Arduino是一个开放源码的电子原型平台，它可以让你用简单的硬件和软件来创建各种互动的项目。Arduino的核心是一个微控制器板，它可以通过一系列的引脚来连接各种传感器、执行器、显示器等外部设备。Arduino的编程是基于C/C++语言的，你可以使用Arduino IDE（集成开发环境）来编写、编译和上传代码到Arduino板上。Arduino还有一个丰富的库和社区，你可以利用它们来扩展Arduino的功能和学习Arduino的知识。
Arduino的特点是：
1、开放源码：Arduino的硬件和软件都是开放源码的，你可以自由地修改、复制和分享它们。
2、易用：Arduino的硬件和软件都是为初学者和非专业人士设计的，你可以轻松地上手和使用它们。
3、便宜：Arduino的硬件和软件都是非常经济的，你可以用很低的成本来实现你的想法。
4、多样：Arduino有多种型号和版本，你可以根据你的需要和喜好来选择合适的Arduino板。
5、创新：Arduino可以让你用电子的方式来表达你的创意和想象，你可以用Arduino来制作各种有趣和有用的项目，如机器人、智能家居、艺术装置等。
这是一个绘画/沙画制作机器人。它有两个伺服电机，由 Arduino Uno 原型板控制。它可以绘制不同的形状。

## 你的项目是关于什么的？
这个项目是关于一个可以在兰戈里上绘画和书写的机器人。它有两个伺服电机，由安装在 Arduino Uno 原型板上的 Atmega328p 微控制器控制。
你为什么决定做这个？
制作这个机器人的目的是为了在兰戈里上画任何形状。兰戈里是手绘的。我不擅长画兰戈里。所以我决定做一个机器人，可以帮我画兰戈里。
它是如何工作的？
它有两个伺服电机，由安装在 Arduino Uno 原型板上的 Atmega328p 微控制器控制。它的工作原理是逆运动学。待绘制图像的轮廓坐标存储在 Arduino 代码的一个数组中。
CAD设计
这是机器人的CAD设计图。我们可以看到，两个电机、两个连杆和一支铅笔。第一个电机放置在地面上。连杆与其轴连接。第二个电机安装在该轴上。另一个连杆连接到第二个电机的轴上。连杆末端连接着一支铅笔。铅笔的尖端指向目标点。当两个电机旋转时，借助地面上的铅笔，可以画出任何东西。这是真正的机器人，有 2 个马达、2 个连杆和一支笔作为追踪的末端执行器。
真实设计
图像到坐标的转换
要从图像中获取坐标，我们可以从这个网站获取帮助。这里我们只需要上传图像。我们需要它的坐标。图像将显示在下方。单击图形的边缘。将生成相应的坐标。所有坐标将显示在下方。复制它们，然后将它们存储在 Arduino 代码的数组中。
转换问题
但是伺服电机需要输入角度，并旋转到给定的角度。因此，我们必须将笛卡尔坐标转换为球坐标。这需要借助三角函数。
这是要到达的点。两条连线的长度相同。因此，计算该点到原点的距离D，以及高度H。我们可以轻松计算出所有角度。
绘制兰戈里的原因
我们不用笔在纸上画画。因为装置不够坚固，无法在纸上施加足够的压力。
不过，我们还是成功画了一些画。虽然画得不太好，但我们对结果很满意。
