记北京创客展
8月11日我有幸跟徐总一起去观看了北京的一场创客展览，收益颇丰，接下来我将用图文及视频的方式向大家介绍一下我们在这次创客展中所看到的一些有趣的有学习意义的东西，以及我自己的一些感想与建议 1 集成巡线小车（KittenBot） kittenbot.cc 优点： 巡线速度特别快 且巡线精准 可红外或wifi或蓝牙控制 有预留接口 带有RGB彩灯，不同模式颜色不同，通过彩灯颜色展示小车的状态，效果炫酷 缺点： 对于一些情况，比较高的集成度并不适合初学者进行开发学习，传感器选择类型有限，自由搭配受到限制，一定程度上限制了开发者的思维，有局限性 2 发电模块 在这次展会中我们看到了这个小巧便捷的发电模块，通过手摇发电来控制一些小电流的低功率电子产品，节能环保，比较适合用来制作一些小项目，小玩具。在下边的视频中我们可以看到，一个发电模块连接一个dc motor，转动摇臂，通过正转跟反转可以控制电机向前转或者向后转。 通过外接一个dc稳压模块，我们也可以将这个发电模块与我们套件的一些器件配合使用。 3 音乐机器人 …Read the Rest
