+ | Muneshi Mitsuoka fra Kyushu Universitet har skrevet PhD om vibrationer i baeltekoeretoejer. Han har ogsaa lavet noget software der kan simulere et design af baeltemodulerne. Jeg har uploadet praesentationen jeg har faaet af han [[http:// | ||
+ | Her er link til deres artikler: | ||
+ | === Observations so far === | ||
+ | *Kraftoverfoersel fra drivhjul til baelte: Hvis drivhjulet placeres nede i bageste hjoerne af baeltet, vil drivhjulet traekke i baeltet der ligger paa jorden mens det er belastet af hele robottens vaegt. Det burde goere baeltemodulet mere effektivt ved fremadkoersel., | ||
+ | *Baelte med stort drivhjul - Se ogsaa Armadillo 3 arbejdsdokument.\\ Det giver min 3 taender i baeltet hele tiden | ||
+ | *De 3 skiver/hjul i hvert modul der baere vaegten bevaeger sig op og ned hver gang de koerer hen over en af metal delene i baeltet og hullerne i mellem dem. Jo hurtigere man koere jo mindre er problemet, men ikke desto mindre er det med til at lave vibretioner i rammen. | ||
+ | *Vi har snakket med Prof. Meier fra TU Berlin. Han mete at vibrationerne kunne opstaa af flere grunde. | ||
+ | *Polygon effekt; jo stoerre drivhjulet er jo bedre. Det skal have et ulige antal taender, og det skal vaere 17 eller derover for at mindske effekten. | ||
+ | *Hvis huset er monteret paa daempere kan det skabe vibrationerne, | ||
+ | *Vibrationerne kan stamme fra alle tandhjul, og det kan vaere meget svaert at fidne ud af praecis hvor de opstaar henne. | ||
+ | *Observationer efter feltforsoeg: | ||
