Unlock new material handling workflows and improve productivity with the OTTO 600 Cart

Manual material handling can consume about 25% of the workforce, 55% of the factory floor and 87% of the time of production in a factory. This inefficiency not only strains workers but also limits throughput and predictability, especially in dynamic manufacturing environments.

OTTO 600—a tough and nimble midsize autonomous mobile robot (AMR)—addresses these challenges by moving up to 600 kg in high-traffic, tight spaces at industry-leading average speeds. With the addition of its new cart attachment—which the OTTO 600 can autonomously dock with—manufacturers can unlock new workflows that maximize uptime, improve productivity, and optimize floor space.

Maximized uptime: The OTTO 600 Cart enables faster deployment without the need for fixed infrastructure changes, ideal for environments with limited production shutdown windows. Capable of autonomous payload pick-up and drop-off, as well as opportunistic charging—even while the cart is engaged—the attachment helps reduce idle time and maintains continuous operation across shifts.
Improved productivity: With a 420 kg (926 lb) payload capacity, the OTTO 600 Cart standardizes the handoff interface between the AMR and key areas like kitting zones, production lines, and storage. It also supports multi-drop routes, enabling a single AMR to service multiple stations in one run. Dispatch AMRs with a schedule or a trigger to keep material flow in sync with takt time—ensuring materials arrive exactly when they’re needed.
Optimize facility floor space: The OTTO 600 Cart functions as a portable P&D stand and maintains a compact footprint even with the cart engaged, eliminating the need to widen aisles or modify facility infrastructure. Its three cart configurations support various workflows, enabling one AMR fleet to handle multiple tasks. By enabling reliable, Just-in-Time (JIT) deliveries, the cart reduces buffer inventory requirements—freeing up valuable floor space and tightening production cycles.

Discover how these capabilities come together to unlock three new material handling workflows.

1. Delivering heavy parts to the lineside

In this workflow, the OTTO 600 Cart transports pallets and totes loaded with heavy components directly to the lineside. The AMR autonomously cycles between staging areas or work cells and production zones, exchanging empty carts for full ones to sustain a continuous inflow of parts. By reducing reliance on unsafe and inefficient forklift-based manual material transport, this workflow keeps line throughput consistent with reliable, JIT deliveries that minimize the risk of part shortages.

2. Delivering sequenced kits to assembly stations

In this workflow, the OTTO 600 Cart, equipped with a handle, is preloaded with part kits sequenced for a specific product and delivered by the mobile robot to designated assembly stations. The cart is dropped off by the AMR and manually pushed through different staging areas in the sequencing cell, enabling efficient picking and organization before transport. By streamlining complex assembly processes, manufacturers can minimize lineside inventory, reduce picking errors, and ensure components arrive in the precise order required for efficient assembly. This workflow is common in the automotive industry, where it supports built-to-order production models.

3. Transporting Work-in-Progress (WIP) goods

In this workflow, OTTO 600 moves the cart containing partially assembled components between workstations, or from sub-assembly lines to final assembly. By automating the mid-process movement of heavy WIP materials, manufacturers can maintain consistent production flow, reduce ergonomic strain on workers, and improve overall process reliability. This approach also supports modular manufacturing strategies by enabling flexible routing of assemblies based on real-time production needs.
