Abstract

A system for enabling a mobile robot to utilize an elevator autonomously comprises a pressing module including at least one pressing finger adapted to press elevator call buttons on an elevator call control panel. A lifting device of the system supports the pressing module and selectively adjusts a height position of the pressing module for aligning the at least one pressing finger on the pressing module to height positions horizontally aligned with the elevator call buttons. A controller wirelessly communicates with the mobile robot and the pressing module. In response to a command sent by the mobile robot, the controller instructs the pressing module to press an elevator call button on the elevator call control panel associated with the command.

Claims (32)

1 . A system for enabling a mobile robot to utilize an elevator autonomously, comprising:

a pressing module including a housing having a plurality of pressing fingers provided within the housing for pressing elevator call buttons on an elevator call control panel, the plurality of pressing fingers selectively extend and/or retract in and out of the housing to press the elevator call buttons;

a lifting device supporting the housing of the pressing module and selectively adjusting a height position of the pressing module for aligning at least one pressing finger of the plurality of pressing fingers on the pressing module to height positions horizontally aligned with the elevator call buttons; and

a controller for wirelessly communicating with the mobile robot and the pressing module, the controller, in response to a command sent by the mobile robot, controlling the pressing module to press an elevator call button on the elevator call control panel associated with the command.

2 . The system according to claim 1 , wherein the pressing module automatically retracts at least one of the plurality of pressing fingers into the housing under the action of an elastic reset mechanism after completing the pressing action.

3 . The system according to claim 1 , wherein a rear surface of the housing facing the elevator call control panel includes a plurality of openings through which the plurality of pressing fingers pass as they extend out of the housing to press the elevator call buttons.

4 . The system according to claim 1 , wherein the pressing module further comprises a plurality of pressing buttons provided on a front surface of the housing facing away from the elevator call control panel, the pressing module, in response to one of the pressing buttons being pressed, driving the at least one pressing finger to press the elevator call button of the elevator call control panel corresponding to the pressed pressing button.

5 . The system according to claim 4 , wherein the pressing module further comprises a human-machine interaction interface provided on the front surface of the housing for displaying working information of the pressing module.

6 . The system according to claim 4 , wherein the elevator call buttons include an up button and a down button provided on the elevator call control panel, and the at least one pressing finger includes a first pressing finger for pressing the up button and a second pressing finger for pressing the down button.

7 . The system according to claim 6 , wherein the pressing module is adapted to, in response to the mobile robot sending a command to press the up button, drive the first pressing finger to press the up button under control of the controller, the pressing module is further adapted to, in response to the mobile robot sending a command to press the down button, drive the second pressing finger to press the down button under control of the controller.

8 . The system according to claim 7 , wherein the pressing buttons comprise a first pressing button corresponding to the up button and a second pressing button corresponding to the down button.

9 . The system according to claim 8 , wherein the pressing module is further adapted to, in response to the first pressing button being pressed, drive the first pressing finger to press the up button, and in response to the second pressing button being pressed, drive the second pressing finger to press the down button.

10 . The system according to claim 6 , wherein a distance between the first pressing finger and the second pressing finger is adjustable to accommodate different elevator call control panels.

11 . The system according to claim 1 , wherein the lifting device includes a liftable telescopic rod supporting the pressing module on an end thereof.

12 . The system according to claim 11 , wherein the lifting device further includes a support plate fixed on the top end of the telescopic rod, and the pressing module is fixed on the support plate.

13 . The system according to claim 12 , wherein the system further includes a base, and the lifting device and the controller are mounted on the base.

14 . The system according to claim 13 , wherein the lifting device is an electronically controlled hydraulic cylinder or an electronically controlled cylinder, and the controller is further adapted to control an ascending or descending distance of the lifting device so as to adjust the height position of the pressing module.

15 . The system according to claim 13 , wherein the system further comprises a pair of fixed support columns fixed on the base, the pair of fixed support columns being located below two ends of the support plate respectively for supporting the supporting plate at a predetermined height position.

16 . The system according to claim 15 , wherein the lifting device is provided between the pair of fixed support columns and located below a middle position of the support plate.

17 . The system according to claim 1 , wherein the pressing module further comprises a driving mechanism provided within the housing and adapted to drive the plurality of pressing fingers, each pressing finger defines a moveable free end of the driving mechanism.

18 . A system for enabling a mobile robot to take an elevator autonomously, comprising:

a plurality of autonomous elevator systems, each system positioned in front of an elevator call control panel at a plurality of floors accessible by an elevator car of the elevator, each system comprising:

a pressing module including a pressing finger adapted to press elevator call buttons on an elevator call control panel;

a lifting device supporting the pressing module for selectively adjusting a height position of the pressing module for aligning the pressing finger on the pressing module to height positions horizontally aligned with the elevator call buttons; and

a controller adapted to wirelessly communicate with the mobile robot and the pressing module, the controller, in response to a command sent by the mobile robot, controlling the pressing module to press predetermined elevator call buttons on the elevator call control panel, the mobile robot sends a first command to press an elevator call button to one of the plurality of autonomous elevator systems positioned on a departure floor, and upon entering the elevator car at the departure floor, sends a second command to press an elevator call button to another one of the plurality of autonomous elevator systems positioned on a destination floor for moving the elevator car to the destination floor.

19 . A system for enabling a mobile robot to utilize an elevator autonomously, comprising:

a pressing module including at least one pressing finger for pressing elevator call buttons on an elevator call control panel;

a lifting device supporting the pressing module and selectively adjusting a height position of the pressing module for aligning the at least one pressing finger on the pressing module to height positions horizontally aligned with the elevator call buttons, the lifting device includes a liftable telescopic rod supporting the pressing module on an end thereof and a support plate fixed on a top end of the telescopic rod, the pressing module is fixed on the support plate;

a base on which the lifting device and the controller are mounted; and

a pair of fixed support columns fixed on the base, the pair of fixed support columns being located below two ends of the support plate respectively for supporting the supporting plate at a predetermined height position.

20 . The system according to claim 19 , wherein the lifting device is provided between the pair of fixed support columns and located below a middle position of the support plate.
