Collaborative arms ranked by repeatability

Repeatability describes how closely a robot arm returns to the same point across repeated moves. The 25 ranked robots here come from three makers — Dobot, Doosan Robotics, and Universal Robots — and their published figures span from 0.02 mm to 0.1 mm.

Ranked by repeatability

What the table shows

• Two robots share rank 1 at 0.02 mm — the CR5AS and the M1 Pro, both from Dobot — while the last-placed UR30 from Universal Robots is published at 0.1 mm.
• Seven robots share rank 3 at 0.03 mm, and the published payload figures within that group run from 3 kg to 15 kg.
• The median across ranked robots is 0.05 mm, a figure shared by 11 robots that all carry rank 10 in the table.
• 41 of the 66 collaborative arms in the database do not publish a repeatability figure.

How this was made

Every figure is the maker's own published specification, as held in our database on 2026-10-06, converted to one unit; the source column links the document it comes from. 41 other robots in our collaborative arm category publish no repeatability figure and are not ranked. The words around the table were written by our writer agent from these figures alone, and checked by a person before publication.
