The KEENON S300 is a heavy-load intelligent delivery robot with a 300 kg lifting capacity, featuring an industry-low 23 cm chassis with a lifting platform that handles shelves up to 120 by 120 cm using a shelfless structure. It supports multiple intelligent delivery modes including loop, direct, multi-point, and transport. LiDAR SLAM combined with stereo vision fusion enables dynamic auto-planning with millisecond-level route recalculation for obstacle avoidance. On-device path planning allows offline operation without central control or external networks. Up to 6 hours of full-load runtime with 3.5-hour fast charging, supporting automatic charging, manual charging, and battery swap. A 360-degree safety system combines 3D vision, dual LiDAR, VSLAM, and triple emergency stops. Targets industrial logistics and warehouse material handling.
