Hardware module for a robotic system, and mechanical coupling

A Hardware Module for a robotic system, the Hardware Module comprising two mechanical links connected by a rotary joint and a flexible conduit,

• and a cylindrical conduit guiding space defined by a hollow space between an inner cylinder wall and an outer cylinder wall, the two cylinder walls extending from a first end to a second end of the hollow space and being coaxial with one another and with the axis of the rotary joint,
• the conduit being at a first end attached to the first link and guided from there into the hollow space at the first end of the hollow space, and
• the conduit being at a second end attached to the second link and guided from there into the hollow space at the second end of the hollow space,
• the length of the conduit between the first end and the second end allowing for a relative rotation of at least 180° or at least 270° or at least 360° between the first link and the second link,
• wherein a channel leads from the first link to the second link and runs in a region of the rotary joint coaxially to the axis of the rotary joint, wherein the channel comprises two tube sections sliding in one another with a fluid-tight connection.
