Recently, the ultra-high-level automatic inventory robot customized by our company for Unilever Argentina has completed on-site commissioning and official delivery, being fully deployed in the large-scale warehousing center of Unilever Argentina. Capable of full-automatic inspection for 14-meter-high shelves, precise QR code recognition and automatic entry and filing of inventory data, the equipment completely replaces the traditional manual high-altitude inventory mode, empowering the world-renowned FMCG giant to realize intelligent, efficient and safe upgrading of warehouse inventory. The successful delivery of this high-end overseas project not only demonstrates our company's robust R&D and on-site implementation capabilities in the field of intelligent warehousing robots, but also records an inspiring story of technological innovation and perseverance across thousands of miles.
Tackling an Ultra-High-Difficulty Customized Project to Solve Industry Pain Points
As a globally famous FMCG brand, Unilever Argentina operates a large-scale warehouse with massive stock, ultra-high shelves and a wide variety of goods, which has long been plagued by prominent pain points in traditional inventory management. In the past, warehouse inventory relied entirely on manual high-altitude operations. The 14-meter-high shelves far exceed the operating range of conventional lifting equipment. Staff had to conduct inventory layer by layer with simple lifting devices, resulting in extremely low efficiency - a full warehouse inventory would take several days. Meanwhile, manual QR code scanning and manual data registration led to high error rates, frequent omissions, incorrect records and inconsistent accounts with actual stock, seriously restricting warehouse turnover and supply chain efficiency.
To thoroughly address these warehousing inventory challenges, Unilever Argentina publicly recruited technical partners and put forward stringent customized requirements: building an independent lifting device based on an AGV mobile chassis to achieve stable lifting up to 14 meters without shaking or offsetting; equipping multi-section lifting structures with high-definition camera recognition modules to accurately capture QR codes on shelves at different heights and realize full-automatic and all-dimensional inventory counting.
Upon release, the requirement was regarded as an industry technical bottleneck. Many senior domestic robot manufacturers abandoned the project after on-site evaluation. Industry experts generally concluded that conventional AGV chassis has limited load-bearing capacity and stability, and a 14-meter ultra-high lifting structure would inevitably generate center-of-gravity offset and shaking during movement and lifting switching, making it impossible to meet the precise scanning requirements - deeming it an "impossible task".
Defying All Odds to Overcome Core Technical Barriers Through Iterative Optimization
Facing widespread industry doubts and rigorous technical standards, adhering to the corporate philosophy of "pioneering breakthroughs, tackling difficulties and honoring commitments", our company took on this customized project resolutely. We immediately assembled a core expert team covering R&D, structural design, electronic control commissioning and algorithm development to set up a special project group, holding overnight technical seminars to sort out core difficulties and deduce feasible solutions.
In the early stage of the project, the R&D team confronted two major technical bottlenecks. First, the balance control of the 14-meter ultra-high lifting structure. The higher the lifting height, the harder it was to stabilize the chassis, and slight shaking would cause blurry scanning and recognition failure. Second, the coordinated operation of multi-section cameras. Varying light conditions and shooting angles at different heights required adaptive dynamic recognition algorithms to ensure full-height recognition accuracy.
The project team rejected 6 preliminary design schemes and abandoned the traditional single lifting structure. We innovatively adopted a segmented lightweight lifting architecture and dynamic center-of-gravity adaptive adjustment system. By optimizing chassis counterweight, installing intelligent anti-shake damping devices and real-time attitude monitoring sensors, the system can dynamically correct equipment operation deviations. Meanwhile, independent high-definition anti-shake cameras were configured for each lifting section. Matched with self-optimized AI intelligent recognition algorithms, the equipment can automatically adapt to varying light intensities and correct shooting angles, ensuring high-precision QR code recognition at all heights.
Numerous problems emerged during the prototype trial production stage. The first-generation prototype suffered from frequent jittering when lifting above 10 meters, with a scanning failure rate of up to 30%. Offset occurred during speed switching, and poor coordination between chassis movement and lifting was observed. In addition, simultaneous operation of multiple cameras caused signal interference and data delay. Faced with these technical challenges, the team worked around the clock in the laboratory to adjust parameters, optimize structures and iterate algorithms. After hundreds of stability tests and dozens of structural upgrades, we successfully solved core problems including anti-shake control, dynamic balance, precise recognition and data synchronization. The final optimized prototype fully met all customer technical specifications.
Overcoming Multiple Hardships for Overseas Delivery Across Half the Globe
While technical research and development obstacles were overcome, the on-site delivery brought unprecedented challenges. As one of the farthest countries from China, Argentina requires a flight of over 20,000 kilometers lasting nearly 40 hours. Long-distance travel, severe jet lag and drastic environmental differences created huge obstacles for on-site commissioning.
To ensure on-time delivery, two core engineers volunteered for the overseas mission. Affected by prolonged sitting, frequent air pressure changes and extreme jet lag during the ultra-long flight, one engineer suffered a spontaneous pneumothorax and was hospitalized immediately after landing. Despite incomplete recovery, he insisted on returning to the project site to guarantee progress.
Coinciding with the Argentina World Cup period, local work efficiency dropped significantly as residents focused on the tournament. Clients had low coordination willingness, leading to slow progress in equipment entry, site docking and authority activation. Furthermore, language barriers and differing working habits further hindered installation and commissioning, bringing the project to a standstill at one point.
Undeterred by physical ailments, geographical barriers, language gaps and delayed progress, our team took proactive countermeasures. We bridged communication obstacles via translation tools, hand-drawn operation diagrams and on-site demonstration. To catch up with the delayed schedule, we adjusted working hours to adapt to local routines and worked overtime continuously. The team conducted in-depth docking of warehouse conditions, equipment parameters and system ports to eliminate adaptation faults, completing full-process debugging and trial operation through round-the-clock on-site work.
Successful Delivery Wins High Praise, Empowering Global Intelligent Manufacturing
After dozens of days of arduous overseas work, our team overcame all difficulties and completed the full process of equipment installation, commissioning and trial operation. At present, the intelligent inventory robots have been officially put into stable operation at Unilever Argentina's warehouse. Capable of autonomous route planning, automatic lifting inspection and 24/7 unmanned operation, the robots achieve full coverage of 14-meter-high shelves with 100% inventory accuracy. The inventory efficiency is more than 8 times higher than that of manual work, completely solving the customer's long-standing warehousing pain points, greatly reducing labor costs and operational safety risks, and comprehensively improving intelligent warehouse management capabilities.
