  • Publication number: 20080240889
    Abstract: A robot or the like able to precisely grip an object by flexibly changing an operation in accordance with various environments. When it is judged that a robot is in a “first state”, the action of the robot is controlled in accordance with a “first action mode”. Thus, the robot does not move and moves an arm or the like on the spot so that a first object W1 can be gripped by a hand. On the other hand, when the judging result is denial, the robot acts in an action mode different from the first action mode so that a relative position or the like of the first object W1 with the robot as a reference is changed. As a result, the robot can be changed from a non-first state to the first state.

  • Patent number: 7378811
    Abstract: A landing shock absorbing device 18 disposed in a foot mechanism 6 of a leg of a robot, wherein an inflatable bag-like member 19 (variable capacity element) is provided at a bottom face side of the foot mechanism 6. The bag-like member 19 is constructed of an elastic material such as rubber. The air in atmosphere may flow into and out of the bag-like member 19 by inflow/outflow means 20 equipped with a solenoid valve 27, and the like. In a lifting state of the foot mechanism 6, inflow of the air into the bag-like member 19 is controlled, thereby controlling the final height of the bag-like member 19 in an inflated state to the height in response to a gait type of the robot. While properly reducing an impact load during a landing motion of the leg of a legged mobile robot depending on the gait type of the robot, stability of a posture of the robot may easily be secured, resulting in allowing a configuration to be lighter in weight.

  • Publication number: 20070135966
    Abstract: When there is an object that has a possibility to come into contact with a robot 1 in a desired path, the robot 1 is decelerated stepwise according to the distance L from the robot 1 to a predicted contact position along the desired path. For example, legs 13 and the like of the robot 1 are so controlled that when the distance L is less than a first threshold L1, the moving speed is reduced to a first speed V1, and when the distance L is less than a second threshold lower than the first threshold, the moving speed is reduced from the first speed to a second speed.

  • Patent number: 7228923
    Abstract: A landing shock absorbing device 18 disposed in a foot mechanism 6 of a leg of a robot, wherein an inflatable bag-like member 19 (a variable capacity element) is provided at a ground-contacting face side of the foot mechanism 6. The bag-like member 19 is constructed of an elastic material such as rubber and has a restoring force. An interior portion of the bag-like member 19 is communicated with the atmosphere side through a flow passage 20. During a landing motion of the leg, the bag-like member 19 makes contact with the ground to be compressed, and the air in the interior portion thereof flows out into the atmosphere through the flow passage 20, so that its outflow resistance is generated. Accordingly, a landing shock is reduced. In a lifting state of the leg, the restoring force of the bag-like member 19 allows the bag-like member 19 to be inflated while the air flows into the interior portion thereof.

  • Publication number: 20060173577
    Abstract: The content of the voice designation of a designator is recognized by a voice recognition part 130 at the time of controlling a robot, and the content of the indication of gesture or the like is recognized by an image recognition part 120. A movement destination and a map around the specific position designated are referred from a map data base 150 registering the position of an obstacle and the current position estimated by a self-position estimation part 140. After movement ease is decided by a movement ease decision part 112, the behavior is decided. When movement designation is given to the robot, correspondence according to a situation can be performed.
