Hloov Kho Yam Tsiaj Qus - Joystick Steering - Tshiab thiab Txhim Kho: 7 Cov Kauj Ruam (nrog Duab)

2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Hloov Kho 8/1/2019: Ob xyoos tom qab ua tiav txoj haujlwm no, Kuv tau tsim thiab tsim ntau lub rooj sib tham hauv Circuit kom yooj yim los hloov cov rooj zaum no. Thawj lub rooj tsav xwm hauv vaj huam sib luag yuav luag zoo ib yam li cov kev cai protoboard tau muag ntawm no, tab sis hloov pauv yog pawg kws tshaj lij tsim khoom uas siv Arduino Nano. Kuj tseem muaj qhov hloov pauv hloov rau thawj lub rooj tswj hwm cov khoom lag luam (nws muaj cov tsav tsheb hauv lub tshuab tsav tsheb), nrog rau pawg thawj coj uas txuas rau hauv pawg tswj hwm cov khoom lag luam thiab ua raws nws cov joysticks, yog li ua rau lawv siv tau yooj yim dua. Nov yog tag nrho cov ntaub ntawv rau cov laug cam: https://github.com/willemcvu/Bumblebee-dual-motor-… Yog tias koj xav tau ib qho ntawm cov laug cam no, thov hu rau kuv ntawm kuv qhov blog thiab peb tuaj yeem mus los ntawm qhov ntawd: https:/ /willemhillier.wordpress.com/contact-me/

Phau ntawv no tau sau los ntawm Willem Hillier, tus tub ntxhais kawm ntawm Champlain Valley Union High School, nyob hauv Hinesburg, VT. Txoj haujlwm no tau ua tiav sab hauv thiab sab nrauv ntawm Tsim Qauv thiab Engineering Robotics chav kawm qhia los ntawm Olaf Verdonk.

Thaum lub Peb Hlis Ntuj xyoo 2017, ib tus kws kho mob lub cev hauv ib cheeb tsam tau hu rau tsev kawm theem siab thiab nug yog tias peb puas tuaj yeem hloov kho Fisher Price Wild Thing rau ib tus joystick siv, los ntawm kev ua raws li Cov Lus Qhia no: https://www.instructables.com/id/ Tsiaj-Yam-Hloov Kho/

Peb tau coj cov lus qhia no, thiab txhim kho tus qauv tsim qhov uas peb tuaj yeem ua tau. Cov cheeb tsam uas peb txhim kho suav nrog:

• Electronics mounting/thaiv
• Code
• Joystick thiab joystick mount
• PVC mounting system
• Backrest, headrest thiab lwm yam kev txhawb nqa
• Caster log

Peb tsis tau siv lub sonar sensor thiab piezo beeper hauv peb tsim zoo li qub tau ua.

Hnub kawg tsim hnub, thaum peb teeb tsa qhov kev txhawb nqa zaum kawg thiab nthuav tawm txoj haujlwm rau tus ntxhais, cov xov xwm hauv zos tau tshwm sim. Lawv tau ua yeeb yaj kiab thiab xam phaj ntau tus neeg, thiab tom qab tshaj tawm hauv xov xwm hauv zos, cov vis dis aus tau nthuav tawm hauv xov xwm hauv tebchaws, nrog rau hauv ntau qhov chaw hauv online suav tsis txheeb.

Cov lus qhia no tsis suav nrog zoo ib yam li thawj qhov kev qhia yog, tab sis yog "ntxiv" uas hais txog tsuas yog thaj chaw uas peb tau hloov.

