Universal Robots UR18
The Universal Robots UR18 is a compact, heavy-duty 6-axis collaborative robot (cobot) featuring a 18kg payload capacity, 950mm reach and ±0.05mm pose repeatability.
The UR18 combines strength and agility, supporting larger end effectors to lift heavier payloads while remaining light enough for easy mounting on most standard gantry systems.
Applications include fast-paced pick-and-place, assembly, and material handling in industries such as logistics, automotive and foodservice, where reducing cycle times is crucial.

Cartesian Parameters
- Maximum TCP linear speed: 4000mm/s
- Recommended maximum TCP linear acceleration: 2500mm/s²
- Recommended maximum TCP angular speed: 300°/s
- Recommended maximum TCP angular acceleration: 800°/s²
Notes
- The 800°/s² joint acceleration and 2500mm/s² linear acceleration values are Universal Robots' recommended programming ceilings, not fixed physical actuator limits.
- Achievable acceleration depends on the robot pose, payload, payload centre of gravity, TCP forces and trajectory.
