中秋节刚过,大家月饼盒应该还有,不要扔,可以做点小玩意。
机器狗的创意来自B站石桥北的视频,他使用了一块ESP32芯片和打印件加四个舵机实现,应该说是比较复杂的,需要有3D打印机打印外壳,还得会手机编程,有一定的专业度。
我这个简略版核心部件一块ASR芯片+4个舵机,四个舵机就是四条腿,ASR芯片本身带离线对话功能,自己设计一下对话控制舵机就好了。如果要增加趣问性,可以加一块OLED屏幕显示一些操作指令和绘制一些表情,
如上图,asrpro芯片包含六个舵机引脚pwm0到pwm5,我们只使用了四个,剩下两个有兴趣的还可以加上个尾巴和头,或者加上红外,温湿度传感器之类,oled屏将会占去两个,其他引脚就看大家发挥了。
最好是方形的盒子,这样好定位,贴着盒子底部,在盒子两侧一边挖两个方形的洞,如上图,正好可以把舵露出来舵机头为好,口的大小以能卡住固定镙丝的地方为宜。可以先使用纸片沿着舵机屁股裁一块相同大小的纸片,然后用这个纸片在盒子上比划出大小,然后使用美工刀挖出来。易拉罐应该也可以的,不过要使用胶带包一下,防止划破手,如下:
最终如下,:
接线:
PA2,PA3,PA5,PA6初始化为四个舵机,
PA0和PA1初始化为OLED屏。
