Real-time Teleop Infrastructure

Low-latency video streaming with multi-operator coordination. Remote robotics control across continents at under 200ms.

C++RustWebRTCRTOSgRPC

THE PROBLEM

Needed to enable human operators on one continent to control robots on another with latency low enough for fine manipulation tasks - under 200ms round-trip for video and control signals.

OUR APPROACH

We built custom WebRTC pipelines in C++ with hardware-accelerated encoding, paired with a Rust control channel that bypasses the video stack entirely for latency-critical commands. Multi-operator coordination uses a lock-based handoff protocol.

TECHNICAL DEPTH

01Custom WebRTC pipeline with hardware H.265 encoding

02Separate control channel in Rust for sub-frame latency

03Multi-operator handoff with distributed lock protocol

04Adaptive bitrate based on network condition estimation

05RTOS scheduling for deterministic control loop timing

OUTCOME

Running cross-continent operations at under 200ms. Multiple operators coordinating on shared robots simultaneously.
