Autonomy Intelligence Profile
Robot Autonomy Index methodology →The Fourier GR-3 scores 78/100 on the Robot Autonomy Index (RAI), RobotSniper's 0–100 measure of how little human help a robot needs across navigation, obstacle avoidance, automation, and self-maintenance. That puts it in the Capable tier — solid semi-autonomous performance. Maps and cleans well but needs regular hands-on maintenance — emptying, rinsing, or rescuing.

Capable
This model carries a composite RAI of 78. The four-pillar sub-score breakdown — navigation, obstacle avoidance, automation, and maintenance independence — applies to our mobile home-cleaning robots (vacuums, mowers, pool and window bots); for other categories the composite is the headline score.
