  • Patent number: 10624809
    Abstract: The present disclosure provides a method for controlling an exoskeleton robot. The method comprises checking that a first signal is triggered by a first button, checking a tilt angle after the first signal is triggered, setting an action based on the tilt angle, and executing the action to move the exoskeleton robot. The first signal indicates to change the exoskeleton robot from a standing posture to another posture, and the tilt angle is a leaning-forward angle of a waist assembly of the exoskeleton robot relative to a line vertical to ground. The method utilizes the tilt angle to judge the intent of the user, and thus can simplify the controlling buttons to one or two buttons. Further, the controlling method also monitors the tilt angle to choose a suitable action.
