Apparatus for assisting limb and computer program
First Claim
1. An apparatus for assisting limb comprising:
- a body attachment which is attached to a trunk of a user;
a link for upper leg which is placed alongside with an upper leg of the user, the link being coupled with the body attachment;
a knee joint unit;
a link for lower leg which is placed alongside with a lower leg of the user, the link being coupled with the link for the upper leg via the knee joint unit;
a lower limb attachment which is attached to one of the lower leg and a foot of the user, the lower limb attachment being coupled with the link for lower leg;
a drive unit; and
a knee joint actuator which is placed in the body attachment so as to apply rotational torque to the knee joint unit via the drive unit.

Abstract
An apparatus for assisting limb includes a body attachment, a link for upper leg, and a knee joint unit, a link for lower leg, a lower limb attachment, a drive unit and a knee joint actuator. The body attachment is attached to a trunk of a user. The link for upper leg is placed alongside with an upper leg of the user and coupled with the body attachment. The link for lower leg is placed alongside with a lower leg of the user and coupled with the link for the upper leg via the knee joint unit. The lower limb attachment is attached to one of the lower leg and a foot of the user, and coupled with the link for lower leg. The knee joint actuator is placed in the body attachment so as to apply rotational torque to the knee joint unit via the drive unit.

21. A computer program for an apparatus for assisting limb, the apparatus comprising:
-
a controller;
a body attachment which is attached to a trunk of a user;
a link for upper leg which is placed alongside with an upper leg of the user, the link being coupled with the body attachment;
a knee joint unit;
a link for lower leg which is placed alongside with a lower leg of the user, the link being coupled with the link for the upper leg via the knee joint unit;
a lower limb attachment which is attached to a foot of the user so as to land on the ground, the lower limb attachment being coupled with the link for lower leg;
a drive unit;
a knee joint actuator which is placed in the body attachment so as to apply rotational torque to the knee joint unit via the drive unit; and
a foot detector configured to detect one of a landed phase and a lifted phase of the foot of the user, wherein the computer program executes the controller in a process comprising performing drive control for the knee joint actuator so as to provide an assist force freeing the user from weight via the lower limb attachment in a landed phase, the link for lower leg, the link for upper leg, the drive unit and the body attachment. - View Dependent Claims (22, 23, 24, 25)

26. A computer program for an apparatus for assisting limb, the apparatus comprising:
-
a controller;
a body attachment which is attached to a trunk of a user;
a hip joint unit;
a link for upper leg which is placed alongside with an upper leg of the user, the link being coupled with the body attachment via the hip joint unit;
a knee joint unit;
a link for lower leg which is placed alongside with a lower leg of the user, the link being coupled with the link for the upper leg via the knee joint unit;
a lower limb attachment which is attached to a foot of the user so as to land on the ground, the lower limb attachment being coupled with the link for lower leg;
a drive unit;
a knee joint actuator which is placed in the body attachment so as to apply rotational torque to the knee joint unit via the drive unit;
a hip joint actuator which is integrally installed with the knee joint actuator in the body attachment so as to apply rotational torque to the hip joint unit; and
a foot detector configured to detect one of a landed phase and a lifted phase of the foot of the user, wherein the computer program executes the controller in a process comprising performing drive control for the knee joint actuator and the hip joint actuator so as to provide an assist force freeing the user from weight via the lower limb attachment in a landed phase, the link for lower leg, the link for upper leg, the drive unit and the body attachment. - View Dependent Claims (27, 28, 29, 30, 31)
