Universal Robots UR20
The Universal Robots UR20 is a next-generation 6-axis collaborative robot (cobot) featuring a 20-25kg payload capacity, 1750mm reach and ±0.1mm pose repeatability.
The UR20 has been redesigned from the ground up to provide up to 30% higher speed and torque, advanced motion control capabilities and first-class user experience.
Applications include heavy-duty automation tasks such as machine tending, material handling, welding, packaging and palletizing.

Cartesian Parameters
- Maximum TCP linear speed: 5000mm/s
- Recommended maximum TCP linear acceleration: 2500mm/s²
- Recommended maximum TCP angular speed: 210°/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.
