Kawasaki Robotics is the industrial-robotics business of Kawasaki Heavy Industries, Ltd., the Japanese heavy-engineering and transportation conglomerate. Formally the company's Robot Business Division and headquartered at the Akashi Works in Hyogo Prefecture (with adjacent operations at the Nishi-Kobe Works), it is one of the oldest robot makers in the world. In 1969 Kawasaki built the Kawasaki-Unimate 2000, Japan's first domestically produced industrial robot, under a technology license from the American pioneer Unimation. More than five decades later the division supplies welding, painting, palletizing, semiconductor-wafer, and medical robots to industry worldwide, with an installed base the company puts at over 200,000 units. Since 2015 Kawasaki has also run a long-horizon research program in legged and humanoid robots, the best known product of which is the Kaleido humanoid, whose ninth generation, Kaleido 9, was shown in December 2025.
Kawasaki Robotics should not be confused with Kawada Robotics, a separate Tokyo company that makes the Nextage industrial humanoid and co-developed the HRP humanoid series, nor with the Kawasaki motorcycle and recreational-vehicle business, which is a sibling unit inside the same Kawasaki Heavy Industries group rather than the robotics division.
The modern industrial robot was invented in the United States: the entrepreneur Joseph F. Engelberger founded Unimation, Inc., which built the Unimate, the world's first industrial robot. Kawasaki Heavy Industries signed a technology-license agreement with Unimation in 1968, sent engineers to the United States, and imported sample machines to its Akashi plant for study. In 1969 the first Kawasaki-Unimate 2000 rolled off the line, becoming the first industrial robot manufactured in Japan. The timing coincided with Japan's high-growth era and an emerging labor shortage, and the machine was taken up mainly by carmakers: in 1973 Toyota and Nissan adopted Kawasaki-Unimate robots for spot welding of auto bodies.
Kawasaki produced robots under the Unimation license for nearly two decades before moving to its own designs. The division's published timeline records the key milestones:
| Year | Milestone |
|---|---|
| 1968 | Signed technology-license agreement with Unimation (USA) |
| 1969 | Started production of Japan's first industrial robot (Kawasaki-Unimate) |
| 1981 | First electric robot, the P-series |
| 1983 | Large general-purpose E-series |
| 1986 | Terminated the Unimation license and began developing wholly in-house robots |
| 1992 | Large U-series and first all-digital controller (AD-series) |
| 1997 | Expanded its clean-room (semiconductor) robot business |
| 2000 | Acquired the painting-robot business from Kobe Steel |
| 2002 | K-series painting robot and extra-heavy-duty M-series |
| 2009 | Parallel-link picking robot (Y-series) |
| 2015 | MG10HL extra-large-payload robot and the duAro dual-arm collaborative robot |
| 2017 | RS007N/L high-speed robots and the Kaleido humanoid |
| 2018 | 50th anniversary of the robotics business; duAro2 |
The shift from license to original development in 1986 let Kawasaki broaden beyond automotive welding into clean-room handling, painting, palletizing, and, later, collaborative and service robots.
Kawasaki Robotics operates as the Robot Business Division inside Kawasaki Heavy Industries rather than as a standalone listed company. Engineering and manufacturing are centered on the Akashi Works and the neighboring Nishi-Kobe Works in Hyogo Prefecture, Japan. The division sells globally through regional subsidiaries, including Kawasaki Robotics (U.S.A.), Inc., and units in the United Kingdom, Germany, South Korea, China, Taiwan, Thailand, and India. The brand presents itself as a pioneer and long-standing leader in the field on the strength of its 1969 first.
Kawasaki's core business is articulated industrial robot arms and the controllers and software that drive them. The portfolio spans a wide payload and reach range and is organized largely by application.
Welding for the automotive industry has been Kawasaki's anchor application since the 1970s. The range covers spot welding (the BX-series spot-welding robots introduced in 2011), arc welding, and friction spot joining, used to assemble car and truck bodies. Welding remains one of the largest segments of the industrial-robot market, where Kawasaki competes with FANUC, Yaskawa, ABB, and KUKA.
