Two: In the course of designing Stompy, the Project Hexapod crew developed a position-controlled hydraulic actuator capable of generating 18, 000 pounds of force with a two-foot stroke that's two orders of magnitude cheaper that comparable hardware.

Its second-generation Ankle Mimicking Prosthetic Foot (AMP-Foot 2.0) uses a pair of force sensors to determine the leg's relative position and let an actuator build energy when the foot bends, locking the power away to use only when the owner pushes off.
