QuickStart

Installation

1. Ensure Python 3.10 is installed

2. Install dependencies:

pip install robotarm-mcp-p340

Configuration for Cursor

There are three methods to configure MCP in Cursor:

Method 1: Python Module Configuration (Recommended for Installed Package)

If you've installed the package via pip:

{
  "mcpServers": {
    "mycobot": {
      "command": "Fill in the python path under the virtual environment folder where robotarm-mcp-p340 is installed",
      "args": ["-u", "-m", "mycobot_mcp"],
      "env": {
        "SIMULATE": "1"
      }
    }
  }
}

Example:

{
  "mcpServers": {
    "mycobot": {
      "command": "D:\\anaconda3\\envs\\test-robotarm\\python.exe",
      "args": ["-u", "-m", "mycobot_mcp"],
      "env": {
        "SIMULATE": "1"
      }
    }
  }
}

Method 2: Development Configuration (For GitHub Clone)

If you've cloned from GitHub and are developing:

{
  "mcpServers": {
    "mycobot": {
      "command": "Fill in the python path under the project's virtual environment folder",
      "args": [
        "-u",
        "-m",
        "mycobot_mcp"
      ],
      "env": {
        "SIMULATE": "1",
        "PYTHONPATH": "Fill in the absolute path to the src folder"
      },
      "cwd": "Fill in the absolute path to the project root"
    }
  }
}

Example:

{
  "mcpServers": {
    "mycobot": {
      "command": "D:\\Anaconda3\\envs\\mycobot-mcp\\python.exe",
      "args": [
        "-u",
        "-m",
        "mycobot_mcp"
      ],
      "env": {
        "SIMULATE": "1",
        "PYTHONPATH": "D:\\AI\\mycobot-mcp\\src"
      },
      "cwd": "D:\\AI\\mycobot-mcp"
    }
  }
}

Important Notes:

• "SIMULATE": "1" is for simulation testing without hardware. For real device testing, set SIMULATE to "0"

• Method 2 requires installing the project dependencies from requirements.txt in the project's virtual environment

• Must use -u flag to disable Python output buffering

• Set PYTHONPATH to include the src directory

• Adjust paths according to your installation

Method 3: Batch File Configuration (Windows)

1. Create a batch file start_mcp_server.bat:

@echo off
cd /d D:\AI\mycobot-mcp
set PYTHONPATH=D:\AI\mycobot-mcp\src
set SIMULATE=1
D:\Anaconda3\envs\mycobot-mcp\python.exe -u -m mycobot_mcp

2. Configure Cursor:

{
  "mcpServers": {
    "mycobot": {
      "command": "D:\\AI\\mycobot-mcp\\start_mcp_server.bat"
    }
  }
}

Configuration Steps

1. Open Cursor Settings (Ctrl+,)

2. Search for "MCP" or "Model Context Protocol"

3. Add the configuration using one of the methods above

4. Restart Cursor to apply changes

Verification

After successful configuration, you should see:

• ✅ "9 tools enabled" in the MCP status

• ✅ Tools available in chat: connect_robot, get_robot_status, etc.

Usage Examples

1. Connect to robot:

   • "Connect to my ultraArm P340 robot"

   • "Initialize robot on COM3 port" (adjust the number based on your device's actual COM port, default is 3)

2. Basic movements:

   • "Move the robot arm to position [200, 0, 150]"

   • "Set joint angles to [45, 30, -20]"

   • "Return to home position"

3. Gripper control:

   • "Open the gripper"

   • "Close gripper to pick up object"

   • "Turn on suction pump"

4. Complex tasks:

   • "Play with my cat using the robot arm"

   • "Draw a circle on the table"

   • "Show me how to write Chinese characters"

   • "Make the robot dance to music"

   • "Create a custom waving gesture sequence"

Development Mode

Set SIMULATE=1 to test without hardware:

export SIMULATE=1  # Linux/Mac
set SIMULATE=1     # Windows

Troubleshooting

If tools don't load properly:

1. Check MCP logs in Cursor:

   • View → Output → Select "MCP" channel

   • Look for error messages

2. Test the server locally:

   # For installed package
   python -m mycobot_mcp
   
   # For development (from project root)
   cd D:\AI\mycobot-mcp
   set PYTHONPATH=src
   python -m mycobot_mcp

3. Common issues and solutions:

   • "No module named 'mycobot_mcp'":

     • For development: Ensure PYTHONPATH includes the src folder

     • For installed: Run pip install -e . from project root

   • "Tools not loading":

     • Check that you're using -m mycobot_mcp not -m mycobot_mcp.server

     • Verify the cwd is set to project root in development mode

   • Configuration tips:

     • ✅ Always use -u flag for unbuffered output

     • ✅ Set PYTHONPATH to src folder (not src/mycobot_mcp)

     • ✅ Use cwd to set working directory for development

     • ❌ Don't run server.py directly

Safety Guidelines

⚠️ Important Safety Information:

