Public attention
A historic robot: no longer sold or in use, so it is not ranked against current machines.

What’s inside
The parts the company has talked about publicly.
- Movement
- Walks on legs
- How it runs
- Fully autonomous. In its best-known demonstration it spotted hurdles with lidar and planned and made the jumps by itself; it was also steered by researchers in other runs.
- Actuators & motors
- Custom high-torque-density electric motors (designed by Jeffrey Lang) with amplifiers by David Otten; force on the ground is controlled without foot force sensors
- Sensors & vision
- Onboard lidar maps obstacles for the jumping algorithm (2015)
- Battery & power
- Battery powered and untethered; capacity not published
- AI & software
- Bounding gait algorithm; three-part lidar-based obstacle detection and jump planning
- Other details
- Ran up to about 10 mph indoors; cleared obstacles up to 18 inches while running; DARPA funded
