The maximum weight a robot can carry or manipulate at its end-effector while maintaining specified performance (speed, accuracy, repeatability).
How much weight can the robot lift and move around? This includes the tool attached to it plus whatever it's carrying. A robot rated for 10kg payload can handle a 3kg gripper plus a 7kg part.
Why It Matters
Payload is one of the first specs checked when selecting a robot. Underestimate it and the robot can't do the job. Overestimate it and you overpay for a bigger robot. In China's booming cobot market, the trend is toward higher payloads in compact form factors, enabling cobots to replace heavier industrial robots.
Real-World Examples
- A 3kg-payload cobot handling electronics assembly (typical for PCB work in Shenzhen)
- A 20kg-payload cobot for machine tending (loading/unloading CNC machines)
- A 300kg-payload industrial robot for palletizing heavy boxes in a warehouse
Chinese cobot makers have aggressively expanded payload ranges. JAKA offers cobots from 1kg to 18kg, Elite Robots goes up to 30kg, and Flexiv's Rizon handles up to 16kg with force sensing. This high-payload cobot trend is driven by China's manufacturing sector, where cobots increasingly replace traditional industrial robots.
