Na faʻalauiloa e le sui o le NASA ia faʻamatalaga o le Ingenuity

I nai aso ua tuanaʻi sui o le NASA avanoa ofisa, i se faʻatalanoaga ma Spectrum IEEE, faʻaalia faʻamatalaga e uiga i le Ingenuity tutoʻatasi vaʻaia helikopa, lea na taunuʻu manuia i Mars o se vaega o le Mars 2020 misiona.

O se faʻapitoa vaega o le poloketi o le faʻaaogaina o le Qualcomm Snapdragon 801 SoC faʻavae faʻatonutonu laupapa, lea e faʻaaogaina i le gaosiga o telefoni poto. Ingenuity polokalama e faʻavae i luga o le Linux kernel ma tatala punaoa polokalame lele.

E tatau ona maitauina o le muamua faʻaaogaina lea o Linux i luga o le vateatea na lafoina i Martma. I se faʻaopopoga, o le faʻaaogaina o le open source software ma faʻapisinisi avanoa mea faigaluega e faʻatagaina ai tagata fiafia e faʻaputuputu a latou drones na o latou.

O lenei faʻaiuga e mafua mai i le mea moni o le puleaina o se lele drone manaʻomia sili sili computing mana nai lo le puleaina o se Rover, lea o loʻo faʻaauupegaina ma faia faapitoa chips ma faʻaopoopo puipuiga radiation. Mo se faʻataʻitaʻiga, o le tausisi pea i le lele e manaʻomia le faʻagaioia o le pulelaa faʻatonutonu i le fua faatatau o le 500 taʻamilosaga i le sekone, faʻapea foi ma le faʻataʻitaʻiga o ata i le fua faatatau o 30 faʻavaʻa i le sekone.

O le Snapdragon 801 SoC (Quad Core 2,26GHz, 2GB RAM, 32GB Flash) e faʻaaogaina e saunia ai se faʻavae Linux-faʻavae siosiomaga siʻosiʻomaga, lea e nafa ma gaioiga maualuga tulaga pei o vaʻaiga vaʻaiga faʻavae luga o mea puʻeata ata auiliili, faʻatonuga faʻatonuga, faʻatonuga faʻatonutonuina, telemetry gaosia ma le tausiga o uaealesi fesoʻotaʻiga ala.

Faagasologa fesoʻotaʻi ala UART Ofisa i lua microcontrollers (MCU Texas Instruments TMS570LC43x, ARM Cortex-R5F, 300 MHz, 512 KB RAM, 4 MB Flash, UART, SPI, GPIO) o loʻo faʻatinoina le vaʻalele.

O le lua microcontrollers o loʻo faʻaaogaina mo redundancy i le tulaga o le toilalo ma maua faʻamatalaga tutusa mai sensors. E naʻo le tasi le microcontroller o loʻo ola, ma le lona lua e faʻaaogaina o se faaleoleo ma i le tulaga o le le mafai e mafai ona ave faʻatonutonu. FPGA MicroSemi ProASIC3L e nafa ma le fesiitaʻiina o faʻamaumauga mai mea sulu i microcontrollers ma faʻafesoʻotaʻi ma gaioiga o loʻo faʻatonutonu lau, lea e fesuiaʻi foʻi i le sui o le microcontroller peʻa toʻilalo.

O le 'au, o le drone faʻaaogaina le SparkFun Electronics laser altimeter, o se tatalaina punaoa masini kamupani ma se tasi o foafoa o le faʻauiga o matala punaoa masini (OSHW). Faʻatasi ai ma isi vaega masani, o le gyrostabilizer (IMU) ma ata puʻeata o loʻo faʻaaogaina i telefoni poto e tu matilatila.

O le VGA mea puʻeata e faʻaaoga e siaki ai le nofoaga, faʻatonuga ma le saoasaoa e ala i faʻatusatusaga faʻavaʻa. O le lona lua 13 megapixel lanu mea puʻeata e faʻaaoga e fausia ai ata o le eria.

Aumai le atamai i Mars i le tasi fasi ma aveina i luga ma lauʻeleʻele e tasi lava o se mautinoa manumalo mo NASA, JPL's Tim Canham taʻu mai ia i matou.

Na fesoasoani Canham i le fausiaina o le polokalame faakomepiuta e faʻatautaia ai le Ingenuity. I le avea ai ma Ingenuity's Operations Leader, ua taulaʻi nei o ia i le fuafuaina o vaalele ma le faamaopoopoga ma le Perseverance rover team. Na matou talanoa ia Canham ia malamalama lelei pe faʻafefea ona faʻalagolago le Ingenuity i le tutoʻatasi mo ana malaga o loʻo sosoʻo mai i Mars.

O vaega o le polokalame e faʻatonutonu ai le lele, na atiaʻe i le NPL's JPL (Jet Propulsion Laboratory) mo laʻititi ma laʻititi ole laʻititi ole satelite faʻalelalolagi (cubsats) ma na atiaʻe mo le tele o tausaga o se vaega ole matala F Prime (F), tufatufaina i lalo ole Apache 2.0 laisene.

F Palemia faʻaavanoaina mea faigaluega mo le vave atinaʻeina o vaʻalele faʻatonutonu faiga ma fesoʻotaʻiga faʻapipiʻi talosaga. Ua vaevaeina polokalame vaalele i vaega taʻitasi ma le lelei faʻamatalaina polokalame interfaces.

I se faʻaopopoga i vaega faʻapitoa, o le C ++ faʻavae ua saunia ma le faʻatinoina o foliga e pei o le savali queuing ma tele-filo, faʻapea foi ma meafaigaluega faʻataʻitaʻiga e faʻatagaina ai oe e fesoʻotaʻi vaega ma otometi gaosia code.

Mulimuli pe afai e te fiafia e iloa atili e uiga i ai, oe mafai ona feutagai o le fesoʻotaʻiga lenei 


O mataupu o le tusitusiga e tausisi ia tatou mataupu silisili o amio lelei faʻatonu. E lipotia se mea sese kiliki iinei.

Ia avea muamua ma faamatalaga

Tuʻu lau faamatalaga

o le a le lomia lou tuatusi imeli.
