As part of a study project at HAW Hamburg, a robot with parallel kinematics was constructed. The passive arms of the delta robot are implemented with the igubal® variable double joint. The igubal® double joints are ideally suited for this task due to the individual inside micrometers for small quantities and a large tilt angle (spherical ball against housing).
Further advantages are the weight saving, the high mechanical strength and the absence of clearance of the spherical ball in the housing. After successful completion of Mr. Habermann's design phase, the delta robot was passed on to a master student, who finally dealt with the control of the robot.
