Mauto eU.S. akataura vhiki ino kuti akafambira mberi zvikuru mukuedza kwawo kukudziridza bara rinozvitungamirira. Muna February, "marobhoti akangwara" - zvombo zve.50-caliber zvakagadzirirwa nemichina inocherechedza - zvakapasa bvunzo dzazvo dzakabudirira zvikurusa dzokupfura chaiko kusvikira zvino, maererano neDefense Advanced Research Projects Agency, kana kuti DARPA.

Nemamwe mashoko, iye zvino haufaniri hako kuva mupfuri akanaka kuti urove chinangwa. Gadziriro yacho yakagadzirwa neDARPA's Extreme Accuracy Tasked Ordnance purogiramu, inozivikanwa seEXACTO. "Sezvinotaura basa reDARPA, EXACTO yakaratidza zvakanga zvambofungidzirwa kuti hazvibviri: kutungamirira nguva dzose kwepfuti ine kabhiridha kaduku kuti irove", akadaro Jerome Dunn, maneja wepurogiramu yeDARPA. "Ichi chiratidziro chomoto chaiwoiwo chakabva mugunza rakajairika chakaratidza kuti EXACTO inokwanisa kurova zvinangwa zvinofamba uye zvinodzivisa nokururama kwakanyanyisa pamatanho anokwanisa kuonekwa nevanopfura nepfuti dzenguva dzose. Kuisa mano okutungamirira kweEXACTO muukobvu huduku hwe50 caliber ndiko kubudirira kukuru uye kunovhura musuo kune zvingagona kuitika mune ramangwana mumapurisa anotungamirirwa pamakumbo ose", Dunn akadaro. Mavhidhiyo akagoverwa neDARPA anoratidza mabara acho achichinja-chinja zvakasimba ari mudenga sezvaanotevera vavariro dzawo. Zvose izvi zvinomutsa mifananidzo yomunhu wemifananidzo inoratidzwa pamakatuni ari kutiza zvine utsinye bara rinomutevera kwose kwaanoenda. Bhomba iri riri kufamba nemazana emakiromita paawa.

Zvinangwa zvepurogiramu yeEXACTO zviri kupa vapfuri zvakarurama pakureba kukuru, kurwisa nharidzano nokukurumidza uye kuwedzera chengeteko yamauto eAmerica, DARPA yakadaro.
.50-caliber mabara akashongedzerwa nema sensors eoptical anogona kutevera zvinangwa zvinofamba. "Mabara akangwara" anogona kubetsera vapfuri kutsiva mhepo dzakasimba. Chinangwa chepurogiramu yacho ndechokupa vapfuri nzvimbo yakakura uye kuita kuti mauto eAmerica ave akachengeteka zvikuru.
