Koj puas tau xav ua qee yam koj tus kheej uas tuaj yeem xa mus rau qhov chaw thiab ntsuas qhov kub ntawm lwm lub ntiaj teb? Hauv peb chav kawm physics hauv Tsev Kawm Ntawv Qib Siab, peb nyob qhov twg raug txib los tsim CubeSat nrog kev ua haujlwm arduino nrog cov lus nug tseem ceeb Peb tuaj yeem ua haujlwm li cas hauv Mars? Peb txiav txim siab kom nws ntsuas kub ntawm lub ntiaj chaw, vim tias leej twg tsis xav paub seb huab cua sov li cas? Txawm li cas los xij, peb yuav tsum ua kom nws tawm ntawm qee yam pheej yig, tab sis kuj tseem ruaj khov. Yog li ntawd, peb siv Legos. Qhov no ua rau CubeSat ruaj, thiab pab peb mus txog qhov loj me me zoo nkauj yooj yim-txawm tias txhua daim nyob qhov twg pesky me ntsis! Peb lub hom phiaj yog kom muaj lub ntsej muag ua haujlwm tau zoo uas tuaj yeem ntsuas kub ntawm ib puag ncig, thiab tiv thaiv CubeSat nyob ib puag ncig nws.

Kauj Ruam 1: Sau Cov Khoom Siv/kos duab CubeSat

Thawj qhov koj yuav xav ua yog kos duab CubeSat. Koj yuav tsum muaj lub tswv yim ntawm yam koj xav tsim ua ntej koj tsim nws. Ib qho ntawm cov duab saum toj no yog CubeSat cov duab kos uas peb tau ua. Tom ntej no, sau koj cov ntaub ntawv. Txog CubeSat peb tab tom tsim, peb siv Legos. Peb tau xaiv Legos vim tias lawv yooj yim kom tau txais thiab muab tso ua ke, thiab tib lub sijhawm lawv ua tau ntev thiab yuav ua tiav cov haujlwm uas xav tau zoo. Yog li, koj yuav tsum tau txais qee yam Legos. tau ob peb daim dav dav, uas yog 10cm X 10 cm X 10 cm, lossis ob peb daim hauv paus uas tuaj yeem muab tso ua ke rau ntawm 10 txog 10 daim. Rau peb CubeSat, peb yuav tsum tau txais ntau daim hauv paus thiab muab tso ua ke kom ua 10 cm los ntawm 10 cm puag. Koj kuj tseem yuav tsum tau txais Legos los ua lub ru tsev ib yam nkaus. Tom qab koj tau txais cov Legos, koj yuav tsum tau txais ib tuj ntawm Legos me me los txhim kho phab ntsa ntawm CubeSat. Xyuas kom cov Legos no yuag yuag, yog li lawv tsis siv ntau dhau ntawm sab hauv ntawm CubeSat.

Kauj Ruam 2: Tsim Cubesat

Ua ntej, peb tsim qhov zoo nkauj 10x10x10. Nws coj ntau qhov sib txawv tsim. Ua ntej peb muaj lub txee nyob hauv nruab nrab tab sis tom qab peb txiav txim siab tias tsis tsim nyog muaj. Yog tias koj xaiv kom muaj lub txee nyob hauv nruab nrab, Kuv xav kom tsuas yog ib lub txee vim tias koj yuav tsum tau muab nws sib nrug txhua zaus koj tso rau hauv thiab tshem tawm koj li Arduino thiab lub ntsuas. Peb tau ntxiv lub qhov rais me me kom peb tuaj yeem saib nrawm sab hauv thaum lub hau kaw tau kaw kom peb tuaj yeem pom txhua yam ua haujlwm tau zoo. Txhawm rau CubeSat ruaj khov dua, peb muab ob txheej Lego tso rau hauv qab. Qhov ruaj khov dua qhov zoo dua, vim tias CubeSat no yuav tsum muaj peev xwm muaj sia nyob ntau yam teeb meem sib txawv.

