Cassie

Oregon State's underactuated bipedal robot designed by Jonathan Hurst, direct precursor to Agility Robotics' Digit humanoid. Features passive dynamic walking.

Cassie is at the research stage: it exists, but DEPLOY has no verified real-world deployment on record. Manufacturer capability claims should be read as claims pending independent verification.

Cassie is made by Oregon State Dynamic Robotics Lab, based in Corvallis, OR, USA.

Cassie is at research stage and is not yet available for sale.

On the DEPLOY registry, comparable humanoid robots to Cassie include Walker S2, Digit, Unitree G1, Atlas.

Cassie and Walker S2 (UBTech Robotics · 18 deployments) are both humanoid robots on the DEPLOY registry. Cassie has 0 verified deployments on record. Compare both records for specs, safety, deployments, and verified-vs-claimed autonomy.

On DEPLOY's intelligence score, which blends verified deployments, safety, adoption, media, and IP signals, Cassie ranks in roughly the top 76% of humanoid models tracked by the registry.

Cassie is at the research stage on the DEPLOY maturity ladder (research, prototype, pilot, commercial, production). Research stage means active development without commercial deployments on file.

No verified deployments of Cassie are currently on the DEPLOY registry. DEPLOY records deployments only when verified at a named site with a primary source; absence may reflect pre-deployment, research, or manufacturer-internal use.

Cassie has no incidents on record in the DEPLOY registry. This does not constitute a safety guarantee; it reflects the incidents DEPLOY has tracked and verified to date.
