摘要:
A movement assist system for assisting stably a movement of a creature, particularly a creature whose body part is paralyzed due to neuropathy or the like. According to the movement assist system, walking movement of a human is assisted according to an output from an actuator of a movement assist device. A timing of an electrical stimulation applied to the creature is adjusted by an electrical stimulation device on the basis of a signal representing an arithmetic processing result by a first controller which controls the output of the actuator. According thereto, it is possible to apply an electrical stimulation to the human at an appropriate timing from the viewpoint of maintaining an appropriate posture by considering a periodical movement state of the human even in cases where the body function is degraded, allowing the human assisted by the movement assist device to continue the walking movement.

Provided is a device capable of assisting a periodical motion of a creature, such as a human, by applying a force to the creature so as to match a motion rhythm and a motion scale of the periodical motion to a desired motion rhythm and a desired motion scale, respectively, while reducing computation processing load. According to a motion assist device (10) of the present invention, a value of a member or a coefficient contained in a simultaneous differential equation of a state variable (ui) for defining a second model which generates a second oscillator (ξ2) is adjusted by means of an adjusting device (14). The second oscillator (ξ2) is generated by the adjusted second model and a torque (T) applied to a human (P) is controlled to vary periodically according to the second oscillator (ξ2).

A motion assist device for assisting a periodical motion of a creature such as a human by applying a force with appropriate strength to the creature so as to match a motion scale with a desired motion scale thereof regardless of a motion rhythm of the periodical motion. According to the motion assist device (1), a second model is corrected so as to approximate a value of a motion variable (ξ) to a desired value (ξ0). A second oscillator (ξ2) is generated according to the corrected second model. A periodical force (torque) (T) applied to the human (P) is controlled according to the second oscillator (ξ2).

摘要:
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.
