Uma abazali nabaholi bezikole belunguza ekilasini lamarobhothi, imvamisa babona izingane zihlanganisa izinhlaka zepulasitiki, zifaka izintambo zejampha, futhi zibuka umshini omncane uhamba etafuleni. Umbono olula uthi lezi zingane zifunda “ukwakha irobhothi” noma zilungiselela umsebenzi oqondene ngqo ne-mechatronics.

Iqiniso lisebenza kakhulu kunalokho. Ingane esekilasini lamarobhothi empeleni ifunda ukuthi ingaxoxisana kanjani nezwe eliphathekayo isebenzisa umqondo onengqondo. Ezweni lapho isofthiwe iya ngokuya ingabambeki ngezandla, amarobhothi angesinye sezifundo ezimbalwa lapho umqondo ongalungile unemiphumela esheshayo, ephathekayo: irobhothi lishayisa odongeni, lizungeze indilinga, noma lenqabe nokunyakaza nhlobo.

Ukuze siqonde ukuthi kufundwani ngempela, kumele sidlule emagameni okukhangisa anjengokuthi “amakhono ekhulu lama-21” sibheke izindawo zangempela zokungqubuzana ephrojekthini. Ake sihambe nenselele evamile yamarobhothi—ukwakha irobhothi elilula elilandela umugqa—sibheke ikhono elidluliselekayo elitholakala kukho konke ukukhubeka.

Ukukhubeka: Inzwa Ifunda Umsindo

Ukuze lilandele umugqa omnyama phansi okumhlophe, irobhothi lisebenzisa izinzwa ze-infrared (IR) ezibona ukukhanya okuphindisiwe. Umbono ongenalwazi uthi okumnyama kuzohlala kufundeka njengenani eliphansi (ake sithi, 10) bese okumhlophe kufundeka njengenani eliphakeme (ake sithi, 90).

Iqiniso: Ikilasi liqala ngo-14:00. Sekuyi-15:00, ilanga lantambama likhanya ngqo ngefasitela lekilasi. Ngokuzumayo, phansi “okumhlophe” kufundeka ngendlela ehluke ngokuphelele ngenxa yokukhanya kwe-infrared okuvela elangeni. Noma, izibani ze-fluorescent zesikole ziyaphazima ngesivinini esiphazamisa inzwa. Irobhothi lizungeza lingasalawuleki.

Ikhono Langempela: Ukukalibhula Nokulinganisa Idatha. Umfundi akakwazi nje ukubhala inombolo eyodwa engaguquki ngaphakathi ohlelweni lwakhe. Kumele afunde ukukalibhula izinzwa zakhe ngokuguquguqukayo, ethatha izibalo zendawo emzungezile ekuqaleni kokusebenza abese ebala umkhawulo ohambisana naleyo ndawo. Bafunda ukuthi idatha yezwe langempela inomsindo, ayihambisani, futhi incike esimweni. Lesi yisisekelo sesayensi yedatha, ukucubungula amasignali, nokucabanga ngezibalo.

Ukukhubeka: Irobhothi Lidlula Endaweni

Uma izinzwa sezikwazi ukubona umugqa, umfundi uhlela ama-motor ngesitatimende esilula sengqondo: “Uma ubona okumnyama, phendukela kwesobunxele; uma ubona okumhlophe, phendukela kwesokudla.”

Iqiniso: Irobhothi alilandeli umugqa kahle. Esikhundleni salokho, liqala ukunyakazela ngamandla libuyela emuva naphambili, lidlidlizela njengomshini wokuwasha osemzuliswaneni wokuqhamula, bese ekugcineni lilahlekelwa umugqa ngokuphelele libe seliya ngaphansi kwekhabethe. Lokhu “ukuhamba komuntu odakiwe” okwaziwayo kwezinhlelo ezilula zempendulo.

