Nabani na ohamba equbha nenja uyazi ukuba kungcono ukuthabatha amanyathelo ambalwa emva nje kokuba umhlobo wakho onemilenze emine ephuma emanzini. Kuba inja emanzi kufuneka izivuthulule yome kuqala. Abaphandi baseGeorgia Institute of Technology baye bafumanisa ukuba kubaluleke kangakanani ukungcangcazela kwizilwanyana kunye nokuba kungakanani na ukungcangcazela kwahluka ukusuka kwisilwanyana ukuya kwesinye.
Abaphandi bafunda ukunyakaza okungcangcazelayo kweentlobo zezilwanyana ze-17. Ukusuka kwiimpuku ukuya kwizinja ukuya kwi-grizzlies, balinganisa ubude kunye nobunzima bezilwanyana ezingama-33 zizonke. Ngekhamera enesantya esiphezulu, barekhoda iintshukumo ezingcangcazelayo zezilwanyana.
Bafumanisa ukuba izilwanyana kufuneka zizivuthulule ngokufuthi ngakumbi xa zikhaphukhaphu.
Xa izinja zingcangcazela zomile, zibuyela emva naphambili malunga nezihlandlo ezisibhozo ngomzuzwana. Izilwanyana ezincinci, ezifana neempuku, zingcangcazela ngokukhawuleza. Kwelinye icala, ibhere eliyigrizzly lishukuma kane kuphela ngomzuzwana. Zonke ezi zilwanyana zifikelela kwi-70 yeepesenti zomile kwimizuzwana nje embalwa emva kokujikeleza kwazo.
Ukungcangcazela konga amandla
Kwizigidi zeminyaka, izilwanyana ziye zayiphucula indlela yazo yokungcangcazela. Uboya obumanzi bukhusela kakubi, ukuphuphuma kwamanzi avalelweyo kukhupha amandla kwaye umzimba uphole ngokukhawuleza. “Ngoko ngumbandela wobomi nokufa ukuhlala womile kangangoko kunokwenzeka kwimozulu epholileyo,” utsho uDavid Hu, intloko yeqela lophando.
Uboya buyakwazi ukufunxa amanzi amaninzi, nto leyo eyenza umzimba ube nzima. Ngokomzekelo, impuku emanzi kufuneka ithwale isihlanu sepesenti esongezelelweyo sobunzima bomzimba wayo ijikeleze nayo. Yiyo loo nto izilwanyana zizivuthulula zomile ukuze zingachithi amandla azo zithwele ubunzima obuninzi.
I-Slingshot isikhumba esikhululekile
Ngokwahlukileyo kubantu, izilwanyana ezinoboya zihlala zinezikhumba ezininzi ezivulekileyo, eziqhekezayo kunye nokunyakaza okunamandla kunye nokukhawulezisa ukunyakaza kuboya. Ngenxa yoko, izilwanyana nazo zoma ngokukhawuleza. Ukuba izicubu zesikhumba beziqinile njengabantu, beziya kuhlala zimanzi, abaphandi bathi.
Ngoko ukuba inja ngokukhawuleza izivuthulula ngamandla emva kokuhlamba kwaye itshiza amanzi kuyo yonke into kunye nabo bonke abantu abakummandla osondeleyo, oku akusiyo umbuzo wobukrwada, kodwa kuyimfuneko yokuziphendukela kwemvelo.
