摘要： In a legged mobile robot (1), each leg (2) has at least a first joint (16) and a second joint (18, 20) located below the first joint in the gravitational direction, and the actuator that drives the second joint (54, 56) is located at least one of a position same as that of the first joint and a position (28) above the first joint in the gravitational direction. With this, it becomes possible to lighten the weight of the ground-contacting ends of the legs and thereby provide a legged mobile robot enabling reduction of the inertial forces occurring in the legs during moving, particularly during high-speed moving.

摘要： 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. An impact load during the landing of the leg of the legged mobile robot may smoothly be reduced in a light-weight configuration.

摘要： A landing shock absorbing device 18 provided in a foot mechanism 6 of a leg of a robot comprises an inflatable and compressible bag-like member 19 (a variable capacity element) on a bottom face side of the foot mechanism 6. The bag-like member 19 is constructed of an elastic material such as rubber. Air in the atmosphere can flow into and out of the bag-like member 19 by inflow/outflow means 20 provided with a solenoid valve 27 and the like. In a landing state of the foot mechanism 6 and in a state immediately after the foot mechanism shifts from the landing state to a lifting state, the solenoid valve 27 is closed to maintain the bag-like member 19 in a compressed state. Furthermore, during the bag-like member 19 in the inflating state during the lifting state of the foot mechanism 6, by controlling timing when the solenoid valve 27 is switched from a valve opening state to a valve closing state, a height of the bag-like member 19 in a compression direction is controlled to be a height suitable for a gait type of the robot. Thereby, posture stability of the robot can be secured easily while reducing a impact load in the landing motion of the leg of the legged mobile robot, and further, a lightweight configuration can be achieved.

摘要： An assist device that applies an auxiliary driving force to a joint in parallel with a driving force of a joint actuator between a thigh portion and a crus portion, which are a pair of link members of a leg. The assist device generates the auxiliary driving force by use of spring device, such as a solid spring or an air spring. A member supporting a rod member connected to the spring device is provided with a device for transmitting a bending and stretching motion of the leg at the joint (a relative displacement motion between the thigh portion and the crus portion) to the spring device to generate an elastic force of the spring device, and for discontinuing the transmission of the bending and stretching motion to the spring device. This transmitting device is controlled in accordance with a gait of a robot. Thus, a burden on the joint actuator is reduced where necessary and favorable utilization efficiency of energy can be stably ensured.

摘要： An assist device is provided with a spring device that generates an auxiliary driving force, by an elastic energy, acting on a joint of a leg. The spring device includes a gas spring having a cylinder and a piston. Bending/stretching motion between link members and at the joint is transmitted to the spring device through a motion transmission device that includes a link arm. The spring device is provided so that the auxiliary driving force increases as a knee bending angle θ increases until the knee bending angle θ reaches a predetermined angle, and so that, once the knee bending angle θ exceeds the predetermined angle, the auxiliary driving force becomes smaller than or equal to the driving force obtaining at the predetermined angle, effectively reducing a burden on an actuator of the legged mobile robot joint.

摘要： 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. An impact load during the landing of the leg of the legged mobile robot may smoothly be reduced in a light-weight configuration.
