In the complex workshop of an Italian metal processing plant, Woxiaobai utilizes multi-sensor fusion technology to flexibly avoid obstacles in narrow spaces, and efficiently processes oil stains and metal debris with its powerful cleaning module, creating a healthier working space for employees while ensuring the production environment. Moving to the municipal streets of the high-temperature ancient city in Saudi Arabia, it has successfully responded to extreme weather conditions exceeding 40 ℃ per day. Through intelligent path planning and staggered operation modes, it provides a smart solution of "technology+environmental protection" for traditional cleaning modes without interfering with urban operations. At the Adelaide Basketball Tournament Center in Australia, its nearly 10 hour long battery life and fast response capability ensure the rapid cleaning of large areas of the venue and efficient turnover of activities after the game, and can customize cleaning strategies for different ground materials. At Singapore Changi Airport, the world's top aviation hub, Woxiaobai has demonstrated its outstanding ability to handle high passenger flow. Through 360 ° blind spot free operations, it safely shuttles through dense crowds and combines 24-hour unmanned operation and automatic supply systems to increase cleaning efficiency by 200%, completely breaking the time limit of manual cleaning.
