Abstract
A walking assist device evaluates the degree of asymmetry between a left motion oscillator, which is a waveform signal indicative of the time-dependent change form of an output of a left hip joint angle sensor, and a right motion oscillator, which is a waveform signal indicative of the time-dependent change form of an output of a right hip joint angle sensor. In order to reduce the degree of asymmetry, the value of at least one of a left bending coefficient, a left stretching coefficient, a right bending coefficient, and a right stretching coefficient is adjusted.
