Binary WebSocket Protocol
We stream compact binary buffers for joint telemetry, reducing JSON parsing overhead by 85%.
Building Real-Time Web HMIs for Industrial Robots: Our Frontend Architecture
In industrial automation, traditional robot teaching pendants rely on proprietary legacy screens. At Mujin, we replaced dedicated hardware screens with high-performance, web-based Human-Machine Interfaces (HMIs) running directly on modern browsers.
Key Challenges in Robot HMI Engineering
Section titled “Key Challenges in Robot HMI Engineering”- Sub-10ms Latency Requirements: Teleoperating an industrial robot arm requires instant visual feedback without frame drops.
- Heavy 3D Render Workloads: Visualizing real-time point clouds, robot joint angles, and safety zones.
- Cross-Platform & Offline Reliability: Operating reliably on warehouse touch monitors, tablets, and ruggedized industrial hardware.
