"Lawa ngama-motor abiza u-$200 aphuka emasontweni ayishumi okuqala"

Uma ufundisa i-robotics, usalwazi kakade lolu hlobo lwezinto. Amakhithi afika ngoJanuwari ebukeka engenakonakala. Sekuphela ithemu lokuqala usunedrowa eligcwele ama-motor afile, ibhodi lokulawula elingavuki, nesethi yekilasi engasahlukaniseki ngokulinganayo ngamaqembu. Nangu uthisha wesikole esimaphakathi echaza khona kanye lokho ku-VEX Forum:

"Kuwo wonke ama-motor angama-32 asemakhithini ayisi-8, ama-4 asephukile... Lawa ngama-motor abiza u-$200 aphuka emasontweni ayishumi okuqala okusetshenziswa"

— VEX Forum, "Incredibly Frustrated - Broken Motors", Mashi 2024

Okubuhlungu kuleyo ngxoxo akulona izinga lokuhluleka. Yikho ukuthi abasekeli be-VEX babeka ama-motor esigabeni "sezinto eziphelayo" base benqaba isicelo sewaranti. Izingxenye irobhothi elingenakunyakaza ngaphandle kwazo zaphathwa njenge-inki yephrinta.

Ama-motor ayisiqalo nje. Ohlangothini lwe-micro:bit, amabhodi uqobo aqinile, kodwa konke okuwazungezile kudla isikhathi sokufundisa:

"Nginguthisha we-STEM ofundisa ukubhala ikhodi ngama-micro:bit emakilasini ami ebanga lesi-7. Cishe ngichitha ihora nsuku zonke ngisiza abafundi ukulungisa amaphakethe amabhethri angasebenzi. … Ngizamile ukuthenga kubahlinzeki abehlukene, kodwa bonke kubukeka bengamanyala."

— r/microbit, Okthoba 2024

Ihora ngosuku lisho amahora amahlanu ngeviki esikhathini sikathisha ofundele umsebenzi wakhe sichithwa ekunyakaziseni izixhumi zamabhethri. Bese kuba khona ukuhluleka okungabonwa muntu kwenzeka:

"Silahlekelwe ama-hub okulawula amathathu ngonyaka odlule ngenxa kagesi omile"

— r/FTC, Mashi 2026

Kanti kukhona nokuncipha okuhamba kancane okungalokothi kufike ezibalweni zokuhluleka:

"Inkinga ephindaphindekayo kube ukulahleka kwempahla ngenxa yokunganaki nokungacabangi okujwayelekile kwabasakhula."

— r/teaching, Februwari 2024

Lo thisha wokugcina ubechaza "amabhokisi asemabhokisini" empahla ye-VEX, ye-Raspberry Pi neye-Arduino. Lolu hlobo lwenkinga alukhethi mthengisi. Yonke into iyaphuka, iyaphelelwa amandla noma iyanyamalala, kanti izindleko zokushintsha bezingekho nhlobo esabelweni semali.

Kungani amakhithi asekilasini ephuka, nokuthi kungani amawaranti engakusindisi

Ama-motor enza umsebenzi onzima kunayo yonke evikelwe kancane kunakho konke

I-motor elisirobhothini sasekilasini livinjelwa ezindongeni, liphoqwe ukujika emuva ngesandla, futhi lixhunywe ezingalweni izingane ezencika kuzo. Abathengisi bayakwazi lokhu, yingakho ulimi "lwezinto eziphelayo" luvela ezimpendulweni zewaranti. Yingakho futhi intengo yokushintsha ibuhlungu. Uthisha oyedwa obeqhathanisa ama-platform wakubeka ngokusobala:

"Bengingasebenzisa i-LEGO Education/EV3/Spike Prime, kodwa ibiza kakhulu kabi ($400 ngekhithi ngalinye lemfundo) … Nama-motor abiza kakhulu (kimi) ngo-$84."

— r/robotics, Januwari 2025

Uma i-motor elilodwa lokushintsha libiza ingxenye ebalulekile yekhithi lonke, ukuhluleka ngakunye kuphenduka ingxoxo yesabelomali esikhundleni sokushintshana kwemizuzu emihlanu.

Ugesi omile uyisibulali samabhodi esithule

Ukukhishwa kukagesi omile akubaneki ngendlela ebonakalayo emandleni kagesi abulala i-hub yokulawula. Umfundi uhudula izinyawo ekhaphethini emoyeni owomile wasebusika, athinte ama-pin, bese ibhodi ebelisebenza izolo alisavuki nanini. Ngenxa yokuthi awukho umonakalo obonakalayo, lokhu kuhluleka kubukeka kwenzeka nje, kusolwe "izinto zikagesi ezishibhile", futhi cishe akulokothi kufakwe ngaphansi kwewaranti.

