Uma irobhothi le-FTC lingqikaza kungazelelwe, linqamuka ku-Driver Station, noma i-REV Control Hub yalo iziqala kabusha phakathi nomdlalo, imvamisa umsuka wenkinga ugesi we-static. Amathayela ajwayelekile e-EVA foam angu-5/8 wentshi asetshenziswa ezinkundleni ze-FIRST Tech Challenge ayizivimbeli zikagesi. Njengoba amasondo enjoloba angashiyi mibala egingqika futhi ehlikihlana nalawa mathayela, uhlaka lwerobhothi lubuthelela izinkulungwane zamavolti wamandla kagesi we-static. Ngomzuzwana lapho i-intake yakho yensimbi, ingalo, noma uhlaka lukhwehlela umngcele wensimbi noma elinye irobhothi, lawo mandla ayakhishwa adlule ngendlela enokumelana okuncane kunazo zonke—ngokuvamile aqhamukele ngqo ezintanjeni zezinzwa ezingavikelekile, ezintanjeni zama-motor encoder, noma kusekhethi yangaphakathi ye-Control Hub.

Umthelela WeHighveld: Kungani Izindawo ZaseNingizimu Afrika Zihlushwa Kakhulu

Ukubuthana kukagesi we-static kulawulwa ngqo umswakama oqhathanisiwe. Ezindaweni ezisogwini olunjengeKapa noma iTheku, umswakama oqhathanisiwe awuvamile ukwehla ufike ezingeni eliphansi ngokwanele lokuthi Ukukhishwa Kukagesi We-static (i-ESD) okuyingozi kubuthane ngaphandle kokuvinjwa, ngoba umswakama osemoyeni usiza ekuchitheni amandla kagesi asebusweni bezinto. Izindawo ezingaphakathi ezweni—ikakhulukazi amahholo ezemidlalo asezikoleni namahholo emihlangano eGauteng naseFree State ngesikhathi sasebusika nasemiqhudelwaneni eyomile yasentwasahlobo—zivame ukubona umswakama wangaphakathi wehlela ngaphansi kuka-20%.

Kulezi zimo ezomile, eziphakeme phezu kwezinga lolwandle, umphumela we-triboelectric phakathi kwamasondo enziwe ngezinto zokwakhiwa (njengama-compliant wheel, okuphrintwe nge-TPU, noma ama-roller e-silicone) ne-EVA foam yamaseli avaliwe usebenza njengejeneretha ye-Van de Graaff yezinga lezimboni. Uma iqembu lakho lakhe futhi lahlola izinhlelo zalo ezizimele ezingeni lolwandle noma egumbini elinomswakama, izingxenyekazi zakho zikagesi zingasebenza ngaphandle kwephutha ekamelweni lokusebenzela kodwa zibe sezihlangabezana nokuphahlazeka kokuxhumana okuphindaphindekayo enkundleni yomqhudelwano.

Indlela i-ESD Ekhubaza Ngayo i-REV Control Hub

I-REV Control Hub ne-Expansion Hub zisebenzisa ama-bus wokuxhumana angaphakathi (I2C, RS485, USB) ukuze zilawule ama-motor, ama-servo nezinzwa. Uma i-ESD ishaya:

• Ukukhiyeka Kwe-bus ye-I2C: Izinzwa zemibala ze-REV nezinzwa zebanga zisebenza nge-logic ka-3.3V. Ukwenyuka kwevolthi okuyisikhashana entanjeni ye-I2C engavikelekile konakalisa ulayini wewashi noma owedatha, kufake i-bus ye-I2C ye-Control Hub ekukhiyekeni okungenakulungiseka okumisa irobhothi lonke kuze kucishwe kuphinde kuvulwe ugesi.
• Ukunqamuka Kwe-USB: Uma usebenzisa ifoni yangaphandle noma amawebhukhamera e-USB, iphinini le-ground lesixhumanisi se-USB livame ukumunca lokho kukhishwa kukagesi, liphoqe i-kernel ye-Linux ese-Hub ukuba iqale kabusha isilawuli sayo se-USB.
• Ukuqala Kabusha Kwama-encoder We-optical Nawe-magnetic: Izintambo ezinde zama-encoder ezidluliswa eceleni kwe-aluminium yesakhiwo zisebenza njengama-antenna wemidlandla ye-electromagnetic esakazekayo, zonakalise idatha yendawo noma zishise ama-diode avikela okufakwayo kwedijithali.

Amasu Okunciphisa Avunyelwe Imithetho Yomdlalo

Imithetho ishiya indlela emxinene kodwa esebenzayo: ungaxhuma irobhothi kulo ngokwalo futhi wehlukanise izingxenyekazi zakho zikagesi, kodwa awukwazi neze ukuxhuma irobhothi enkundleni. Isigaba 12.6 se-Competition Manual sivumela ukuxhumeka okukodwa nje kwe-grounding — i-strap enokumelana egunyaziwe phakathi kwe-ground yesistimu yokulawula nohlaka lwe-ROBOT — futhi sivimbela ngokusobala noma iyiphi ingxenye noma indlela eyakhelwe ukuxhuma lolo hlaka enkundleni. Onke amasu angezansi ahlala ngaphakathi kwalowo mngcele.

1. I-Strap Ye-grounding Enokumelana Egunyaziwe (Uhlaka Kuya Ezingxenyekazini Zikagesi — Hhayi Neze Enkundleni)

Ukuphela kwendlela ye-grounding evunyelwe yi-FIRST ihamba ngaphakathi erobhothini: i-strap enokumelana egunyaziwe exhuma i-ground yesistimu yokulawula ohlakeni lwe-ROBOT, ukuze uhlaka nezingxenyekazi zikagesi kube sezingeni elifanayo esikhundleni sokuqhamukelana ngentambo yenzwa. Umthetho u-R605 encwadini ye-BIOBUZZ ka-2026-2027 (lo mthetho ofanayo bewungu-R611 ku-DECODE ka-2025-2026) ubala izingxenye ezikuphela kwazo ezisemthethweni:

• AndyMark Resistive Grounding Strap — am-4648a
• REV Resistive Grounding Strap — REV-31-1269
• Swyft Grounding Cable — SR-Ground-01

Umkhawulo owodwa kumele uhlale engxenyeni engu-COTS ngokugcwele enesixhumanisi se-XT30 (i-REV Control Hub, ibhulokhi yokusabalalisa amandla ye-XT30, noma i-adaptha ye-Powerpole-to-XT30); omunye kumele ubethelwe ngqo ohlakeni ngesixhumanisi se-strap esinokumelana. I-anodising iyisivimbeli sikagesi, ngakho hwaya noma usile indawo yokuthintana ngaphambi kokuqinisa isixhumanisi esiyindilinga, futhi khumbula ukuthi amakhamera, izintambo ze-LED namanye ama-encoder afika nezimbozo zensimbi eze-grounded okumele zihlale zihlukanisiwe nohlaka.

Ungaxhumi irobhothi enkundleni nge-ground. Iketanga elidonswayo eliphathisa ugesi, i-copper braid noma ustripi we-anti-static odonsakala usuka ohlakeni luye emathayeleni e-foam awukho emthethweni, futhi sekuyizinkathi eziningi ungekho. U-R605.C usho ngokucacile: “azikho IZINGXENYE ZEROBHOTHI noma AMASU akhelwe ukuxhuma uhlaka LWEROBHOTHI ENKUNDLENI ngogesi.” Abahloli bayakuhlola lokhu, futhi isixazululo ukukhiphela amandla kagesi ohlakeni lwakho, hhayi enkundleni.

2. I-grounding Yohlaka Endaweni Eyodwa

Qiniseka ukuthi zonke izingxenyana zesakhiwo (izinhlelo zokushibilika, amapuleti we-intake, imisele ye-drivetrain) zinokuqhubeka kukagesi okungaphazamiseki insimbi-nensimbi. I-aluminium e-anodised ayiphathisi ugesi ebusweni bayo; uma amapuleti amabili ehlanganiswa kungaphulwanga ungqimba lwe-anodising, ingxenyana eyodwa ingaba nezinga elehlukile kunalo lonke uhlaka, bese ikhiphela amandla kagesi ezingxenyekazini zakho zikagesi lapho zithintana. Sebenzisa ama-star washer noma uhwaye i-anodising ezungeze amabhawodi abalulekile ahlanganisa isakhiwo.

3. Ukwehlukaniswa Nokubekwa Kwezingxenyekazi Zikagesi

Ungalokothi ubethele i-REV Control Hub ngqo ku-aluminium eluhlaza ngaphandle kwesithiyo esivimbela ugesi. Bethela i-Hub kuma-bracket we-PETG aphrintwe nge-3D, kushidi we-polycarbonate, noma kuma-standoff e-nylon. Lokhu kuqinisekisa ukuthi noma ikuphi ukushaya kwe-ESD ezingeni lohlaka akungeni ngqo esikhwameni se-aluminium se-hub nasendaweni ye-ground ye-PCB yangaphakathi.

4. Ama-ferrite Choke Nokuhlelwa Kwezintambo

Songa izintambo ezinde zezinzwa, zamawebhukhamera nezama-servo ngama-ferrite choke okuxhunywayo eduze ngangokunokwenzeka nezikhala ze-Control Hub. Ama-ferrite choke acindezela ukwenyuka kwevolthi okusezingeni eliphezulu okuyimpawu yokuqhamuka kwe-ESD. Gcina izintambo zesignali zidlula maphakathi nerobhothi, zivikelwe ngaphakathi kwe-aluminium ye-U-channel, kunokuba zihambe zisobala emaphethelweni angaphandle lapho kwenzeka khona ukuthintana nezinto zenkundla.

Uhlu Lokuhlola Ngaphambi Komdlalo Ezindaweni Ezomile

Amaqembu aqhudelana ngaphakathi ezweni kufanele afake ukunciphisa ugesi we-static ohlelweni lwawo lwasepitini:

• Buza umphathi womcimbi ukuthi amathayela alungisiwe yini. Iziqondiso ze-ESD ze-FIRST uqobo zincoma ukuthi izindawo zibhoce inkundla ngesipreyi se-anti-static esifana ne-ACL Heavy Duty Staticide — leso yisinqumo somphathi womcimbi, hhayi seqembu. Ungafaki izipreyi, ama-softener noma ama-gel emasondweni akho: u-R201 ubala izinto eziwuketshezi nama-gel njengengozi yokungcolisa, futhi noma yini edlulela emathayeleni iyinkinga yomcimbi, hhayi eyakho kuphela.
• Yenza amalungu eqembu enze i-ground esithiyweni somngcele ngaphambi kokuthinta irobhothi ngesikhathi kulungiswa inkundla.
• Hlola konke ukuxhumeka kwezintambo okucofwayo ukuqinisekisa ukuthi amaphinini ezintambo angembozwanga awavezwanga emoyeni ovulekile.

Ukuze uthole izinsiza zomshini eziqinisekisiwe, amamojula e-REV okushintsha, nezingxenye ezilungele umqhudelwano, bheka umhlahlandlela wobuchwepheshe we-FTC we-Sheen Robotics noma uthenge izintambo zezinga lomqhudelwano ngqo esitolo se-Sheen Robotics.

Ukulungisa, 29 Agasti 2026: inguqulo yangaphambilini yalesi sihloko yayibala i-strap ekhipha amandla kagesi engasebenzi ngamandla edonswa isuka ohlakeni lwerobhothi iye emathayeleni e-foam njengendlela yokunciphisa evunyelwe imithetho yomdlalo. Ayikho emthethweni — u-R605.C uvimbela ukuxhuma uhlaka LWEROBHOTHI ENKUNDLENI nge-ground — futhi leso sigaba sibhalwe kabusha sizungeza i-strap enokumelana egunyaziwe esuka ohlakeni iye ezingxenyekazini zikagesi. Siyabonga kumfundi owakuphawula lokhu.
