Abstract:
A method of controlling an external force applied to an animal to achieve as a target relation the relation between the external force and a motion variable varying with the motion of the animal.A value of an external force f applied to a human leg according to an external force function f(x) on the basis of a measured value of a myoelectric potential x that occurs in the human leg, current I of a motor 220 is controlled according to the set value, and the external force f is applied to the leg through an orthosis 222. A resultant force (the sum of an internal torque and an external torque around a knee joint) F is measured as “a motion variable.” Moreover, a value of a factor γ is set according to a factor function γ(f, F) on the basis of the set value of the external force f and the measured value of the resultant force F. If a deviation δ between the set value of the factor γ and target value γt thereof is equal to or greater than a reference value ε, a new external force function f(x) is set in such a way that the set value of the factor γ approaches the target value γt.

A walking assistance device has a load transmitting assembly, a foot-worn assembly, and a leg link provided between the load transmitting assembly and the foot-worn assembly. The foot-worn assembly has a ground contact member, on which a user's foot rests, and a connecting member which connects the ground contact member to a joint at a lower end of the leg link. The ground contact member is provided with tread force sensors and the foot-worn assembly permits detection of a tread force. The connecting member is formed so as to rise in a cantilever manner from one lateral side of the ground contact member. The tread force sensors are installed in at least one location adjacent to the heel of the user's foot and in at least two locations adjacent to toes of the user's foot, with the latter two locations being laterally spaced apart.

A method, system, and program enabling a variable varying with an animal's motions to be accurately measured. First, a reference relational expression representing a relation between myoelectric potentials and motion is set on the basis of the myoelectric potentials and the variable measured by using an inverse dynamics model. Then, the motion variable is measured on the basis of the measured myoelectric potentials and according to the reference relational expression. A reference relational expression is set on the basis of myoelectric potentials measured in a first motion and a motion variable corresponding to the first motion. Then, a motion variable corresponding to a second motion is measured on the basis of the myoelectric potentials measured in the second motion and according to the reference relational expression.
Abstract:
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.
Abstract:
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).
Abstract:
A device capable of assisting an agent in taking a step even in the case where the leg motion of the agent is stagnant. It is determined whether the agent is in a first state in which the leg of the agent is moving or in a second state in which the leg of the agent is stagnant, on the basis of a value detected in response to the leg motion of the agent. If a transition from the first state to the second state is detected as the determination result, a value of a sustained energy input term is increased, where the sustained energy input term is contained in a simultaneous differential equation representing a second model for use in generating a second oscillator ξ2, which is to be a control basis of an assisting force.
