Robotic giant Siasun releases China’s first cobot with 25 kg payload — company

In addition to hardware upgrades, the new GCR25-1800 device also received revamps to the software, and has become more intelligent.

Siasun (中科新松, 300024.SH), a leading robot producer affiliated with Siasun Group, has recently announced a new cobot product with a payload of 25 kg, the first of its kind in China, the company claimed.

The robot, called GCR25-1800 and belonging to Siasun’s Duco series, has a unit weight of 61 kg, almost 10% lighter than similar Duco variants with a maximum payload of 20 kg.

Traditionally, Chinese-made cobots’ payload reaches up to 20 kg. A lighter weight means the robot has better agility, fit for production line overhauls.

“GCR25-1800 has filled the market void of cobots with a payload of 25 kg,” said Siasun. “It can satisfy more varied needs of clients.”

Besides a higher payload, GCR25-1800 possesses an arm’s length of 1,800 mm, suited to heavy material handling and palletizing.

The design also provides safety guarantees in an all-around manner and realizes human-machine collaboration, Siasun claims in a product brochure.

The robot promises higher efficiency, thanks to a 20% increase in the robotic arm’s pace of movement compared to products featuring a payload of up to 20 kg.

With a position repeatability of only ± 0.05 mm, the robot can significantly improve the efficiency of smart manufacturing, said Siasun.

It also comes with a more compact controller box. At 410 x 306 x 292 mm, it is smaller than its cousins by 30% and lighter by 20%. This means the robot can operate in a tight space.

In addition to hardware upgrades, the new GCR25-1800 device also received revamps to the software, and has become more intelligent.

Its Duco Core operation system, capable of integrating vision control, elevates human-machine collaboration and delivers a better user experience, Siasun stated.

GCR25-1800 is a new member in Siasun’s Duco family of robots, which have been adopted at scale in automobile, semiconductor, 3C, new retail, photovoltaic and textile industries.

The series now boasts dozens of robotic products, covering cobot, autonomous mobile robot (AMR), and components like controller, stocker and overhead shuttle, an automated overhead transport system.
