Industrial Robot Brands: 15-OEM Buyer Directory

How To Read This Industrial Robot Brand Directory

Industrial robot brands are not interchangeable. The International Federation of Robotics reports that four suppliers — FANUC, ABB, KUKA, and Yaskawa — historically account for the largest share of global industrial robot installations, with Chinese OEMs such as Estun, Efort, and Siasun growing quickly at home.

Every arm in the table below is a real, currently sold product with a public datasheet from the manufacturer. The Bot Scout has not listed a price where the OEM does not publish one. Industrial arms are almost always sold through integrators, and list prices, when they exist at all, appear on distributor sites such as RobotWorx or Eurobots rather than the OEM.

Read the directory as a shortlist tool, not a ranking of quality. The right brand for a plant depends on the payload, reach, environment (weld, paint, clean, food), the integrator network in your region, and whose controller your team already knows.

The Big Four Global OEMs (FANUC, ABB, KUKA, Yaskawa)

FANUC, ABB, KUKA, and Yaskawa Motoman are the four industrial robot manufacturers every plant benchmarks first. FANUC alone reports having shipped more than one million robots worldwide, and its yellow arms dominate automotive machine tending. ABB is strongest in painting, arc welding, and pick-and-place with the FlexPicker parallel arm. KUKA — now owned by China's Midea Group — leads in heavy-payload spot welding for automotive body shops. Yaskawa Motoman covers a broad range with strong arc-welding and handling lines.

None of the four publish list prices for their industrial arms. New six-axis systems typically clear the OEM as bare-arm quotes from six figures downward, with the integrated cell (end effector, safety, controls, install) usually landing well above the arm itself. Distributor listings for used equipment give a directional floor, not a plant price.

For a like-for-like specification comparison, cross-check the arm datasheets on RobotWorx, and confirm payload and reach on the OEM datasheet before requesting a formal quote.

Japanese Specialists (Kawasaki, Nachi, Denso, Epson)

Beyond Yaskawa and FANUC, four other Japanese manufacturers ship substantial volume. Kawasaki Robotics was Japan's first industrial robot maker (licensing Unimation in 1969) and remains strong in spot welding and heavy handling. Nachi Robotics supplies spot-welding arms into Toyota and other automakers, plus the smaller MZ series. Denso Robotics is the spinout of Toyota's supplier Denso Corporation and specialises in compact 4- and 6-axis arms under 20 kg payload for electronics and medical. Epson is one of the few OEMs that publishes MSRP for its SCARA and 6-axis arms, which makes budgeting straightforward.

For small-payload, high-speed applications — electronics assembly, lab automation, packaging — Denso and Epson often out-spec the Big Four on cycle time in the sub-10 kg class.

• Kawasaki BX200L — 200 kg payload, 2597 mm reach; automotive spot weld.
• Nachi MZ07 — 7 kg payload, 723 mm reach; compact assembly.
• Denso VS-060 — 7 kg payload, 810 mm reach; electronics and pharma.
• Epson C4 — 4 kg payload, 600 mm reach; MSRP published, distributor stock.

European Specialists (Stäubli, Comau)

Stäubli is the specialist choice for cleanroom, pharmaceutical, and food applications. The TX2 series is engineered for ISO Class 5 cleanrooms and hygienic environments in stainless-steel variants, which the Big Four generally do not offer as a stock configuration. Comau, part of Fiat/Stellantis heritage, is strong in body-in-white welding cells and offers the Racer-5 cobot on the light end.

Both brands quote through integrators. Stäubli specifically is often shortlisted after the Big Four have been ruled out for regulatory reasons (pharma, aseptic fill, semiconductor wet process).

Korean and Chinese Industrial Robot Manufacturers

Hyundai Robotics spun out of Hyundai Heavy Industries and supplies spot-weld and handling arms to Hyundai/Kia plants worldwide, with a growing export presence. In China, the top domestic OEMs by installed base are Estun, Efort, and Siasun, with GSK a lower-cost alternative. Estun is publicly listed on the Shenzhen exchange and acquired Germany's Cloos welding-robot business in 2019, giving it a full welding portfolio.

Chinese OEMs typically undercut Japanese and European list prices, sometimes by 30-50% at parity payload, but international buyers should verify integrator support, spare-parts lead time, and controller documentation in English before committing. IFR data cited by World Robotics 2024 shows China remains the largest single market for industrial robot installations, and domestic brands now win most of the local unit share.

• Estun ER20 — 20 kg payload, 1700 mm reach; general handling.
• Efort ER50 — 50 kg payload, 2100 mm reach; palletizing.
• Siasun SR6C — 6 kg payload, 1400 mm reach; assembly.
• GSK RB08 — 8 kg payload, 1400 mm reach; low-cost handling.
• Hyundai HH050 — 50 kg payload, 2100 mm reach; automotive handling.

Collaborative Arms Sold Alongside Industrial Ranges

Several industrial OEMs also sell collaborative arms that are technically industrial robots under ISO 10218-1:2025. Universal Robots (owned by Teradyne) leads the cobot market with the UR3e/UR5e/UR10e/UR16e/UR20/UR30 line. Techman Robot (Quanta subsidiary) integrates vision into every arm. Doosan Robotics covers 5-25 kg payload cobots and IPO'd on the Korea Exchange in 2023.

Universal Robots is one of the very few industrial-class OEMs that publishes indicative pricing through its distributor network — a UR5e typically lists in the low tens of thousands of USD as a bare arm, though the plant-installed cell is materially more. Cobots suit shorter cycle, lower payload, and human-adjacent work; they do not replace a fenced high-speed six-axis for automotive body-in-white.
