robolink® NEWS for MOTEK show

At the MOTEK show in Stuttgart (GER), we will present the following MAIN news for robolink:

Our current 4 DOF joint kit system will be enlarged by a fifth axis (“hand rotation”). This will be achieved with our NEW strain wave gear box RL-S-17 in combination with an igus NEMA11 stepper motor. From next week on we will be able to offer and suplly 5 DOF joint arms with our lightweight, lubrication free joint system. Please find attached our latest NEWS brochure (as pdf) with latest news on page 8, 14-15 and 22-23.

Also attached 3D STEP data for our small and big version 5 DOF joint arms as well as drawings with part lists.

The picture shows our 5th axis that can directly be mounted to our RL-D-20-101 joint (usually used as 4th axis in our arms). Datasheet for this unit attached as PDF.

This video from CEMAT fair in GER shows our idea of low cost automation perfectly.

Our customer EPS Gmbh has designed an “automatic book scanner” with a 3 DOF robolink joint arm. Our arm has been designed individually for thi task and it can handle different book sizes. For requests about the product, please contact :

Company Djukic Software GmbH in Nürnberg (GER) has developped a software for easy programming of individual joint arms.

The video shows first results for our RL-D 4 DOF joint arm (RL-D-RBT-3322-AC). It shows the easy use of “inverse kinematics” in this case (programming of xyz movements for a robotic arm).