1. Always ensure a clear workspace around the robot

2. Keep hands and objects away from moving parts

3. Use emergency stop if unexpected behavior occurs

4. Start with slow speeds when testing new movements

5. Never use massage demonstrations on humans

6. Supervise pet interactions at all times

快速开始

安装配置

1. 确保已安装 Python 3.10

2. 安装依赖：

pip install robotarm-mcp-p340

Cursor 配置方法

有三种方法在 Cursor 中配置 MCP：

方法 1：Python 模块配置（推荐用于已安装的包）

如果您已通过 pip 安装了包：

{
  "mcpServers": {
    "mycobot": {
      "command": "填写安装了robotarm-mcp-p340的虚拟环境文件夹下的python路径",
      "args": ["-u", "-m", "mycobot_mcp"],
      "env": {
        "SIMULATE": "1"
      }
    }
  }
}

示例如下：

{
  "mcpServers": {
    "mycobot": {
      "command": "D:\\anaconda3\\envs\\test-robotarm\\python.exe",
      "args": ["-u", "-m", "mycobot_mcp"],
      "env": {
        "SIMULATE": "1"
      }
    }
  }
}

方法 2：开发配置（用于从 GitHub 克隆的项目）

如果您从 GitHub 克隆并正在开发：

{
  "mcpServers": {
    "mycobot": {
      "command": "填写安装了该项目虚拟环境文件夹下的python路径",
      "args": [
        "-u",
        "-m",
        "mycobot_mcp"
      ],
      "env": {
        "SIMULATE": "1",
        "PYTHONPATH": "填写 src 文件夹的绝对路径"
      },
      "cwd": "填写项目根目录的绝对路径"
    }
  }
}

示例如下：

{
  "mcpServers": {
    "mycobot": {
      "command": "D:\\Anaconda3\\envs\\mycobot-mcp\\python.exe",
      "args": [
        "-u",
        "-m",
        "mycobot_mcp"
      ],
      "env": {
        "SIMULATE": "1",
        "PYTHONPATH": "D:\\AI\\mycobot-mcp\\src"
      },
      "cwd": "D:\\AI\\mycobot-mcp"
    }
  }
}

重要说明：

• "SIMULATE": "1"为无硬件设备的模拟测试，实机测试需要把SIMULATE值设置为"0"

• 方法二需要在项目虚拟环境中安装requirements.txt中的项目依赖

• 必须使用 -u 参数禁用 Python 输出缓冲

• 设置 PYTHONPATH 包含 src 目录

• 根据您的安装路径调整路径

方法 3：批处理文件配置（Windows）

1. 创建批处理文件 start_mcp_server.bat：

@echo off
cd /d D:\AI\mycobot-mcp
set PYTHONPATH=D:\AI\mycobot-mcp\src
set SIMULATE=1
D:\Anaconda3\envs\mycobot-mcp\python.exe -u -m mycobot_mcp

2. 配置 Cursor：

{
  "mcpServers": {
    "mycobot": {
      "command": "D:\\AI\\mycobot-mcp\\start_mcp_server.bat"
    }
  }
}

配置步骤

1. 打开 Cursor 设置（Ctrl+,）

2. 搜索 "MCP" 或 "Model Context Protocol"

3. 使用上述方法之一添加配置

4. 重启 Cursor 使配置生效

验证配置

配置成功后，您应该看到：

• ✅ MCP 状态显示 "9 tools enabled"

• ✅ 聊天中可用工具：connect_robot、get_robot_status 等

使用示例

1. 连接机器人：

   • "连接我的 ultraArm P340 机械臂"

   • "初始化 COM3 端口的机器人"（根据您设备的实际 COM 端口调整数字，默认是 3）

2. 基础运动：

   • "移动机械臂到位置 [200, 0, 150]"

   • "设置关节角度为 [45, 30, -20]"

   • "回到零位"

3. 夹爪控制：

   • "打开夹爪"

   • "闭合夹爪抓取物体"

   • "开启吸泵"

4. 复杂任务：

   • "用机械臂逗猫"

   • "在桌上画个圆"

   • "演示如何写汉字"

   • "让机器人跟着音乐跳舞"

   • "创建一个自定义的挥手动作序列"

开发模式

设置 SIMULATE=1 无需硬件测试：

export SIMULATE=1  # Linux/Mac
set SIMULATE=1     # Windows

故障排除

如果工具加载失败：

1. 检查 Cursor 的 MCP 日志：

   • 视图 → 输出 → 选择 "MCP" 通道

   • 查看错误信息

2. 本地测试服务器：

   # 对于已安装的包
   python -m mycobot_mcp
   
   # 对于开发模式（从项目根目录）
   cd D:\AI\mycobot-mcp
   set PYTHONPATH=src
   python -m mycobot_mcp

3. 常见问题和解决方案：

   • "No module named 'mycobot_mcp'"：

     • 开发模式：确保 PYTHONPATH 包含 src 文件夹

     • 已安装：从项目根目录运行 pip install -e .

   • "工具未加载"：

     • 检查是否使用 -m mycobot_mcp 而不是 -m mycobot_mcp.server

     • 验证开发模式下 cwd 设置为项目根目录

   • 配置提示：

     • ✅ 始终使用 -u 标志实现无缓冲输出

     • ✅ 设置 PYTHONPATH 为 src 文件夹（而不是 src/mycobot_mcp）

     • ✅ 使用 cwd 为开发设置工作目录

     • ❌ 不要再直接运行 server.py

安全指南

⚠️ 重要安全信息：

1. 确保机器人周围有足够空间

2. 运动时远离机械部件

3. 出现异常立即使用紧急停止

4. 测试新动作时使用低速

5. 按摩演示仅用于展示，勿用于真人

6. 与宠物互动时全程监督
