4D pallet shuttle system operating inside a high-density automated warehouse grid
4D Shuttle AS/RS

Every pallet. Every level. Zero compromises.

The Rainbow Dynamics 4D Shuttle is a fully autonomous AS/RS that moves across lanes, aisles, and levels, handling loads up to 2,000 kg with exceptional speed, precision, and storage efficiency.

Four components.
One integrated system.

The 4D shuttle AS/RS is a collection of independent parts. It is a purpose-engineered ecosystem where each component is designed to work in unison.

4D Pallet Shuttle

The autonomous vehicle carrying up to 2,000 kg. Equipped with two independent wheel sets — 8 for lane direction, 4 for main aisle.

Integrated Lift

A rack-integrated lift handling loads up to 2,000 kg with 13.2 kW installed power and energy recuperation.

Standard Racking

Pallet shuttle racking system with customized rail profiles. No height loss from main rails or crossing profiles.

WMS + WCS Software Platform

Proprietary warehouse management and control software with a Digital Twin simulator, machine learning path optimization.

Designed for density. Built for throughput.

True 4D Movement

Shuttles travel along deep storage lanes, across main aisles, and between rack levels via integrated lift — without any manual intervention or re-positioning.

Max Space Utilization

Deep-lane storage with no aisle space wasted on forklift access. The compact racking structure eliminates height loss from rail crossings, maximizing every cubic meter.

5X Energy Efficiency

Electromechanical spindle-lifting, energy recuperation on the integrated lift, and opportunistic on-line charging ensure peak performance with a fraction of the power consumption.

3-Sec Direction Change

At every rack crossing, the shuttle's independent wheel sets swap orientation in 3 seconds. No turntables, no lifts between directions — just continuous flow.

Cold Store to Ambient

Operational from -25°C cold-store environments through to +40°C ambient conditions. The same shuttle hardware serves both requirements without modification.

WMS Compatibility

The proprietary WMS and WCS software stack connects via standard interface to any existing ERP or warehouse management system, eliminating costly rip-and-replace migrations.

Cold store, ambient, or
anything between.

Most pallet shuttle systems require different hardware for cold store, ambient, and everything in between. The 4D shuttle AS/RS is engineered to operate across the entire storage spectrum.

  • Lithium Iron Phosphate batteries maintain capacity across the full temperature range without degradation.
  • 100% rated performance in cold-store conditions with automatic charging maintaining continuous operation.
  • Galvanized racking certified for cold-store humidity and thermal cycling.
Operational Temperature Range

Full performance guaranteed across a 65°C span

-25°C Cold Store Minimum
+40°C Maximum Operating Temperature

Same hardware, same software, same performance — regardless of operating temperature.

Three Layers of Recovery.

Step 1 — Automatic Recovery

Software triggers the shuttle's self-recovery routine. The vehicle drives autonomously to the nearest maintenance point without operator intervention.

Step 2 — WiFi Remote Control

If automatic recovery cannot complete, an operator approaches with a WiFi remote and manually drives the shuttle to the maintenance area — no physical entry into the rack zone required.

Step 3 — Partial Shutdown & Manual Extraction

In the rare worst-case scenario, only the affected zone is paused. All other shuttles reroute around the blocked area. A technician extracts the unit manually with a spare shuttle deployed immediately.
