3piRobot是美國知名機(jī)器人研發(fā)公司Pololu所設(shè)計(jì)開發(fā)。 2009年11月份，億學(xué)通將其引入中國。在近半年試用中，充分領(lǐng)略了美國同行在智能車機(jī)器人設(shè)計(jì)方面所體現(xiàn)出來的創(chuàng)新、嚴(yán)謹(jǐn)?shù)木?，讓公司研發(fā)工程師受益匪淺。為了讓更多的機(jī)器人愛好者、學(xué)習(xí)者、開發(fā)者能感受這款源自美國 原汁原味 的產(chǎn)品，POLOLU授權(quán)億學(xué)通在中國試銷售3pi智能車。 需要說明的是，由于該產(chǎn)品屬于新開發(fā)產(chǎn)品，研發(fā)成本、運(yùn)輸費(fèi)用，使得前期這款3pi價(jià)格較國內(nèi)產(chǎn)品高很多，相信隨著中國市場的開展，價(jià)格會(huì)落到一個(gè)合理的價(jià)位上。1．描述Description: ...the3pihasbeenmorethoroughlyfieldtestedthananyotherrobotwe veworkedwith.We vehadwaytoomuchfunwiththislittlerobotandbythetimeyoufinishreadingthereview,you llprobablywanttobuyoneortwoforyourself.
