Umshini wokuxazulula cube kaRubik
Namuhla kunezinhlobo eziningi zemishini, izinhlobo eziningi ezidalwe ngazo hardware libre kanye nehardware yokuphathelene, kodwa kungokokuqala ngqa ukubona umshini odalelwe ukuxazulula cube a rubik sika. Umshini esikhuluma ngawo ubulokhu ukhona kudalwe futhi kwaguqulwa nguMaxim Tsoy, umsebenzisi odale umshini futhi uwubuyekeze kwaze kwaba yilapho esebenzisa izingxenye ezimbalwa ze Hardware Libre njengamabhodi e-Arduino kanye ne-Raspberry Pi model A.
Lo mshini usebenza kahle kakhulu, ushintsha izinjini ze-servo for stepper motors ezenza umshini ushintshe ubuso bekhubhu le-rubik ngokushelela. Okuhle kunakho konke ukuthi lo mshini ukhishwe ngokuphelele, okusho ukuthi, wonke amapulani kanye nesoftware ne-hardware esetshenzisiwe kunemininingwane futhi kuyashicilelwa ku ibhulogi yombhali.
Ngesikhathi sokuvuselelwa kokugcina, uTsoy ushintshe ubuchopho bomshini, ukusuka ebhodini le-Arduino kuye imodyuli yeCompute, Ibhodi le-Raspberry Pi elinamandla amancane nezesekeli kune-Raspberry Pi yokuqala futhi kwezinye izimo ilusizo njengalo mklamo ofanayo.
Umshini wokuxazulula ikhekhe le-rubik usebenzisa imodyuli ye-Raspberry Pi Compute
Ukusuka e-Arduino kuya ku-Raspberry Pi kube nzima kepha kwaphela ngokuphelele, yize u-Arduino engeke anyamalale kulo mshini ukuxazulula ikhekhe le-rubik. Enye yezinto ezibalulekile zalo mshini isithwebuli eskena indawo kobuso ngabunye ukucubungula bese wenza ukunyakaza. Lesi sithwebuli senziwe ngokuphelele ngebhodi le-Arduino elicubungula imininingwane ukuyithumela ku-Raspberry Pi futhi elisebenzisa i-algorithm yokwenza.
Mhlawumbe abaningi benu bazothi kungani nisebenzisa umshini oxazulula ikyubhu eyinkimbinkimbi kangaka ye-rubik ngenkathi thina ngokwethu singayixazulula ngesikhathi esincane kunalokho okusibiza ukudala umshini, uqinisile, kepha lo mshini ubuye uphelele ekufundeni ukusebenza yemishini, funda ukuthi ungaxhumana kanjani ne-Arduino ne-Raspberry Pi noma umane usebenzise ama-stepper motors. Ungakhohlwa ukuthi ukusebenza kwayo kungahle kufane nokwamanye amaphrinta e-3D lapho baskena khona into bese bephrinta amakhophi abo.
