robolink hand system

The robolink® hand system has five movable axes, whereof four axes are implemented by two robolink® multiple-axis joints (two axes per joint). An igus® PRT-02-30-AL slewing ring bearing forms the fifth axis. The slewing ring bearing provides for the rotation of the entire arm (max. 150°, as otherwise an excessive twisting of the drive ropes is caused), which is manually implemented by an SLS-manufactured handle. The axes of the two robolink multi-axis joints are controlled by four hand wheels. In the hand system a total of 8 ropes are installed, two for each degree of freedom of a joint. The ropes are wound on plastic spindles (SLS components). The spindles are in turn mounted on shafts which are driven manually directly by the aforementioned hand wheels. The gripper is a separate development, also made in the SLS process, and is pneumatically controlled by a foot pedal. The entire structure was built in a frame of aluminum profiles.
