Abstract

Claims (59)

1 . A system comprising:

a walking assist device worn by a user; and

an electric moving device configured to:

set a height of a grip of the electric moving device and a height of a seat of the electric moving device that allow seating of the walking assist device based on setting information received from the walking assist device; and

set an operating speed of the electric moving device that corresponds to an operating speed of the walking assist device,

wherein the grip is configured to move up or move down from a grip housing,

wherein after a control operation for a seating start posture is completed, the electric moving device is configured to perform a control operation for a moving start posture in response to a seating of the walking assist device being completed, and

wherein the electric moving device is configured to set a speed for moving down the grip corresponding to a speed for moving the walking assist device as the seat is tilted, so that the electric moving device sets a speed for controlling the electric moving device to be in the moving start posture corresponding to a speed for controlling the seating of the walking assist device.

2 . The system of claim 1 , wherein the walking assist device comprises:

an input device configured to receive the setting information from the user; and

a controller configured to control a first leg part, a second leg part, and a third leg part.

3 . The system of claim 2 , wherein the electric moving device is configured to perform a control operation for a seating standby posture in response to receiving the setting information.

4 . The system of claim 3 , wherein the electric moving device is configured to:

set the height of the grip based on a length of the first leg part, a length of the second leg part, and a length of the third leg part; and

set the height of the seat based on the length of the third leg part.

5 . The system of claim 4 , wherein the electric moving device is configured to determine whether the height of the grip and the height of the seat are heights that allow seating of the walking assist device during performance of the control operation for the seating standby posture.

6 . The system of claim 5 , wherein the electric moving device is configured to reset the height of the grip and the height of the seat in response to a determination that the height of the grip and the height of the seat are not the heights that allow the seating of the walking assist device.

7 . The system of claim 5 , wherein the electric moving device is configured to perform the control operation for the seating start posture in response to a determination that the height of the grip and the height of the seat are the heights that allow the seating of the walking assist device.

8 . The system of claim 7 , wherein the electric moving device is configured to perform the control operation for the seating start posture by tilting the seat to allow seating of the walking assist device.

9 . The system of claim 2 , wherein the electric moving device is configured to:

control the height of the grip to be matched with a sum of a length of the first leg part and a length of the third leg part; and

recover a tilting of the seat to perform the control operation for the moving start posture.

10 . The system of claim 2 , wherein the electric moving device is configured to perform a control operation for a stand-up standby posture in response to a user input being made in a state that the electric moving device is in the moving start posture.

11 . The system of claim 10 , wherein the electric moving device is configured to:

set the height of the grip based on a length of the first leg part and a length of the third leg part; and

set the height of the seat based on the length of the third leg part to perform the control operation for the stand-up standby posture.

12 . The system of claim 11 , wherein the electric moving device is configured to determine whether the height of the grip and the height of the seat are heights that allow standing-up of the walking assist device during performance of the control operation for the stand-up standby posture.

13 . The system of claim 12 , wherein the electric moving device is configured to reset the height of the grip and the height of the seat in response to a determination that the height of the grip and the height of the seat are not the heights that allow the standing-up of the walking assist device.

14 . The system of claim 1 , wherein the electric moving device is configured to reset a moving speed of the electric moving device based on a walking speed per step of the walking assist device in response to the moving speed of the electric moving device not being matched with the walking speed of the walking assist device.

15 . The system of claim 1 , wherein the electric moving device is configured to:

set the height of the grip of the electric moving device and the height of the seat of the electric moving device that allow the seating of the walking assist device based on body information of the user; and

set a moving speed of the electric moving device to correspond to a walking speed of the walking assist device.

16 . A device comprising:

a communication device configured to receive setting information of a user from a walking assist device; and

a controller configured to:

set a height of a grip and a height of a seat that allow seating of the walking assist device based on the setting information; and

set an operating speed of the device that corresponds to an operating speed of the walking assist device,

wherein the grip is configured to move up or move down from a grip housing,

wherein after a control operation for a seating start posture is completed, the device is configured to perform a control operation for a moving start posture in response to a seating of the walking assist device being completed, and

wherein the device is configured to set a speed for moving down the grip corresponding to a speed for moving the walking assist device as the seat is tilted, so that the device sets a speed for controlling the device to be in the moving start posture corresponding to a speed for controlling the seating of the walking assist device.

17 . A device comprising:

an input device configured to receive setting information of a user; and

a controller configured to control operations of a first leg part, a second leg part, and a third leg part to assist walking of the user, as the device is worn by the user,

wherein the device further comprises a communication device,

wherein the communication device is configured to transmit the setting information to an electric moving device,

wherein the electric moving device is configured to set a height of a grip and a height of a seat that allow seating of the device based on the setting information,

wherein the grip is configured to move up and move down from a grip housing,

wherein after a control operation for a seating posture is completed, the electric moving device is configured to perform a control operation for a moving start posture in response to a seating of the device being completed, and

wherein the electric moving device is configured to set a speed for moving down the grip corresponding to a speed for moving the device as the seat is tilted, so that the electric moving device sets a speed for controlling the electric moving device to be in the moving start posture corresponding to a speed for controlling the seating of the device.

18 . A method comprising:

setting a height of a grip and a height of a seat of an electric moving device that allow seating of a walking assist device worn by a user based on setting information received by the electric moving device from the walking assist device; and

setting an operating speed of the electric moving device that corresponds to an operating speed of the walking assist device,

wherein the grip is configured to move up or move down from a grip housing,

wherein after a control operation for a seating start posture is completed, the electric moving device is configured to perform a control operation for a moving start posture in response to a seating of the walking assist device being completed, and

wherein the electric moving device is configured to set a speed for moving down the grip corresponding to a speed for moving the walking assist device as the seat is tilted, so that the electric moving device sets a speed for controlling the electric moving device to be in the moving start posture corresponding to a speed for controlling the seating of the walking assist device.

19 . The method of claim 18 , further comprising:

setting a height of the grip based on a length of a first leg part, a length of a second leg part, and a length of a third leg part.

20 . The method of claim 18 , further comprising:
