Samee "hagaajin sax ah oo buuxda" sannad kasta, oo ay ku jiraan kormeerka qaab-dhismeedka farsamada, hagaajinta halbeegyada adeegga, iyo cusbooneysiinta magdhowga khaladaadka, si loo hubiyo in qalabku uu sii wado hawlgal sax ah muddada dheer.

Gunaanad: Saxnaanta robot-ka shan-dhidib leh ee servo waa "mashruuc nidaamyo ah," ee ma aha hal tallaabo.

Hubinta saxnaanta robot-ka shan-dhidib leh ee servo waxay u baahan tahay hab nololeed oo dhammaystiran: "naqshadeynta iyo xulashada - wax soo saarka - rakibidda iyo fulinta - dayactirka joogtada ah." Qaab-dhismeedka farsamadu waa aasaaska, nidaamka servo waa xudunta, magdhowga khaladka waa habka, rakibidda iyo dayactirkana waa ilaalinta. Ganacsiyada, marka lagu daro xulashada qalabka saxda ah ee sare, waa muhiim in la horumariyo "miyir-qabka maaraynta saxda ah" - iyada oo loo marayo habayn joogto ah, la socodka xogta, iyo hagaajinta joogtada ah - si loo hubiyo in saxnaanta robot-ku si joogto ah u buuxiso shuruudaha wax soo saarka.

Haddii aad la kulanto arrimo gaar ah oo ku saabsan xakamaynta saxda ah ee robot-ka shan-dhidiblaha ah ee servo (sida qalad xad-dhaaf ah oo ku yimaada hal dhidib ama saxnaan aan ku filnayn inta lagu jiro isku xirka), falanqayn dheeraad ah oo ku salaysan xaaladaha hawlgalka dhabta ah ayaa loo isticmaali karaa in lagu horumariyo xalalka hagaajinta bartilmaameedka ah, taasoo u oggolaanaysa qalabku inuu si dhab ah u xaqiijiyo qiimahiisa "saxnaanta wax soo saarka".