Izixhumanisi namaphakethe amabhethri yikho okuhluleka kuqala kunakho konke

I-VEX Forum yodwa ikhombisa izingxoxo ezingaphezu kweziyisishiyagalombili ezehlukene mayelana nokuhluleka kwe-hardware yasekilasini: ubuchopho be-V5 obuphukile, amapotho afile, izixhumanisi ze-micro-USB eziqhephukile. Ikakhulukazi i-micro-USB ayizange yakhelwe ukuphathwa ngodli nsuku zonke ekilasini yizingane ezineminyaka eyishumi nambili. Amaphakethe amabhethri enziwe ngabanye ayindaba efanayo emhlabeni we-micro:bit: izixhumi ezishibhile, izintambo ezincane, futhi kungekho zinga eliphansi lekhwalithi kubo bonke abahlinzeki.

Izabelomali zikhokhela ukuthenga, hhayi ukondliwa kwamakhithi

Izikole zabela imali yokuqalisa okukhazimulayo, hhayi eyonyaka wesibili. Okuthunyelwe ku-r/Teachers okwathandwa kakhulu (amavoti angu-164) kwabika isabelomali se-STEM nesesayensi seminyaka emibili sisonke esingu-$100. Sisonke. Uma isabelomali sama-spare siwuziro, i-motor lokuqala eliphukayo liqala ukubala kwehla: amakhithi ayahlanganiswa, amaqembu ayakhula, futhi ekugcineni uhlelo lufa buthule kunekhabhathi eligcwele i-hardware esebenza uhhafu. Ezikoleni zaseNingizimu Afrika, engeza nesandiso sokungenisa impahla ivela phesheya: ama-spare amaningi kufanele athunyelwe emazweni omhlaba, okusho amasonto okulinda kanye nezintela zasemngceleni ngaphezu kwerandi elibuthakathaka.

Okusebenza ngempela: uhlelo lokwenza impahla ilungiseke

Awukwazi ukuvimba amakhithi ukuba angaphuki. Ungakwazi ukuvimba ukuphuka ukuba kukhansele izifundo. Hlukanisa inkinga ibe yilokho okuhlolayo ngaphambi kokuthenga nalokho okusebenzisayo emva kokuthenga.

Ngaphambi kokuba uthenge: imibuzo emihlanu ohlola ngayo umthengisi

1. Ngingakwazi yini ukuthenga i-motor elilodwa vo? Hhayi iphakethe lama-4, hhayi "isipakethe sensiza". Uma into encane kunazo zonke ongayithenga kuyikhithi, ukuhluleka ngakunye kukubiza ikhithi lonke. Shiya lowo mthengisi.
2. Ngingayithola yini lapha ekhaya? I-spare elithunyelwa ngaphakathi ezweni lifika ngezinsuku. I-spare okumele lidlule emngceleni lifika ngamasonto futhi libiza ngaphezu kwentengo ebhaliwe. Ezikoleni zaseNingizimu Afrika lo mbuzo owodwa yiwona ochaza kakhulu izindleko zokugcina impahla.
3. Yini ephuka kuqala, futhi inamathiselwe kanjani? Buza ngezixhumanisi ngqo. I-micro-USB nezixhumi zamabhethri ezibambana nje yizindawo ezaziwayo zokuhluleka; izixhumanisi ezikhiyayo noma ezingena ngendlela eyodwa kuphela zisinda kangcono kakhulu emakilasini.
4. Thola isimo sewaranti sibhaliwe phansi. Buza ngqo: ingabe ama-motor ayizinto eziphelayo? Ingabe ukuhluleka okubangelwa ugesi omile kufakwa ngaphansi kwewaranti? Impendulo yomthengisi ngaphambi kokuthengiselana ibaluleke ngaphezu kwanoma yiluphi ubhukwana lokukhangisa.
5. Ingabe ikhona indlela yokuqhubeka ngaphandle kwe-hardware? Uma i-platform inesilingisi esifanele, ikhithi eliphukile liba yinkinga encane esikhundleni sokuba libe yisifundo esilahlekile.

Emva kokuthenga: phatha ilebhu njengomtapo wolwazi

• Nika ikhithi ngalinye nengxenye enkulu ngayinye inombolo. Abafundi basayina lapho bethatha amakhithi nalapho bewabuyisa, futhi imizuzu emibili yokugcina yesifundo ngasinye ichithwa kubalwa izingxenye. Yilona kuphela ikhambi elaziwayo "lokungacabangi okujwayelekile kwabasakhula".
• Fundisa imikhuba yokuvikela ugesi omile. Thinta into yensimbi ngaphambi kokuphatha amabhodi, gcina amabhodi ezikhwameni zawo uma engasetshenziswa, futhi ungalokothi uphathe izinto zikagesi ngaphezu kwekhaphethi. Ama-hub okulawula amathathu afile akhokhela izikhwama eziningi zokuvikela ugesi omile.
• Khipha amabhethri ngaphambi kokuba akuphoxe. Faka amalebula emaphaketheni, ubhale usuku kuwo, bese ulahla lawo angathembekile. Ihora ngosuku lokuhlunga amabhethri libiza ngaphezu kwanoma yiliphi ibhethri.
• Gcina ikhithi elilodwa lokunikela. Beka ikhithi elilodwa eliyoba umthombo wama-spare ukuze amakhithi ayisikhombisa asebenzayo ahlale ephelele esikhundleni samakhithi ayisishiyagalombili ngalinye lawo liswele ingxenye.
• Yiba nesifundo sesilingisi silungile. Isilingisi samahhala esisebenza esipheqululini esinjenge-sheen verse sisebenzisa i-MicroPython yangempela kumarobhothi angokoqobo ngaphandle kwe-hardware nangaphandle kokufaka izinhlelo. Gcina isifundo esisodwa sesilingisi silungiselelwe iyunithi ngayinye bese ukuhluleka kwe-hardware kuyeka ukuba yizimo eziphuthumayo. Ungasivivinya ngemizuzu embalwa ku-/verse-try/en-us.

