Jet Propulsion Laboratory ea NASA (JPL) e na le phatlalatsoa hore ba ntse ba sebetsana le mohopolo o mocha oa roboto bakeng sa tlhahlobo ea asteroid e sa hlokeng maoto, mabili, lienjine tsa rokete, kapa mofuta ofe kapa ofe. Khopolo ena e bitsoa Hedgehog e kopantseng ka botlalo thepa ea "hardware".
Moralo oa Hedgehog
JPL e sebetsa morerong ona hammoho le Univesithi ea Stanford California le Institute of Technology ea Massachusetts mane Cambridge. Moralo o ikhethileng oa Hedgehog o e lumella ho sebetsana le liphephetso tsa ho lekola litopo tse nyane ka matla a khoheli a fokotsehileng. 'Mele ena e nyane sebakeng e kenyelletsa li-asteroid, li-comet le likhoeli tse nyane.
“Hedgehog ke roboto ea mofuta o fapaneng e neng e tlo tlolela holimo ebe e oa holimo ho fapana le ho theteha ka mabili. E bōpehile joaloka khubine 'me e khona ho sebetsa ho sa tsotellehe hore na e lula lehlakoreng lefe, ” Issa Nesnas, ho boletse moetapele oa sehlopha sa JPL.
Ha e le hantle, Hedgehog ke cube e nang le li-spikes tse robeli tse tsamaeang ka ho ohla le ho phunya mabili a mararo a kahare. Nakong ea motsamao, li-spikes li sireletsa roboto liphellong tse mpe tsa sebaka seo 'me li sebetsa joalo ka maoto nakong ea ho tlola le ho oela. "Li-spikes li ka boela tsa kenya lisebelisoa tse kang li-thermal probes ho nka mocheso oa bokaholimo ha roboto e oela," ho boletse Nesnas.
Ka boeona, boima ba mofuta ona bo ka ba lik'hilograma tse 11. Leha ho le joalo, bafuputsi ba lumela hore e ka ba boima bo feta ha e kentsoe lisebelisoa tse kang lik'hamera le li-spectrometer. Ka liletsa, boima ba eona bo ne bo ka fihla ho li-lbs tse 5.
How It Works
Hedgehog e ile ea etsa liteko tsa microgravity ho lifofane tse ts'oanang. Nakong ea liteko ka Phuptjane 2015 ka har'a sefofane sa NASA sa C-9 bakeng sa lipatlisiso tsa microgravity, mekhoa e 'meli ea Hedgehog e bonts'itse mefuta e' maloa ea motsamao.
Maneuvers e fumanoeng e kenyelletsa "yaws" kapa sesebelisoa se fetohileng, le "lifefo tse matla" tse hlahisang sesebelisoa holimo ho tloha ka lebaka la ho ohla ho mabifi. Tsamaiso ena e ne e ka ba molemo bakeng sa ho potoloha libakeng tse fapaneng tse kang lehlabathe, majoe le leqhoa le nang le khoheli e nyane.

"Re bonts'itse ka lekhetlo la pele litlhahlobo tsa rona tsa Hedgehog tse etsang taolo e laoloang le ho oela libakeng tse kang tsa comet," ho boletse. Robert Reid, moenjiniere ea etellang pele morerong oa JPL.
“Ka ho laola tsela eo u pshatlang maqhubu ka eona, u ka fetola lehlakore la Hedgehog le qhomang. Morero e ne e le ho leka lits'ebetso tse peli tsa li-braking le ho utloisisa melemo le mathata a tsona, ”ho boletse Marco Pavone, moetapele oa sehlopha sa Stanford, ea hlahisitseng mohopolo oa Hedgehog le Nesnas ka 2011.
Ho ea ka bafuputsi, kaho ea roboto ea Hedgehog e theko e tlase ho feta ea rover ea setso. Ntle le moo, tse 'maloa tsa lisebelisoa tsena li ka fofa hammoho ka bo-mme. Bokhachane bo ka sebelisa liroboto tse ngata hang kapa ka mekhahlelo.
Bafuputsi ba ntse ba sebetsa ka boikemelo ba Hedgehog. Sena se bolela hore ba batla ho eketsa hore na liroboto li ka etsa eng ntle le ho fumana litaelo ho tsoa Lefatšeng. Ho fihlela joale, ho bonahala ba ntse ba le Phase 2 ea nts'etsopele ea eona.
