FANUC M-16iB/20 vs UR5e Cobot: $1,800 Arm-Only vs $21,000 Collaborative Robot

A $19,200 price gap separates a used FANUC M-16iB/20 arm-only from a Universal Robots UR5e cobot. Decide based on payload, setup effort, and whether you need collaborative features.

Last updated Aug 17, 2026

When you're choosing between industrial robotics cobots, the decision often comes down to payload and how much setup you're willing to do. The FANUC M-16iB/20 is a 2005 industrial robot arm priced at USD 1,800, while the Universal Robots UR5e is a used cobot priced at USD 21,000. That $19,200 gap is the clearest starting point, but the right pick depends on your workcell.

Quick verdict

Go with the FANUC M-16iB/20 if you need a heavy-duty arm and you can supply a controller, teach pendant, and cables yourself-it gives you a lot of robot for a much smaller outlay. Choose the UR5e if you prefer a collaborative arm with built-in force sensing and touchscreen programming, and you're comfortable with the higher cost.

Comparison table

| FANUC M-16iB/20 (used, 2005) | USD 1,800 | | 20 kg | 6 axes, 220 kg arm weight, arm only |

| Universal Robots UR5e (used) | USD 21,000 | | 5 kg | 6 joints, 850 mm reach, ±0.03 mm repeatability, force/torque sensor |

Where the FANUC M-16iB/20 wins

The FANUC's biggest advantage is its payload. It's rated for much heavier parts than the UR5e, making it the obvious pick for moving large workpieces or mounting heavy end-effectors. It also comes from a traditional industrial robot lineage, with six axes and a substantial build. If you already have the missing controller and teach pendant, this arm is a strong foundation for a fixed workcell.

Where the Universal Robots UR5e wins

The UR5e is built for collaboration and ease of use. Its six-axis design includes force-sensing capabilities, and programming happens through a 12-inch PolyScope touchscreen. You can hand-guide the arm to teach it moves, which shortens setup time for tasks like assembly, inspection, and lab automation. A compact footprint and flexible mounting make it easier to fit into existing workspaces.

Product notes

FANUC M-16iB/20 Industrial Robot Arm (A05B-1216-B202)

The FANUC M-16iB/20 is a used 2005 industrial robot arm with a 20 kg payload and six axes. It's sold as an arm only, so no controller, teach pendant, or cables are included. The strongest reason to choose it is that payload capacity-enough for heavy parts and tools-paired with the relatively low cost of the arm itself. The limitation is what's missing: you'll need to find compatible FANUC controller and pendant hardware separately, and the unit shows cosmetic wear and paint loss from prior industrial use.

Universal Robots UR5e Collaborative Robot

The Universal Robots UR5e is a used collaborative robot with a 5 kg payload and 850 mm reach. Its standout feature is the integrated force/torque sensor, which allows force-sensitive tasks like precision insertion and polishing. Programming is done through the 12-inch PolyScope touchscreen, and the arm can be hand-guided to teach waypoints. The reason to choose it is the combination of easy programming, safety-conscious collaboration, and a compact design that mounts in any orientation. The limitation is the price-it costs significantly more than the FANUC arm-and the 5 kg payload is lighter, so it's not suited for very heavy workpieces.

Final choice by use case

Pick the FANUC M-16iB/20 for heavy-payload tasks in a fixed cell when you already own the controller, pendant, and cables. Choose the UR5e for a collaborative, easy-to-program robot that handles medium-duty jobs with force sensitivity and flexibility.
