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 turning left, the motor generates, when a right leg of the user is in a stance phase, a tension larger than or equal to a first threshold in each of the second, fourth, sixth, and eighth wires at an identical timing. In a case of assisting the user in turning right, the motor generates, when a left leg of the user is in a stance phase, a tension larger than or equal to the first threshold in each of the first, third, fifth, and seventh wires at an identical timing.

Abstract: An unmanned aircraft includes: at least two generators generating forces to fly the unmanned aircraft, each including a rotor blade generating an airflow; a sensor detecting a tilt of the unmanned aircraft; and a processor controlling the generators to control flight of the unmanned aircraft. The processor: obtains an output force adjustment trigger for the generators; obtaining the trigger, causes each generator to individually operate at least until the tilt of the unmanned aircraft detected by the sensor satisfies a predetermined condition; determines a reference value related to an output force of each generator from a value related to the output force of each generator when the tilt of the unmanned aircraft satisfies the predetermined condition and a positional relationship between the generators; and controls the flight of the unmanned aircraft, using the reference values determined.

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 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.

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 system includes a fist belt worn on an upper body part of a user, a second belt worn on a knee of the user, a wire, a motor coupled with a first end of the wire and disposed on the first or second belt, a drive controller that controls drive of the motor, a gyro sensor that is disposed on the second belt and that measures an angular velocity about a direction perpendicular to the direction of the wire, and a controller. When the angular velocity is greater than or equal to a first threshold with a first tension being applied to the wire using the motor, the controller outputs first information. A second end of the wire is coupled with the second belt when the motor is disposed on the first belt but coupled with the first belt when the motor is disposed on the second belt.

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.

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.
