As part of a study project at the HAW Hamburg, a robot was built with parallel kinematics. The passive arms of the Delta robot are implemented using the igubal® variable double spherical bearings "KDGM-08-700-A-J. Because of the individual pitch sizes in small quantities and a large tilt angle (spherical ball to housing), the igubal® double spherical bearings fit perfectly with this task.
Other benefits include lighter weight, high mechanical stability and zero backlash of the spherical ball in the housing. Upon successful completion of the construction phase by Mr. Habermann, the Delta robot was sent to a masters student, who dealt exclusively with the control of the robot.