Ikhono Langempela: Ithiyori Yokulawula Nemizuliswano Yempendulo. Umfundi uthola ukuthi izinqumo ezimbili nje (vula/vala) ziholela ezinhlelweni ezingazinzile, ezilungisa ngokweqile. Ukulungisa lokhu, kumele adlulele ekulawuleni okulinganiselayo—okwenza i-engeli yokuqondisa ilingane nokuthi irobhothi liphambuke kangakanani phakathi nendawo. Bafunda ukuphatha ukubambezeleka, amandla okuqhubeka, nokuzenqena kohlelo. Lona umqondo ofanayo ncamashi osetshenziswa kuma-thermostat ezimboni, ezinhlelweni ze-autopilot, nasekulungisweni kokwehla kwamandla emali.

Ukukhubeka: Ukufa Kohlelo Lonke

Irobhothi belisebenza kahle emizuzwini emihlanu edlule. Manje, alinyakazi nhlobo.

Iqiniso: Ethukile, umfundi ulingeka ukuthi ashintshe izinto ezintathu ngasikhathi sinye: abhale kabusha ikhodi, ashintshe amabhethri, afake izintambo kwamanye ama-port. Irobhothi lisengasebenzi, futhi manje akekho owaziyo ukuthi kungani, ngoba isisekelo sokuqhathanisa selilahlekile.

Ikhono Langempela: Ukwehlukanisa Okuguqukayo (I-debugging). Endaweni ehlelekile, sifundisa abafundi ukuthi baphathe irobhothi elifile njengocwaningo lwesayensi. Kumele bahlole umbono owodwa ngesikhathi. Ingabe ibhethri likhipha i-voltage efanele? (Hlola nge-multimeter). Ingabe i-microcontroller ithola ugesi? (Hlola i-LED esebhodini). Ingabe ikhodi iyasebenza ngempela? (Faka isitatimende esilula sokuphrinta nge-serial). Kuphela uma okukodwa okuguqukayo sekususiwe yilapho bedlulela kokulandelayo. Lokhu kucwaninga okunesiyalo kuyinhliziyo yanoma yimuphi umsebenzi wobunjiniyela, wezokwelapha, noma wokuxilonga.

Ukukhubeka: Umkhawulo Wekhithi Esetshenziswa Ndawonye

Ekilasini elivamile laseNingizimu Afrika, abafundi babelana ngamakhithi. Iqembu labafundi abathathu lingase libe ne-microcontroller eyodwa, uhlaka olulodwa, nelaptop elilodwa abazokwabelana ngalo esikhathini semizuzu engu-45, okuvame ukuxakwa nangosongo lokucishwa kukagesi endaweni.

Iqiniso: Omunye umfundi ufuna ukwengeza ingalo yomshini; omunye ufuna ukusheshisa ama-motor; owesithathu uzama ukulungisa isondo elixegayo. Ngaphandle kokuxhumanisa, babhala phezu kwekhodi yomunye nomunye futhi badilize umsebenzi womunye nomunye ngokoqobo.

Ikhono Langempela: Ukuphathwa Kwezinsiza Nesikweletu Sobuchwepheshe. Bafunda ukuthi imikhawulo yokwakhiwa okuphathekayo inciphisa izinketho zesofthiwe, kanjalo nangokuphambene. Kumele babhale phansi imidwebo yezintambo zabo futhi babhale ikhodi ecacile, enamazwana ukuze umlingani wabo ayiqonde uma beshintshana ngezindima. Bafunda ukuxoxisana, ukwaba umsebenzi, nokuphatha impahla yobuchwepheshe abelana ngayo ngaphansi kwesikhathi esincane.

Ukuhunyushelwa Kwezemfundo

Uma sihumusha lezi zinselele zansuku zonke zasekilasini zibe yimiphumela yemfundo, umehluko phakathi kwenkulumo yokukhangisa nokufunda kwangempela kwezobuchwepheshe uyacaca:

Yingakho sigxila kakhulu kulezi zindawo zokungqubuzana ohlelweni lwethu lwezifundo. Kungakhathaliseki ukuthi ingane iya esifundweni sokuzama samahhala e-akhademi yethu yaseKapa noma isebenza ngohlelo lwethu oluthuthukile lwezifundo lwe-Infinity, asingeneli ukuze siyilungisele irobhothi. Ukufunda akukho erobhothini elisebenzayo; ukufunda kusekuzabalazeni ukuze lisebenze.
