| description | Guide for adding new resources (materials, bottles, carriers, decks, warehouses) to Uni-Lab-OS (添加新物料/资源). Uses @resource decorator for AST auto-scanning. Covers Bottle, Carrier, Deck, WareHouse definitions. Use when the user wants to add resources, define materials, create a deck layout, add bottles/carriers/plates, or mentions 物料/资源/resource/bottle/carrier/deck/plate/warehouse. |
添加新物料资源
Uni-Lab-OS 的资源体系基于 PyLabRobot,通过扩展实现 Bottle、Carrier、WareHouse、Deck 等实验室物料管理。使用 @resource 装饰器注册,AST 自动扫描生成注册表条目。
资源类型
| 类型 | 基类 | 用途 | 示例 |
|---|
| Bottle | Well (PyLabRobot) | 单个容器(瓶、小瓶、烧杯、反应器) | 试剂瓶、粉末瓶 |
| BottleCarrier | ItemizedCarrier | 多槽位载架(放多个 Bottle) | 6 位试剂架、枪头盒 |
| WareHouse | ItemizedCarrier | 堆栈/仓库(放多个 Carrier) | 4x4 堆栈 |
| Deck | Deck (PyLabRobot) | 工作站台面(放多个 WareHouse) | 反应站 Deck |
层级关系: Deck → WareHouse → BottleCarrier → Bottle
WareHouse 本质上和 Site 是同一概念 — 都是定义一组固定的放置位(slot),只不过 WareHouse 多嵌套了一层 Deck。两者都需要开发者根据实际物理尺寸自行计算各 slot 的偏移坐标。
@resource 装饰器
from unilabos.registry.decorators import resource
@resource(
id="my_resource_id",
category=["bottles"],
description="资源描述",
icon="",
version="1.0.0",
handles=[...],
model={...},
class_type="pylabrobot",
)
创建规范
命名规则
name 参数作为前缀:所有工厂函数必须接受 name: str 参数,创建子物料时以 name 作为前缀,确保实例名在运行时全局唯一
- Bottle 命名约定:试剂瓶-Bottle,烧杯-Beaker,烧瓶-Flask,小瓶-Vial
- 函数名 =
@resource(id=...):工厂函数名与注册表 id 保持一致
子物料命名示例
for k, v in sites.items():
v.name = f"{name}_{v.name}"
carrier[0] = My_Reagent_Bottle(f"{name}_flask_1")
carrier[i] = My_Solid_Vial(f"{name}_vial_{ordering[i]}")
sites=create_homogeneous_resources(
klass=ResourceHolder,
locations=[...],
name_prefix=name,
)
self.warehouses = {
"堆栈1左": my_warehouse_4x4("堆栈1左"),
"试剂堆栈": my_reagent_stack("试剂堆栈"),
}
其他规范
- max_volume 单位为 μL:500mL = 500000
- 尺寸单位为 mm:
diameter, height, size_x/y/z, dx/dy/dz
- BottleCarrier 必须设置
num_items_x/y/z:用于前端渲染布局
- Deck 的
__init__ 必须接受 setup=False:图文件中 config.setup=true 触发 setup()
- 按项目分组文件:同一工作站的资源放在
unilabos/resources/<project>/ 下
__init__ 必须接受 serialize() 输出的所有字段:serialize() 输出会作为 config 回传到 __init__,因此必须通过显式参数或 **kwargs 接受,否则反序列化会报错
- 持久化运行时状态用
serialize_state():通过 _unilabos_state 字典存储可变信息(如物料内容、液体量),只存 JSON 可序列化的基本类型
资源模板
Bottle
from unilabos.registry.decorators import resource
from unilabos.resources.itemized_carrier import Bottle
@resource(id="My_Reagent_Bottle", category=["bottles"], description="我的试剂瓶")
def My_Reagent_Bottle(
name: str,
diameter: float = 70.0,
height: float = 120.0,
max_volume: float = 500000.0,
barcode: str = None,
) -> Bottle:
return Bottle(
name=name,
diameter=diameter,
height=height,
max_volume=max_volume,
barcode=barcode,
model="My_Reagent_Bottle",
)
Bottle 参数:
name: 实例名称(运行时唯一,由上层 Carrier 以前缀方式传入)
diameter: 瓶体直径 (mm)
height: 瓶体高度 (mm)
