2. Introduction to DevReady

What is DevReady?

DevReady (Development-Ready) is an asset standard that upgrades NVIDIA's SimReady. SimReady made 3D assets physically accurate (measured mass, friction, deformation). DevReady makes them cognitively and operationally complete, and edge-portable.

A DevReady asset carries, in one file:

Layer	What it holds	Projects to
BODY	Robot structure: graph kinematics (closed-loop), geometry, device-comm topology	USD
MIND	Task knowledge (markdown), agent skills (JSON)	OKF + A2A
JOURNAL	Lifetime telemetry, PHM health record (grows on-device)	MCAP + MAVLink

Why DevReady exists

Today, a robot is described by 5+ sidecar files that drift apart:

robot.urdf  +  scene.usd  +  docs/*.md  +  agent.json  +  log.mcap  +  config.yaml

No single tool understands all of them. None runs on the robot. They diverge over the robot's life. DevReady solves this: one .flux = the whole robot, through its entire lifecycle.

SimReady vs DevReady

	SimReady	DevReady
Carries	scene + physics	scene + knowledge + agent + lifetime journal
Agent-native	no (needs runtime)	yes (self-describing, flux inspect)
Composition	USD layers (scene-centric)	LIVRPS (decentralized, each robot = autonomous node)
Robot model	tree (URDF)	graph, closed loops first-class
Edge/MCU	no (desktop-only)	yes (lean C on Cortex-M7)
Lifecycle	born in sim, dies in sim	born in reality, perpetually real

The lifecycle

GENERATE → REUSE → OPERATE → (loop forever)

1. Generate: a .flux is born (design → body; add knowledge; add skills)
2. Reuse: project to USD (sim), OKF (VLA), A2A (orchestration) — all from one source
3. Operate: the same file accrues telemetry + PHM on-device (MCU)
4. The file is the digital thread. No sidecar drift.

Who benefits?

• Robotics teams: one artifact replaces the drifting folder
• Sim platforms (Newton, Isaac Lab, Gazebo): FLUXmeme is the single source behind USD/MCAP
• VLA / agent startups: agents read assets without a runtime
• Standards bodies: MIT, spec-first, open governance, foundation-bound

DevReady 入门(中文)

DevReady 是什么?

DevReady(开发就绪)是一种资产标准,是 NVIDIA SimReady 的升级版。SimReady 让 3D 资产 物理准确(实测质量、摩擦、形变)。DevReady 让它们认知与操作完整,且可上边缘。

一个 DevReady 资产在一个文件里承载:

层	承载	投影到
BODY	机器人结构:graph 运动学(闭链)、几何、设备拓扑	USD
MIND	任务知识(markdown)、agent 技能(JSON)	OKF + A2A
JOURNAL	终身遥测、PHM 健康档案(设备上生长)	MCAP + MAVLink

为什么需要 DevReady

今天,一个机器人被 5+ 个 sidecar 文件描述,它们会漂移分离:

robot.urdf  +  scene.usd  +  docs/*.md  +  agent.json  +  log.mcap  +  config.yaml

没有一个工具同时理解所有文件。没有一个能在机器人本体上运行。它们随机器人寿命漂移。 DevReady 解决这个问题:一个 .flux = 整个机器人,贯穿全生命周期。

生命周期

生成 → 复用 → 运维 → (循环)

1. 生成:.flux 诞生(设计→身体;加知识;加技能)
2. 复用:投影到 USD(仿真)、OKF(VLA)、A2A(编排)——一源多投影
3. 运维:同一个文件在设备上(MCU)累积遥测 + PHM
4. 文件就是数字主线。无 sidecar 漂移。

谁受益?

• 机器人团队:一个工件替换漂移的文件夹
• 仿真平台(Newton、Isaac Lab、Gazebo):FLUXmeme 是 USD/MCAP 背后的单一源
• VLA / agent 初创:agent 无需运行时即可读资产
• 标准化导向:MIT、spec 优先、开放治理
