Vzhledem k posunu term\u00ednu sout\u011b\u017ee oproti lo\u0148sk\u00e9mu roku byla na\u0161e \u00fa\u010dast na leto\u0161n\u00edm Nap\u00e1jeni Sluncem v\u00edce ne\u017e hektick\u00e1.

Vzhledem k\u00a0tomu, \u017ee na konstrukci robot\u016f bylo \u201em\u00e1lo \u010dasu\u201c, vsadili jsme letos na kvantitu. Nem\u011bli jsme \u010das ov\u011b\u0159it, kter\u00e1 konstrukce bude p\u0159i leto\u0161n\u00edch zm\u011bn\u011bn\u00fdch pravidlech \u00fasp\u011b\u0161n\u011bj\u0161\u00ed a tak jsme sestrojili celkem 7 sout\u011b\u017en\u00edch robot\u016f.\u00a0 V\u00fdsledek byl pro n\u00e1s p\u0159ekvapen\u00edm. Na\u0161\u00edm favoritem byl robot Dark Walker II<\/a>. Tento robot navazoval na \u00fasp\u011b\u0161nou konstrukci procesorem \u0159\u00edzen\u00e9ho robota z\u00a0lo\u0148sk\u00e9ho roku. Nakonec dos\u00e1hl a\u017e t\u0159et\u00edho nejkrat\u0161\u00edho \u010dasu mezi na\u0161imi roboty. Tak moc to zase nevadilo, proto\u017ee se um\u00edstil na prvn\u00edm m\u00edst\u011b ve sv\u00e9 kategorii, proto\u017ee ostatn\u00ed roboti v\u00a0kategorii procesorem \u0159\u00edzen\u00fdch nedojely. Z\u0159ejm\u011b i ostatn\u00ed roboti v\u00a0t\u00e9to kategorii byly v\u00a0\u010dasov\u00e9 t\u00edsni a jejich tv\u016frci nesta\u010dili roboty v\u010das odladit.<\/p>\n

N\u00e1m Dark Walker za\u010dal jezdit a\u017e v\u00a002:30 r\u00e1no p\u0159ed sout\u011b\u017e\u00ed a p\u0159i sout\u011b\u017ei m\u011bl zjevn\u00e9 probl\u00e9my. V\u00a0prvn\u00ed j\u00edzd\u011b neodstartoval. To v\u0161ak bylo chybou start\u00e9ra, kter\u00fd z\u00a0n\u011bj odstranil pap\u00edr a pak ho vr\u00e1til zp\u011bt. Tato situace by z\u0159ejm\u011b \u0161la ve firmware robota o\u0161et\u0159it, ale nezbyl na to \u010das. V\u00a0lo\u0148sk\u00e9m roce se n\u00e1m stalo p\u0159esn\u011b to sam\u00e9 p\u0159i prvn\u00ed j\u00edzd\u011b, ale robot se s\u00a0t\u00edm vypo\u0159\u00e1dal. Ve druh\u00e9 j\u00edzd\u011b bylo zase jasn\u011b vid\u011bt, jak s sebou robot v\u00a0polovin\u011b dr\u00e1hy \u0161kubl a d\u00e1le nezrychloval. P\u0159\u00ed\u010dinu tohohle \u0161kubnut\u00ed zat\u00edm nezn\u00e1me.\u00a0<\/p>\n

