A posture control system for a mobile robot. When an unexpected external force acts, the system is configured to control and stabilize the posture of the robot driving an arm link such that, in response to a first external force that is a component in a predetermined direction of an unexpected external force, a second external force acts on the arm link in a direction orthogonal to the predetermined direction. With this, when the mobile robot receives a reaction force, even if the posture becomes unstable or the robot receives an unexpected reaction force, it becomes possible to preserve the dynamic balance and to maintain a stable posture.

In a posture control system of a mobile robot, when unexpected external force acts, it is configured to control to stabilize the posture of the robot driving the arm link such that, in response to a first external force that is a component in a predetermined direction of the unexpected external force, a second external force acts on the arm link in a direction orthogonal to the predetermined direction. With this, when the mobile robot is controlled to work that is likely to receive a reaction force from the object, even if the posture becomes unstable or the robot receives the unexpected reaction force acting from the object, it becomes possible to preserve the dynamic balance and to maintain a stable posture.
