Are you facing these "pain points of heavy-load handling"?

Pain Point 1: Complex factory environment and difficulty in multi-robot collaborative avoidance

Multiple AGVs work alongside heavy-load equipment in the same area. Narrow passages and mixed flow of personnel and vehicles lead to frequent path conflicts and complex avoidance decisions among robots, which traditional scheduling systems struggle to handle.

Pain Point 2: High navigation accuracy requirement and difficulty guaranteeing positioning consistency

AGVs need precise docking at dense production stations with millimeter-level parking positioning accuracy. Traditional magnetic stripe or QR code navigation is prone to wear and high maintenance costs. Single navigation mode suffers poor reliability under complex lighting and ground reflection conditions.

Pain Point 3: Frequent signal interaction, and network stability becomes a bottleneck

Frequent operation signal exchanges between AGVs and on-site management systems (MES, WMS) impose high requirements on network real-time performance and stability. Once signal loss occurs, it may trigger task interruption, material mismatch and other cascading problems.

Pain Point 4: Large product size, unstable center of gravity and prominent operational safety hazards

Heavy products transferred on-site feature large dimensions and irregular shapes, making it hard to accurately predict the center of gravity. The inertial force generated during start-up, braking and steering under heavy load rises geometrically. Experimental data shows that the inertial impact during emergency stop under 10-ton load can reach more than 15 times of the normal load, bringing extremely high challenges to equipment operation stability and safety.