max_volume: 最大容积(μL,500mL = 500000)
barcode: 条形码(可选)
BottleCarrier
from pylabrobot.resources import ResourceHolder
from pylabrobot.resources.carrier import create_ordered_items_2d
from unilabos.resources.itemized_carrier import BottleCarrier
from unilabos.registry.decorators import resource
@resource(id="My_6SlotCarrier", category=["bottle_carriers"], description="六槽位载架")
def My_6SlotCarrier(name: str) -> BottleCarrier:
sites = create_ordered_items_2d(
klass=ResourceHolder,
num_items_x=3, num_items_y=2,
dx=10.0, dy=10.0, dz=5.0,
item_dx=42.0, item_dy=35.0,
size_x=20.0, size_y=20.0, size_z=50.0,
)
for k, v in sites.items():
v.name = f"{name}_{v.name}"
carrier = BottleCarrier(
name=name, size_x=146.0, size_y=80.0, size_z=55.0,
sites=sites, model="My_6SlotCarrier",
)
carrier.num_items_x = 3
carrier.num_items_y = 2
carrier.num_items_z = 1
ordering = ["A1", "B1", "A2", "B2", "A3", "B3"]
for i in range(6):
carrier[i] = My_Reagent_Bottle(f"{name}_vial_{ordering[i]}")
return carrier
WareHouse / Deck 放置位
WareHouse 和 Site 本质上是同一概念:都是定义一组固定放置位(slot),根据物理尺寸自行批量计算偏移坐标。WareHouse 只是多嵌套了一层 Deck 而已。推荐开发者直接根据实物测量数据计算各 slot 偏移量。
WareHouse(使用 warehouse_factory)
from unilabos.resources.warehouse import warehouse_factory
from unilabos.registry.decorators import resource
@resource(id="my_warehouse_4x4", category=["warehouse"], description="4x4 堆栈仓库")
def my_warehouse_4x4(name: str) -> "WareHouse":
return warehouse_factory(
name=name,
num_items_x=4, num_items_y=4, num_items_z=1,
dx=10.0, dy=10.0, dz=10.0,
item_dx=147.0, item_dy=106.0, item_dz=130.0,
resource_size_x=127.0, resource_size_y=85.0, resource_size_z=100.0,
model="my_warehouse_4x4",
col_offset=0,
layout="row-major",
)
warehouse_factory 参数说明:
dx/dy/dz:第一个 slot 相对 WareHouse 原点的偏移(mm)
item_dx/item_dy/item_dz:相邻 slot 间距(mm),需根据实际物理间距测量
resource_size_x/y/z:每个 slot 的可放置区域尺寸
layout:影响 slot 标签和坐标映射
"row-major":A01,A02,...,B01,B02,...(行优先,适合横向排列)
"col-major":A01,B01,...,A02,B02,...(列优先)
"vertical-col-major":竖向排列,y 坐标反向
Deck 组装 WareHouse
Deck 通过 setup() 将多个 WareHouse 放置到指定坐标:
from pylabrobot.resources import Deck, Coordinate
from unilabos.registry.decorators import resource
@resource(id="MyStation_Deck", category=["deck"], description="我的工作站 Deck")
class MyStation_Deck(Deck):
def __init__(self, name="MyStation_Deck", size_x=2700.0, size_y=1080.0, size_z=1500.0,
category="deck", setup=False, **kwargs) -> None:
super().__init__(name=name, size_x=size_x, size_y=size_y, size_z=size_z)
if setup:
self.setup()
def setup(self) -> None:
self.warehouses = {
"堆栈1左": my_warehouse_4x4("堆栈1左"),
"堆栈1右": my_warehouse_4x4("堆栈1右"),
}
self.warehouse_locations = {
"堆栈1左": Coordinate(-200.0, 400.0, 0.0),
"堆栈1右": Coordinate(2350.0, 400.0, 0.0),
}
