Robots Communicate Directly Without a Server Distributed Traffic Control System

Navi-V2V is a distributed traffic control system where robots communicate directly (DSRC/UDP) without a central server to perform collision avoidance and traffic coordination. A 48% takt time reduction compared to third-party ACS was verified in an automotive manufacturing POC.

Key Features

4 features

Zero Server Dependency

Direct robot-to-robot communication (DSRC/UDP) maintains cooperative driving even during server failure or Wi-Fi shadow zones. Structurally eliminates the single point of failure of centralized control.

2-Stage Collision Detection (OBB+SAT)

Two-stage structure of OBB-based trajectory prediction screening followed by SAT precision determination concentrates control only where real collision risk exists. Minimizes unnecessary stops.

5-Level Priority Decision

Entry status → task type → arrival time → occupancy time → robot ID: 5-level criteria that structurally block deadlocks and determine optimal passage order.

Dual Safety Net with Navi-Brain

Dual safety net where Navi-Brain (global optimization) and V2V (local collision prevention) complement each other, maximizing operational stability in large-scale deployments.

POC Verified: 48% Takt Time Reduction vs. Third-Party ACS

Validated 12 scenarios in an actual automotive manufacturing environment. OBB+SAT trajectory-based control fundamentally improved intersection throughput efficiency over zone-locking methods, reducing total takt time from 27:44 to 14:17. Zero collisions recorded in 24-hour continuous operation with 35 robots.

  • 48% takt time reduction (27:44 → 14:17)
  • Zero collisions in 24-hour continuous operation with 35 robots
  • All 12 scenario types passed (merge/cross/detour/comm cycle)

Third-Party Compatibility: Add as a Layer Without Replacing Existing ACS

The V2V communication protocol is designed to be compatible not only with Navifra autonomous navigation SW but also with third-party robot control systems. Simply attach a V2V Client to existing robots for immediate application. Deployment time is 1-2 days for existing Navi-Core/Brain environments, within 1 week for new sites.

  • Protocol compatible with third-party ACS and autonomous navigation SW
  • Apply by simply adding V2V Client to existing robots
  • Built-in platooning and detour driving
  • V2IO: direct interlock with conveyor, gate, and process equipment
