How We Built a Robot Mesh Network Using XMTP and x402

Robots today speak thousands of proprietary languages. ROS topics. Vendor SDKs. Custom REST APIs. Each one incompatible with the next. AI agents have no standard way to: Discover what robots are available and what they can do Commission a task with a guaranteed atomic payment Receive a standardized result regardless of hardware So I built one. RTP — Robot Task Protocol is an open standard that sits between AI agents and physical robots. It defines a common task envelope, capability vocabulary, payment flow, and lifecycle state machine that works across any robot hardware, connection type, or manufacturer. The payment layer is x402 — the emerging HTTP payment standard from Coinbase. No subscriptions. No invoices. An agent pays USDC, a robot moves. Atomic, on-chain, instant. The Problem in One Sentence There is no standard way for an AI agent to hire a robot and pay for it programmatically. That seems like a gap that should have been filled by now. It hasn't. Every robot integration is c
