Featured topics
Embodied AI
How bodies, environments, perception, and action shape intelligent behavior in robots and simulated agents.
02 / TopicHumanoids
A grounded guide to human-shaped robots, their design tradeoffs, applications, and the evidence needed to evaluate progress.
03 / TopicFoundation Models
An introduction to broadly trained models for robot perception, planning, language grounding, and action.

What Did the Robot Test Actually Hold Out?
A practical audit of robot training, validation, and test splits, covering episodes, sites, objects, preprocessing, checkpoint selection, and generalization claims.
Audit the dataset split →Evidence first
One successful clip is not a denominator.
Check autonomy, edits, attempts, resets, speed, variation, failures, and operating evidence before repeating a robot claim.
Evaluate a demonstration →Latest developments
A robot video is evidence, but its scope matters.
A demonstration can establish a real behavior without establishing repeatability, autonomy, useful speed, or production readiness.
Preserve the complete denominator: attempts, control modes, interventions, resets, time, variation, failures, and accepted output.

Independent research
Evaluating a robot, vendor, or deployment claim?
Commission a source-conscious evidence brief, vendor comparison, or deployment-readiness review for a real decision.
