Abstract:
A robot includes an arm mechanism that operates in accordance with a first motion pattern for supporting a user with a standing-up motion which starts in a sitting posture and finishes in a standing posture, a control unit that (i) acquires first information used to identify a predetermined position of the arm mechanism corresponding to a half-crouching posture of the user during a motion in accordance with the first motion pattern and (ii) detects whether the current position of the arm mechanism operating in accordance with the first motion pattern is included in a first range including the predetermined position identified by the first information, and a presentation unit that presents a first signal if the control unit detects that the position of the arm mechanism is included in the first range.
Abstract:
A holding mechanism holds a care-receiver, a traction mechanism that is connected to the holding mechanism, and the traction mechanism pulls the holding mechanism so that the holding mechanism draws a predetermined path. On the basis of a position of the holding mechanism detected by a position sensor and a force detected by a force sensor, if the position of the holding mechanism is not on the predetermined path, a controller controls the traction mechanism so that the holding mechanism draws the predetermined path by changing the position of the holding mechanism to a position on the predetermined path at a time after the time at which the position is detected.
