how to change worm wheels (video)

the main differences between our gears and standard metal gears are:

ours are lubrication free (no grease, no oil) and very lightweight due to plastic and aluminium parts instead of steel, brass or bronze (=standard design). The same is valid for the bearings we use on the output (igus PRT = polymer round tables).

This makes it very easy to open our joints, in case worm wheels need to be exchanged (reasons for exchange might be: broken gear teeth due to overload on the output or the need to change gear parts due to changing conditions like temperature,…). The video shows how to proceed:

 

COMPAMED 2014, robolink in wheel-chair application

At this year’s COMPAMED, we will show a 4 DOF robolink Joint arm, mounted on a common wheel chair. igus does not offer this as a complete solution for end users, but we want to demonstrate the possibility to use our Joints and actuators for such interactive purposes. This Joint arm may perform pre programmed movements as well as individual movements controled by common Joysticks. The gripper is an igus 3 jaws gripper. Please visit us at the COMPAMED in Düsseldorf (12.11.-14.11.14) at hall 8b / A20.

NEW control solution by WAGO

At the SPS trade show in Nürnberg/Germany we will present and demonstrate a new control solution. More informations as well as budget prices will be announced in 2-3 weeks. This modular control concept can be used as well with the classic, wire driven joints as with the new robolink D joints

 

In cooperation with WAGO Kontakttechnik GmbH & Co.KG, a Germany-based manufacturer of automation and interconnection products, a solution for controlling the robolink components with regard to industrial requirements is available. The modular WAGO-I/O-SYSTEM 750 is used stand alone for a direct control of the stepper drives using the encoder feedback from the robolink axis. The application engineer may choose between either using the well-known CODESYS programming languages standardized in IEC61131-3 or a free programming in Linux, which is used as operating system on WAGO’s PFC200 controller.

The ready-made libraries and application notes provided by WAGO ensure an easy start-up in CODESYS. Thus a user-specific solution for robolink applications is only a small step away. Due to the possibility of a seamless integration of the IME software any application may be realized with minimum engineering efforts.

The WAGO-I/O-SYSTEM can be adapted regarding to the individual requirements in a modular thus flexible way. For control of the robolink system a programmable controller PFC200 (Art.-No. 750-8202) and additional for each of the joints a stepper controller (max. 70V / 7,5A; Art.-No. 750-672) and an incremental encoder interface (Art.-No. 750-631/000-010) are mandatory.

 

robolink as camera crane

Our customer “Kuno Seebaß Medienproduktion” in Germany was one of our earlier beta testers. He built this nice camera crane with our joints. His aim is to optimize it now with more igus components. I like the video because it shows nicely our possibilities with robolink in these applications.