High-payload palletizing and handling robots move finished goods and heavy parts. Kawasaki markets dedicated palletizing models capable of high cycle rates and large payloads (its heaviest handling robots carry several hundred kilograms), along with the extra-large MG-series for the heaviest loads.
Kawasaki has a long-established clean-room business serving semiconductor and electronics manufacturing. Its NT and NV series are high-speed silicon-wafer transfer robots built to SEMI standards (such as SEMI-S2), designed to access multiple FOUP load ports in an equipment front-end module (EFEM) and to move wafers smoothly inside cleanrooms.
Kawasaki entered medical and pharmaceutical automation in the 2010s. The MS005N is a 7-axis robot with an all-stainless-steel body that is resistant to vaporized hydrogen peroxide (VHP) decontamination and meets ISO Class 5 (US FED STD 209E Class 100) cleanroom requirements, aimed at aseptic dispensing, inspection, assembly, and handling of high-potency drugs such as anticancer agents.
Launched in 2015, duAro is a dual-arm SCARA collaborative robot (cobot) that packs two coaxial arms plus a controller into the footprint of a single human worker, so it can be installed alongside people on a production line. Safety features include low-power motors, speed limiting, area monitoring, and collision detection that halts the arms on contact. A second model, duAro2, with a wider working envelope, was added in 2019. The duAro line marked Kawasaki's move into human-coexisting automation for tasks like light assembly, machine tending, and food handling.
Unveiled at the International Robot Exhibition (iREX) in November 2017, Successor is a remote-cooperation and skill-transfer system meant to bring robots into jobs that are hard to automate by conventional programming. An expert operator manipulates a robot in real time through a force-feedback device Kawasaki calls the Communicator, transferring not just motions but the feel of a task, such as the force in the fingers or subtle wrist movements. The robot records these movements and can then reproduce them automatically. Because the link is remote, one worker can supervise several robots from an office and switch between manual control and autonomous replay, an approach related to broader ideas in robot teleoperation. Kawasaki framed Successor around aging-workforce and skills-succession problems in Japanese manufacturing.
Alongside the factory business, Kawasaki has run a research program in legged robots since 2015 under the banner of the Robust Humanoid Platform (RHP). The program has produced the bipedal Kaleido humanoid and several "friend" derivatives, including the quadruped Bex and the slim RHP Friends, as well as the later Corleo rideable concept.
Kawasaki began humanoid research in 2015 and showed the first-generation Kaleido at iREX 2017. Early Kaleido units were large, industrial-grade bipeds: widely reported figures put the early robot at about 178 cm tall and 85 kg with roughly 32 degrees of freedom, with industrial-strength actuators able to handle loads in the tens of kilograms. The name reflects the goal of a robot that can support people in difficult, unpredictable settings such as disaster sites, since a remotely operated humanoid could enter hazardous areas while its operator stays safe elsewhere. Stated target uses include disaster response, heavy physical labor, and assistance in healthcare and nursing.
Kawasaki has iterated the platform roughly annually, numbering versions as RHP generations. The seventh-generation Kaleido, shown at iREX 2022, stood about 180 cm and 80 kg and walked at roughly 4 km/h (about human walking speed) with a more natural, straighter-kneed gait than earlier prototypes, which had to keep their knees bent. Over successive versions the team added an onboard battery for untethered operation, a lighter magnesium-alloy frame, custom force/torque sensors, and improved real-time balance.
