The SMT material handling robot is an intelligent autonomous transport solution designed for SMT production lines. It enables automated loading and unloading of material racks and supports line-side buffering and turnover for PCBs, electronic components, and SMT reels.Powered by 3D LiDAR SLAM navigation, the robot uses natural feature-based mapping and localization without the need for tracks or reflectors. It ensures quick deployment, reliable autonomous navigation, and safe obstacle avoidance in dynamic factory environments.With multi-robot coordination, the system supports cross-area operations and bidirectional material transfer between SMT lines and buffer zones, helping prevent congestion and improve logistics efficiency. It also integrates with MES/WMS systems for real-time data exchange and material traceability.
