Abstract: An assistance apparatus includes a first wire and a second wire that couple an upper-body belt and a left knee belt to each other on or above a front part and back part of the body of a user, respectively, a third wire and a fourth wire that couple the upper-body belt and a right knee belt to each other on or above the front part and back part of the body of the user, respectively, a motor, a left sensor on the left hand of the user, and a right sensor on the right hand of the user. When a force is applied to the left sensor and no force is applied to the right sensor, the motor makes the tension of the second wire and the third wire greater than the tension of the first wire and the fourth wire. When a force is applied to the right sensor and no force is applied to the left sensor, the motor makes the tension of the first wire and the fourth wire greater than the tension of the second wire and the third wire.

Abstract: In an assistance apparatus, when assisting a user in walking with an object, a motor generates, in a gait phase of a left leg, a tension less than a second threshold value in a first wire during a fifth period other than a first period during which a tension greater than or equal to a first threshold value is generated in the first wire, and a tension greater than or equal to the second threshold value in a second wire during a sixth period other than a second period during which a tension greater than or equal to the first threshold value is generated in the second wire, and generates, in a gait phase of a right leg, a tension less than the second threshold value in a third wire during a seventh period other than a third period during which a tension greater than or equal to the first threshold value is generated in the third wire, and a tension greater than or equal to the second threshold value in a fourth wire during an eighth period other than a fourth period during which a tension greater than or equal to the first threshold value is generated in the fourth wire.

Abstract: A walking assistance apparatus includes a knee fastener, a heel fastener, a first wire and a second wire connected to the knee fastener and the heel fastener, a first motor connected to the first wire, a second motor connected to the second wire, and a control circuit that controls the first motor and the second motor. The first wire is connected to a first position included in a right-half region of the heel fastener. The second wire is connected to a second position included in a left-half region of the heel fastener. The control circuit acquires gait information of the user, and, based on the gait information, the control circuit controls the first motor to reduce a length of the first wire and the second motor to reduce a length of the second wire at a predetermined timing.

Abstract: An assistance apparatus includes wires, each of which couples an upper-body belt and one of left and right knee belts to each other, and a motor. To promote implementation of first assistance for a user in walking while carrying an object, the motor generates a tension greater than or equal to a third threshold value in a second wire and a fourth wire, a tension greater than or equal to the third threshold value in the second wire and a third wire, and a tension greater than or equal to the third threshold value in a first wire and the fourth wire. During execution of the operation described above, upon receipt of determination of implementation, to indicate that implementation of the first assistance is determined, the motor generates a tension greater than or equal to a fourth threshold value in the second wire and the fourth wire, a tension greater than or equal to the fourth threshold value in the second wire and the third wire, and a tension greater than or equal to the fourth threshold value in the first wire and the fourth wire.

Abstract: An assist wear item is worn on a portion of a living body and has an inner surface brought into contact with the portion. The assist wear item includes assisting actuators, contact sensors, and a controller. Each assisting actuator is driven to expand and contract. The assisting actuators are linearly arranged along an expansion/contraction direction of a muscle at the portion. Each contact sensor detects a contact with an outer surface of the assist wear item. The contact sensors include a first contact sensor and a second contact sensor. The controller increases or decreases a driving power of expansion/contraction driving of an assisting actuator corresponding to a region ranging from the first contact sensor to the second contact sensor if the controller continuously receives a detection result indicating a contact from at least one contact sensor between the first and second contact sensors during a certain time period.