The ninth generation, Kaleido 9, was unveiled at iREX 2025 in Tokyo in December 2025. Kawasaki positions it as a robust, practically minded platform rather than an acrobatic showpiece. Reported specifications and capabilities include:
| Attribute | Kaleido 9 |
|---|---|
| Generation | 9th (Robust Humanoid Platform) |
| Height | about 190 cm |
| Weight | about 99 kg |
| Lift capacity | about 18 kg (reported as roughly a 35% increase over the previous generation) |
| Sensing | LiDAR plus stereo cameras; SLAM-based self-localization for autonomous walking |
| Control | autonomous operation, or remote teleoperation by a human pilot via a head-mounted display |
| Status (June 2026) | still in testing, not commercially available |
Kawasaki says Kaleido 9 has been in development for close to ten years. In its iREX 2025 demonstrations the robot swept a yard with a broom, took out trash, removed a shelf, and operated a hose in a simulated, teleoperated firefighting scenario. The company has outlined a long roadmap for the platform: around 2030 it targets simple factory and plant tasks plus communication support in medical and nursing-care settings; around 2040, mechanical assembly and high-altitude work; and around 2050, deployment in the most challenging environments, including disaster response, with environmental hardening such as waterproofing. A companion concept, the Kaleido Station, is a wheeled platform that would carry the humanoid over longer distances and serve as a charging dock.
Bex (styled RHP Bex) is a four-legged robot Kawasaki revealed at iREX 2022, named after and styled like the ibex, a horned wild goat. Bex grew directly out of the Kaleido work: Kawasaki engineers said that developing the biped taught them how hard two-legged locomotion is and that legs still suit rough terrain better than wheels. Bex uses a hybrid mobility system, walking on four legs over uneven ground but able to kneel onto wheels mounted at its knees to roll quickly across smooth, flat surfaces. The lower body is meant as an open-innovation transport platform that can carry on the order of 100 kg of cargo, with a modular upper body adapted per customer for jobs such as hauling materials on construction sites, inspecting industrial plants by remote camera, or carrying crops on farms. Kawasaki also gave one unit a seat and handlebars, producing a rideable robotic "goat" demonstration that drew wide attention online, though that was a showcase rather than a product.
RHP Friends is a slimmer, lighter, human-coexisting humanoid Kawasaki presented at iREX 2022 as a Kaleido derivative aimed at working safely around people in everyday environments and at care tasks. In its iREX 2022 demonstration Friends performed gentle motion-captured movements and pushed a mannequin in a wheelchair across the stage. It reflects the program's branch toward service and caregiving alongside the heavier, industrial Kaleido line.
In April 2025 Kawasaki unveiled Corleo, a hydrogen-powered, four-legged rideable concept vehicle, at the Osaka-Kansai Expo 2025, where a prototype was displayed at the company's pavilion. Corleo is a two-seater quadruped that the rider steers largely with body movement, with an AI vision system that reads the terrain ahead and chooses footholds; each leg ends in a split rubber hoof for grip on grass, gravel, and rock. Rather than a fuel cell, it carries a 150cc hydrogen generator engine that charges a battery to drive the legs, emitting water vapor. Kawasaki presented Corleo as a vision of off-road personal mobility for around the 2050s. Coverage noted that the dramatic promotional footage of Corleo galloping and leaping is computer graphics, while the physical prototype can stand and shift its posture but has limited real mobility.
Because both are Japanese makers of humanoid-capable robots with similar names, Kawasaki Robotics and Kawada Robotics are sometimes confused. They are unrelated companies. Kawada Robotics is a subsidiary of Kawada Technologies (a Tokyo construction and engineering group) and is known for the Nextage dual-arm industrial humanoid (introduced in 2011) and for the HRP full-body humanoid series developed out of Japan's national Humanoid Robotics Project (1998-2002). Kawasaki Heavy Industries was one of several industrial supporters of that national project, but the Kaleido program and Kawasaki's commercial robot business are entirely separate from Kawada's products.
Kawasaki is consistently counted among the major global industrial-robot manufacturers, a group led by FANUC, Yaskawa, ABB, and KUKA. Its strongest historical position is in automotive welding, and it remains a significant supplier in welding, palletizing, semiconductor handling, and pharmaceutical automation. The humanoid program has drawn outsized media attention, especially the rideable Bex and Corleo demonstrations and the Kaleido 9 reveal, even though, as Kawasaki itself states, Kaleido remains a research platform in testing rather than a shipping product as of mid-2026. Commentators have generally read Kawasaki's approach, emphasizing robustness, remote operation, and real-world utility over athletic feats, as a contrast to the more acrobatic humanoid demonstrations from companies such as Boston Dynamics and to Honda's earlier ASIMO.
