Who Actually Builds the World's Industrial Robots?

Four established builders, FANUC, ABB, Yaskawa and KUKA, still anchor the global market, but the decisive shift of the last decade happened in China. Domestic Chinese manufacturers held 57 % of their home market in 2024, against roughly 28 % as a decade average, and China alone absorbed 295,000 of the 542,000 robots installed worldwide that year.

How the supplier landscape is structured

It helps to think in three tiers, because they compete on different things.

The tiers are converging. Chinese builders have moved from low-payload handling into welding and higher payload classes, while established builders have pushed into collaborative arms, a segment they initially ceded.

The China story in numbers

China is not simply the largest market, it is a structurally different one. Of the 542,000 industrial robots installed worldwide in 2024, China took 295,000, which is 54 % of global demand in a single country. Its operational stock passed 2 million units. Robot density reached 166 per 10,000 manufacturing employees, a 17 % rise year on year, which puts China 22nd worldwide and 6th in Asia despite the enormous absolute volume.

The share shift matters more than the volume. Domestic suppliers taking 57 % of that market means Chinese builders shipped on the order of 168,000 robots into China alone in 2024, a figure that exceeds the entire European and American markets combined, which were 85,000 and 50,100 units.

Who makes the parts

Robot builders are assemblers to a greater degree than most buyers realise, and the component layer is more concentrated than the robot layer.

• Precision gearboxes. Cycloidal and harmonic reducers come from a very small number of specialists, historically dominated by Japanese suppliers such as Nabtesco and Harmonic Drive. This is the tightest bottleneck in the whole chain.
• Servo motors and drives. A broader field, with Japanese, European and increasingly Chinese suppliers. Several robot builders make their own.
• Encoders. Concentrated among a handful of precision suppliers, since 17 to 23 bit absolute encoders are demanding parts.
• Controllers. Almost always proprietary to the robot builder, which is why the software ecosystems remain incompatible.
• End effectors and sensing. A large, fragmented and competitive market, which is where most innovation reaches the cell.

Vertical integration is the strategic story. FANUC and Yaskawa build motors and drives in-house; several Chinese builders have invested heavily in gearbox capacity precisely because the reducer bottleneck was the constraint on their growth.

What this means when you buy

1. Service coverage beats specification. A robot that stops on a Friday needs a spare and an engineer, not a better datasheet. Confirm response time and parts depot location before comparing repeatability figures.
2. Controller ecosystem locks you in. Programs, safety configuration and integration know-how do not transfer between builders. Standardising on one controller across a plant is worth real money in training and spares.
3. Lead time is a live variable. Delivery times have swung between 4 and 30 weeks across the last decade depending on component supply. Ask for a written date.
4. Regional support quality varies more than product quality. The same brand can be excellent in one country and thin in another, because distribution is often through partners.
