Kusuka ku-LEGO kuya ku-FTC: Okudingeka ngempela ukuze izikole zaseNingizimu Afrika zeqe
Ukusuka kumarobhothi e-LEGO uye ku-FIRST Tech Challenge akusona isinyathelo esincane—kungukweqa okukhulu kwesakhiwo nakwezobuchwepheshe. Nakhu okubizayo, okuzophuka, nendlela yokusinda kulolu shintsho.
Uma isikole sakho sesineminyaka embalwa siqhuba amaqembu e-LEGO Mindstorms noma e-SPIKE Prime, cishe usufike ophahleni. Abafundi bakho abadala bangakha umshini olandela umugqa belele, sebediniwe yizikhonkwane zepulasitiki, futhi sebebheke i-FIRST Tech Challenge (FTC).
Asethembeke ngokugcwele: ukudlulela ku-FTC usuka ku-LEGO akusona isinyathelo esiya phezulu esitebhisini. Kungukweqela ngaphesheya kwesihosha. Ukushiya ipulasitiki elihlanganiswa ngokugxumeka uye kumachaneli ensimbi, izingxenyekazi zikagesi zezinga lezimboni, kanye nokuhlela nge-Java okusekelwe embhalweni, kudinga ushintsho olujulile kwisabelomali, kwisikhala nakwindlela yokufundisa.
Uma uphatha i-FTC njenge“LEGO enkulu”, iqembu lakho lizogcina linenqwaba ebizayo yezikulufu ezishayekile, amabhethri afile nabafundi abakhathele. Kodwa uma uzilungiselela umehluko wesakhiwo, kungumsebenzi wobunjiniyela onenzuzo enkulu kunayo yonke isikole samabanga aphakeme esingayinikeza abafundi. Nakhu okudingeka ngempela ukuze weqe.
Igebe Lezobuchwepheshe: Ipulasitiki Kubhekene Nensimbi
I-LEGO yakhelwe ukuthi ihluleke ngendlela ephephile. Uma igiya libambeka, i-clutch iyashelela noma imoto ime ingashi. Uma isakhiwo sibuthakathaka, siyagoba noma siphuke ngaphandle kokulimaza.
Amarobhothi e-FTC yimishini esindayo, ehamba ngesivinini, eyenziwe nge-aluminium nangensimbi, iqhutshwa yizimoto ze-matrix zamavolthi angu-12. Uma kukhona okungahambi kahle lapha, kwephuka unomphela. Ama-axle ayashayeka, amagiya ayanqamuka, futhi amabhokisi amagiya ezimoto ayabhidlika ngaphansi kwe-torque ephezulu.
Abafundi bakho kuzodingeka bafunde imigomo yangempela yobunjiniyela bemishini:
- Ukwakha okusekelwe ephethini: Uzodlulela kuzinhlelo zezakhiwo ezifana ne-GoBILDA noma i-REV Robotics. Lezi zisebenzisa amaphethini athile egridi (njengegridi lama-8mm) futhi zidinga okhiye be-hex, ama-locknut, kanye noketshezi lokukhiya izintambo ukuze izinto zingaxegi ngenxa yokudlidliza.
- Ukuzenzela izingxenye: Ngokungafani ne-LEGO, i-FTC ivumela izingxenye ezenziwe ngokwezifiso. Amaqembu aphumelelayo abona ngokushesha ukuthi adinga ama-bracket aphrintwe nge-3D, amapuleti e-acrylic asikwe nge-laser, noma ama-flap okungenisa e-polycarbonate enziwe ngomshini ukuze ahlale eqhudelana.
- Ifiziksi eqinile: Irobhothi elingu-15kg elihamba ngamamitha angu-2 ngomzuzwana linamandla amakhulu okuhamba. Amaqembu kumele akhele ukushayisana, ukuqina kwesakhiwo, nendawo emaphakathi yesisindo.
Uhlelo Lokulawula Nokushintsha Kwesofthiwe
Ku-LEGO, “ubuchopho” yi-hub eyodwa exhuma ngqo kwilaptop nge-Bluetooth noma nge-USB. Ukuhlela imvamisa kwenziwa ngamabhulokhi asekelwe ku-Scratch.
