物联网自动猫粮机 简单

头像 DFSH_Felix 2018.10.11 1885 7

项目背景

       当你忙于工作，中午无法回家；当你回家途中惨遭堵车，无法按时到家；当时需要出差，当你需要约会…...这些情况都会导致家里的宠物处于挨饿或无法按时按量吃饭的状态！ 宠物比人类脆弱的多，以上的种种情况都有可能导致宠物患上肠胃疾病！这时候，你就需要一款可以自动或者远程控制的智能猫/狗粮机，来帮你按时按量的投喂家里的小可爱们!并且可以统计小可爱们的吃饭时间，以便在需要的时候向宠物医生反馈，时刻关注家中宠物的健康！ 

        那么先看看我们需要准备些什么吧！~

材料清单

  • 3mm椴木板 X1
  • 4mm椴木板 X2
  • Gravity: UART OBLOQ - IoT物联网模块 X3 链接
  • Romeo V2 多合一Arduino兼容控制器 X4 链接
  • Gravity I2C OLED-2864 显示屏 X5 链接
  • 带编码器金属直流减速电机 (6V 300rpm 3.6Kg.cm) X6 链接
  • 数字触摸开关Touch(Arduino兼容) X7 链接
  • 75*2.3mmPVC水管 X8

步骤1 猫粮机结构件制作

木板激光切割

       首先，我们需要进行猫粮机整体结构的加工，考虑到拼装的便捷性和材料的成本，我们的猫粮机采用木板和螺丝固定的结构。猫粮机的激光切割图纸，我会放在帖子最后的资料中供大家下载，大家也可以在现有的基础上，给猫粮机增加更好看的外观，给家里的“主子”们做一个独一无二的猫粮机。

PVC水管切割

       木板切割完成后，我们需要制作猫粮机输送猫粮的管道，这个就需要我们之前准备的PVC水管（直径和厚度千万不要买错哦~）。我们需要切割一段178mm长的PVC水管，然后在其中一侧用手锯切出一个35mm长，5mm深的槽，以便于安装我们猫粮机的入口。

3D打印

       最后，我们还缺一个推动猫粮的绞龙，以及安装在PVC水管两侧防止猫粮从管道中掉落的封盖。3D打印时需要用到的STL文件，我也会在帖子最后的资料中贴上的~绞龙最终打印出来就是下图的效果啦~

步骤2 猫粮机的拼装

        完成了所有的结构件制作，接下来我们就要进到最繁琐的拼装环节！在进行拼装之前，提醒一下各位！在猫粮机外壳拼装的时候，需要在螺丝和螺母的基础上，添加一个垫片，增加结构的稳定性，也防止了用力过猛拧断木板的情况（即使这样也不要用力太猛！）！正确的安装方式如下~

      因为制作拼装图纸过于繁琐，我给大家一个安装到一半的图，以便大家理解拼装过程。拼装过程中，如果遇到一些不稳定的结构，各位可以使用热熔胶或者502辅助固定。

       拼装到还剩最后一块侧面板时，我们将主控以及各种模块放入机器中。

步骤3 烧录程序

        这一版的猫粮机，具有可以使用OBLOQ控制猫粮机运行模式的功能。向optic2发送数据1，猫粮机持续出粮；发送数据0，猫粮机停止出粮；发送数据2，猫粮机进入自动模式，外接的触摸传感器每隔一段时间（这段时间可以在程序中自行更改）允许猫咪触摸后出粮。烧录完程序后，将最后一块木板装上，猫粮机就制作完成啦！

总结

这一版的猫粮机还是有很多缺陷的，比如没有留更换电池的接口，结构还不够紧凑等。接下来会不断的改进这款猫粮机的，为大家的猫主子提供更好的投喂机器！
