Software & Middleware

WebSocket

WebSocket is a full-duplex communication protocol over a single TCP connection, standardized as RFC 6455, that enables low-latency bidirectional messaging between clients and servers after an HTTP upgrade handshake. Robotics systems use it for browser-based dashboards, remote monitoring, and teleoperation front ends, most notably through rosbridge, which exposes ROS topics, services, and actions to web clients as JSON over WebSocket.

Why it matters for physical AI

Web-native transport lets operators supervise and teleoperate robots from any browser without installing middleware, which is how most fleet dashboards and remote intervention interfaces for deployed robots are built.
