igus UK has developed robolink, a
multi-axis joint for humanoid robots
and lightweight automation tasks. A
modular system, robolink combines
design freedom with simplicity and is
well-suited where masses are to be
kept as low as possible. At the heart of
the modular system are lightweight,
maintenance and corrosion-free joints
with tribologically optimised plastic
bearings that are driven via cables and
can rotate and swivel freely.

To articulate the multi-axis joints,
igus has developed a range of flexible
Bowden cables with high-performance
polymer jackets that combine low
friction values with a long service life.

igus Bowden cables have extremely
small bending radii, making highly
flexible movements possible.
