Head to head
Doosan Robotics H2515 vs KUKA KR 20 R3100
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Heavy payload cobot for palletizing and handling
Extended reach robot for large envelope handling tasks
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The first question here is not specs but the cell: the Doosan Robotics H2515 is a collaborative arm designed for reduced-speed operation near people (fenceless only where an application risk assessment allows it), while the KUKA KR 20 R3100 is a 6-axis industrial arm that runs behind a guard at full speed. They run different controllers, the Doosan Robotics H2515 on the CS-02 (DC Controller) and the KUKA KR 20 R3100 on the KR C5, so whichever platform your team already programs and stocks parts for is a real tiebreaker. Mounting options differ: the Doosan Robotics H2515 lists Floor, and the KUKA KR 20 R3100 lists Floor, Ceiling, Wall, and Angle. Both are aimed at machine tending and material handling, with the Doosan Robotics H2515 stretching to collaborative assembly and palletizing and the KUKA KR 20 R3100 to packaging and dispensing.
Choose this one when
Job fit first, then the controller and cell constraints that decide which arm you can actually install.
Choose the Doosan Robotics H2515 when
- High payload for a collaborative robot
- Full reach industrial style envelope
- Joint torque sensing throughout the arm
- Suited to palletizing light to medium cases
Watch for
- Larger arm mass than lighter Doosan cobots
- Collaborative speed limits still apply at this payload
Choose the KUKA KR 20 R3100 when
- Exceptional reach for its payload class
- Good choice for servicing multiple stations
- Solid repeatability at full extension
- Ceiling mount option saves floor space
Watch for
- Long arm needs a rigid mounting structure
- Slower cycle times at full reach compared to shorter arms
Controller ecosystem
Programming habits, spare parts, and pendant familiarity often decide the pick when payloads are close.
- Brand
- Doosan
- Controller
- CS-02 (DC Controller)
- Class
- collaborative
Service, spares, and pendant training for the Doosan Robotics H2515 run through Doosan's CS-02 (DC Controller) stack.
- Brand
- KUKA
- Controller
- KR C5
- Class
- 6-axis industrial
Service, spares, and pendant training for the KUKA KR 20 R3100 run through KUKA's KR C5 stack.
These arms run different controllers (CS-02 (DC Controller) vs KR C5). If your team already programs one of them, retraining programmers and stocking a second set of spares usually costs more than a small payload or reach advantage on paper.
Mounting, footprint, and mass
How the arm can be oriented in the cell, and how much mass you have to mount.
| Field | Doosan Robotics H2515 | KUKA KR 20 R3100 |
|---|---|---|
| Mounting | Floor | Floor, Ceiling, Wall, and Angle |
| Robot mass | 70 kg | 549 kg |
| Protection (IP) | IP54 | IP65 |
Heavier arms want stiffer bases and more clearance around the swept volume, and they push freight and rigging costs up on the install. IP ratings only cover the section they name, so a wrist-only rating protects the wrist and nothing else; check the body rating separately before you commit the arm to a washdown or dusty cell.
Application fit

Speed and cycle-time planning
Speed is rarely a single datasheet number across brands. Use payload, reach, and class as the planning frame, then confirm cycle time in a path study.
The Doosan Robotics H2515 is a collaborative arm rated 25 kg at 1500 mm with ±0.1 mm repeatability. The KUKA KR 20 R3100 is a 6-axis industrial arm rated 20 kg at 3101 mm with ±0.05 mm. Class changes how speed shows up in a cell: collaborative arms slow down near people and can speed up in a guarded mode, while industrial arms run at rated speed inside a fence or scanner field. Which arm cycles faster on your part depends on the path, the payload, and the safeguarding, so confirm the takt with a path study before you quote it.
