3piRobot是美国知名机器人研发公司Pololu所设计开发。 2009年11月份，亿学通将其引入中国。在近半年试用中，充分领略了美国同行在智能车机器人设计方面所体现出来的创新、严谨的精神，让公司研发工程师受益匪浅。为了让更多的机器人爱好者、学习者、开发者能感受这款源自美国 原汁原味 的产品，POLOLU授权亿学通在中国试销售3pi智能车。 需要说明的是，由于该产品属于新开发产品，研发成本、运输费用，使得前期这款3pi价格较国内产品高很多，相信随着中国市场的开展，价格会落到一个合理的价位上。1．描述Description: ...the3pihasbeenmorethoroughlyfieldtestedthananyotherrobotwe veworkedwith.We vehadwaytoomuchfunwiththislittlerobotandbythetimeyoufinishreadingthereview,you llprobablywanttobuyoneortwoforyourself.
