Figure F.03 climbs a ladder autonomously in a harder humanoid mobility test

Beyond flat-ground walking

For humanoid robots to work in factories, homes, and hazardous sites, they need mobility skills beyond clean floors. Figure founder Brett Adcock wrote on X: "F.03 can now climb a ladder, fully autonomous." The source video is available on X.

The text is short, but the signal is concrete. FxTwitter data shows the post was created on August 1, 2026 at 15:30 UTC and includes a roughly 44-second video. At review time it had 5,367 likes, 485 reposts, and about 399,941 views, and the Figure_robot account had reposted it. This is not a formal product release; it is a founder-led capability demonstration.

Ladder climbing is difficult because it combines perception, hand placement, foot placement, body balance, and timing in a narrow physical structure. A missed rung or unstable grip can make the entire behavior fail. Recent robotics papers treat ladder climbing as a challenging benchmark for whole-body control because sparse footholds and handholds leave little margin for error. That is why the Figure F.03 clip matters more than another walking video: it points to a wider mobility envelope for industrial inspection, warehouse work, emergency response, and other built environments where ladders remain common.

Adcock’s account regularly surfaces Figure progress before it appears in longer company materials. The next thing to watch is repeatability. Figure will need to show different ladder angles, lighting conditions, rung shapes, payloads, and recovery from slips or blocked placements before the demo becomes strong evidence for field deployment.
