Universal Robots UR3e
The Universal Robots UR3e is a 6-axis collaborative robot (cobot) featuring a 3kg payload capacity, 500mm reach and ±0.03mm pose repeatability.
The UR3e is the lightest, most compact, and most precise robot in the Universal Robots lineup. The ±360° rotation limits on every wrist joint suit screw driving, finishing, and assembly work requiring tight tolerances.

Cartesian Parameters
- Maximum TCP linear speed: 3000mm/s
- Recommended maximum TCP linear acceleration: 2500mm/s²
- Recommended maximum TCP angular speed: 180°/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.
