Lapho irobhothi le-FTC lima ngokuzuma, linqamuka ku-Driver Station, noma lisetha kabusha i-REV Control Hub yalo phakathi nomdlalo, ugesi omiyo (static electricity) uvamise ukuba yimbangela — kodwa akufanele kube umcabango wakho wokuqala. Isixhumi se-XT30 esixegayo sibanga izimpawu ezifanayo futhi sivamile ngendlela efanayo, ngakho-ke hlola izintambo kuqala ngaphambi kokuba uchithe isizini ulandelela ugesi. Amathayili ajwayelekile e-EVA foam angu-5/8-inch asetshenziswa ezinkundleni ze-FIRST Tech Challenge awawudlulisi ugesi (electrical insulators). Njengoba amasondo enjoloba angashiyi zimpawu egijima futhi egudlana nala mathayili, i-chassis iqongelela izinkulungwane zama-volt zikagesi omiyo (electrostatic charge). Lapho nje i-intake yensimbi, ingalo, noma i-chassis ithinta umngcele wensimbi noma elinye irobhothi, lowo gesi uphuma ngendlela elula kakhulu—uvamise ukudlulela ngqo ezintanjeni zezinzwa (sensors) ezingavikelekile, ezintanjeni ze-motor encoder, noma kumasekhethi angaphakathi e-Control Hub.

Ngaphambi Kokubeka Icala Ugesi Omiyo: Hlola Izixhumi ze-XT30

Abeluleki Bezobuchwepheshe Basenkundleni (Field Technical Advisors) babona amaqembu elahlekelwa yizinsuku zonke efuna inkinga kagesi omiyo kanti iphutha langempela lingelokusebenza kwemishini: izikhonkwane zesilisa ze-XT30 ku-REV Control Hub ne-Expansion Hub ziyaxega. Isikhonkwane ngasinye sinezicucu ezine okufanele zihlale zivulekile ukuze zibambane; ukuxhuma ngokuphindaphindiwe, noma isisindo sentambo elenga embobeni, kuyazicindezela, bese kuthi ukuxhumana okubukeka kungene kahle kunqamuke ngenxa yokudlikizela. Umhlahlandlela we-REV wokuxazulula izinkinga uxwayisa ngokuthi isikhonkwane singacindezelwa kakhulu ngisho nalapho kusekhona isikhala esibonakalayo phakathi kwezicucu, ngakho ukubuka ngeso akusona isivivinyo esithembekile — vula irobhothi, nhlikiza isixhumi, bese ubuka ama-LED e-hub.

Hlola izimpawu ngale ndlela elandelayo ngaphambi kokusebenzisa izixazululo zokuvimbela ugesi omiyo:

1. I-hub icimile noma iqalise kabusha. Irobhothi lilahlekelwe amandla kagesi. Sola izindawo zokuxhuma ze-XT30 kuqala, bese ulandela ibhethri nesixhumi salo — hhayi ugesi omiyo.
2. Ama-LED e-hub ahlale eluhlaza sonke isikhathi. Irobhothi alikaze lisethe kabusha, ngakho iphutha lisendimeni yokuxhumana noma esiteshini somshayeli (bheka ngezansi), hhayi endleleni yamandla kagesi yerobhothi.
3. Izintambo zihloliwe zaphuma zingenaphutha, izimpawu zisaqhubeka. Manje ukusola ugesi omiyo kunesisekelo esihle, futhi izindlela zokunciphisa ezichazwe ngezansi zikufanele ukuchitha isikhathi kuzo.

Mayelana nokulungisa, i-REV inikeza imiyalelo yokuvula kabusha ngokucophelela izicucu ezicindezelekile usebenzisa insimbi encane kakhulu njengommese we-X-ACTO — ukwenza kancane kwanele, kanti isikhonkwane esivulwe ngokweqile sonakele ngokuphelele — kanye nokwengeza isivikelo sokudonsa (strain relief) ukuze kungabikho sisindo sentambo esilenga esixhumini. Umthetho u-R607 uvumela futhi izixhumi ze-COTS eziphakathi nendawo, ngakho i-adaptha ye-Anderson Powerpole iyindlela esemthethweni yokusuka ku-XT30 ezintanjeni ozixhuma njalo. Bheka umhlahlandlela we-REV wokuxazulula izinkinga ze-Control Hub kanye nevidiyo echazayo ethi “Your FTC Robot Keeps Disconnecting? This Is The Fix.”

