# Multi-axis modular coupling system for mobile robot

## Abstract

Disclosed is a multi-axis modular coupling system (100) for a mobile robot (102), the multi-axis modular coupling system comprises: a mounting plate (110) employed to attach to different custom modules for enabling movement of different user assets; a first degree of freedom element (202) employed to enable a translational degree of freedom (204) of said system; a second degree of freedom element (206) to enable a first rotational degree of freedom (208) of said system; and a third degree of freedom element (210) to enable a second rotational degree of freedom (212) of said system. When said system is in use, at least one of: the first degree of freedom element, the second degree of freedom element, the third degree of freedom element, operates to accommodate for floor surface irregularities when a given user asset (114) is carried by the mobile robot.
