Abstract: The invention relates to a humanoid robot comprising two elements connected by a spherical joint with three degrees of freedom in rotation, the joint being moved by three actuators each acting in one of the three degrees of freedom. The invention is of particular use in the production of humanoid robots coming as close as possible to the human anatomy. According to the invention, the first and the second of the actuators act in parallel and the third of the actuators acts in series with the first and the second of the actuators.

Abstract: A humanoid robot includes a spherical joint with three degrees of freedom in rotation about three axes, the spherical joint connecting a first element and a second element of the robot, and three actuators for moving the spherical joint. The three actuators include a first actuator coupled to the first element, a second actuator coupled to the second element and the first actuator, and a third actuator coupled to the second element and the first actuator. The second actuator and the third actuator act in parallel and coupled together. The first actuator acts in series with the second actuator and the third actuator about a first axis of the three axes. An angular range of movement about the first axis is greater than an angular range of movement about either a second axis or a third axis of the three axes.

Abstract: A converter for converting mechanical energy into hydraulic energy and a robot implementing the converter are disclosed. The converter includes a shaft rotated about a first axis relative to a casing, a hub defining a bore about a second axis, the shaft rotating in the bore. The first axis is parallel to the second axis, and a distance between the first axis and second axis defines an eccentricity. At least two pistons are movably disposed in radial housings of the shaft with the at least two pistons bearing against the bore. Movement of the pistons feed a hydraulic fluid into one of two annular grooves of the casing arranged in an arc of a circle about the first axis, and the hub is configured to translate along a third axis to modify the value of the eccentricity between two extreme values.
