Cost-effective automation modular kit for maximum flexibility

With the robolink® Apiro modular system, low cost automation achieves a new level of modularity - Made in Germany.

As competition between manufacturers increases, both locally and globally, more manufacturing processes are being automated. Korea's level of automation is eight times higher than the global average. China recorded the world's most rapid adoption rate in 2017 and plans to intensify automation by 2020. Germany ranks first in Europe. No reason to relax because the competition never sleeps.

To enable cost-effective and fully-customised automation, igus® develops low cost automation systems, such as the world's first robolink® Apiro. The name says it all: Apiro is derived from the Greek word for "unlimited". With countless possible combinations of components, individual solutions, from simple linear robots to complex humanoid robots, can be implemented according to your individual requirements.

All the advantages at a glance

  • Automate cost-effectively and individually with innumerable possibilities of combination
  • different kinematics: worm gear with conventional, inverted linear motion
  • 6 DOF* can also be designed
  • Modules can be switched consecutively, side by side
  • Considerably reduced cabling time and effort
  • Construction of SCARA and articulated robots as well as linear robots up to complex humanoid robots possible
  • Self-lubricating, dirt-resistant gearbox
  • Light weight
  • Lubrication-free
  • Cost-effective
  • Low clearance
  • Long service life





Everything from one manufacturer: Automate quickly and easily!

When the robolink® Apiro modular kit was being developed, the focus was on decoupling the motor and gearbox as well as on the introduction of completely new kinds of worm gears. The result: The path to customised automation solutions becomes extremely simple and short. No more need to search for everything from different manufacturers, because you get electrical and, above all, mechanical components for cost-effective automation at igus®. Gearbox with linear motion, inverted and conventional robolink® gearbox in four different sizes are planned and, thanks to the exceptional modularity of the system, can be combined with each other as required.

Maintenance intervals can be extended:
All worm gears in the Apiro series use high-quality igus® tribo-polymers with dry lubricants that eliminate the need for additional lubricants. The high freedom of movement of the Apiro modular system is made possible by the different types of gearboxes. The simple worm gear is extremely light compared to standard worm gears. With the inverted worm gear, the continuous multifunction profile rotates, making it ideal for robotics and rotary applications. In the gearbox with linear motion, the multifunction profile can be moved linearly through the gearbox or the gearbox moves on the profile.

Different installation sizes

Gearboxes in four installation sizes: 12, 20, 30 and 50

Decoupling of motors and joints simplifies the cabling of the axes

Suitable for force ranges from about 2.5 Nm to 40 Nm

Connection options for igus® DC and stepper motors and other common drives

Apiro joints connected in parallel and in series  
How can Apiro joints be combined?

In the case of the modular robolink® Apiro® system, the joints are joined together by means of a multi-functional profile made of aluminium. This makes it possible to insert drive shafts through a hollow space in the middle. The multifunction profile of the robolink® Apiro® series, for example, allows serial connection of gearboxes. Placing several Apiro® joints side by side makes parallel joint connections possible as well.
Typical areas of application:

  • Linear robots
  • Humanoid systems
  • Angular gearbox
  • Undercarriages
  • Rotary-drive unit

Animatronic Apiro construction in spider shape  
What can be constructed with robolink® Apiro?

With Apiro, for example, the following solutions can be built:

Linear robots

SCARA manipulators

Sprue picker, e.g. for the removal of products from injection moulding machines

Systems for camera positioning

Transport and handling systems

Animatronic or humanoid inspired robots that mimic, for example, movements of a spider
