Development of a ball gripper

Task:

Reduction of the friction when a camera arm is extended.

Longer grip with lubricant-free polymer bearings from igus®

Martin Karwowski and Dominik Böhme developed the ball gripper in the scope of a project work for the Fraunhofer Institute for autonomous intelligent systems. The goal was to reduce the friction when the robotic arm is extended. The problem could be solved, the technical performance improved, the friction lowered and the service life extended by the use of igus® polymer bearings.

"An essential advantage compared to the traditional metal bearings is that the polymer bearings can operate without lubricants. Thus the regular maintenance can be avoided. Moreover, polymer bearings are cheaper to purchase and they even increase the cycle rate of the machine," says Martin Karwowski.

The detailed view shows the working of iglidur® bearings, which are insensitive to dirt, corrosion resistant and vibration dampening.

 

The camera arm of the robot can be intensively utilized with the aid of the polymer bearings. Low friction and maintenance free
