At the higher end of the automation spectrum, mini-load and shuttle systems offer high throughput through large-scale racking solutions. Yet, they lack the flexibility that Automated Case Robots (ACRs) bring to the table.
Certain warehouse needs are better suited to mobile automation, while others align with fixed systems. The chart below outlines several components we’ll explore further.
Flexibility for Changing Order Profiles
Adaptability to shifting order profiles is critical to fulfillment center success. With consumers able to switch providers at the tap of a screen, maintaining delivery promises is more important than ever.
Automated systems like Autonomous Mobile Robots (AMRs) and shuttle systems excel at managing order variability. AMRs, in particular, are highly flexible and can be quickly deployed or integrated with fixed systems like shuttles. However, understanding order volume patterns is key to optimizing their use effectively.
High-Throughput Automation
High throughput is essential for maximizing efficiency in modern distribution centers. Fixed systems like shuttles are designed to deliver high throughput within a compact footprint.
Shuttles that can sequence orders within the block are especially valuable in e-commerce and retail, where dense order picking is crucial. While AMRs and ACRs offer scalability and fast deployment, achieving high throughput with them requires a larger number of bots—which can lead to congestion and reduced efficiency.
Adapting to Variable Business Growth
Mobile automation is ideal for businesses experiencing variable growth. AMRs can be easily scaled up or down and integrated with minimal disruption. Robot-as-a-Service (RaaS) models allow companies to “rent” additional robots during busy periods without committing to long-term capital investments.
Managing Peak-to-Average Volume Spikes
Retailers, especially in e-commerce, often deal with significant spikes in order volumes during peak seasons like Black Friday or Cyber Monday. AMRs can be cost-effectively deployed before peak periods to accelerate picking and transport tasks—enabling faster fulfillment and better customer service.
Supporting Mature Warehouse Processes
A mature warehouse process is defined by optimized efficiency, accuracy, and scalability. These warehouses often already utilize fixed automation systems and are well-positioned to integrate additional technologies like AMRs and AS/RS systems.
Combining fixed systems such as conveyors and shuttles with mobile technologies enhances overall agility without sacrificing performance.
Lower CAPEX Entry Point
Mobile automation generally requires less capital expenditure upfront. AMRs don’t demand extensive infrastructure changes like conveyors or high-density racking, significantly reducing setup costs.
However, as system complexity increases, AMR-based solutions can become more expensive and slower to implement. While they may never match the cost of large-scale shuttle systems, they also don’t offer the same throughput at scale.
Building Utilization Efficiency
Fixed automation typically delivers better building utilization, particularly in terms of:
For brownfield sites or existing facilities, AMR systems offer easier implementation due to minimal structural requirements.
Bringing Fixed and Mobile Automation Together
Integrating Automated Vehicles (AGVs, AMRs, and ACRs) with fixed systems can greatly enhance operational efficiency and flexibility. To do so effectively, it’s critical to:
Ultimately, success depends on partnering with experts who understand both your process flow and the full range of fixed and mobile technologies. This ensures you get a tailored solution—whether that’s an ADAPTO Shuttle system or a compact AMR network replacing traditional conveyors.
“Due to our trusted and long-standing relationship with Vanderlande, we had proven automated systems for low-volume, slow movers,” says Konrad Ott, Project Leader at Kaufland. “However, we wanted something similar for high-volume fast movers, and that’s why the STOREPICK ACP system [with fixed and mobile automation] was recommended to us.”
