- Rank
- Where you stand. RoboIndex is RoboScore + Momentum — the 0–100 evidence figure plus up to 15 points for a maker in the news. Both parts are printed on every row, so you can check the sum.
- Momentum
- What's happening now. Up to 15 points, from news events that decay over 90 days. It can lift a rank, never sink one — a quiet maker keeps its RoboScore in full. Recomputed daily, so positions can move between weekly score freezes.

How we rank
RoboIndex ranks each robot by RoboScore — a 0–100 evidence score — plus up to 15 Momentum points for a maker with live news. Momentum can only add to a rank, never subtract from one.
Which robot ranks #1 for Actuator?
LASF Series (Unknown) ranks #1 for Actuator as of 4 Oct 2026, by RoboIndex.
How many actuator robots does Robolist.ai rank?
Robolist.ai ranks 22 actuator robots as of 4 Oct 2026.
How is RoboIndex calculated?
RoboIndex is RoboScore — a 0-100 evidence score from structured data — plus up to 15 Momentum points from dated news, which decay over about 90 days. Momentum can only add to the score, never subtract from it. Full breakdown at /methodology.
How often is the Actuator standing updated?
Scores freeze once a week; the board shows that weekly standing. This standing is current as of 4 Oct 2026.
The Score Δ column only moves when a robot's own score moved. It is not a report on the week: rank position drifts whenever a neighbour moves, and publishing that as an arrow would be inventing movement. A robot that did not change reports how long it has sat where it sits, in days and then in weeks — so a score that settled last week is told apart from one nothing has touched in months. A trailing + means that streak runs back to the 30 July rescoring and is a floor, because no score can be compared across a change of formula.
Robots first sold before 2020 are held out of the standing. Robots with no recorded launch year stay in — an unknown year is not evidence of age, and treating missing data as old would quietly delete most of the catalogue.
Momentum belongs to the maker, not the robot. Every robot a maker sells moves together. Where we have no news signal at all the row says so in words rather than showing a zero — a zero would claim the company is quiet, when all we actually know is that we have not heard anything.
Makers are ranked on a separate board. A robot is never ranked against a company, so Top Actuator Companies is its own standing, built from each maker's robots in this category alone.
How this ranking is built — the factors behind the score, the year gate, how ties are ordered, and why Momentum is capped and bonus-only rather than averaged into the score.