for wh_name, wh in self.warehouses.items():
self.assign_child_resource(wh, location=self.warehouse_locations[wh_name])
Site 模式(前端定向放置)
适用于有固定孔位/槽位的设备(如移液站 PRCXI 9300),Deck 通过 sites 列表定义前端展示的放置位,前端据此渲染可拖拽的孔位布局:
import collections
from typing import Any, Dict, List, Optional
from pylabrobot.resources import Deck, Resource, Coordinate
from unilabos.registry.decorators import resource
@resource(id="MyLabDeck", category=["deck"], description="带 Site 定向放置的 Deck")
class MyLabDeck(Deck):
_DEFAULT_SITE_POSITIONS = [
(0, 0, 0), (138, 0, 0), (276, 0, 0), (414, 0, 0),
(0, 96, 0), (138, 96, 0), (276, 96, 0), (414, 96, 0),
]
_DEFAULT_SITE_SIZE = {"width": 128.0, "height": 86.0, "depth": 0}
_DEFAULT_CONTENT_TYPE = ["plate", "tip_rack", "tube_rack", "adaptor"]
def __init__(self, name: str, size_x: float, size_y: float, size_z: float,
sites: Optional[List[Dict[str, Any]]] = None, **kwargs):
super().__init__(size_x, size_y, size_z, name)
if sites is not None:
self.sites = [dict(s) for s in sites]
else:
self.sites = []
for i, (x, y, z) in enumerate(self._DEFAULT_SITE_POSITIONS):
self.sites.append({
"label": f"T{i + 1}",
"visible": True,
"position": {"x": x, "y": y, "z": z},
"size": dict(self._DEFAULT_SITE_SIZE),
"content_type": list(self._DEFAULT_CONTENT_TYPE),
})
self._ordering = collections.OrderedDict(
(site["label"], None) for site in self.sites
)
def assign_child_resource(self, resource: Resource,
location: Optional[Coordinate] = None,
reassign: bool = True,
spot: Optional[int] = None):
idx = spot
if spot is None:
for i, site in enumerate(self.sites):
if site.get("label") == resource.name:
idx = i
break
if idx is None:
for i in range(len(self.sites)):
if self._get_site_resource(i) is None:
idx = i
break
if idx is None:
raise ValueError(f"No available site for '{resource.name}'")
loc = Coordinate(**self.sites[idx]["position"])
super().assign_child_resource(resource, location=loc, reassign=reassign)
def serialize(self) -> dict:
data = super().serialize()
sites_out = []
for i, site in enumerate(self.sites):
occupied = self._get_site_resource(i)
sites_out.append({
"label": site["label"],
"visible": site.get("visible", True),
"occupied_by": occupied.name if occupied else None,
"position": site["position"],
"size": site["size"],
"content_type": site["content_type"],
})
data["sites"] = sites_out
return data
Site 字段说明:
| 字段 | 类型 | 说明 |
|---|
label | str | 槽位标签(如 "T1"),前端显示名称,也用于匹配 resource.name |
visible | bool | 是否在前端可见 |
position | dict | 物理坐标 {x, y, z}(mm),需自行测量计算偏移 |
size | dict | 槽位尺寸 {width, height, depth}(mm) |
content_type | list | 允许放入的物料类型,如 ["plate", "tip_rack", "tube_rack", "adaptor"] |
参考实现: unilabos/devices/liquid_handling/prcxi/prcxi.py 中的 PRCXI9300Deck(4x4 共 16 个 site)。