Uhlelo lokulawula lwe-FTC luyinethiwekhi yamadivayisi amabili. Irobhothi lilawulwa yi-REV Control Hub (empeleni yikhompyutha ye-Android eqhuba amachweba akhethekile okungena nokuphuma). Lokhu kuxhumana ngoxhumano lwe-Wi-Fi Direct olukhethekile nesi-Driver Station—okungaba yidivayisi yesibili ye-Android noma isilawuli esiphathwayo esikhethekile—esixhunywe kuma-gamepad amabili e-USB.
Lesi sakhiwo siletha izinkinga zangempela ze-IT. Endaweni evamile yesikole saseNingizimu Afrika, amanethiwekhi e-Wi-Fi yesikole e-WPA2-Enterprise azovimba noma aphazamise amasiginali e-Wi-Fi Direct. Iqembu lakho kuzodingeka lifunde ukuphatha amachaneli e-wireless, ukuxazulula ukukhishwa kukagesi ongagelezi okuqandisa amamojula e-USB, nokuphatha ukubuyekezwa kwe-firmware kumadivayisi amaningi.
Ngasohlangothini lwesofthiwe, nakuba ukuhlela ngamabhulokhi kungenzeka ku-FTC, kuwumgwaqo ovalekile emaqenjini aqhudelanayo. Ukuze bathole okuningi kuma-sensor, kuma-encoder nakuzisekelo zokushayela eziyinkimbinkimbi (njengamasondo e-Mecanum), abafundi kumele babhale i-Java yangempela. Kuzodingeka badlulele ekubhaleni ikhodi ngombhalo, ekulawuleni izinguqulo ngo-Git, nakuzindawo zokuthuthukisa ezihlanganisiwe (ama-IDE) ezifana ne-Android Studio.
Ukuqhathanisa Izinhlelo Zombili
Ukuze uqonde ubukhulu balolu shintsho, cabanga ngokuthi lezi zinkundla ezimbili ziqhathaniseka kanjani ngokoqobo:
| Isici | I-LEGO Robotics (FLL) | I-FIRST Tech Challenge (FTC) |
|---|---|---|
| Impahla Eyinhloko | Ipulasitiki i-ABS (i-LEGO engenazikhonkwane) | Amachaneli e-aluminium, ama-shaft ensimbi, okuphrintwe nge-3D ngokwezifiso |
| Ukuhlela | Amabhulokhi e-Scratch / i-Python elula | I-Java (nge-OnBot Java noma nge-Android Studio) |
| Ama-actuator | Kufika kuzimoto ze-servo ezingu-4 eziphakathi noma ezinkulu | Kufika kuzimoto ze-DC ezingu-8 ze-torque ephezulu + izimoto ze-servo ezingu-12 |
| Umthombo Wamandla | Ibhethri elincane le-Li-ion elishajekayo | Iphakethe lebhethri elizacile le-NiMH noma le-LiFePO4 lama-12V |
| Indawo Yokusebenza Edingekayo | Ideski elivamile lekilasi | Ibhentshi lewekshophu elizinikele nenkundla engu-3.6m x 3.6m |
| Izindleko Zokungena Ezivamile | R9,000 - R12,000 | R45,000 - R80,000 (kufaka izingxenyekazi zikagesi & amathuluzi) |
Amaqiniso Esimo SaseNingizimu Afrika
Ukuqhuba iqembu le-FTC eNingizimu Afrika kuletha izithiyo zendawo ezithile okumele uzihlelele:
- Ukucishwa kukagesi: Ngokungafani nama-hub e-LEGO angashaja ngeshaja yefoni, i-FTC isebenzisa amabhethri asindayo angama-12V. Amashaja adinga ugesi ozinzile futhi athatha amahora ukulinganisa amaseli. Uma isikole sakho singenayo i-inverter noma isipele selanga, ukucishwa kukagesi okuzumayo ngesikhathi seseshini yokwakha kungayimisa ngaso leso sikhathi imihlolo.
