12自由度六足机器人实现蓝牙遥控功能
本帖最后由 机器谱 于 2023-3-28 10:07 编辑1. 功能描述
R111样机是一款拥有12个自由度的串联仿生六足机器人。本文为这个六足机器人增加蓝牙遥控功能，可以通过安卓手机APP对机器人的动作实现遥控。

在这个示例中，我们采用了以下硬件，请大家参考：
主控板
Basra主控板（兼容Arduino Uno）
扩展板SH-SR舵机扩展板
舵机标准舵机
电池7.4V锂电池
通信
蓝牙串口模块
电路连接说明：
12自由度六足机器人结构上装有12个舵机，所以将采用 SH-SR舵机扩展板 。
舵机接线顺序：1、3； 4、 5； 6、 8；11、13；15、 21；24、26。

蓝牙串口模块可以通过杜邦线与扩展板进行连接，具体可以参考 如何使用探索者通信模块 一文中蓝牙串口模块部分。

3. 功能实现
下面的例程可以实现通过安卓手机APP按钮实现机器人前进、后退、左转、右转、跳舞等动作。安卓APP的设置也可以参考 如何使用探索者通信模块一文中蓝牙串口模块部分。
你也可以设计自己想要的动作，利用Controller 1.0b软件获取想要的动作参数，拷贝到下面的例程里。
将参考例程（R111_bluetooth.ino）下载到主控板：
