System description

SpiderCam architecture (Source: Benjamin Girault, DFKI)

The SpiderCam is a cable robot, which consists of a mount, 8 cables connected to 4 winches, and a controller. The winches cause the mount to fly through the Exploration Hall by increasing and decreasing the cable lengths. The mount is supplied with power and data transmission by cords inside the cables. The SC is controlled via CAN-Bus. It needs position changes as control input and delivers absolute positions based on the internal cable length measurement. The SC can load 150 kg of equipment. It is used in the project INVERITAS to simulate a service satellite.
