What Kawasaki Robotics Builds
Kawasaki Robotics is the industrial robot arm business of Kawasaki Heavy Industries, and it has been running since 1968. In the guides we publish here we cover both halves of this company, because two very different questions land on the same name.
One is about a BX-series welding arm, a controller error code, or a battery replacement. The other is about a video of a robot goat, and whether one company makes both.
It does. The arms and the legged machines come out of the same company, and the connection between them is more than branding.
Kawasaki signed a licence agreement with Unimation in 1968 and started producing the Unimate in 1969, which was the first industrial robot manufactured in Japan. Kawasaki's own division history records the licence ending in 1986, after which it designed its own robots.
| Series | Job | Where you meet it |
|---|---|---|
| R, U, Z series | General-purpose handling and palletising | Factory floors, warehouse lines |
| BX series | Spot welding and heavy handling | Automotive body shops |
| K series | Painting and coating | Paint booths, from the Kobe Steel business acquired in 2000 |
| NT series | Clean-room handling | Semiconductor and display fabs |
| duAro2 | Dual-arm collaborative work | Cells shared with people |
| Kaleido and BEX | Humanoid and legged research | Exhibitions and disaster-response research |
Where Kawasaki Sits Among Industrial Robot Makers
Kawasaki is a major robot manufacturer and it is not one of the big four. That group is FANUC, ABB, KUKA, and Yaskawa, and we cover how they split the market in our guide to the big four robot OEMs.
Sitting one tier down changes what a buyer should expect, in both directions. A smaller installed base means fewer integrators and a thinner third-party parts market, which shows up as longer waits for a specialist. Confirm coverage through the regional Kawasaki office rather than assuming it.
What it has instead is depth in specific jobs. Automotive body welding and paint are Kawasaki strongholds, and its own division history dates the paint line to the acquisition of Kobe Steel's painting robot business in 2000.
Semiconductor handling is the other strength. The NT clean robots serve fabs, which is a market where the qualification cost is so high that customers rarely switch supplier once a line is running.
The practical read for a buyer is to check integrator coverage in your own region before shortlisting. A capable arm with no local integrator is a slower project than a mid-range arm with three.
The Kawasaki Robot Goat and Robot Horse
The legged machines come from Kawasaki's Kaleido humanoid programme, which has run since 2015 and reached its seventh generation by 2021. Kaleido was shown publicly at the International Robot Exhibition in 2017 and walked untethered on battery power by 2019.
BEX is the machine most people mean by the Kawasaki robot goat. It is a rideable quadruped modelled on an ibex, shown at the same exhibition in 2022. It carries roughly 100 kg and switches between four legs and wheels mounted at its feet and knees.
CORLEO is the robot horse, and it is a concept rather than a product. Kawasaki showed a full-scale model at the Osaka-Kansai Expo preview in April 2025, and the widely shared footage of it running is computer animation.
There is no Kawasaki robot dog for sale. The legged machines are research and exhibition platforms, and Kawasaki has published no price or order route for any of them.
The full timeline, including the 2035 commercialisation target, is in our Kawasaki CORLEO explainer, and the machines a person can ride are compared in our rideable robots guide.
Successor and the Remote Operation Angle
Successor is the part of Kawasaki's lineup that most competitors have no equivalent for. Kawasaki's division history dates it to 2017, alongside the Kaleido humanoid. It describes Successor as a remote cooperation system that lets a person operate a robot at a distance and teach it while doing so.
Successor removes the programmer from the cell. Conventional robot teaching needs one on site. Successor instead lets a skilled operator run the motion by hand and have the robot learn it, cutting the specialist hours a new part number costs.
That matters most where the work changes often. A line running one part for three years does not need it, and a shop running short runs pays for reprogramming constantly.
It also connects the two halves of the company. A humanoid or a legged machine sent somewhere a person should not go still needs a human deciding what it does, and remote operation is that link.
Owning a Kawasaki Arm
Most Kawasaki searches come from people who already own one, and the questions repeat. Controller error codes, encoder battery replacement, brake release, and integration files are the four that turn up constantly.
The pattern behind the battery question is worth knowing before it bites. A robot arm keeps its joint positions in an encoder backed by a battery. Let that battery die and the arm loses its zero position, which means remastering by someone who knows the procedure.
Treat that as scheduled maintenance rather than as a repair. Replacing encoder batteries on a calendar, with the controller powered, avoids the remastering entirely, and it is the cheapest thing a maintenance team can do for an ageing cell.
Error codes and integration files come from Kawasaki rather than from a forum. Codes are controller-generation specific. A code list for an older controller can describe a different fault on a newer one, so pull them from Kawasaki Robotics support for your exact controller.
Sitting a tier below the big four has a daily consequence here. Kawasaki has a smaller installed base than FANUC in North America, so fewer independent specialists have worked on one. The in-house team ends up doing more, and documentation access matters more than it would on a more common brand.
Who Should Buy a Kawasaki Arm
Kawasaki suits automotive body shops, paint lines, and clean-room fabs, particularly where a plant already runs Kawasaki controllers and the maintenance team knows them. Adding a second brand to an existing fleet costs more than the arm, in training and spares.
It is a weaker pick for a first robot in a small shop. A single-arm buyer with no in-house robotics staff will usually get further with whichever brand has the strongest local integrator. Our industrial robot brand comparison covers how to judge that.
Anyone shopping for a robot dog should look elsewhere entirely. Kawasaki does not sell one, and buyers who want a legged machine now are choosing between Chinese and American quadruped vendors instead.
Distribution would change that verdict faster than technology. If Kawasaki widens its integrator network in North America and Europe, the main reason to prefer a big-four brand for a small deployment goes away.
The other thing worth watching is whether the legged work reaches a product. Kawasaki Robotics has run legged research for a decade without selling one, and a priced, supported machine would put it in a market no big-four maker currently serves.
Bottom Line
Kawasaki Robotics is the company that built Japan's first industrial robot and is now the only major arm maker with a rideable quadruped in its labs. Before shortlisting a Kawasaki arm, ask the regional Kawasaki office which integrators near you have commissioned one in the last year. That answer decides your project timeline more than the specification does.

FAQs
Is Kawasaki one of the big four robot manufacturers?
No. The big four are FANUC, ABB, KUKA, and Yaskawa. Kawasaki is a major manufacturer a tier below them, with particular depth in automotive welding, painting, and semiconductor clean-room handling.
Did Kawasaki build the first industrial robot in Japan?
Yes. Kawasaki signed a licence agreement with Unimation in 1968 and began producing the Unimate in 1969, the first industrial robot manufactured in Japan. It ended the licence in 1986 and has developed its own robots since.
Can you buy a Kawasaki robot dog?
No. Kawasaki's legged machines, including the BEX rideable quadruped and the Kaleido humanoid, are research and exhibition platforms. Kawasaki has published no price and no order route for any of them.
What is the Kawasaki duAro?
duAro is Kawasaki's dual-arm collaborative robot. Kawasaki's division history dates the launch to 2015, and duAro2 followed with a longer vertical stroke and higher payload. It is a SCARA-type coaxial dual-arm unit designed to work in a space shared with people.
What is Kawasaki Successor?
Successor is Kawasaki's remote cooperation system, introduced in 2017. An operator runs the robot remotely and the robot learns the motion as it is performed, which reduces the specialist programming time each new part number costs.
Does Kawasaki make medical robots?
Yes, through Medicaroid, which Kawasaki's division history records it establishing in 2013 for medical robotics. It is a separate entity from the industrial robot division rather than a product line inside it.
