Kuma imyenda izunguruka, izwi kandi nk'imyenda izunguruka cyangwa yumisha, byahindutse ibikoresho byo murugo kuri banyiri amazu benshi kwisi. Yahinduye uburyo twumisha imyenda kandi ikura cyane mumyaka. Muri iki kiganiro, turasesengura iterambere nihindagurika ryimyenda yimyenda yumye nuburyo yabaye igice cyingenzi mubuzima bwacu bwa buri munsi.
Igitekerezo cyarotary airerguhera mu ntangiriro ya 1800, mugihe byari bimenyerewe kumanika imyenda kumurongo cyangwa kumurongo kugirango byume. Nyamara, ni inzira ikora isaba guhora yitabwaho, cyane cyane mubihe bibi. Ibi byatumye abahimbyi bategura uburyo bunoze kandi bunoze bwo kumisha imyenda. Rero, impuzu yimyenda yumye yavutse.
Imyenda ya mbere yimyenda yimyenda yari inkingi yoroshye yimbaho ifite imigozi myinshi yo kumanika imyenda. Abakoresha barashobora kuzunguruka intoki, berekana imyenda kumurasire yizuba n umuyaga kugirango bafashe mugukama. Imyenda ya rotary yumye yashushanyije yatezimbere mugihe cyo kwinjiza ibyuma hamwe nuburyo bukomeye bwo kuzunguruka.
Mu kinyejana cya 20 rwagati, icyuma cyizunguruka cyumye cyahindutse cyane. Isosiyete yatangiye gukora icyuma cyumisha hamwe nikintu gishobora kugwa, byoroshye kubika mugihe bidakoreshejwe. Ubu buryo bushya butuma ba nyiri urugo bakoresha umwanya wabo wo hanze neza. Byongeye kandi, ibyo byuma byumye birashobora guhinduka uburebure, bigatuma abakoresha bamanika kumesa murwego rwo hejuru rwakazi, bikagabanya imbaraga zumugongo.
Mugihe ikoranabuhanga ritera imbere, ibyuma byuma byuma bikomeza kugenda bihinduka. Ababikora batangiye kugerageza nibikoresho bitandukanye kugirango barusheho kuramba no guhangana nikirere. Ibyuma bitagira umwanda, aluminium, na plastike ni amahitamo akunzwe, bigatuma imyenda izunguruka irwanya ingese no kwangirika. Ibikoresho kandi bituma ibyuma byumye byoroha, bigafasha abayikoresha kubizenguruka byoroshye.
Iyindi terambere ryingenzi muguhindagurika kwimyenda yizunguruka ni kwinjiza ibikoresho nibindi bintu byiyongera. Isosiyete yatangiye gutanga imyenda izunguruka kugirango irinde imyenda imvura, ivumbi nimirasire yangiza ya UV. Moderi zimwe zifite ibikoresho bizunguruka bizunguruka cyangwa ibyuma bya beto kugirango byongere umutekano kandi birinde imyenda idahungabana mumuyaga mwinshi.
Mu myaka yashize, impungenge z’ibidukikije zatumye iterambere ryangiza ibidukikije byangiza ibidukikije. Ababikora benshi ubu bakora imyenda yimyenda ikozwe mubikoresho birambye kandi biteza imbere uburyo bwo kuzigama ingufu. Moderi zimwe zagenewe gukoresha imbaraga zizuba, hifashishijwe imirasire yizuba yubatswe kugirango ifashe mugukama. Izi nzira zangiza ibidukikije ntizigama ingufu gusa, ahubwo zigabanya na karuboni ikirenge kijyanye nuburyo gakondo bwo kumisha imyenda.
Nkibisabwarotary airerbyakomeje kwiyongera, igishushanyo gishya cyabayeho. Kurugero, imyenda ya 'Rotodry' ikubiyemo uburyo bwa swivel buzenguruka imyenda yose ukoze kuri buto. Uku kuzunguruka kwemeza ko impande zose zimyenda zihuye nizuba n'umuyaga, bikaviramo gukama vuba kandi neza.
Mu gusoza, imyenda yumuzunguruko yumye yagize iterambere ryinshi nihindagurika mugihe runaka. Kuva itangira ryoroheje nkigiti cyicishije bugufi cyibiti kugeza kuri moderi igezweho, byahinduye uburyo bwo kumisha imyenda. Hamwe nibintu bimeze nkuburebure bushobora guhinduka, amakadiri ashobora gusenyuka, hamwe n’ibidukikije byangiza ibidukikije, imyenda izunguruka yahindutse ibikoresho byingenzi mu ngo ku isi. Mugihe ikoranabuhanga rikomeje gutera imbere, turashobora kwitega ndetse nibindi bishya kandi bikora neza mugihe kizaza.
