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.
