JAKA is showing a heavy wheeled humanoid and a heavy cobot in Shanghai

JAKA told Shanghai Securities News, in a report published on 11 October, that it would globally debut two machines on 12 October at the 26th China International Industry Fair in Shanghai. One is the JAKA Kargo50, a heavy-load wheeled humanoid aimed at moving totes. The other is the JAKA Zu50, a heavy-payload collaborative arm. The company said the pair fills gaps it already has a lighter answer for: Kargo50 sits in an existing wheeled-humanoid series, and Zu50 completes a cobot range that ran from light loads through medium ones.

The report does not give the Kargo50’s payload in kilograms, its price, or a customer. “Heavy” is the company’s adjective. The model name is not a specification this desk will treat as a weighed figure. What JAKA did quantify is the previous machine. It said the Kargo10 is already in volume use at auto-parts and electronics factories. After time on those lines, the company says, the work of one tote fell from 105 seconds to 28 seconds, and a new site can be stood up in 57 days. Those are the seller’s before-and-after numbers. They are also the only operating figures attached to this launch, and they belong to the lighter robot.

A fair is not a shift

JAKA said it would bring real factory jobs into the hall rather than a single repeated gesture. That is a better demonstration than a wave. It is still a demonstration. A cycle time of 28 seconds on a Kargo10 that has lived on a line is evidence about that line. A debut of a heavier sibling, on the first day of a fair, is a product on a stand. The distance between the two is the whole argument of the last few weeks of this file: manufacturing only counts once the machine is repeated, and a repeated machine is the one that already has a stopwatch on it.

The company also cited a 2024 industry figure: a 21.9 percent share of China’s collaborative-robot market, which it says was first place. That is a year old, and it is about arms, not about wheeled humanoids. It explains why a cobot maker wants a heavy arm. It does not say the Kargo50 has a share of anything.

Wheeled humanoids are the unfashionable version of the category, and they are the version a factory can use first. The robot does not have to walk. It has to roll to a rack, lift a box, and come back. If Kargo50 does that at a load the Kargo10 cannot, it is a bigger tool in a series that already has a stopwatch. If it only does it in Shanghai this week, it is a heavier prototype.
