Robotics Fleet Management Integration

Overview

Integration Summary

Process Path and Robotics Fleet Management have a partnership for coordinating robotic picking and transport operations. Robots deliver pods to pick stations and transport totes between zones.

Capacity Coordination

Robot Fleet Impact on Routing

Process Path considers robot availability in routing decisions:

8
{
  "pathScoring": {
    "robotDependentPaths": ["AFE_ROBOTIC_PICK", "SPECIAL_HANDLING"],
    "currentRobotUtilization": 70,
    "robotCapacityScore": 80,
    "adjustment": "NORMAL"
  }
}

Robot Bottleneck Detection

If robot utilization > 90%:
1. Reduce routing to robot-dependent paths
2. Prefer conveyor-based transport
3. Alert Operations
4. Request additional robots from standby

WebSocket Integration

Real-time robot position updates via WebSocket:

// WebSocket connection for real-time updates
ws.onmessage = (event) => {
  const update = JSON.parse(event.data);
  if (update.type === 'ROBOT_POSITION') {
    // Update robot position on map
    // Track tote/shipment progress
  }
