Ano, je to plaz. Zahrab\u00e1v\u00e1 se do p\u00edsku Sahary, jako by byla pod vodou.

Tento t\u00fdden univerzita ve W\u00fcrzburgu zve\u0159ejnila video robota. Vypad\u00e1 to jako st\u0159\u00edbrn\u00e1 mini ledni\u010dka. Za\u0159\u00edzen\u00ed je um\u00edst\u011bno na testovac\u00edm m\u00edst\u011b simuluj\u00edc\u00edm povrch Rud\u00e9 planety. Neroluje se. Zavrt\u00ed se. Ka\u017ed\u00e9 z jeho \u010dty\u0159 kol kresl\u00ed osmi\u010dku: naraz\u00ed do prachu, siln\u011b zatla\u010d\u00ed a vr\u00e1t\u00ed se po stejn\u00e9 dr\u00e1ze. <\/p>\n

“Kola napodobuj\u00ed charakteristickou interakci zv\u00ed\u0159ete [p\u00edse\u010dn\u00e9 je\u0161t\u011brky] se zem\u00ed.” <\/p>\n<\/blockquote>\n

Amenosis Lopez z Wurzburgu poznamenal, \u017ee robot zanech\u00e1v\u00e1 sinusov\u00e9 stopy. Vytv\u00e1\u0159\u00ed pod\u00e9ln\u00fd a bo\u010dn\u00ed tah. A prost\u011b se to h\u00fdbe. <\/p>\n

Pro\u010d tradi\u010dn\u00ed kola nefunguj\u00ed<\/h3>\n

V\u011bt\u0161ina z n\u00e1s je zvykl\u00e1 myslet na Mars rover jako na WALL-E<\/strong>. \u0160irok\u00e9 p\u00e1sy, kulat\u00e1 kola, solidn\u00ed in\u017een\u00fdrstv\u00ed. <\/p>\n

To je pro tuto oblast chyba. <\/p>\n

P\u00edsek je podvodn\u00edk. P\u0159ed vte\u0159inou byl pevn\u00fd, ale nyn\u00ed se chov\u00e1 jako kapalina. P\u0159idejte svahy, nerovn\u00e9 povrchy a n\u00e1hl\u00e1 kluzk\u00e1 m\u00edsta… a rover se zasekne. On se top\u00ed. \u010cek\u00e1. P\u0159\u00edroda to vy\u0159e\u0161ila p\u0159ed miliony let pomoc\u00ed p\u00edse\u010dn\u00e9 je\u0161t\u011brky. Navzdory n\u00e1zvu to nen\u00ed ryba. Toto je scolopendra (skink). <\/p>\n

Na povrchu to vypad\u00e1 norm\u00e1ln\u011b. Pohybuje se na mal\u00fdch tlapk\u00e1ch. <\/p>\n

V podzem\u00ed je to jin\u00fd tvor. Rentgen ukazuje, jak je\u0161t\u011brka krout\u00ed t\u011blem. Siln\u00fd tlak. P\u0159ekon\u00e1v\u00e1n\u00ed odporu. Doslova kmit\u00e1 zem\u00ed jako pstruh vodou. In\u017een\u00fd\u0159i z Georgia Institute of Technology to pozorovali a dali se do pr\u00e1ce. V roce 2011 vytvo\u0159ili svou robotickou verzi. Zjistili, \u017ee \u0161pi\u010dat\u00e1 hlava je\u0161t\u011brky nen\u00ed jen roztomil\u00e1. Vytv\u00e1\u0159\u00ed v\u00fdtah. To pom\u00e1h\u00e1 tvorovi snadn\u011bji \u201eplavat\u201c. <\/p>\n

Potopit se nebo plavat<\/h3>\n

Nov\u00fd rover z W\u00fcrzburgu p\u0159esahuje standardn\u00ed syst\u00e9my kol. Bezpodm\u00edne\u010dn\u011b. <\/p>\n

Tam, kde se kulat\u00e1 kola chv\u011bj\u00ed a klouzaj\u00ed, tato osciluj\u00edc\u00ed kola z\u016fst\u00e1vaj\u00ed v kurzu. Z\u016fst\u00e1vaj\u00ed stabiln\u00ed. Cesta k \u00fasp\u011bchu ale nebyla jednoduch\u00e1. Prvn\u00ed prototypy byly p\u0159\u00edli\u0161 t\u011b\u017ek\u00e9. Prost\u011b se topili. Bam. Zmizel. T\u00fdm se vr\u00e1til k v\u00fdkres\u016fm, roz\u0161\u00ed\u0159il kola a shodil v\u00e1hu. Leh\u010d\u00ed znamen\u00e1 vy\u0161\u0161\u00ed. <\/p>\n

P\u0159ijme NASA tuto technologii? <\/p>\n

Z\u00edtra asi ne. <\/p>\n

St\u00e1le pot\u0159ebujeme v\u011bt\u0161\u00ed kontrolu. Skute\u010dn\u00e9 prokluzov\u00e1n\u00ed v poln\u00edch podm\u00ednk\u00e1ch je chaotick\u00e9 a obt\u00ed\u017en\u00e9. A co n\u00e1klad? A co t\u011b\u017ek\u00e9 v\u011bdeck\u00e9 p\u0159\u00edstroje? Existuje mnoho prom\u011bnn\u00fdch. Ale design funguje. To je pocta evolu\u010dn\u00edmu g\u00e9niovi. Kone\u010dn\u011b v\u011bnujeme pozornost tomu, jak zv\u00ed\u0159ata p\u0159e\u017e\u00edvaj\u00ed v drsn\u00e9m prost\u0159ed\u00ed. <\/p>\n
