Care robot
First Claim
1. A care robot, comprising:
- a holding section configured to assist a standing-upright motion and a sitting motion of a care receiver by supporting a part of the body of the care receiver;
a base;
a robot arm section that is provided in the base, and includes multiple arms which are mutually and relatively movable by using a drive section;
the holding section that is provided in a distal end portion of the robot arm section, and supports the care receiver;
a memory section that stores standing-upright trajectory reference data of the holding section, and sitting trajectory reference data of the holding section which is different from the standing-upright trajectory, and along which the movement control portion of the care receiver moves when the care receiver sits with the support of the holding section;
a handle configured to be gripped by hands of the care receiver, the handle including a first contact sensor to detect a first hand of the care receiver and a second contact sensor to detect a second hand of the care receiver; and
a drive control section configured to drive the drive section such that the robot arm section is driven based on the standing-upright trajectory reference data and the sitting trajectory reference data,wherein when the sitting care receiver stands upright with the support of the holding section, a standing-upright trajectory of the holding section, is set,wherein when the standing care receiver sits with the support of the holding section, a sitting trajectory of the holding section, which is different from the standing-upright trajectory, is set,wherein the sitting trajectory of the holding section is above the standing-upright trajectory of the holding section, andwherein the holding section performs the standing-upright motion when the first contact sensor detects the first hand, in response to a first guidance by the care robot.

Abstract
A care robot that assists a standing-upright motion or a sitting motion of a care receiver without making the care receiver uncomfortable. In the care robot, a standing-upright trajectory, along which a movement control portion of a care receiver moves, is set so a center of gravity of the care receiver is in a range of the soles of both feet between a point in time early after the start of a standing-upright motion and an end time point of the standing-upright motion of the care receiver. A sitting trajectory is set so the center of gravity of the care receiver is out of the range of the soles of both feet from a point in time early after the start of a sitting motion of the care receiver, and moves toward a predetermined sitting position of the care receiver.

8. A care robot, comprising:
-
a holding section configured to assist a standing-upright motion and a sitting motion of a care receiver by supporting a part of the body of the care receiver, wherein when the sitting care receiver stands upright with the support of the holding section, a standing-upright trajectory of the holding section is set such that a center of gravity of the care receiver is present in the range of the soles of both feet between a point in time early after the start of the standing-upright motion and an end time point of the standing-upright motion of the care receiver, wherein when the standing care receiver sits with the support of the holding section, a sitting trajectory of the holding section, which is different from the standing-upright trajectory, is set such that the center of gravity of the care receiver is present out of the range of the soles of both feet from a point in time early after the start of the sitting motion of the care receiver, and moves toward a predetermined sitting position of the care receiver, wherein the sitting trajectory of the holding section is above the standing-upright trajectory of the holding section. - View Dependent Claims (9)

10. A care robot, comprising:
-
a holding section configured to assist a standing-upright motion and a sitting motion of a care receiver by supporting a part of the body of the care receiver, wherein when the sitting care receiver stands upright with the support of the holding section, a standing-upright trajectory of the holding section is set, wherein when the standing care receiver sits with the support of the holding section, a sitting trajectory of the holding section, which is different from the standing-upright trajectory, is set, wherein the standing-upright trajectory of the holding section is above the sitting trajectory of the holding section.
