A Four-Way Shuttle is an intelligent warehousing and logistics device capable of bidirectional movement (forward/backward, left/right) on a horizontal plane. It operates as an autonomous robot, typically integrated with lifts and racking systems to enable 3D automated storage.

vs. AGVs: Four-way shuttles run on fixed tracks, offering higher speed, more precise positioning, and simpler control than AGV systems.
vs. Stacker Cranes: Unlike stacker cranes limited to linear movement, four-way shuttles navigate horizontally and switch layers via lifts, providing superior flexibility and adaptability.
Equipped with two independent wheel systems (X/Y-axis), enabling agile navigation in complex warehouse layouts.
Uses wheel-system switching + real-time positioning to change directions. Integrates with lifts for cross-layer operations.
Non-vehicle mode: Lifts only transport goods; shuttles return to origin after tasks.
Vehicle mode: Shuttles enter lifts with goods, reducing transfer steps and boosting efficiency.
Ideal for irregular layouts or high-throughput warehouses. Scalable fleet size optimizes system capacity.
Managed by WCS/WMS for path optimization, dynamic obstacle avoidance, and real-time scheduling.

Wireless: Wi-Fi/Bluetooth/Zigbee for real-time control (flexible but latency-sensitive).
Wired: Ethernet/RS485 for stable, high-reliability scenarios.
Fieldbus: CAN/Modbus for real-time device control.
Cloud: IoT-enabled remote monitoring and data analytics.
Mecanum/Omni Wheels for omnidirectional movement.
Differential Steering + 4-Wheel Independent Control for precision.
