摘要:
A legged walking robot such as a two-legged walking robot, for example, has an articulated structure with at least two degrees of freedom, one of which is a degree of freedom for angularly moving a leg in a pitch direction about a first axis of a hip joint assembly, comprising an electric motor for angularly moving the leg in the pitch direction. The electric motor has an output shaft which is axially aligned with the first axis about which the leg is angularly movable in the pitch direction. The articulated structure also has a speed reducer having an input shaft which coaxial with the output shaft of the electric motor. The other degree of freedom is a degree of freedom for angularly moving the leg in a roll direction normal to the pitch direction. The articulated structure also includes a second electric motor for angularly moving the leg in the roll direction and a second speed reducer having an output shaft which is coaxial with a second axis about which the leg is angularly movable in the roll direction.

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. A plurality of pipes are positioned in the arms, respectively, for supplying a fluid under pressure to the articulations, and a plurality of oil passages are disposed in the articulations, respectively, and branched from the pipes, respectively, to supply the fluid under pressure to the fluid pressure motors.

Provided is an arm structure for a robot which can favorably carry out jobs which are typically performed by humans. By determining the length of the arm and the height of the axis of rotation of the arm in such a manner that a range of rotational motion of the arm in accessing the region can be covered by a range in which the fore-and-aft distance to the tip of the arm can be linearly approximated, even though the trajectory of the arm is approximated by a line, the error in the distance to the object can be limited within a prescribed range, and the practicality and economy of computation can be achieved at the same time.

A resource management device includes an application processor and a media processor. The media processor includes function modules, each of which has a basic function and an extended function, a congestion analysis section, a database section and a system management section. If a congestion is detected in response to a function addition request from the user, the congestion analysis section selects an extended function to be deleted, deletes the selected extended function, and then adds the function being requested. Thus, resources can be assigned preferentially to basic functions while releasing resources allocated for extended functions as necessary, thereby efficiently utilizing the resources.

A robot arm which allows the two hands to be brought together in front of the chest. In a robot arm comprising a shoulder joint attached to a body so as to be rotatable around a laterally extending axial line, an upper arm attached to the shoulder joint so as to be rotatable around an axial line perpendicular to the laterally extending axial line, a forearm attached to the upper arm via an elbow joint, and a hand attached to a free end of the forearm, the elbow joint is attached to the upper arm so as to be rotatable around a longitudinal axial line of the upper arm.

A liquid inlet located in the lower position of a liquid passage is sealed with the valve guide of a valve body. The lever pushes the valve guide of the valve body to open up the liquid inlet. A pair of fixing arms is provided on the edge of the lever. An insertion hole of the pivot installed in a protruding manner or two sidewalls of the liquid passage is formed on each fixing arm. When moving the lever in the direction opposite to operation around each fixing arm, the boss member is abutted on sidewalls to widen the gap between each fixing arm to remove the insertion hole from the pivot. This makes it easy to take apart and assemble the structured parts of the plug and makes it washable in every nook and corner inside the plug structure.

A method for driving an actuator for displacing a mechanism connected thereto to a target displacement and holding it there against static load, wherein the internal friction force is utilized for holding the displacement, thereby reducing the actuator load and energy consumption. Command value of the actuator is once directed above the target displacement with respect to the direction of gravity so as to cause the internal friction force to act in the direction opposite to the static load. For that purpose, the command value is varied by adding a bias or by changing a gain to be multiplied thereto.

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.