- Amaketango Okuhlinzeka: Awukwazi ukungena esitolo sezingane sasendaweni uyothenga i-GoBILDA dual-block mount noma i-hub ye-REV esikhundleni sedala. Cishe yonke i-hardware ekhethekile ye-FTC ithengwa ngaphandle kwezwe. Uma ushayeka igiya elibalulekile ngesonto ngaphambi komqhudelwano kazwelonke, awukwazi ukuthola kalula esinye lapha ekhaya. Kumele ufunde ukugcina isitoko sezingxenye ezisele.
- Isabelomali: Isizini yokuqala yokuqhudelana idinga imali eningi yokuqalisa. Phakathi kwekhithi yokuqala, izingxenyekazi zokulawula, ama-gamepad, amathuluzi nezimali zokubhalisela umqhudelwano, ubheke isabelomali sokuqala esingaphansi kuka-R50,000.
Uma uzama ukuthola ukuthi yiziphi ngempela izingxenye okumele uzi-ode ukuze ungangenisi izinto ezingafanele, ungabheka i-Sheen Robotics Store esiyihlelile, lapho sigcina khona izingxenyekazi namakhithi asemthethweni emqhudelwaneni atholakala lapha ekhaya, ukuze ugweme inkinga yezempahla engenayo ezweni.
Uhlelo Lokushintsha Isinyathelo Ngesinyathelo
Uma isikole sakho sesikulungele ukweqa, ungazami ukwenza konke ngenyanga eyodwa. Sincoma indlela eyenziwa ngezigaba phakathi nonyaka wonke wezemfundo.
Isigaba 1: Unyaka Wokuxhumanisa
Ungawabeki eceleni amakhithi akho e-LEGO okwamanje. Ngenkathi abafundi bakho abadala beqeda isizini yabo yokugcina ye-FLL, bethule ekuhleleni okusekelwe embhalweni. Baphoqe ukuthi bahlele amarobhothi abo e-LEGO ngePython esikhundleni samabhulokhi. Lokhu kubafundisa isakhiwo solimi lokuhlela olugxile ezintweni, ngaphandle kobunzima be-hardware ye-FTC.
Isigaba 2: Ukuzihlomisa Ngamathuluzi
Ngaphambi kokuthenga irobhothi, thenga amathuluzi. Iqembu le-FTC lidinga indawo yokusebenza ezinikele. Uzodinga ama-hex driver e-metric (ikakhulukazi angu-1.5mm, 2.0mm no-2.5mm), izipanela ezihlanganisiwe, isaha lensimbi noma ithuluzi elijikelezayo lokusika ama-shaft, i-multimeter yedijithali, kanye nephrinta le-3D eliyisisekelo lokwenza izinto zokubopha ngokwezifiso.
Isigaba 3: Ukwakha Uhlaka
Qala ngekhithi ye-drivetrain esivele iqinisekisiwe kunokuklama kusukela ekuqaleni. Ukwakha isisekelo esilula sokushayela se-Mecanum samasondo amane usebenzisa ikhithi yezingxenye kuvumela abafundi ukuthi baqonde indlela esebenza ngayo iketango, ibhande noma amagiya, ngaphambi kokuba bazame ukuklama izindlela eziyinkimbinkimbi zokungenisa noma zokuphakamisa.
Ezikoleni ezifuna isiqondiso esihleliwe kulolu shintsho, sinikeza ukuqeqeshwa kokwenza ngezandla nezinhlelo zokweluleka ezenzelwe ngqo ukusiza othisha ukuthi bawele leli gebe ngokuphepha, ku-Sheen Robotics FTC Support.
Isinqumo: Kuyakufanela Yini?
Yebo, ukufunda kunzima, futhi yebo, isizini yokuqala izozwakala iyisiphithiphithi. Kodwa inzuzo yemfundo ayiqhathaniseki nalutho.
Uma umfundi ephumelela ukuhlela indlela ezizimele esebenzisa i-localization ye-road-runner, noma eklama indlela yakhe yokungenisa ayiphrinte ngokwakhe nge-3D, akasadlali ngamathoyizi emfundo. Wenza ubunjiniyela bangempela, obusezingeni lezimboni. Uma isikole sakho sinendawo, sinesabelomali futhi sinomeluleki ozimisele ukufunda kanye nabafundi, ukweqela ku-FTC kungukutshala imali okungcono kakhulu ongakwenza emnyangweni wakho we-STEM.
