STEP data for robolink D

since October 2015, the standard version of RL-D-50 (-101 and -102) is also available from stock. The missing PRT-02-50 version was the reason for the delay. Please find attached here the STEP data for our joints for all variants and sizes, as well as for a collection of motor kits (with igus stepper motors).

These STEP data will soon be available via our main igus download center too! It is only a question of a few more days……

robolink at MOTEK, 4 DOF, new documents

At this year’s MOTEK show in Stuttgart (GER) we will show the possibility to build 4 DOF robot arms with our motorized joints. 2 films at the end of this entry show 2 possible concepts:

1) “small” version with 4 joints size 30 – 30 -20 – 20, built with igus DC motors. No programming possible, just a joystick control.

2) “big” version with 4 joints size 50 – 50 – 30 – 20, built with igus stepper motors and a robolink gripper.

Please be aware that both arms are no sales products. They are examples of how a joint arm could look like. The connection parts are made of folded metal sheet parts. Please contact me for further questions in this issue (mraak@igus.de).

Also attached our new catalogue (this version in GER with more RL-D infos and german list prices). Eng. version will follow soon.

And additionally 2 updated versions of tech. data sheets for symmetrical joints (version 101 with 2 PRT) and asymmetrical joints (version 102 with 1 PRT)

robot FLASH from Wroclaw University of technology (Poland)

The team of Jan Kedzierski (Ph.D.) from Wroclaw University of technology now presents their NEW generation of the autonomous robot FLASH. It is (again) equipped with 2 pcs. 5 DOF robolink wire driven joint arms. They developpped their own drive technology for this robot based on DC/BLDC motors as an open source project. It will be published soon, I will link to their project then.

Ini switch for robolink D

We control the position of our RL-D joints by using the motor encoder (of our igus stepper motors). In order to define a reference point (or ZERO position), an additional inductive initiator switch (=Ini) can be installed on the joint as an option. The spec. of the Ini switch is given below, it is the same part that igus uses for drylin products. The inductive swich needs a steel part as trigger, we install a set pin in the moving part of our PRT inner ring.

The installation finally looks like this:
