  • the reference standing posture is a posture of the holding unit 13 in a state in which the forearm of the person being assisted M1 is supported in a state where the virtual person being assisted is standing.
  • the operation trajectory Tas1 of the shoulder of the person being assisted M1 is indicated by a broken line in FIG. That is, the person being assisted M1 stands while tilting forward.
  • the control device 17 controls the drive motor 45 as a vertical movement actuator and the drive motors 32a1 and 32b1 as tilt actuators based on various information.
  • the control device 17 includes a first control unit 17a, a correction unit 17b, and a second control unit 17c.
  • the first control unit 17a determines an input of an operation to the vertically moving operation unit 15c by the person being assisted M1 or the assistant (S11).
  • the first control unit 17a controls the drive motor 45 as a vertical movement actuator according to the vertical movement operation when an operation to the vertical movement operation unit 15c is input (S12).
  • the first control unit 17a activates the drive motor 45.

  • the height of the forearm of the person being assisted M1 in the sitting state varies depending on the height of the seating part and the physique of the person being assisted M1. Therefore, the height of the holding unit 13 easily matches the height of the forearm of the person being assisted M1 when the person being assisted M1 or the person performing the operation of the vertical movement operation part 15c.
  • the correction unit 17b corrects the reference operation trajectory stored in the storage device 16 based on the vertical position of the holding unit 13 moved by the first control unit 17a and the height of the person being assisted M1. As shown in FIG. 10, the correction unit 17b acquires the vertical position of the holding unit 13 in the state operated by the first control unit 17a (S21). Next, the correction unit 17b acquires the height of the person being assisted M1 acquired by the height acquisition unit 15d (S22), and acquires the motion trajectory stored in the storage device 16 (S23).
  • the correction unit 17d corrects the motion trajectory stored in the storage device 16 based on the acquired information. For example, as shown in FIG. 12, the person being assisted M1 is sitting on a high seating portion, and the person who is assisted by the standard physique M1 whose height is stored in the storage device 16 is stored in the storage device 16.
  • the movement locus Tas2 of the shoulder portion of the person being assisted by the corrected movement locus of the actuator is the movement locus indicated by the solid line.

  • the second control unit 17e controls the driving motor 45 as the vertical movement actuator and the driving motors 32a1 and 32b1 as the tilting actuators based on the operation trajectory of the actuator corrected by the correction unit 17d.
  • the second control unit 17e determines whether or not the standing start switch 15e is ON (S31). If the standing start switch 15e is ON, the second controller 17e determines whether or not the body detection switch 66 is ON (S32). The state in which the body detection switch 66 is ON is a state in which the person being assisted M1 leans against the body detection switch 66. If any of the above determinations is not satisfied, the second control unit 17e repeats the process from S31 again. That is, since the second control unit 17e performs a standing operation when the body detection switch 66 is ON, a stable standing operation of the person being assisted M1 can be realized.
  • the second control unit 17e acquires the operation locus of the actuator corrected by the correction unit 17d (S33). Subsequently, the second control unit 17e acquires each load detected by the pressure sensor 63a (S34), and performs standing-up control according to the corrected operation trajectory and load of the actuator. For example, when the person being assisted M1 tilts greatly forward, the second control unit 17e performs control to restrict the anteversion of the person being assisted M1. In addition, when the person being assisted M1 is greatly inclined backward, the second control unit 17e performs control to restrict the backward inclination of the person being assisted M1. The second control unit 17e repeats the processes of S34 and S35 until it reaches the standing position, and ends the process when it reaches the standing position (S36).
  • the position of the holding part 13 can be moved to an arbitrary position while the person being assisted M1 is seated.
  • the movement locus of the actuator for moving to a predetermined standing posture is corrected according to the vertical position of the holding unit 13 that has been moved. That is, the start position to move to the standing posture is freely determined according to the sitting height of the person being assisted M1 and the physique of the person being assisted M1. In particular, since the start position is freely determined at an arbitrary position by the operation of the person being assisted M1 or the assistant, the operability is improved and the standing operation is stably performed.
  • the physique here refers to the length of the trunk of the person being assisted M1, the size of the buttocks, the length of the upper arm, and the like. Further, the operation trajectory of the actuator is corrected according to the height of the person being assisted M1.