Isici Se-Highveld: Kungani Izindawo ZaseNingizimu Afrika Zihlupheka Kakhulu

Ukuqongelelwa kukagesi omiyo kulawulwa ngqo umswakama ohlobene womoya (relative humidity). Ezindaweni ezisogwini ezifana neKapa noma iTheku, umswakama womoya awuvamile ukwehla kakhulu kangangokuthi ugesi oyingozi we-Electrostatic Discharge (ESD) uqongeleleke ngaphandle kokuvinjwa, njengoba umswakama osendimeni usiza ukusabalalisa ugesi ongaphezulu. Izindawo ezisemaphakathi nezwe—ikakhulukazi amahholo ezemidlalo ezikoleni kanye namahholo e-Gauteng nase-Free State ngesikhathi somqhudelwano wasebusika nentwasahlobo eyomile—ngokuvamile ziba nomswakama ongaphakathi owehla ngaphansi kuka-20%.

Kulezi zimo ezomile, eziphakeme ngezindawo, umthelela we-triboelectric phakathi kwamasondo e-synthetic (njengama-compliant wheels, amaphrinti e-TPU, noma ama-roller e-silicone) kanye ne-closed-cell EVA foam kusebenza njengejeneretha yezimboni ye-Van de Graaff. Uma iqembu lakho lenze futhi lavivinya izinqubo ezizimele (autonomous routines) ezingeni lolwandle noma egumbini elinomswakama, izingxenye zenu zikagesi zingasebenza ngokuphelele endaweni yokusebenzela kodwa zibe nezinkinga zokuxhumana eziphindaphindwayo enkundleni yomqhudelwano.

Indlela i-ESD Eyikhubaza Ngayo i-REV Control Hub

I-REV Control Hub ne-Expansion Hub zisebenzisa ama-bus okuxhumana angaphakathi (I2C, RS485, USB) ukuphatha amamotho, ama-servo, nezinzwa. Lapho i-ESD ihlasela:

• Ukuvaleka kwe-I2C Bus: Izinzwa zombala (colour sensors) nezinzwa zebanga (distance sensors) ze-REV zisebenza ngogesi ongu-3.3V logic. Ukukhuphuka okwesikhashana kwe-voltage entanjeni ye-I2C engavikelekile konakalisa umugqa wewashi noma wedatha, okwenza i-I2C bus ye-Control Hub ivaleke ngokuphelele bese irobhothi lonke lima kuze kube kucinywa futhi kuvulwe kabusha amandla kagesi.
• Ukunqamuka kwe-USB: Uma usebenzisa ifoni yangaphandle noma ama-webcam e-USB, isikhonkwane somhlaba (ground pin) sesixhumi se-USB sivame ukudonsa ugesi ophumayo, okuphoqa i-Linux kernel eku-Hub ukuba isethe kabusha isilawuli sayo se-USB.
• Ukusethwa Kabusha Kwe-Optical ne-Magnetic Encoder: Izintambo ezinde ze-encoder ezihamba eceleni kwe-aluminium yesakhiwo zisebenza njengama-antenna amagagasi kazibuthe kagesi (electromagnetic pulses), okonakalisa idatha yendawo noma kushise ama-diode okuvikela okokufaka kwedijithali.

Ukunqamuka Okungeyona Inkinga Yerobhothi: Ukuvaleka Kwe-Driver Hub

Kunesinye isimo esiphathwa ngephutha njengenkinga kagesi omiyo ohlangothini lwerobhothi. Uma i-Driver Hub ima, ilahlekelwa yi-gamepad, noma iyeka ukuxhumana nerobhothi ngenkathi ama-LED e-Control Hub ne-Expansion Hub ehlala eluhlaza sonke isikhathi, irobhothi alikaze lisethe kabusha futhi alikaze lilahlekelwe amandla — iphutha lisesiteshini somshayeli. Ama-FTA abika lokhu njengesigameko se-ESD noma se-EMI emisebeni esingena ezintanjeni ze-USB ze-gamepad, nokuthi ukubopha ama-ferrite core kulezo zintambo kuyayixazulula le nkinga cishe kuzo zonke izikhathi. Lesi yisixazululo esifanayo nendlela yesi-4 ngezansi, esetshenziswe kolunye uhlangothi lokuxhumana, futhi asibizi kangako ukuba siphathwe ebhokisini lamathuluzi (pit kit) njengesinyathelo sokuzivikela.

