当我们启动NXP杯创新挑战赛时，我们期待高质量的项目。尽管如此，NXP杯自动驾驶汽车的水准还是让我们大吃一惊。从美学到功能，为NXP杯创新挑战赛设计的自动驾驶汽车令人印象深刻。这使得挑选三位获胜者变得非常困难。在我们的心目中，所有参与者都是赢家。
 
非常感谢恩智浦为世界各地的参赛者提供支持。但废话不多说，以下是本次创新挑战赛的获胜者!
 
第一名- VAXNA团队:以一个超酷的定制PCB，一个优秀的焊接工作，和优秀的文档，VAXNA团队完全震惊了我们。最高领导，瓦克斯纳团队!
 
第二名——rascar2020团队:以“rascar2020团队”的名字排名第二。我们很喜欢他们使用的3D打印部件，以及增加的部件，比如超声波传感器，以及增加下压力以达到更好转弯速度的风扇。拉斯卡2020团队的工作一团糟!
 
第三名- witek117队:最后但并非最不重要的是他们的骑士自动驾驶车witek117队。首先，我们很欣赏他们的车名:骑士:凯蒂，这个名字来自大卫·哈塞尔霍夫主演的经典电视剧《霹雳游侠》。“我们对他们使用定制的PIXY固件表示赞赏，这是一个了不起的壮举，而且汽车前部的激光获得了额外的分数。”
