Redpoint delivers SIL2-compliant RTLS for large-scale autonomous mobile robot environments
The Problem
Some AGV manufacturers deploy tens of thousands of robots every month in warehouse environments. While AGVs can increase productivity by up to 300%, safety protocols require the entire fleet to stop whenever human crews enter the area. This leads to frequent and costly shutdowns—especially in high-volume operations—creating tension between safety and efficiency.
The Solution
Redpoint’s RTLS makes crew locations visible to AGVs, enabling intelligent avoidance maneuvers and route adjustments. The system also feeds real-time data to central dispatch for smarter task allocation—ensuring worker safety without halting operations.
Technical Challenges
- High node density and mobility: Hundreds or even thousands of fast-moving AGVs operating simultaneously
- Extreme reliability: Required >99% system reliability for functional safety (SIL2), despite UWB’s low transmission power
Meeting SIL2 safety standards in wireless environments—especially at UWB’s low power levels—posed a serious engineering challenge.
The Results
Redpoint engineered purpose-built wireless protocols optimized for safety-critical environments. These protocols mitigate congestion and interference, while delivering:
- Centimeter-level accuracy
- Millisecond latency
- 99.5% reliability
