## Common questions

### What is Cassie?

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

### How much does Cassie cost?

Cassie's price is not publicly disclosed. DEPLOY has no verified price on record for Cassie from Oregon State Dynamic Robotics Lab. Physical-AI systems like this are often sold through enterprise contracts or operated as a service rather than at a public list price; check the manufacturer for the latest.

### Is Cassie actually deployed in the real world?

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.

### Who makes Cassie?

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

### Can you buy Cassie?

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

### What are alternatives to Cassie?

On the DEPLOY registry, comparable humanoid robots to Cassie include Walker S2, Digit, HMND 01 Alpha Wheeled, Robody.

### How does Cassie compare to Walker S2?

Cassie and Walker S2 (UBTech Robotics · 13 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.

### What is Cassie's maturity stage?

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.

### Where is Cassie deployed?

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.
