Automation made easy with new modular motion concept from igus

The Apiro mission: Performance of complicated movements – like those of a spider – with only three new worm gears for standard, linear and inverted motion

The pressure of competition on companies is growing locally and globally due to the increasing automation of production processes. Now, in order to make automatic processes possible cost-effectively and individually, igus is developing low-cost solutions with the help of high-performance plastics such as the new modular motion system, robolink Apiro.

Design engineers can choose from three lubrication-free worm gears for standard movement, inverted movement and linear movement. For the user, there are practically no limits, with solutions ranging from the simple linear robot to complex humanoid and animatronic robots.

Implementing individual automation solutions easily and cost-effectively is the mission of the new robolink, the Apiro modular motion system from igus.

When in development, the focus was on decoupling the motor and gearbox as well as introducing completely new kinds of worm gear to achieve a number of axes for a particular robot.

Gearboxes with linear motions, and inverted and conventional robolink worm gears in four different sizes were planned and, thanks to the exceptional modularity of the system, can be combined with each other as required.

Therefore, with the new modular system, even complicated movements can be implemented, sich as individual SCARA robots and linear robots. Transport and handling systems, as well as humanoid and animatronic robots, which can perform movements like those of a spider, can also be implemented. The new robolink series is also suitable for training, development and research as different kinematics can be set up easily and quickly.


Flexible design due to modular system and multi-functional profile

With the new Apiro series, high-quality tribo-polymers with solid lubricants are used. The corrosion-free and chemical-resistant high-performance plastics ensure a high degree of stability, low weight, a long service life and freedom from the need for maintenance.

In the case of the modular robolink Apiro system, the joints are pieced together with a multi-functional profile made of aluminium, making it possible to insert drive shafts through a hollow space in the middle. The gearbox causes the aluminium profile to rotate, and as a result, it is ideally suited for use in robotics and rotating applications.

In the case of the new worm gear with linear movements, the aluminium profile can travel linearly through the worm gear or the worm gear travels on the linear profile, and also enables the user to connect the different gearboxes of the robolink Apiro series.

Placing several Apiro joints side by side makes parallel joint connections possible as well. This results in innumerable possibilities of combination in order to automate very different applications.
