    摘要: A foot structure of a biped waling mobile robot having a body and two articulated legs each having a foot at its distal end. In the foot structure, a movable foot piece is housed in each foot which is driven by an actuator to be swung out to enlarge the ground contact surface. A controller provided for the actuator and based on a condition of walking such as stair descending, it controls the operation of the actuator such that the foot's ground contact surface is enlarged. The structure has another aspect in which a ratio between distances from a point at which the foot is connected to the leg to the foot ends can also be adjusted in response to the walking condition. Moreover, the foot can be arranged such that the foot is configured to have portions to be contact with the ground at its four corners and the movable foot pieces have additional contact portion enlarging or reducing the ground contact portions.

    摘要: An impact absorber for a legged mobile robot having a body and two legs each connected to the body for absorbing impact arising when the robot collides with pipes or other objects in its walking environment so as to protect both the robot and the object. In a first embodiment, the impact absorber comprises a balloon disposed around the body and filled with air. When the balloon comes into contact with the object, it is deflated so as to absorb impact arising from the contact. In a second embodiment, the impact absorber comprises a cylinder fixed to the robot leg and a piston slidably disposed in the cylinder so as to define a chamber filled with an oil. A flat member is fixed to the rod of the piston and when it comes into contact with the object, the piston is thrust into the cylinder so as to absorb the impact. The impact absorber may be a resilient material coating on the robot to cushion the impact when the robot comes into contact with the object, or it may include air bags.

    摘要: A legged mobile robot having a body and two legs each connected to the body. The robot is quipped with a mechanism for absorbing and moderating impacts produced by external forces during footfall or the like. The mechanism includes an elastic member interposed between the body and legs, or interposed between the leg links, or interposed between the distal end of the legs and foot portions. The robot further has a foot structure for enhancing the ground gripping force and absorbs the impacts. For enhancing the gripping force, the foot sole is provided, for example, with a first elastic member and second elastic member sandwiching a plate spring therebetween. The first elastic member absorbs the impacts, while the second elastic member enhancing the gripping force. The plate spring restrict the deformation of the elastic members in the direction vertical to the foot sole. The invention further includes a locomotion control system using one shock absorbing mechanism.

    摘要: A legged walking robot such as a two-legged walking robot has a plurality of movable legs and a plurality of foot soles mounted respectively on distal ends of the movable legs by respective foot joints. Each of the foot soles has a curved surface disposed on at least a portion of a peripheral edge thereof. The curved surface is shaped such that the foot joint follows a predetermined curved path along a forward direction in which the legged walking robot walks. The foot sole also includes at least one projection on one or each of leading and trailing ends of the foot sole in the forward direction. The projection is movable into and out of a projecting position from the foot sole, but is normally urged into the projecting position to support the foot sole stably on the terrain.

    摘要: In a legged mobile robot having at least a body and a plurality of legs each connected to the body through a first joint and a foot each connected to a distal end of each of the legs through a second joint, a floor reaction force detector is installed between the second joint and a contact end of the foot. More specifically, an upper portion of the floor reaction force detector is connected at a location near the second joint, and the contact end of the foot or thereabout is constituted by a spring mechanism that is lower in rigidity than a member constituting the second joint or thereabout such that a lower portion of the floor reaction force detector is connected to the contact end through the spring mechanism. With this, it becomes possible to provide the floor reaction force detector that can improve detection accuracy of the floor reaction force and prevent the performance of control from being degraded, while enabling to maintain a stable posture during standing and to decrease the impact at foot landing.

    摘要: It is arranged such that displacement sensors (70) are installed at a position in or vicinity of elastic members (382), to generate outputs indicating a displacement of the floor contact end of a foot (22) relative to a second joint (18, 20), and a floor reaction force acting on the foot is calculated based on the outputs of the displacement sensors by using a model describing a relationship between the displacement and stress generated in the elastic members in response to the displacement, thereby enabling to achieve accurate calculation of the floor reaction force and more stable walking of a legged mobile robot (1). Further, a dual sensory system is constituted by combining different types of detectors, thereby enabling to enhance the detection accuracy. Furthermore, since it self-diagnoses whether abnormality or degradation occurs in the displacement sensors etc. and performs temperature compensation without using a temperature sensor, the detection accuracy can be further enhanced.
