Kwadalwa ngo 11.13
Emhlabeni wezobuchwepheshe bokwenziwa, ukubona kubalulekile. Kweminyaka eminingi, amakhamera e-2D abeke imikhawulo kumarobhothi ekuboniseni okuphakeme—ashiya izikhala ekwahlukaniseni ibanga, ekuqondeni izinto, nasekuzivumelaneni ngesikhathi sangempela. Namuhla, amakhamera okukhanya okujulile avele njengoshintsho lomdlalo, ehlanganisa amarobhothi ngokuqonda.3D “amehlo”okuthile okukhumbuza ukuqonda kwesikhala komuntu. Le ndaba yocwaningo ihlola izicelo zangempela zobuchwepheshe bokuhlola ukujula ezimbonini, ibheka ukuthi kanjani ixazulula izinselelo ezindala ze-robotics futhi ivula amathuba amasha.
1. I-Why: Kungani Ukuqonda Ubukhulu Kubalulekile Kwezobuchwepheshe Be-Robotics
Ngaphambi kokungena ezicini zocwaningo, ake sikhanyise ngenani eliyisisekelo lamakhamera okuthola ubukhulu. Ngokwehlukile kumakhamera e-2D athatha kuphela umbala nokwakheka, amakhamera okuthola ubukhulu akala ibanga phakathi kwamakhamera nezinto ezikwenkambu. Lokhu kudala "imephu yobukhulu"—i-3D blueprint esetshenziswa ama-robot ukuze:
• Hamba ezindaweni ezixakile ngaphandle kokuhlangana
• Bamba izinto ezihlukahlukene ngezimo/nobukhulu ngokunembile
• Qaphela futhi uhlukanise izinto ezimweni zokukhanya okuphansi noma eziphakeme zokuphikisana
• Lungisa ukuhamba ukuze kuhambisane nezimo ezishintshashintshayo (isb., abantu abahambayo noma impahla eshintshashintshayo)
Izobuchwepheshe ezintathu eziphakeme zokuhlola ukujula zisebenza kumarobhothi anamuhla:
• Time-of-Flight (ToF): Ikhipha ama-pulse okukhanya futhi ibala ibanga ngokukala ukuthi ukukhanya kuthatha isikhathi esingakanani ukubuyela emuva (ifanele ama-robot ahamba ngokushesha).
• Uhlanga Olwakhiwe: Lukhombisa iphethini (isb., igebe) phezu kwezindawo; ukuguquguquka kwephethini kukhombisa ukujula (ukunemba okuphezulu emisebenzini eseduze).
• I-Stereo Vision: Isebenzisa amakhamera amabili ukuze ikopishe ukubona kwabantu ngezindlela ezimbili, iqhathanisa izithombe ukuze ibale ukujula (okungabiza kancane kuma-robot angaphandle).
Manje, ake sithathe isikhathi sokuqhathanisa ukuthi lezi zinkampani zixazulula kanjani izinkinga zangempela emikhakheni emine ebalulekile.