Thov txim rau cov duab hauv qab no thoob plaws Cov Lus Qhia no. Kuv muaj iPhone 5 thaum lub sijhawm ua haujlwm no thiab nws tsis muaj lub koob yees duab zoo tshaj …

DISCLAIMER: Champlain Valley Union High School lossis ib qho yog tias nws cov tub ntxhais kawm, kws qhia ntawv, thiab cov neeg ua haujlwm tsis muaj lub luag haujlwm rau kev raug mob rau ib tus neeg lossis ua rau puas rau yam khoom suav nrog lub tsheb los ntawm kev hloov kho. Txhua yam kev hloov kho kuj tseem yuav tsis muaj qhov lees paub los ntawm cov chaw tsim khoom ntawm lub tsheb

Kauj Ruam 2: Hluav Taws Xob Mounting/thaiv

Hloov pauv ntawm txhua qhov tsim nyog cov xov hlau ncaj qha mus rau Adafruit Trinket Pro, Kuv tau xaiv los tsim PCB uas muaj txhua qhov tsim nyog sib txuas tau tawg.

Kuv siv perfboard, thiab siv tus poj niam lub taub hau rau Trinket Pro. Kuv siv txiv neej lub taub hau rau lub zog, servo, thiab txuas nrog joystick. Lub nrawm potentiometer tau muab muag ncaj qha rau ntawm pawg tswj hwm no, tsis zoo li qhov tsim qauv qub uas qhov kev hloov kho lub zog potentiometer tau sab nraud rau pawg tswj hwm. Qhov no yog qhov ntseeg tau ntau dua (tsis yog tawm tsam tus txuas) thiab yooj yim dua los tsim.

Ib qho ntxiv, muaj ob txoj kev hloov pauv uas tswj lub joystick header ua haujlwm. Ib qho hloov pauv x-axis teeb liab ntawm ob lub taub hau, thiab lwm qhov hloov pauv lub teeb liab y-axis. Txhua lub taub hau yog xaim "rov qab" lwm qhov - piv txwv li av thiab VCC tau hloov pauv txoj haujlwm los ntawm lwm lub taub hau. Qhov no tso cai rau lub joystick hloov ntawm sab laug thiab sab tes ua haujlwm yooj yim los ntawm kev hloov lub joystick lub taub hau thiab tig ob lub keyboards, yam tsis rov sau dua ntawm tus tswj.

Kauj ruam 3: Code

Thaum sim thawj tus lej, kuv pom tias nws yog laggy heev. Tom qab qee qhov kev tshawb fawb/ntsuas, nws tau txiav txim siab tias lub sonar code ua rau lub voj tswj tau ua haujlwm qeeb heev thaum tsis muaj lub suab sonar txuas nrog. Qhov no yog vim tias Arduino yuav xa tawm "ping" mus rau lub suab sensor, thiab tos lub sijhawm kom tau txais "ping" rov qab los ntawm lub suab sensor. Thaum tsis muaj lub suab sonar txuas, nws yeej tsis tau txais ping rov qab, tab sis tos ib pliag kom tau txais ib qho ua ntej thaum kawg lub sijhawm.

Tom qab tshem cov cai ntawd ntxiv rau lwm cov cai tsis tsim nyog (tshwj xeeb cov cai tsim los khiav lub tsheb nrog lub kauj servo), nws tau ua haujlwm zoo heev.

Kauj Ruam 4: Joystick thiab Joystick Mount

Thawj tus qauv siv tus qauv 2-axis potentiometer joystick los ntawm kev tswj chaw taws teeb rau lub dav hlau, thiab lwm yam. ib tus ntiv tes xoo. Peb tau xaiv los siv 2-axis joystick nrog lub pob tuav kom yooj yim siv. Kuv tsim thiab 3D luam tawm lub mount rau tus joystick. Tag nrho, nws tau mus dhau 4 qhov kev hloov kho ua ntej tau txais kev txaus siab.

