Automated Tote Box Delivery System for Large Semiconductor Plant

Automated FOUP Handling and Delivery

SESTO’s AMRs equipped with shelves automate the transportation of heavy tote boxes across long distances—up to 40 km per day—within a large semiconductor manufacturing facility in China. By replacing manual material movement with autonomous delivery, the system enhances productivity, operator safety, and traceability across clean production environments.

Previously, operators carried heavy tote boxes manually between departments, which caused fatigue and injury risks. Since deployment, SESTO’s AMRs have enabled continuous operations while freeing operators to focus on higher-value tasks.

Challenges
  • Deliveries covered long distances of up to 40 km per day.
  • Heavy tote boxes were manually transported, causing operator fatigue.
  • Manual handling led to workplace injuries and productivity loss.
  • The customer required higher plant throughput to stay competitive in the semiconductor sector.
Solutions
  • Automated transport: Ten SESTO AMRs equipped with shelving modules deliver heavy totes efficiently across multiple production zones.
  • High endurance: Each AMR covers up to 40 km daily with reliable performance in a large facility.
  • Coordinated logistics: Fleet management system ensures dynamic routing and task allocation across all AMRs.
  • Traceable operations: Real-time tracking of tote movement enhances visibility and process control.
  • Proven deployment: The solution has been operational since 2017 with consistent uptime and safety performance.

 

Outcome
  • Reduced manual workload: Operators are relieved from long-distance carrying tasks.
  • Enhanced workplace safety: Fatigue and injury risks have been minimized.
  • Increased plant productivity: Continuous automation supports higher output with fewer delays.
  • Reliable performance: SESTO AMRs maintain consistent delivery schedules across shifts.
  • Operational longevity: Over seven years of sustained, reliable operation demonstrate long-term system stability.
