Robot brand choice is a 15-year decision
A robot bought in 2026 will likely still be in production in 2041. The brand decision determines the maintenance team you need, the spare-parts logistics, the IDE your team writes programs in, the cobot story when the customer wants one — and, two upgrades later, the migration cost when the controller goes end-of-support.We work with all four of these regularly. None of them is universally the right answer. Here's how we pick.
ABB
Strengths: RobotStudio is, in our opinion, the best offline programming environment of the four. The IRC5 / OmniCore controllers are reliable. SafeMove is well-integrated. Strong installed base in EU automotive and process industries.Trade-offs: cobot story is improving (GoFa, SWIFTI) but lagging UR. Cycle time on the smaller industrial arms isn't always class-leading.
Default for: greenfield European projects, customers with existing ABB knowledge, anywhere offline programming + simulation is critical.
KUKA
Strengths: high payload range, excellent in heavy automotive (body shop, paint), KUKA Sunrise / KRC4 controllers are mature. The KR Cybertech series is workhorse-class. KUKA.SystemSoftware is robust.Trade-offs: KRL (the programming language) is its own universe — engineers from FANUC or ABB take time to ramp. Tooling is improving but historically less open than ABB.
Default for: heavy-payload work, German automotive supply chain, customers with KUKA-trained maintenance.
FANUC
Strengths: reliability is genuinely class-leading in our experience. The yellow paint is on a lot of machines for a reason. Strong in machine tending, packaging, and Japanese / Asian supply chains. The R-30iB controllers run forever.Trade-offs: programming environment (TP / Karel) is functional but feels dated next to RobotStudio. Vendor lock-in for spare parts is meaningful.
Default for: high-volume, lights-out production where uptime over years matters more than developer ergonomics.
Universal Robots (UR)
Strengths: the cobot incumbent. PolyScope is operator-programmable, the URCap ecosystem is rich, and the integration story for end-effectors / vision is the most mature of the cobot category.Trade-offs: reach and payload ceilings (UR20 helps but doesn't close the gap to industrial arms). Speed is cobot-class — collaborative limits cap cycle time.
Default for: human-adjacent stations, frequent product changes, customers who want operators to teach the robot themselves.
Things that decide brand more than features
- Existing fleet. If the plant is 90 % FANUC, you ship FANUC unless there's a strong technical reason. Operations teams don't enjoy multi-brand fleets.
- Local service network. A robot down for two weeks waiting on a controller swap costs more than the brand premium for a vendor with stronger local support.
- Programming language footprint. If your team has 1 000 lines of KRL, RAPID is a long-term cost. Standardise where you can.
- Safety integration. SafeMove (ABB), SafeOperation (KUKA), DCS (FANUC) — different philosophies, different validation effort.
- Cobot story. If the project might add a cobot in 2 years, vendors with both lines (ABB, FANUC) reduce future complexity.
The simulation question
Run an offline simulation before committing to mechanical layout. Reach-and-cycle-time misjudgments cost more than the entire simulation effort to prevent. We use:- RobotStudio for ABB
- KUKA.Sim for KUKA
- Roboguide for FANUC
- Visual Components / RoboDK for multi-vendor cells or comparative studies
One thing we'd never repeat
Promising a customer "we'll integrate the robot via a generic OPC UA wrapper" without prototyping it on the actual brand first. Robot ↔ PLC integration is brand-specific in ways that don't show up until you wire it. Always prototype the comms layer before quoting.What's your default? And is anyone seeing UR encroach on the smaller industrial arms in real cells?
