Quick walking: assistive symmetric extension with flexion angle upto 60-65 degrees 4. Stair ascending: flexion control during swing mode and assistive extension during standing mode. 5. Stair descending: natural gait with sole grounding and less buffering by yielding 6. Up hilling: natural gait with less tiptoe 7. Down hilling: yielding at any angle with safer down hilling 8.
