Kinematics: DH parameters

DH and inverse kinematics explained

Standard Denavit–Hartenberg parameters as published by Universal Robots. θ is the joint variable, so no fixed θ offset is listed. Universal Robots notes that its “a” corresponds to the “r” parameter in some DH references. [2]

Universal Robots publishes this table as “UR30”.
These are nominal design values. A specific arm's calibrated kinematics can differ; check your controller's calibration data before relying on nominal values for absolute positioning.

Where it sits in the range

UR30 lists 30 kg, or 35 kg under boundary conditions in the manual, on the same Ø245 mm footprint and EN ISO 9409-1-80-6-M8 flange as UR20. It trades reach and speed for payload: 1,300 mm and 4 m/s against UR20's 1,750 mm and 5 m/s.

Both arms list ±0.1 mm repeatability, the widest tolerance among the Universal Robots arms in this index.

What the datasheet cannot answer

A 30 kg rating is a ceiling under the manufacturer's conditions; the tool's centre of gravity and the risk assessment decide the usable load and speed. RoboMag has not physically tested UR30.
