Handshake legged mobile robot control system
First Claim
1. A system for controlling a legged mobile robot having a body, legs and arms each connected to the body, leg actuators each driving the individual legs and arm actuators each driving the individual arms, the system comprising:
- a force sensor detecting an external force acting on each of the arms;
an arm operation controller controlling operation of at least one of the arm actuators such that one of the arms produces a handshake posture; and
a leg operation controller controlling operation of the leg actuators based on the detected external force acting on the one of the arms producing the handshake posture,wherein the leg operation controller controls operation of the leg actuators so as to move the robot in a same direction as that of the external force, when the detected external force exceeds a predetermined value, wherein the detected external force is caused by a person shaking a hand of the one of the arms.

Abstract
In a legged mobile robot control system having leg actuators each driving the individual legs and arm actuators each driving the individual arms, an external force acting on the right arm is detected, operation of the right arm actuators is controlled to produces a handshake posture, and operation of the leg actuators is controlled based on the detected external force acting on the right hand during handshaking, thereby improving communication capability by enabling it to shake hands with humans and to maintain a stable posture during the handshaking.

7. A method of controlling a legged mobile robot having a body, legs and arms each connected to the body, leg actuators each driving the individual legs and arm actuators each driving the individual arms, the method comprising the steps of:
-
detecting an external force acting on each of the arms; controlling operation of at least one of the arm actuators such that one of the arms produces a handshake posture; and controlling operation of the leg actuators based on the detected external force acting on the one of the arms producing the handshake posture, wherein the step of leg operation controlling controls operation of the leg actuators so as to move the robot in a same direction as that of the external force, when the detected external force exceeds a predetermined value, wherein the detected external force is caused by a person shaking a hand of the one of the arms. - View Dependent Claims (8, 9, 10, 11, 12)
