QHIA

BEND_it yog lub tshuab ntsuas nrawm nrawm me me. Nws zoo nkauj heev ntawm khoov thiab tsoo yam. Nws kuj tseem tuaj yeem siv tau rau lub sijhawm. Nws tuaj yeem pab ib tus khaws cov ntaub ntawv zoo li:

1. Kab rov tav zog quab yuam vim kev ua arching.
2. Hloov hauv Kev Khoov Kev Nyuaj Siab vim kev hloov pauv hauv geometry.
3. Khoom Nyuaj

Txoj Haujlwm tau ua tiav los ntawm Anand Shah thiab Ryan Daley raws li ib feem ntawm Chav Kawm Seminar: Kev Tsim Kho Tshuab thiab Kev Tsim Kho Digital ntawm ITECH program, University of Stuttgart, Germany.

Khoom siv

Txoj haujlwm tau xeeb tub thaum muaj kev nyuaj siab COVID-19 lub sijhawm thiab yog li ntawd tuaj yeem ua tiav hauv tsev yam tsis tas yuav siv Laser-txiav ntu/ 3D Luam ntu lossis lwm yam khoom siv rhiav.

KEV NTSEEG

Stepper Tsav

28BYJ-48 yog 5-hlau uni-polar stepper lub cev muaj zog uas txav tau 32 cov kauj ruam hauv ib qho kev sib hloov sab hauv tab sis muaj cov kab ke ua haujlwm uas txav tus ncej los ntawm qhov zoo ntawm 64. Qhov tshwm sim yog lub cav uas tig ntawm 2048 cov kauj ruam ib zaug. Txhawm rau tswj lub cav thiab cia nws ua haujlwm zoo peb yuav ULM 2003 Darlington Transister Array. Yog xav paub cov ntaub ntawv ntxaws ntxaws, lub vev xaib hais los no yog cov peev txheej zoo:

Load Cell

Rau txoj haujlwm peb tab tom siv 1 kg Load cell nrog HX711 ntsuas lub ntsuas. Load cells yog cov hlau uas muaj cov ntsuas ntsuas txuas rau nws. Ntsuas ntsuas ntsuas yog cov tshuaj tiv thaiv tsis haum, nws qhov kev tiv thaiv sib txawv raws li lawv tau hloov pauv. HX711 microchip nthuav tawm qhov kev tiv thaiv no thiab hloov nws mus rau Arduino Board. Load cell yuav tsum tau ntsuas ua ntej nrog paub qhov hnyav. ntawm no hauv peb cov ntaub ntawv ntsuas tau ntsuas hauv kg thiab tom qab ntawv tus lej lej sib npaug 9.8 kom tau txais kev quab yuam hauv Newtons. Kom tau txais xov xwm ntau ntxiv koj tuaj yeem tshawb xyuas cov vis dis aus no:

Accelerometer

Accelerometers yog cov cuab yeej paub zoo uas muaj txiaj ntsig zoo rau ntsuas lub zog zoo li qub thiab muaj zog. Lawv ntsuas qhov sib txawv ntawm kev nrawm nrawm hauv Accelerometer qhov kev siv lub koob npe thiab lub ntiaj teb gravitational field vector. ntawm no hauv qhov kev sim no peb siv Suab ua qhov tso tawm los ntawm Accelerometer. Suab yog lub kaum sab xis tus nqi uas yuav muab kev taw qhia ntawm cov phaj khoov nrog kev hwm rau y-axis ntawm Accelerometer. Cov duab hauv qab no tuaj yeem siv los ua qhov siv los nkag siab txog cov nqi suab.

PRINCIPAL

Bend_It tshuab tom qab ua haujlwm cov khoom siv nrog lub cav tsav, tom qab ntsuas cov khoom siv teb nrog Load cell thiab Accelerometer. Lub xovtooj ntawm tes ntsuas lub zog ib sab uas cov khoom tiv nrog. Accelerometer yog txhais tau tias ntsuas ntsuas qhov sib txawv hauv cov khoom. Cov ntaub ntawv khaws tseg raug xa raws li cov ntaub ntawv xa mus rau Excel daim ntawv uas nws txhua tus tuaj yeem sib piv ntawm cov phiaj xwm tawg. Qhov no tso cai rau tus tsim qauv saib ntau npaum li cas quab yuam nws siv rau cov khoom siv kom mus txog qhov yas deformation. Kev thauj khoom ib sab tau txo qis thaum cov khoom siv tau mus txog qhov pib ntawm kev ua haujlwm, thiab peb tuaj yeem pom tias cov khoom tsis rov qab, hauv qhov ua kom zoo, rau nws qhov qub. Txoj kev ntsuas no yog txoj hauv kev nrawm thiab yooj yim ntawm kev txheeb xyuas cov ntaub ntawv kev cai uas tej zaum me me dhau los yuav tsum tau sim siv cov nplai tshuab zom zaws.
