Reinventing PCB Logistics: How SEER Robotics Enables Fully Unmanned, High-Density Smart Manufacturing

In the fast-paced PCB manufacturing industry, high-density storage, unmanned logistics, and fully automated production environments are quickly becoming essential. SEER Robotics, together with Yihong Technology, has delivered a factory-wide intelligent logistics transformation—showing how advanced autonomous mobile robots and industrial automation systems can break long-standing logistics bottlenecks and reshape operational efficiency.

The customized solution integrates bin robots, robotic forklifts, and lifting transfer robots into a unified multi-floor logistics network, enabling the client to Build your own robot fleet within days and reach new levels of intelligent manufacturing performance.


Background: PCB Logistics Challenges Slowing Growth


As Yihong Technology expanded production, their original plant layout and manual workflows could no longer keep up. Key limitations emerged:

  • Limited Production Expansion
Manual picking and handling slowed throughput and constrained capacity.

  • Insufficient Storage Space
A decentralized warehouse layout resulted in low space utilization and inadequate storage for growing raw material and finished-goods volumes.

  • High Labor Costs and Rising Errors
Manual operations were labor-intensive, slow to respond, and prone to mistakes that threatened product stability.

These challenges made automated material handling and warehouse automation a necessity.


SEER Robotics’ Plant-Wide Intelligent Logistics Solution


To address space, efficiency, and labor constraints in the new factory, Yihong Technology partnered with SEER Robotics to deploy a full-process automation solution covering the raw material warehouse, production workshop, and finished-goods warehouse.

Powered by the Nebula Platform and orchestrated by the M4 Smart Logistics Management System, three types of robots work collaboratively to form a flexible, autonomous, multi-floor logistics network:

Bin Robots

Located on the third-floor raw material warehouse, they automate raw material access, workstation replenishment, and “last-meter” picking.

Lifting Transfer Robots

Responsible for cross-floor transport, these robots autonomously utilize elevators, linking the third-floor warehouse directly to the fourth-floor PCB production line.

Autonomous Forklifts

Deployed between the first-floor finished product warehouse and the third-floor raw material warehouse, they manage bulk pallet transfer, inbound/outbound tasks, and continuous replenishment.

This seamless integration eliminates manual handling and enables a truly unmanned logistics operation.


Key Highlights: Unlocking High-Density, Fully Autonomous PCB Logistics


1. Mixed Bin–Pallet Storage Design Boosts Space Utilization by Over 50%

To solve space shortages, SEER Robotics introduced an innovative upper-bin + lower-pallet mixed storage design, enabling layered storage in the same footprint.

Benefits:

  • Supports both high-volume pallet storage and small-batch bins
  • Reduces construction costs
  • Increases density and warehouse automation capacity
  • Delivers “large storage in a compact space”

This design creates a high-density warehouse suited for modern PCB material flows.


2. Multi-Robot, Multi-Floor Collaboration Creates a Fully Intelligent Logistics Network


The M4 system orchestrates complex scheduling across floors and robot types using intelligent hybrid algorithms.

Key capabilities:

  • Dynamic speed adjustments for overlapping robot routes
  • Automatic sequencing to avoid traffic congestion or deadlocks
  • Built-in interaction with factory equipment such as elevators and air-shower doors
  • Real-time coordination among AMRs, robotic forklifts, and lifting robots

The result:
Manual picking is eliminated, and core logistics are now 100% automated.

Cross-floor transfers that once took hours now take minutes, significantly boosting operational tempo.


3. End-to-End Digital Management Drives a Complete Smart Manufacturing Upgrade


Through seamless integration with the MES system, M4 synchronizes production planning with intelligent logistics.

The system enables:

  • Real-time robot task tracking
  • Path and traffic visibility
  • Accurate multi-type material management
  • Live inventory updates
  • Full traceability from raw materials inbound to finished goods outbound

This comprehensive digital transformation increases plant-wide operational efficiency by over 40%.


Value Delivered: A New Benchmark for PCB Industry Automation


SEER Robotics’ one-stop solution brings Yihong Technology:

  • A high-density warehouse aligned with modern PCB production needs
  • Fully unmanned cross-floor logistics
  • Higher production throughput and stable quality
