摘要： An armature winding structure for use in an electric motor includes a web-shaped strand bundle composed of a plurality of parallel strands. The strand bundle has a plurality of longitudinally spaced bends and a plurality of straight strand bundle segments. Adjacent ones of the strand bundle segments are positioned one on each side of one of the bends. The strand bundle segments are transversely staggered on one side of the strand bundle successively from one end to the other of the strand bundle, by intervals each substantially equal to the width of the strand bundle. The strand bundle segments thus staggered are longitudinally folded over along fold lines extending respectively across or near the bends transversely of the strand bundle, thereby providing a plate-like winding in which the strand bundle segments lie adjacent to one another.

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： An articulated mechanism for use as an articulated arm of an industrial robot, for example, includes a plurality of arms interconnecting articulations having respective fluid pressure angular displacement motors for angularly displacing the arms relatively to each other. The motors have sidewalls forming working chambers, where an inner surface of the sidewall is exposed to working fluid pressure tending to bow the sidewall outward, and an outer surface of the sidewall has a plurality of counteracting pressure chambers which apply a counteracting pressure force against the sidewall to oppose the outward bowing force, the counteracting pressure force increasing in pressure surface area as the piston is displaced within the motor chamber.

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： A biped walking robot and system for controlling the robot. The system provides smooth posture control by eliminating interference arising between the frictional force of the ground acting on the legs of the robot and the driving force of the leg joints. A six-dimensional force and torque sensor is provided to detect six force or moment components and based thereon, an angular command to joint motors is corrected. A joint structure of the robot is described, wherein the axes of the drive joints are arranged at right-angles to one another to thereby enable accurate positional control to be effected using Cartesian coordinates.

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 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.