Muaj ntau yam uas yuav tsum nco ntsoov txog lub joystick mount:

• Nws siv ob lub qhov taub txhawm rau txhawm rau txhawm rau txhawm rau 1 "PVC. Txhawm rau txiav txim siab qhov loj me me xav tau rau qhov no, peb tau luam tawm txheej" ntsuas rings "nrog qhov sib txawv me ntsis sab hauv (saib daim duab saum toj no).
• Cov ntaub ntawv tshwj xeeb no xav tau kev txhawb nqa kom luam tau zoo tshaj plaws - Kuv tau luam tawm ntawm Ultimaker 3. Kuv xav tias nws yuav luam tawm ntawm ib sab, tab sis nws tej zaum yuav tsis tawm los zoo heev. Kuv tau txuas nrog tus qauv tsis-txhawb-xav tau ib yam.
• Muaj U-shaped channel txiav tawm ntawm sab hauv uas tso cai rau kab mus nruab nrab ntawm lub qhov tawm thiab lwm lub zog.
• Kuv tus qauv siv lub laser-txiav acrylic sab saum toj, uas tuaj yeem yooj yim 3D luam tawm

Kauj Ruam 5: PVC Mounting System

Zoo li qhov tsim qauv qub, peb siv PVC los tsim ib puag ncig lub tsheb. Cov thav duab no muab kev tiv thaiv ntau ntxiv rau cov neeg siv, nrog rau cov ntsiab lus yooj yim rau lwm qhov xws li joystick thiab taub hau.

Peb siv dhau-bolts txhawm rau txhim kho PVC thav duab rau lub thav duab uas twb muaj lawm ntawm plaub lub ntsiab lus (saib daim duab saum toj no; cov ntsiab lus teeb tsa tau nyob puag ncig liab).

Kauj Ruam 6: Backrest, Headrest thiab Lwm Cov Qauv Txhawb

Xav txog tias peb tab tom tsim lub rooj zaum muaj log, txhawb cov qauv thiab ua cov khoom lag luam ergonomic yog qhov tseem ceeb heev. Muaj peb thaj chaw uas tau txhim kho zoo dua qub los ntawm Qhov Tsiaj Qub.

1. Lub nraub qaum

Peb tau siv daim ntawv ua npuas dej, nrog ob daim duab peb sab zoo li ntoo sib dhos ntawm nws thiab lub rooj zaum qub, yog li lub nraub qaum yog lub kaum ntse ntse. Cov neeg tsav tsheb tau siv los tiv thaiv kev teeb tsa tag nrho.

2. Sab Txoj Cai Txhawb Nqa Cov Qauv

Peb siv daim ntawv hlau txuas rau sab nraub qaum txiv kab ntxwv uas qhwv ib ncig ntawm ob sab ntawm lub duav ntawm tus neeg siv. Ua npuas ncauj tau qhwv ncig "cov lus qhia" ntawm daim hlau no. Saib duab.

3. Lub taub hau

Lub nraub qaum nraub qaum yog qhov zoo ntawm kev txhawb nqa rov qab, tab sis nws tsis siab txaus los txhawb tus neeg siv lub taub hau hauv peb qhov xwm txheej. Vim li no, lub taub hau tau ntxiv. Peb tau nqa lub taub hau tawm ntawm tus neeg siv lub rooj zaum muaj log (phau ntawv), thiab yooj yim ntsia nws mus rau ntawm lub rooj ncaws pob.

Kauj Ruam 7: Caster Log

Lub log caster qub thiab nws cov qauv txhawb nqa yog yas, muaj txoj hauv kev ua si ntau dhau, thiab tsis yob zoo txhua. (saib daim duab saum toj no kom pom qhov sib cais). Peb tau xaiv los hloov lub log caster nrog lub log roj hmab tig log tsim los siv rau hauv qab ntawm cov tsheb laub, thiab lwm yam.

Kuv tsim ob daim hlau hauv Fusion 260 uas yuav haum rau sab saum toj thiab hauv qab ntawm cov yas yas tig lub nraub qaum tsheb (saib daim duab). Cov phaj no tau txiav tawm ntawm CNC ntshav txiav. Ib qho me me ntawm cov raj hlau tau txuas rau hauv txhua lub qhov ntawm cov phaj no. Cov ntsia hlau ntsia mus rau sab saum toj phaj, phaj hauv qab, thiab tom qab ntawd lub qhov nyob hauv cov phaj txuas ntawm lub log log.

Ua tsaug rau kev nyeem Cov Lus Qhia no, thiab pov npav rau nws hauv PVC Contest thiab Ua Kom Nws Sib Tw!
