Ngokusho kwemibiko yabezindaba bakwamanye amazwe, irobhothi laseDelta lingasetshenziswa kabanzi emgqeni wokuhlanganisa ngenxa yejubane lalo kanye nokuguquguquka kwalo, kodwa lolu hlobo lomsebenzi ludinga isikhala esiningi. Futhi muva nje, onjiniyela baseHarvard University bathuthukise inguqulo encane kunazo zonke emhlabeni yengalo yerobhothi, ebizwa ngokuthi iMilliDelta. Njengoba igama lisikisela, iMillium+Delta, noma i-Delta encane, ingamamilimitha ambalwa nje ubude futhi ivumela ukukhethwa okunembile, ukupakisha, kanye nokukhiqizwa, ngisho nakwezinye izinqubo ezingangenisi kakhulu.
Ngo-2011, ithimba lase-Harvard's Wyssyan Institute lasungula indlela yokukhiqiza eqondile yama-microrobots abawabiza ngokuthi ukukhiqizwa kwesistimu ye-pop-up microelectromechanical (MEMS). Eminyakeni embalwa edlule, abacwaningi basebenzise lo mbono, bakha irobhothi elizihlanganisayo elikhasa kanye nerobhothi lezinyosi elisheshayo elibizwa ngokuthi iRobobee. I-MilliDelct yakamuva nayo yakhiwe kusetshenziswa lobu buchwepheshe.
I-MilliDelta yenziwe ngesakhiwo esihlanganisiwe esinama-laminated kanye namajoyinti amaningi aguquguqukayo, futhi ngaphezu kokufeza ubuhlakani obufanayo nerobhothi le-Delta elinobukhulu obugcwele, ingasebenza endaweni encane njenge-cubic millimeters eziyi-7 enokunemba kwama-micrometers ayi-5. I-MilliDelta ngokwayo ingu-15 x 15 x 20 mm kuphela.
Ingalo encane yerobhothi ingalingisa ukusetshenziswa okuhlukahlukene kwezingane zayo ezinkulu, ithole ukusetshenziswa ekuqoqeni nasekupakisheni izinto ezincane, njengezingxenye ze-elekthronikhi elabhorethri, amabhethri noma ukusebenza njengesandla esizinzile sokuhlinzwa okuncane. I-MilliDelta isiqede ukuhlinzwa kwayo kokuqala, ihlanganyela ekuhlolweni kwedivayisi yokwelapha ukuthuthumela kokuqala komuntu.
Umbiko wocwaningo ohlobene ushicilelwe ku-Science Robotics.
