| 20110085922 | Converter for Converting Mechanical Energy Into Hydraulic Energy and Robot Implementing Said Converter - The invention relates to a converter for converting mechanical energy into hydraulic energy and to a robot implementing said converter. The invention can particularly be used in the production of humanoid robots in which autonomy is to be improved. The converter includes a shaft rotated by mechanical energy about a first axis relative to a casing, a hub comprising a bore formed about a second axis, the shaft rotating in the bore, the two axes being parallel and a distance between the axes forming an excentricity, at least two pistons capable of movement in a radial housing of the shaft, the piston bearing against the bore. According to the invention, the movement of the piston feeds a hydraulic fluid into two annular grooves of the casing arranged in an arc of a circle about the first axis, the hydraulic energy being generated by a pressure difference of the fluid present between the two grooves, and the hub is capable of translation along a third axis perpendicular to the first two axes in order to modify the value of the excentricity between two extreme values, one being positive and the other being negative, so as to generate an inversion of the fluid pressures in the grooves, thereby reversing the inlet and discharge roles of these grooves while maintaining the same rotation direction for the shaft. | 04-14-2011 |
| 20110147103 | HUMANOID ROBOT IMPLEMENTING A BALL AND SOCKET JOINT - 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. | 06-23-2011 |
| 20110185837 | HUMANOID ROBOT IMPLEMENTING A SPHERICAL HINGE WITH COUPLED ACTUATORS - The invention relates to a humanoid robot using a spherical joint with coupled actuators and a method using the spherical articulation. The invention is of particular utility in the production of humanoid robots coming closest to human anthropomorphism. The joint connects two elements of the robot. The joint is moved by three actuators of which a first joint and a second joint act in parallel and are coupled together, and of which a third actuator acts in series with the first two actuators about an axis. According to the invention, the axis of the third actuator is the axis of which the angular range of movement must be the greatest in order to come close to human anthropomorphism. | 08-04-2011 |
| 20110186362 | FOOT FOR HUMANOID ROBOT - The invention relates to a foot and a humanoid robot having the foot. The invention is of particular utility in the production of humanoid robots coming as close as possible to the human morphology. According to the invention, the foot includes: a sole, toes, a motorized connection, independent of the ankle, in rotation between the sole and the toes, the toes being able to move on an angular travel about an axis of the connection, an actuator allowing the connection to be motorized, and means for controlling the actuator in a standalone manner. | 08-04-2011 |
| 20110247446 | Hexapod Platform and Jack That Can be Used in the Hexapod Platform - A hexapod platform and a jack that can be used in the hexapod platform are provided. The jack includes a body, a piston capable of translational movement with respect to the body and a rod connected to the piston to follow its translational movement and by means of which the jack applies load. The rod is connected to the piston by means of a ball joint. The hexapod platform comprises six jacks according to the invention. | 10-13-2011 |
