Energy Recycling with the Artificial Foot:
High-speed video of the energy-recycling artificial foot, played back at 6% of actual speed. Camera rate was 500 frames per second.
The foot proceeds through the phases described in cf. Figure 2, beginning prior to heel strike and ending at reset.
The foot is worn by an able-bodied individual using a below-knee prosthesis simulator boot.
This demonstration was performed overground and with less-curved versions of the crepe roll-over shapes of the artificial foot than used in testing.
Developed by Steve Collins and Art Kuo at the University of Michigan.
Video by Eno Yliniemi and Randall Ching of the University of Washington Applied Biomechanics Lab.
