Which Model C2 Fits Your Facility? Quasi AMR Cart Comparison

AMR Cart Comparison: Which Model C2 Is Right for Your Facility?

Choosing an autonomous mobile robot is rarely just a payload decision. It’s a workflow decision — aisle widths, material type, delivery frequency, what gets handed off where, and which routes are actually causing pain today. If you get those wrong, the spec sheet won’t matter.

The Model C2 lineup was built around this reality. Instead of forcing every facility into a single robot format, Quasi offers four configurations on the same autonomous platform: Mini, Standard, Large, and PartPorter. This AMR cart comparison walks through how to match each one to the work it’s actually good at — and where a mixed fleet usually beats picking just one.

Quick AMR Cart Comparison Table

All four share the same 41.5″ overall height, the same rechargeable lithium-ion battery, fast charging to 50% in about an hour, and up to 16 hours of runtime depending on duty cycle. The chassis and intelligence are common across the lineup — what changes is the shelf, the payload ceiling, and the footprint.

C2 Mini: The Tight-Space Specialist

The C2 Mini is the smallest robot in the lineup and the right call when space — not weight — is the constraint.

The Mini is best suited for:

• Small parts and lab supply delivery
• Compact manufacturing cells with multi-sided workstation access
• Narrow aisles where a Standard or Large would have to slow down or replan
• High-frequency, short-distance loops

With a 14.6″ × 14.6″ shelf, a 150 lb payload ceiling, and a 2.5-foot minimum aisle, the Mini fits places larger AMRs simply can’t. The square chassis supports zero-radius turns, which matters in dense workcells where every pivot point counts.

Pick the Mini when the limiting factor on your floor isn’t how much the robot can carry, but whether the robot can get there at all.

C2 Standard: The Everyday Workhorse

If you only deploy one configuration, this is usually it. The C2 Standard is built for the kind of internal delivery that happens hundreds of times a day across manufacturing, healthcare, and lab environments.

The Standard is best suited for:

• Totes, bins, and work-in-process materials
• Tools and parts replenishment
• Lightweight finished goods
• General-purpose internal delivery routes across manufacturing, warehouse, and lab settings

It runs a 24.4″ × 14.6″ shelf, a 175 lb payload ceiling, and a 3-foot minimum aisle — wide enough for most modern facility layouts without forcing a floor redesign. But it’s real advantage is balanced efficiency. It carries more than the Mini, fits more places than the Large, and handles the broadest range of common material handling tasks. For most first deployments, it’s the model that gives you the fastest path to a working pilot.

Pick the Standard when you want one versatile robot that handles 80% of routine transport without overthinking the spec.

C2 Large: Higher Capacity, Fewer Trips

The C2 Large is what you reach for when the bottleneck is trips per shift, not access. The Large is best suited for:

• Larger totes and oversized bins
• Consolidated loads that a Standard would split across multiple runs
• Multi-stop delivery loops and longer routes
• Higher-throughput facilities with wider aisles

With a 32.25″ × 20.5″ shelf, a 225 lb payload ceiling, and a 4-foot aisle minimum, the Large carries more material per cycle and reduces the round trips required to keep a line fed.

Pick the Large when aisle width isn’t a constraint and you want to consolidate more material into each delivery.

C2 PartPorter: Built for Panels and Sheet Goods

The C2 PartPorter is the most specialized robot in the lineup, and the only cart-style AMR on the market purpose-built for flat, large-format materials. It uses the same 32.25″ × 20.5″ footprint as the Large but increases payload allowance to 250 lb and requires a 5-foot minimum aisle to account for permitted overhang.

The differences are in the frame, not just the dimensions:

• Open-back design for easier loading of sheet goods, panels, and drywall
• Optional dividers to protect finished or painted surfaces in transit
• Numbered compartments for pre-sorted assembly kits

Cabinet shops, woodworking operations, drywall fabricators, and any facility moving job-specific kits to assembly cells are the natural fit. If you’ve ever watched two people awkwardly carry a sheet of plywood across a shop floor, PartPorter is the robot that exists because of that moment.

Pick the PartPorter when the material itself — flat, bulky, finished, or delicate — is what’s making manual transport painful.

How to Decide: Start With the Workflow, Not the Spec

The fastest way to land on the right configuration is to work backward from the route, not forward from the catalog.

1. What are you moving?

• Small parts, cases, lab supplies → Mini
• Totes, bins, tools, everyday WIP → Standard
• Bulky bins, heavier loads, consolidated runs → Large
• Panels, sheet goods, organized kits → PartPorter

2. What’s your narrowest aisle?

Aisle width is the most common deal-breaker, so check it first:

• 2.5 ft → Mini only
• 3 ft → Mini or Standard
• 4 ft → Mini, Standard, or Large
• 5+ ft → Any model

If your facility has mixed environments — tight production cells and wide main aisles — that’s usually a signal that a mixed fleet will outperform any single-model deployment.

3. How often are deliveries happening?

• Many short trips → Mini or Standard, where speed and footprint matter more than load size
• Fewer, larger trips → Large or PartPorter, where consolidation reduces total robot-hours and frees up route capacity

4. Is the material itself the problem?

• Finished panels, painted surfaces, or fragile sheet goods → PartPorter (designed around protecting the load)
• Pre-organized kits that need separation and numbered compartments → PartPorter
• Material weight is the issue, not material type → Large (carries similar weight without the specialized frame)

Final Recommendation: One Platform, Several Configurations

The practical advantage of a lineup approach is that you don’t have to standardize on one robot for everything. A real-world deployment might look like:

• Mini units running tight production cells
• Standard units handling general internal delivery
• Large units consolidating high-volume routes
• PartPorter units serving the panel or kit-staging area

All four run on Quasi’s Q.AI intelligence platform, share the same charging infrastructure, and are managed through the same Cloud Connect interface for route building, navigation zones, map visualization, and fleet metrics. Mixing configurations doesn’t mean managing four different systems — it means matching the robot to the work without changing the operating model behind it.

The Bottom Line

The right AMR cart comparison isn’t a side-by-side of specs — it’s a side-by-side of your routes. Aisle width, material type, and trip frequency decide the model before payload ever enters the conversation. Most facilities that get the configuration right on the first deployment did it by walking the floor with a stopwatch, not by reading a brochure.

If you can describe one painful route in your facility in a sentence, you can probably narrow the C2 lineup to one or two configurations in the same breath.
