Linear electric actuator with a flexible hydraulic transmission

The technical capabilities of the transfer of mechanical energy between the different nodes are often limited. There are different mechanisms in which the working body is movable but the drive for constructional reasons must be stationary (e.g. hand devices, robotic joints, etc.). Alternative way to transfer of mechanical energy from the remote drive to the working body is the using of flexible shafts, cables, pneumatic and hydraulic machines, etc. This article describes a pilot version of an electrohydraulic linear drive with a flexible transmission.
