What’s inside
The parts the company has talked about publicly.
- Movement
- Walks on legs
- How it runs
- Assisted. Researchers steered it while it balanced, ran and climbed stairs blind by itself using touch.
- Actuators & motors
- Electric leg motors used to sense leg forces directly (proprioceptive actuation); wider hip range than Cheetah 2
- Sensors & vision
- Blind locomotion: gyroscopes, accelerometers and joint position sensing, no cameras for walking; cameras added later for mapping
- Materials & build
- About 41 kg (90 lb), Labrador-sized
- AI & software
- Contact-detection algorithm estimating ground contact per leg, plus model-predictive control planning about half a second ahead, updated 20 times a second
- Other details
- Funded partly by Naver, Toyota Research Institute, Foxconn and the US Air Force Office of Scientific Research