Izindlela Zokunciphisa Ezivumelekile Ngokwemithetho Yomdlalo

Imithetho ivula indlela encane kodwa ephumelelayo: ungaxhuma irobhothi ngokwalo futhi uhlukanise izingxenye zakho zikagesi, kodwa awuvunyelwe neze ukuxhuma irobhothi nenkundla yomdlalo (arena). Isigaba 12.6 se-Ncwajana Yomncintiswano sivumela ukuxhumana okukodwa kuphela kokumisa ugesi emhlabathini (grounding) — ibhande le-resistive eligunyaziwe phakathi komhlaba wesistimu yokulawula nohlaka lwe-ROBOT — futhi sinqabela ngokucacile noma iyiphi ingxenye noma indlela eklanyelwe ukuxhuma lolo hlaka emhlabathini wenkundla. Zonke izindlela ezingezansi zihambisana nalowo mthetho.

1. Ibhande Eliqinisekisiwe Lokumisa Ugesi le-Resistive (Uhlaka luya Ezintweni Zikagesi — Aluyi Enkundleni Neze)

Okuwukuphela kwendlela yokumisa ugesi emhlabathini i-FIRST eyivumelayo ihamba ngaphakathi kwerobhothi: ibhande le-resistive eligunyaziwe elihlanganisa umhlaba wesistimu yokulawula nohlaka lwe-ROBOT, ukuze uhlaka nezingxenye zikagesi zibe namandla kagesi afanayo esikhundleni sokukhiphana izinhlansi ngentambo yenzwa. Umthetho u-R605 encwajaneni ye-BIOBUZZ ka-2026-2027 (umthetho ofanayo kwakungu-R611 ku-DECODE ka-2025-2026) ubeka izingxenye ezingezona ezingekho emthethweni kuphela:

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

Isiphetho esisodwa kufanele siye engxenyeni ye-COTS egcwele enesixhumi se-XT30 (i-REV Control Hub, ibhloko yokusabalalisa amandla ye-XT30, noma i-adaptha ye-Powerpole-to-XT30); esinye kufanele siboshwe ngqo ohlakeni kusetshenziswa itheminali ye-resistive yebhande. I-anodising ayiwudlulisi ugesi, ngakho-ke khuhla noma ulayishe indawo yokuthinta ngaphambi kokuba uqinise itheminali eyindilinga, futhi ukhumbule ukuthi amakhamera, ama-LED strip nezinye izi-encoder kufika nezindawo zensimbi ezixhumene nomhlaba okufanele zihlale zihlukanisiwe nohlaka.

Ungaxhumi irobhothi emhlabathini wenkundla. Ikhebula elidonswayo elihambisa ugesi (conductive drag chain), intambo yethusi (copper braid) noma umucu wokuvimbela ugesi omiyo ohuduleka kusukela ku-chassis kuye emathayilini e-foam akukho emthethweni futhi akukaze kube semthethweni kumasizini amaningi. U-R605.C ucacile: “azikho IZINGXENYE ZEROBHOTHI noma IZINDLELA ZOKUSEBENZA eziklanyelwe ukuxhuma uhlaka lwe-ROBOT emhlabathini we-FIELD.” Abahloli bayakuhlola lokhu, kanti isisombululo ukukhiphela ugesi ku-chassis yakho, hhayi enkundleni.

2. Ukuxhuma Uhlaka Emhlabathini Endaweni Eyodwa Kuphela (Single-Point Frame Grounding)

Qinisekisa ukuthi zonke izingxenye zesakhiwo (amasistimu e-slide, amapuleti e-intake, amashaneli e-drivetrain) zinokuxhumana okuqhubekayo kwensimbi nensimbi okudlulisa ugesi. I-aluminium ene-anodised ayiwudlulisi ugesi ebusweni bayo; uma amapuleti amabili ehlanganiswa ngaphandle kokususa ungqimba lwe-anodised, ingxenye eyodwa ingaba namandla kagesi ahlukile kunenye i-chassis yonke, ikhiphele ugesi ezintweni zakho zikagesi lapho zithintana. Sebenzisa ama-star washer noma ukhuhle i-anodising eduze kwamabhawodi abalulekile okuhlanganisa izakhiwo.

3. Ukuhlukanisa Nokuvikela Izinto Zikagesi Ngesikhala

Ungalokothi uhlanganise i-REV Control Hub ngqo ku-aluminium engagayiwe ngaphandle kwento evimbela ugesi. Hlanganisa i-Hub kuma-bracket e-PETG anyatheliswe nge-3D, ishidi le-polycarbonate, noma ama-nylon standoff. Lokhu kuqinisekisa ukuthi noma yikuphi ukuhlasela kwe-ESD ezingeni le-chassis akungeni ngqo esikhaleni se-aluminium se-hub nasendaweni engaphakathi ye-PCB ground plane.