Za prv\u00e9 bylo pou\u017eito polarizovan\u00e9 rel\u00e9 pouze s\u00a0jednou c\u00edvkou. Sou\u010dasn\u011b s\u00a0t\u00edm byla vy\u0159e\u0161ena komutace nap\u011bt\u00ed na t\u00e9to c\u00edvce pomoc\u00ed p\u0159\u00eddavn\u00e9ho klopn\u00e9ho obvodu z\u00a0dvou bipol\u00e1rn\u00edch tranzistor\u016f. Za druh\u00e9 bylo rel\u00e9 pro sp\u00edn\u00e1n\u00ed motoru nahrazeno\u00a0 N-FET tranzistorem, kter\u00fd jsme objevili v\u00a0Li-Ion bateri\u00edch pro mobiln\u00ed telefon.\u00a0 Proto\u017ee v\u00a0leto\u0161n\u00edm roce byl zkr\u00e1cen \u010das, kter\u00fd m\u016f\u017ee robot str\u00e1vit na startu na polovinu, bylo nutn\u00e9 lo\u0148sk\u00fd kondenz\u00e1tor 1F\/5,5V nahradit men\u0161\u00edm. Sehnali jsme 10mF\/10V. Tento kondenz\u00e1tor je zase p\u0159\u00edli\u0161 mal\u00fd a tak jsme ho museli nab\u00edt na vy\u0161\u0161\u00ed nap\u011bt\u00ed. To jsme vy\u0159e\u0161ili tak, \u017ee jsme zapojili v\u00edce mal\u00fdch sol\u00e1rn\u00edch \u010dl\u00e1nk\u016f do s\u00e9rie. Tyto \u010dl\u00e1nky jsme zakoupili na lo\u0148sk\u00e9m ro\u010dn\u00edku od z\u00e1stupce firmy Solartec.

Op\u011bt jsme nezjistili, jak kolegov\u00e9 ze \u0160umperka dok\u00e1zali ty \u010dl\u00e1nky na\u0159ezat, proto\u017ee to taj\u00ed.

Zapojen\u00ed pro komutaci nap\u011bt\u00ed na c\u00edvce rel\u00e9 jsme okoukali na jednom \u010d\u00ednsk\u00e9m v\u00fdrobku<\/a>, ve kter\u00e9m jsme objevili i skv\u011bl\u00e9 motorky a mal\u00e9 p\u0159evodovky. Tyto motorky a p\u0159evodovky jsme pou\u017eili u na\u0161ich dal\u0161\u00edch \u00fasp\u011b\u0161n\u00fdch konstrukc\u00ed. Kvalitu t\u011bchto mechanick\u00fdch prvk\u016f, mysl\u00edm, prok\u00e1zal robot Brutus<\/a>. Jednalo se o \u010dist\u011b elektromechanick\u00e9ho robota, kter\u00fd m\u011bl p\u0159\u00edmo p\u0159ipojen motor na s\u00e9rioparaleln\u00ed kombinaci 2×4 sol\u00e1rn\u00ed \u010dl\u00e1nky. U tohoto robota jsme nejv\u00edce experimentovali s\u00a0pr\u016fm\u011brem kol. Nakonec se poda\u0159ilo k\u00a0dan\u00e9 p\u0159evodovce sehnat kola, kter\u00e1 tohoto robota vynesla na t\u0159et\u00ed m\u00edsto! P\u0159ed\u010dil ho pouze n\u00e1\u0161 robot Marconi a z\u00e1hadn\u00fd robot \u010d. 51, kter\u00fd prvn\u00ed j\u00edzdu jel p\u0159es 9s a druhou zajel za skv\u011bl\u00fd \u010das 1,5s a u kter\u00e9ho nezn\u00e1me jeho princip. Z\u00a0uveden\u00e9ho je vid\u011bt, \u017ee se jen velmi t\u011b\u017eko konstruuje robot s\u00a0elektronikou, kter\u00fd by v\u00fdrazn\u011b konkuroval \u010dist\u011b mechanick\u00e9mu robotu s\u00a0vyv\u00e1\u017een\u00fdmi mechanick\u00fdmi prvky v\u016f\u010di zat\u011b\u017eovac\u00ed charakteristice sol\u00e1rn\u00edch \u010dl\u00e1nk\u016f. Podstatnou v\u00fdhodou pro takov\u00e9to roboty je letm\u00fd start, kter\u00fd jim umo\u017e\u0148uje b\u011bhem n\u011bkolika des\u00edtek centimetr\u016f p\u0159ekonat nep\u0159\u00edznivou oblast zat\u011b\u017eovac\u00ed charakteristiky.<\/p>\n
