- Abstract
The human body is a spring-mass-damper system that oscillates up and down while moving. Wearable robots can add energy to the person at an appropriate time to enhance human moving performance and reduce the metabolic cost of performing cyclic tasks simultaneously. We have developed a phase oscillator to add assisted power at resonance so the system attains suitable energy to overcome the vertical resistance. The oscillator is robust to disturbances and initial conditions and allows wearable robots to enhance running, reduce metabolic cost, and increase hop height. Results show that when the external force is angled at 25 degrees, the phase oscillator can maintain robust bounded energy in a limit cycle to enhance human running performance.
