Abstract

A robot is provided with a robot weight compensation device having at least one hose element including an internally pressurized gas-tight inner hose portion cooperating with a high tensile strength outer portion. The high tensile strength outer portion includes non-elongatable fibers oriented relative to an axis of the at least one hose element by an angle not equal to 0° and 90°. An outer flexible protective jacket covers the fibers. A first fixing element is fixed to a first end of the hose element. The fixing element is connected to a first part of the robot. A second fixing element is fixed to a second end of the hose element. The second fixing element is articulated to a second part of the robot being movable relatively to the first robot element.
