| add-device | Guide for adding new devices to Uni-Lab-OS (接入新设备). Uses @device decorator + AST auto-scanning instead of manual YAML. Walks through device category, communication protocol, driver creation with decorators, and graph file setup. Use when the user wants to add/integrate a new device, create a device driver, write a device class, or mentions 接入设备/添加设备/设备驱动/物模型. |
添加新设备到 Uni-Lab-OS
第一步: 使用 Read 工具读取 docs/ai_guides/add_device.md,获取完整的设备接入指南。
该指南包含设备类别(物模型)列表、通信协议模板、常见错误检查清单等。搜索 unilabos/devices/ 获取已有设备的实现参考。
装饰器参考
@device — 设备类装饰器
from unilabos.registry.decorators import device
# 单设备
@device(
id="my_device.vendor", # 注册表唯一标识(必填)
category=["temperature"], # 分类标签列表(必填)
description="设备描述", # 设备描述
display_name="显示名称", # UI 显示名称(默认用 id)
icon="DeviceIcon.webp", # 图标文件名
version="1.0.0", # 版本号
device_type="python", # "python" 或 "ros2"
handles=[...], # 端口列表(InputHandle / OutputHandle)
model={...}, # 3D 模型配置
hardware_interface=HardwareInterface(...), # 硬件通信接口
)
# 多设备(同一个类注册多个设备 ID,各自有不同的 handles 等配置)
@device(
ids=["pump.vendor.model_A", "pump.vendor.model_B"],
id_meta={
"pump.vendor.model_A": {"handles": [...], "description": "型号 A"},
"pump.vendor.model_B": {"handles": [...], "description": "型号 B"},
},
category=["pump_and_valve"],
)
@action — 动作方法装饰器
from unilabos.registry.decorators import action
@action # 无参:注册为 UniLabJsonCommand 动作
@action() # 同上
@action(description="执行操作") # 带描述
@action(
action_type=HeatChill, # 指定 ROS Action 消息类型
goal={"temperature": "temp"}, # Goal 字段映射
feedback={}, # Feedback 字段映射
result={}, # Result 字段映射
handles=[...], # 动作级别端口
goal_default={"temp": 25.0}, # Goal 默认值
placeholder_keys={...}, # 参数占位符
always_free=True, # 不受排队限制
auto_prefix=True, # 强制使用 auto- 前缀
parent=True, # 从父类 MRO 获取参数签名
)
自动识别规则:
- 带
@action的公开方法 → 注册为动作(方法名即动作名) - 不带
@action的公开方法 → 自动注册为auto-{方法名}动作 _开头的方法 → 不扫描@not_action标记的方法 → 排除
@topic_config — 状态属性配置
from unilabos.registry.decorators import topic_config
@property
@topic_config(
period=5.0, # 发布周期(秒),默认 5.0
print_publish=False, # 是否打印发布日志
qos=10, # QoS 深度,默认 10
name="custom_name", # 自定义发布名称(默认用属性名)
)
def temperature(self) -> float:
return self.data.get("temperature", 0.0)
辅助装饰器
from unilabos.registry.decorators import not_action, always_free
@not_action # 标记为非动作(post_init、辅助方法等)
@always_free # 标记为不受排队限制(查询类操作)
设备模板
import logging
from typing import Any, Dict, Optional
from unilabos.ros.nodes.base_device_node import BaseROS2DeviceNode
from unilabos.registry.decorators import device, action, topic_config, not_action
@device(id="my_device", category=["my_category"], description="设备描述")
class MyDevice:
_ros_node: BaseROS2DeviceNode
def __init__(self, device_id: Optional[str] = None, config: Optional[Dict[str, Any]] = None, **kwargs):
self.device_id = device_id or "my_device"
self.config = config or {}
self.logger = logging.getLogger(f"MyDevice.{self.device_id}")
self.data: Dict[str, Any] = {"status": "Idle"}
@not_action
def post_init(self, ros_node: BaseROS2DeviceNode) -> None:
self._ros_node = ros_node
@action
async def initialize(self) -> bool:
self.data["status"] = "Ready"
return True
@action
async def cleanup(self) -> bool:
self.data["status"] = "Offline"
return True
@action(description="执行操作")
def my_action(self, param: float = 0.0, name: str = "") -> Dict[str, Any]:
"""带 @action 装饰器 → 注册为 'my_action' 动作"""
return {"success": True}
def get_info(self) -> Dict[str, Any]:
"""无 @action → 自动注册为 'auto-get_info' 动作"""
return {"device_id": self.device_id}
@property
@topic_config()
def status(self) -> str:
return self.data.get("status", "Idle")
@property
@topic_config(period=2.0)
def temperature(self) -> float:
return self.data.get("temperature", 0.0)
要点
_ros_node: BaseROS2DeviceNode类型标注放在类体顶部__init__签名固定为(self, device_id=None, config=None, **kwargs)post_init用@not_action标记,参数类型标注为BaseROS2DeviceNode- 运行时状态存储在
self.data字典中 - 设备文件放在
unilabos/devices/<category>/目录下
