Abstract: An assistance apparatus includes a first and second wires coupling an upper-body belt and a left knee belt to each other on or above a front and back parts of a body of a user, respectively, a third and fourth wires coupling the upper-body belt and a right knee belt to each other on or above the front and back parts, respectively, a motor, a first sensor that detects at least tensions of the first and third wires, and a control circuit. The control circuit controls the motor to generate, when the first wire is broken, in the second wire, a tension less than a tension of the second wire during no break in the first wire, and to generate, when the third wire is broken, in the fourth wire, a tension less than a tension of the fourth wire during no break in the third wire.

Abstract: An assistance apparatus includes first to eighth wires that couple an upper body belt to be worn on an upper body of a user to a first knee belt and a second knee belt to be worn above a left knee and a right knee of the user, respectively, and a motor. In a case of assisting the user in moving to turn left, the motor generates a tension larger than or equal to a first threshold in each of the second wire, the third wire, and the fourth wire at an identical timing in a swing phase of a left leg of the user, and generates a tension larger than or equal to the first threshold in each of the fifth wire, the sixth wire, and the eighth wire at an identical timing in a swing phase of a right leg of the user.

Abstract: An assist device includes an upper-body belt attached to the upper body of a user, first and second belts attached to the knees, a first wire coupling the upper-body belt to the first belt, a second wire crossing the first wire, a third wire coupling the upper-body belt to the second belt, a fourth wire crossing the third wire, and a motor coupled to one end of each of the first to fourth wires. When assisting users with walking, tensions equal to a first threshold value or greater are applied to one of the first and second wires and one of the third and fourth wires by the motor at different times. When detecting slacking of the upper-body belt, tensions equal to the first threshold value or greater are simultaneously applied to one of the first and second wires and one of the third and fourth wires by the motor.

Abstract: Motor control system (10) includes position detection device (14), controller (12), and motor control device (16). Motor control device (16) includes a shift amount calculation unit that calculates a predicted arrival position of moving unit (50) based on positional information indicating a position of moving unit (50) detected by using position detection device (14) and distance information indicating a future moving distance of moving unit (50) based on an operation command, calculates a shift amount between the predicted arrival position and a target position of moving unit (50), and outputs information indicating the shift amount between the predicted arrival position and the target position. The shift amount calculation unit determines a reference point in time in consideration of at least one of an acquisition time required to acquire the positional information and an acquisition time required to acquire the distance information, acquires or calculates the position and the future moving distance of moving unit (50) at the reference point in time, and calculates the predicted arrival position based on the position and the future moving distance of moving unit (50) at the reference point in time.

Abstract: An assistance apparatus includes first to eighth wires that couple an upper body belt to be worn on an upper body of a user to a first knee belt and a second knee belt to be worn above a left knee and a right knee of the user, respectively, and a motor. When the assistance apparatus assists the user in turning left, the motor generates a tension larger than or equal to a first threshold in each of the second wire, the fourth wire, the sixth wire, and the eighth wire. When the fourth wire or the second wire is broken, the motor changes the wire in which a tension is generated.

In a case of assisting the user in turning left, the motor generates, when a left leg is in a swing phase and a right leg is in a stance phase, a tension in each of the second, third, sixth, and seventh wires at an identical timing. In a case of assisting the user in turning right, the motor generates, when the left leg is in a stance phase and the right leg is in a swing phase, a tension in each of the second, third, sixth, and seventh wires at an identical timing.