Indlela esibhekana ngayo nalokhu ku-sheen

Iqiniso eliphelele kuqala: i-hardware yethu nayo iyaphuka emakilasini. Kwenzeka kuyo yonke into. Umehluko esiwuhlosayo ukulungiseka kwempahla. Yonke inzwa nawo wonke ama-spare e-sheenbot∞ adayiswa ngayinye esitolo sethu, athunyelwe yonke indawo eNingizimu Afrika, ngakho akukho ukuthumela okuvela phesheya noma isandiso sezintela zasemngceleni, futhi inzwa efile ishintshwa ngemodyuli oyixhumayo isebenze ebiza amarandi ambalwa esikhundleni sokushintsha ikhithi lonke. Iwekhishophu yethu yaseKapa yenza ukulungisa nezingxenye ezenziwe ngokwesifiso. Ezikoleni eziqala phansi, ukuthengwa nokufakwa kwelebhu kufaka phakathi konke ukuhlonywa okuhlanganisa nokuqeqeshwa kothisha, kanti sheen verse imahhala esipheqululini njengecebo elisekelayo elingadingi i-hardware.

Imibuzo Evame Ukubuzwa

Ingabe ama-motor asemakhithini e-robotics ayizinto eziphelayo ngempela?

Okungenani umthengisi omkhulu oyedwa usewaphatha ngaleyo ndlela. Engxoxweni ye-VEX Forum kaMashi 2024, uthisha owaphukelwa ama-motor phakathi namasonto ayishumi wenqatshelwa isicelo sewaranti ngoba abasekeli babeka ama-motor esigabeni sezinto eziphelayo. Noma ngabe uthenga kumuphi umthengisi, thola impendulo yakhe ebhaliwe kulowo mbuzo ngqo ngaphambi kokuba ukhokhe.

Isikole kufanele sabele malini kuma-spare e-robotics?

Alikho izinga elishicilelwe, kodwa lawa manani angempela angenhla ayethusa: ama-motor ama-4 kwangama-32 (12.5%) ahluleka emasontweni ayishumi okuqala ekilasini elilodwa. Umthetho osebenzayo ukubala intengo yesethi ephelele yama-motor, izintambo namaphakethe amabhethri okushintsha impahla yakho yonke bese uyifaka esabelweni somnyaka wokuqala, futhi uhlole intengo yengxenye eyodwa ngaphambi kokukhetha umthengisi, hhayi emva kwalokho.

Yini ebulala amabhodi okulawula e-robotics emakilasini?

Okuvame ukusolwa ukukhishwa kukagesi omile, izixhumanisi eziqhephukile nezingozi zamabhethri. Iqembu elilodwa le-FTC labika ukulahlekelwa ama-hub okulawula amathathu ngonyaka owodwa ngenxa kagesi omile kuphela. Imikhuba eyisisekelo yokuvikela ugesi omile, ukuthinta insimbi kuqala, ukugcina amabhodi esesikhwameni, nokuqhelelana nekhaphethi, akubizi lutho futhi kususa indlela yokuhluleka ebiza kakhulu kunazo zonke.

Ngingabavimba kanjani abafundi ekulahleni nasekwephuleni izingxenye?

Phatha ilebhu njengomtapo wolwazi. Nika ikhithi ngalinye inombolo, wenze abafundi basayine lapho bethatha nalapho bebuyisa amakhithi, bese uqeda isifundo ngasinye ngokubala izingxenye imizuzu emibili. Othisha babika ukuthi ukugcinwa kwempahla okungalawulwa kuholela ekulahlekeni okuqhubekayo kwempahla, ngakho uhlelo lokubhalisa ukuphuma nokungena lubaluleke njengokukhetha i-hardware.

Ngingakwazi yini ukuqhuba isifundo se-robotics uma amakhithi ephukile?

Yebo, uma ulungiselele isilingisi ongabhekela kuso. Izilingisi zamahhala zesiphequluli zisho ukuthi inhloso yesifundo iyasinda ngisho noma i-hardware ingasindanga. I-sheen verse isebenzisa i-MicroPython yangempela kumarobhothi alingisiwe ngaphandle kokufaka lutho, futhi ungayizama mahhala ku-/verse-try/en-us. Gcina inguqulo eyodwa yesilingisi yeyunithi ngayinye ilungile bese amakhithi aphukile ayeka ukukubiza izinsuku zokufundisa.