Kauj Ruam 3: Txuas thiab Coding Arduino

Cov kauj ruam thib ob ntawm txoj haujlwm no yog qhov uas koj yuav tsum tau xaim xov tooj cua arduino. Cov kauj ruam no tseem ceeb heev, vim tias, yog tias qhov no ua tsis tiav ces lub voos xwmfab zaum yuav tsis tuaj yeem nyeem qhov ntsuas kub. Txhawm rau ua kom tiav txoj hlua ntawm arduino, koj yuav xav tau qee cov ntaub ntawv. Cov ntaub ntawv no yog roj teeb, arduino, daim npav SD, xov hlau txuas, lub khob cij, ntsuas kub, thiab khoos phis tawj. Lub khoos phis tawj yuav siv los saib seb cov xov hlau ua haujlwm raug. Nov yog lub vev xaib uas tau pab tau zoo hauv kev coj peb li cas los xaim xov tooj cua arduino:

create.arduino.cc/projecthub/TheGadgetBoy/…

Cov duab thiab daim duab fritzing saum toj no tuaj yeem pab koj ib yam. Cov lej ntawm arduino tseem yuav raug kuaj hauv lub computer kom pom tias nws ua haujlwm. Yog tias txhua yam ua haujlwm, tom qab ntawd lub arduino tuaj yeem tshem tawm ntawm lub khoos phis tawj, thiab npaj mus.

Kauj Ruam 4: Txheeb Xyuas Cubesat

Tam sim no tias CubeSat, tus lej, thiab txuas ntawm Arduino tau ua tiav, koj yuav tau sim ntsuas sai. Yog tias qhov kev sim no ua tsis tiav, koj CubeSat tuaj yeem muaj peev xwm ua kom puas tag nrho, nrog rau koj Arduino. Yog li, koj yuav xav paub tseeb tias koj Arduino tau npaj rau qhov no. Ntawd yog qhov uas cov kauj ruam no los ua si, txheeb xyuas CubeSat. Ua ntej, koj yuav tsum tso koj Arduino ruaj ntseg sab hauv CubeSat, thiab paub tseeb tias nws yuav tsis jiggle ib ncig. Tom qab ntawd, koj yuav tsum ua kom ntseeg tau tias txhua daim ntawm CubeSat tau nyab xeeb nyob hauv qhov chaw. Yuav tsis muaj cov xoob xoob, lossis CubeSat yuav zoo dua tuaj sib nrug thaum kuaj. Yog tias koj ua tib zoo tshuaj xyuas koj li CubeSat, tom qab ntawv qhov kev xeem nws dhau mus yuav tsum dhau mus yooj yim.

Kauj Ruam 5: Ua Kom CubeSat

Cov kauj ruam no yuav yog npaj rau thawj qhov kev sim CubeSat yuav dhau mus. Hauv qhov kev sim, CubeSat yuav raug viav vias ncig ntawm qhov nrawm nrawm hauv lub voj voog rau 30 vib nas this. Koj yuav tsum tau ua kom ntseeg tau tias CubeSat tau nruj nruj kom nws tsis ya tawm. Peb khi 2 txoj hlua nyob ib puag ncig CubeSat, thiab khi lawv nruj. Tom qab ntawd, peb tau ntxiv lwm txoj hlua ntev, uas tau khi nyob ib ncig ntawm thawj ob qho. Peb tau khawm txoj hlua no ntau zaus nyob rau sab saum toj thiab hauv qab yog li nws muaj kev nyab xeeb li sai tau. Qhov no yuav siv ntau qhov kev sim vim tias koj xav ua kom txoj hlua zoo tag li nws yuav tsis xoob thaum ya dav hlau.

