Rotating bearing support

 An important, easily underestimated detail in the design of the pikchain® is the interface between the c-chain® and the slewing ring, or the rotary union. The c-chain® must be secured in such a manner that it does not bend or collapse at the point of directional rotation. igus® has designed a special component to address this issue. On the one hand, it gently guides the energy chain in the radius, and on the other, facilitates nearly friction-free rotation by using a PRT bearing from igus®, without generating significant torque. A hollow shaft then connects the slewing ring or the rotary union with this rotating bearing support.

 As I already wrote in one of my earlier papers, the devil is truly in the details.

Teach-in arm on ADAM torso and repeatability

once again I want to link to Malte Ahlers homepage and 2 of his Videos from his robot project ADAM A1. Now he is really running the 5DOF arm and he is using the 2nd one as teach-in arm. The movement speed and reaction time between left and right arm really impress me!

Serviceroboter “Hobbit” (TU Vienna) Project with robolink® arm

The Vision4Robotics Group at Vienna University of Technology (Team Dr. Walter Wohlkinger) is leading the project “Hobbit” in cooperation with our customer Hella Automation in Austria. Stefan Hofmann has equipped the robot with a robolink® joint arm (5DOF with angle sensors) and a FESTO adaptive gripper. They are using their own motors for the actuation. Here are the first test results on youtube:

robolink® angle Sensors (general description and technical details)

First of all I want to thank all robolink® users and customers for interesting projects in 2012 and wish you all a happy and exciting new year 2013. The last year brought us projects from USA, China, India, Japan, Austria, France, Slovenia, Turkey, Macedonia, Italy, England, Switzerland, Poland, Brazil, Great Britain, and the Netherlands (besides Germany). The applications are very wide spread over medical and industrial applications as well as camera or sensor positioning, universities or research and development.

Today I would like to share 2 very nice links from Malte Ahlers (our beta tester since 2010) who explains very nicly the function of our angle sensors and how the signals from the angle encoder are working. This is written in German.
