Head to head
Universal Robots UR20 vs Universal Robots UR30
A specification duel across payload, reach, precision, and footprint, with a plain read on which arm suits which job.
Industrial reach cobot for heavier handling jobs
High payload cobot for heavy parts and pallets
Specification duel
Green marks the stronger figure. Unconfirmed specs are shown but not scored.
The verdict
The specs separate them here: the Universal Robots UR30 carries more, 30 kg to the Universal Robots UR20's 20 kg, and the Universal Robots UR20 reaches farther, 1750 mm to 1300 mm. Both run the Control Box controller, so programming, spare parts, and operator familiarity carry across either way. Mounting options differ: the Universal Robots UR20 lists Floor, Wall, Ceiling, and Any angle / tilted, and the Universal Robots UR30 lists Any.
Choose this one when
Job fit first, then the controller and cell constraints that decide which arm you can actually install.
Choose the Universal Robots UR20 when
- Long reach for a collaborative robot
- Higher payload than classic e-Series models
- Familiar UR programming for existing UR users
- Slimmer joint design improves access in tight cells
Watch for
- Larger footprint than UR's smaller cobots
- Newer platform with a shorter installed base track record
Choose the Universal Robots UR30 when
- 30 kg rated payload, with 35 kg allowed under UR's boundary conditions in the manual.
- 1300 mm reach broadens palletizing and machine tending envelopes compared with earlier UR models.
- ±0.1 mm pose repeatability per ISO 9283 for consistent pick and place.
- Mounts in any orientation and rated IP65 for typical shop floor use.
Watch for
- Rated payload is 30 kg; the 35 kg figure requires the boundary conditions in the UR manual, so review before quoting.
- Collaborative speed depends on the risk assessment, so expect fenceless cycle time to be slower than a caged industrial arm.
- 63.5 kg arm mass makes the UR30 heavier than smaller UR models; size any cart or pedestal accordingly.
Controller ecosystem
Programming habits, spare parts, and pendant familiarity often decide the pick when payloads are close.

Both arms run the Control Box controller, so pendant skills, program backups, and many spare parts carry over if you standardize on either model.
Mounting, footprint, and mass
How the arm can be oriented in the cell, and how much mass you have to mount.
| Field | Universal Robots UR20 | Universal Robots UR30 |
|---|---|---|
| Mounting | Floor, Wall, Ceiling, and Any angle / tilted | Any |
| Robot mass | 64 kg | 63.5 kg |
| Protection (IP) | IP65 | 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
Where each arm is aimed, based on the applications listed on its robot page.
Both pages list collaborative assembly, machine tending, material handling, and palletizing.

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 Universal Robots UR20 is a collaborative arm rated 20 kg at 1750 mm with ±0.1 mm repeatability. The Universal Robots UR30 is a collaborative arm rated 30 kg at 1300 mm with ±0.1 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.
