Robot Autonomy Library16 definitions · reviewed Sep 28, 2026
Plain definitions for the words robot makers use, and for the ones Robovations uses to classify their machines. Every count on these pages is drawn live from the database.
The five levels of the Autonomy Ladder™, the parts of the Robovations Score, and the claims printed on the box. Each entry opens with one sentence you can quote, and every number on it comes from 605 classified robots.
Five levels. Each robot holds one, set by the behavior it is documented to perform.
The robot performs one repetitive motion when you tell it to, and you do nearly everything else.
The robot can start a task on its own, but needs frequent help to finish it.
The robot works on its own inside familiar conditions but struggles with the unexpected.
The robot copes with whatever turns up in its own space, seeing obstacles before contact, running without the space cleared first, and freeing itself when stuck.
A robot that handles any task, in any environment, without human guidance. No consumer robot has been classified there.
Three pillars at their true weight, each input drawn inside its own pillar. Two things sit outside the average.
What does it do without you?
Does it keep doing it?
What does it ask of you?
Applied after the average
A no-compensation floor is a rule in the Robovations Score that stops a strength in one area from making up for a weakness in another. It caps a robot’s score when a pillar, or its support record, falls below a set level.
Published beside it, never averaged in
A robot’s data posture describes how much the robot depends on its maker’s cloud to work, and where its data goes. Robovations places every robot in one of four postures: local, cloud-optional, cloud-linked or cloud-dependent.
The words on the box, and what each one commits the robot to.
“Self-cleaning”
Self-cleaning, in consumer robotics marketing, describes dock features that reduce owner maintenance: self-emptying bins, mop washing, mop drying, and brush detangling.
Robot Self-Cleaning Claims“Avoids obstacles”
Robot obstacle avoidance is a robot's ability to detect objects in its path and change course before contact.
Robot Obstacle Avoidance“Unlock more with a plan”
A robot subscription gate is a paid software, cloud, support, or feature limitation that changes how much capability a robot owner receives after purchase.
Robot Subscription Gate“Gets better with updates”
A robot firmware update is a manufacturer-issued software change to a robot already in owners' homes.
Robot Firmware Update“Wire-free”
A robot mower boundary wire is a physical perimeter wire, buried or pegged at the lawn edge, that tells a robot mower where it may operate.
Robot Mower Boundary Wire“Cordless”
Robot pool cleaner battery replacement is the periodic renewal of the battery pack in a cordless pool robot.

Robot Vacuums · 255 classified · Levels II – IV
Robot vacuum autonomy is how much floor cleaning a robot vacuum completes without human help: mapping rooms, avoiding obstacles, servicing itself at the dock, and recovering when it gets stuck.
Robot Lawn Mowers · 128 classified · Levels II – IV
Robot mower autonomy is how much lawn care a robot mower completes without human setup or rescue.
Robot Pool Cleaners · 75 classified · Levels II – IV
Robot pool cleaner autonomy is how much of the cleaning cycle a pool robot completes on its own: navigating the pool, climbing walls, and managing its battery.
Humanoid Robots · 65 classified · Levels I – III
Humanoid robot readiness is an assessment of whether a humanoid robot is safe, useful, recoverable, and practical in an ordinary home, as opposed to a controlled demonstration.
The terms behind every record: how sure we are, when a level moves, and what counts as a rescue.
All 16 definitions, and the other names people use for them.
Live data
Every published robot, by kind and by level. The darker the cell, the larger its share of that row. Nothing here is estimated.