4. Ama-Ferrite Choke Nokuhlelwa Kwezintambo

Zungezisa izintambo ezinde zezinzwa, ezama-webcam, neze-servo kuma-snap-on ferrite choke eduze ngangokunokwenzeka nezimbobo ze-Control Hub. Ama-ferrite choke acindezela ukukhuphuka kwamaza aphezulu e-voltage okubonakala ngokukhipha izinhlansi ze-ESD. Yenza okufanayo nasezintanjeni ze-gamepad ku-Driver Hub, ngenxa yesizathu esishiwo ngenhla. Gcina izintambo zezimpawu zihamba phakathi nendawo yerobhothi, zivikelwe ngaphakathi kwe-U-channel aluminium, esikhundleni sokuziyeka zivele ngaphandle emaphethelweni lapho kungenzeka zithinteke ngezinto zenkundla.

Uhlu Lokuhlola Ngaphambi Komdlalo Lwezindawo Ezomile

Amaqembu ancintisana ezindaweni ezisemaphakathi nezwe kufanele afake izinyathelo zokunciphisa ugesi omiyo ohlelweni lwawo lwasemgodini wokusebenzela (pit routine):

• Vivinya zonke izindawo zokuxhuma ze-XT30 ngokuzinyakazisa ngenkathi irobhothi livuliwe, futhi uhlole izikhonkwane zesilisa ukuthi azicindezelekile yini izicucu zazo. Lokhu kuthatha umzuzu owodwa futhi kuqeda imbangela evame kakhulu yokunqamuka phakathi nomdlalo ngaphambi kokuba usole ugesi omiyo.
• Buza umhleli womcimbi ukuthi amathayili aphathwe ngesibulali-gesi esomiyo yini. Umhlahlandlela we-FIRST we-ESD uncoma ukuthi izindawo zomcimbi zifafaze inkundla ngesifutho sokuvimbela ugesi omiyo esifana ne-ACL Heavy Duty Staticide — lokho kuyisinqumo somhleli, hhayi seqembu. Ungafaki izifutho, izithambisi noma ama-gel emasondweni akho: u-R201 ubala uketshezi nezinto ezingama-gel njengengozi yokudala ukungcola, futhi noma yini edlulela emathayilini iba yinkinga yomcimbi wonke, hhayi eyakho kuphela.
• Xhuma amalungu eqembu emhlabathini ngokuthinta umngcele wenkundla ngaphambi kokuthinta irobhothi ngesikhathi sokulungisa inkundla.
• Hlola konke ukuxhumana kwezintambo zohlobo lwe-snap-fit ukuqinisekisa ukuthi izikhonkwane zezintambo ezingenalutho azivelanga emoyeni ovulekile.

Ukuze uthole ihadiwe eqinisekisiwe, amamojula e-REV ashintshwayo, nezingxenye ezilungele umncintiswano, bheka umhlahlandlela wezobuchwepheshe we-FTC wakwa-Sheen Robotics noma u-ode izintambo ezisezingeni lomncintiswano ngqo esitolo sakwa-Sheen Robotics.

Ukulungisa, 29 Agasti 2026: inguqulo yangaphambili yalesi sihloko yabala ibhande le-passive bleed elihuduleka kusukela ohlakeni lwerobhothi kuye emathayilini e-foam njengesinyathelo esivumelekile ngokwemithetho yomdlalo. Akunjalo — u-R605.C uvimbela ukuxhuma uhlaka lwe-ROBOT emhlabathini we-FIELD — futhi leso sigaba sibhalwe kabusha ngaphansi kwebhande le-resistive eligunyaziwe elihlanganisa uhlaka nezinto zikagesi. Sibonga kakhulu kumfundi okuphawulile lokhu.

Kubuyekezwe ngo-31 Agasti 2026: ngokweseluleko se-FTA esebenza emicimbini ye-FTC e-Texas, lesi sihloko asisasho ukuthi ugesi omiyo “uvame” ukuba yimbangela. Izixhumi ze-XT30 ezixegayo zibanga ukunqamuka okuningi ngokulinganayo, ngakho-ke ukulandelana kokuxilonga manje sekubekwe kuqala, futhi kwengezwe nesigaba esimayelana nokuvaleka kwe-Driver Hub.
