控制机械臂

1 滑块控制

打开命令行并运行:

# mycobot 320-M5 版本的默认串行端口名称为"/dev/ttyUSB0",波特率为 115200。某些型号的串行端口名称为 "dev/ttyACM0"。如果默认串行端口名称有误,可以将串行端口名称更改为"/dev/ttyACM0"。
ros2 launch mycobot_320 slider_control.launch.py

它会打开 rviz2 和一个滑块组件,你会看到类似下面的内容:

然后,您可以在 rviz2 中通过拖动滑块来控制模型的移动。真实的 mycobot 机器人也会随之移动。

请注意:由于在命令输入的同时机械臂会移动到模型目前的位置,在您使用命令之前请确保 rviz 中的模型没有出现穿模现象 不要在连接机械臂后做出快速拖动滑块的行为,防止机械臂损坏

2 模型跟随

除了上面的控制,我们也可以让模型跟随真实的机械臂运动

打开一个命令行运行:

# mycobot 320-M5 版本的默认串行端口名称为"/dev/ttyUSB0",波特率为 115200。某些型号的串行端口名称为 "dev/ttyACM0"。如果默认串行端口名称有误,可以将串行端口名称更改为"/dev/ttyACM0"。
ros2 launch mycobot_320 mycobot_follow.launch.py

它将打开 rviz 以显示模型跟随效果

3 GUI 控制

在前者的基础上,本软件包还提供了一个简单的图形用户界面控制接口。这种方法意味着真正的机械臂是相互连接的,请连接到 mycobot。

打开命令行:

# mycobot 320-M5 版本的默认串行端口名称为"/dev/ttyUSB0",波特率为 115200。某些型号的串行端口名称为 "dev/ttyACM0"。如果默认串行端口名称有误,可以将串行端口名称更改为"/dev/ttyACM0"。
ros2 launch mycobot_320 simple_gui.launch.py

4 键盘控制

在 "mycobot_320pi "软件包中添加了键盘控制功能,并在 rviz 中实时同步。 该功能依赖于 pythonApi,因此请确保与真正的机械臂连接。

打开命令行并运行:

# mycobot 320-M5 版本的默认串行端口名称为"/dev/ttyUSB0",波特率为 115200。某些型号的串行端口名称为 "dev/ttyACM0"。如果默认串行端口名称有误,可以将串行端口名称更改为"/dev/ttyACM0"。
ros2 launch mycobot_320 teleop_keyboard.launch.py

操作效果如下:

命令行中将会输出 mycobot 信息,如下:

接下来,打开另一个 命令行:

ros2 run mycobot_320 teleop_keyboard

您将在命令行中看到以下输出:

Mycobot Teleop Keyboard Controller
---------------------------
Movimg options(control coordinations [x,y,z,rx,ry,rz]):
              w(x+)

    a(y-)     s(x-)     d(y+)

    z(z-) x(z+)

u(rx+)   i(ry+)   o(rz+)
j(rx-)   k(ry-)   l(rz-)

Gripper control:
    g - open
    h - close

Other:
    1 - Go to init pose
    2 - Go to home pose
    3 - Resave home pose
    q - Quit

在该终端中,您可以通过命令行中的按键控制机械臂的状态并移动机械臂。
