- Six current models: UR3e (3 kg) through UR30 (30 kg), all 6-axis, all using the same PolyScope controller.
- Robot-only prices range from roughly $25,000 (UR3e) to $65,000 (UR30); full installed system cost is 2–3× that figure.
- UR+ marketplace lists over 300 certified accessories — grippers, vision systems, software — with plug-and-play URCap integration.
- Force/torque sensing is built in to every e-Series joint, enabling compliant assembly and safe human collaboration without extra hardware.
- Repeatability is ±0.03 mm (UR3e/UR5e) to ±0.05 mm (UR10e and above) — adequate for assembly but not precision machining.
Brand Overview
Universal Robots was founded in Odense, Denmark in 2005 and acquired by Teradyne in 2015. It pioneered the "collaborative robot" category by shipping robots that did not legally require a safety cage in many applications — the first to earn that distinction in production environments. The company's PolyScope teach pendant and waypoint-based programming made cobots accessible to manufacturers without dedicated robotics programmers.
As of 2026, UR cobots are installed in over 100,000 locations across 80+ countries. The e-Series (introduced 2018) is the current generation, adding built-in force/torque sensing, a new interface, and improved safety certification. A next-generation platform is expected post-2026.

Key Features of the e-Series
Built-in Force/Torque Sensing
All six joints contain torque sensors that feed back to the controller in real time. This enables power-and-force-limiting (PFL) safety mode — the robot stops if it senses unexpected contact. It also enables compliant insertion (searching for a hole to insert a pin), push-to-teach programming, and screwdriving with torque feedback, without adding an external force-torque sensor.
PolyScope 5 Controller
Universal Robots' proprietary controller software runs on a 12-inch touchscreen pendant. Programming uses a graphical waypoint editor — operators drag robot waypoints rather than writing code. Polyscope also supports URScript (a Python-like text language) for advanced users, and the PolyScope XML SDK allows third-party URCap plugins to extend the interface. A single UR controller manages one robot arm; multi-arm coordination requires external orchestration.
Safety Configuration
The e-Series supports 17 configurable safety functions including joint speed limits, TCP force limits, momentum limits, and configurable safety planes. All parameters are password-protected and logged. The safety system is TÜV-certified to PL d, Cat. 3 (ISO 13849-1), matching the standard required for close-proximity human collaboration.
Tool Flange I/O
Every e-Series robot has I/O at the tool flange (2× digital in, 2× digital out, 1× analog in, 1× analog out, 1× 24V power, 1× 0V) plus a built-in accelerometer. This allows many simple EOAT devices to run without a separate I/O junction box — reducing wiring complexity on the arm.
Applications by Industry
| Industry | Typical Task | Best Model | Key Consideration |
|---|---|---|---|
| Electronics / EMS | PCB handling, screw-driving, inspection | UR3e, UR5e | Repeatability ±0.03 mm meets most PCB requirements; clean room capable with IP54 |
| Metal fabrication | Machine tending (CNC lathe, mill), deburring | UR10e, UR16e | Coolant and chip ingress management; double-gripper for load/unload |
| Food & beverage | Packaging, pick-and-place, palletizing | UR10e, UR20, UR30 | IP54 standard; food-grade grippers required; palletizing cycle rate typically 6–10/min |
| Plastics | Injection moulding extraction, assembly | UR5e, UR10e | Hot part handling; integration with moulding machine via M-code or digital I/O |
| Assembly | Press-fit, screw-driving, dispensing | UR5e, UR10e | Built-in force sensing eliminates need for external FT sensor in most cases |
| Welding | MIG seam welding, torch manipulation | UR10e | Welding URCap available; most integrators use UR10e with Fronius, Lincoln, or Miller |
UR+ Ecosystem
UR+ is Universal Robots' certified accessory marketplace. As of September 2026 it lists over 300 products from 200+ partners. Certified UR+ products:
- Install via a URCap plugin — the accessory's controls appear natively in PolyScope
- Are validated for electrical and mechanical compatibility
- Ship with configuration files that automatically set joint speed limits if the accessory changes the robot's dynamic model
Key UR+ categories: grippers (Robotiq 2F-85/140, OnRobot RG2/RG6, Schunk), vision (Cognex, Keyence, Pickit 3D), force/torque (Robotiq FT 300), welding (Fronius, Lincoln), and software (Wandelbots, Energid).
The breadth of UR+ is a genuine competitive advantage: selecting a UR robot means access to the largest certified accessory library of any cobot platform. Competing platforms typically have 30–80 certified accessories.
Strengths and Limitations
Strengths
- Largest cobot market share — easiest to find integrators, training, second-hand units, and support
- UR+ ecosystem: 300+ certified accessories with plug-and-play software integration
- PolyScope is widely taught — large pool of operators already familiar with the interface
- Built-in FT sensing on all models without extra cost
- Broad model range covers 3–30 kg without changing controller or ecosystem
- Strong safety certification (PL d, Cat. 3)
Limitations
- Repeatability (±0.05 mm on larger models) is not competitive with industrial SCARAs or delta robots for precision tasks
- Cycle speed is slower than dedicated industrial robots — UR10e typical machine-tending cycle 8–12 s vs 4–6 s for a fixed-guard industrial arm
- No native vision integration — requires URCap add-on; FANUC CRX has iRVision built in
- PolyScope lacks simulation or offline programming tools out of the box — URSim available but limited
- Not ideal for very high-duty-cycle applications (20+ hours/day at rated payload) — designed for collaborative duty cycles

Frequently Asked Questions
What is the difference between UR10e and UR10?
The UR10e (e-Series, launched 2018) added built-in force/torque sensing at all six joints, a new teach pendant interface (PolyScope X), improved safety certification (PL d, Cat. 3), and a slightly updated mechanical design. The original UR10 (CB3 series) is no longer in production but is widely available second-hand. Software-wise, URScript programs are not directly compatible between CB3 and e-Series without modification. If you are buying new, buy e-Series; if buying used, verify the controller generation before purchasing accessories.
Can a UR cobot work without a safety cage?
Potentially, but only after a documented risk assessment per ISO 10218-2 and ISO/TS 15066. "Collaborative" does not mean "automatically safe without guarding." The risk assessment must identify all hazards (including pinch points, tool tip hazards, and part ejection), and the power-and-force-limiting safety function must be configured to stop the robot before injury thresholds are exceeded. In practice, many UR deployments do include guarding — either because the application is not fully collaborative (speeds are too high) or because the parts or tooling create hazards the PFL function cannot mitigate.
How long does programming a UR take?
A simple pick-and-place with a Robotiq gripper URCap: 30–120 minutes for an operator with one day of training. A complex machine-tending cell with conditional logic, error recovery, and part type detection: 2–5 days for an experienced integrator. The PolyScope interface genuinely makes basic programming accessible — but complex programs with branching logic, vision-guided pick, or multi-step processes still require expertise. UR provides free online training (UR Academy) covering basic through advanced programming.
What is the UR's payload limit including the gripper weight?
Payload refers to the total mass at the tool flange — gripper weight plus part weight. A UR10e rated at 10 kg with a 1.8 kg Robotiq 2F-85 gripper has 8.2 kg available for the part. Always calculate effective part payload = rated payload − gripper weight − any cable management hardware. At extended reach, effective payload is further reduced by the robot's own dynamic limits — UR publishes payload-vs-reach curves in the technical datasheet.