Kauj Ruam 6: Kev Xiav Viav Vias

Rau kev nyab xeeb hauv cov kauj ruam no, nco ntsoov hnav tsom iav los tiv thaiv koj lub qhov muag. Hauv cov kauj ruam no, koj yuav tau khiav CubeSat los ntawm kev sim seb nws puas tiv thaiv Arduino zoo txaus rau nws ua nws txoj haujlwm (nrhiav kub). Thawj qhov kev xeem yog qhov uas xav tau txoj hlua. Hauv qhov kev sim no, Arduino yuav raug swung ncig (raws li qhia hauv daim duab/vis dis aus saum toj no)- (qee zaum cov vis dis aus muaj teeb meem thauj khoom). Tus qauv Mars yuav raug muab tso rau hauv nruab nrab. Txhawm rau ua tiav qhov kev xeem no, Arduino yuav tsum tau tig mus ncig yam tsis muaj kev cuam tshuam, uas yog vim li cas nws thiaj li yuav tsum tau tuav kom zoo, thiab lawv Arduino yuav tsum tau ua haujlwm zoo tom qab qhov kev xeem tiav. Tias yog vim li cas koj yuav tsum paub tseeb tias Arduino tau nyab xeeb zoo hauv CubeSat.

Kauj Ruam 7: Xeem #2- Kev Sib Ntsib

Hauv cov kauj ruam no koj CubeSat yuav dhau qhov kev xeem #2. Qhov kev xeem no yog kev xeem co. Hauv qhov kev sim no, CubeSat yuav muab tso rau hauv lub yas dhos raws li qhia hauv daim duab/vis dis aus (qee zaum cov vis dis aus muaj teeb meem thauj khoom) saum toj no thiab yuav tshee hnyo rov qab los rau 30 vib nas this. Txhawm rau kom dhau qhov kev xeem no, koj CubeSat thiab Arduino tseem yuav tsum tau ua haujlwm zoo tom qab lawv tshee hnyo.

Kauj Ruam 8: Cov txiaj ntsig/Ua tiav Kub CubeSat

Thaum kawg, peb CubeSat tuaj yeem ua tiav qhov ntsuas kub thaum mus dhau txhua qhov kev sim. Cov ntaub ntawv nyeem tas li nyeem 26-30 degrees Celsius hauv txhua qhov kev xeem. Qhov no zoo ib yam li 78-86 degrees Fahrenheit. Txawm li cas los xij, peb tau ntsib qee qhov teeb meem ntawm txoj kev. Piv txwv li, ntau zaus cov lej ntawm arduino tsis ua haujlwm, thiab nyeem 126 degrees Celsius. Nws tau siv ntau qhov kev sim ua kom tiav qhov ntsuas kub kom raug. Qee qhov lus qhia kuv yuav muab rau ib tus neeg ua txoj haujlwm no yuav yog sim ntau yam kev hloov pauv ntawm cov cai thiab thaiv, thiab kom ntseeg tau tias koj cov arduino haum nruj rau hauv CubeSat. Koj yuav tsum tau ua kom nruj qhov sib txawv sab hauv CubeSat kom ntseeg tau tias cov arduino haum zoo hauv. Peb muaj qee qhov teeb meem nrog arduino tau xoob heev hauv CubeSat.

Hauv txoj haujlwm no, koj tseem yuav tsum tau siv koj qhov kev paub txog physics. Kev paub txog kev siv tshuab, lub zog, thiab lub zog yuav tsum tau siv thoob plaws hauv txoj haujlwm. Thoob plaws hauv txoj haujlwm peb tau kawm paub ntau ntxiv txog lub hnub ci, thiab thev naus laus zis tshiab zoo li CubeSats. Peb kuj tau kawm txog kev siv lub zog nqus, thiab yuav ua li cas lub zog no yuav cuam tshuam CubeSat. Ib lub ntsiab lus tseem ceeb heev nrog txoj haujlwm no yog kev tshaj tawm satellite. Peb tau kawm txog kev txav mus los ntawm lub hnub qub los ntawm kev siv nrawm, nqa lub zog, thiab lub ntiajteb txawj nqus. Qhov no yuav pab peb nrhiav cov projectiles ntawm lub hnub qub.

Thaum koj CubeSat thiab arduino ua tiav qhov kev xeem tiav, thiab ua haujlwm tau zoo, koj ua tiav. Koj CubeSat yuav tsum muaj peev xwm muaj sia nyob ntawm huab cua ntawm Mars. Nco ntsoov tias lub ntsuas ntsuas tau ua tiav qhov ntsuas kub thoob plaws qhov kev sim ib yam. Koj CubeSat tau npaj txhij mus rau qhov chaw!
