The use of cable manipulators, which are basically versatile and reconfigurable systems, brings about some issues limiting its deployment in industry. The patented device has been designed so that its control is as simple as possible to make it appealing for a large number of application fields.
More specifically, the system consists of a flat rectangular workspace varying in shape and size depending on assembly. Similarly to most cable robots, it is actuated by winches, while being equipped with force sensors. Its end-effector can reach high accelerations and, by varying the type of laser head on it, the robot is able to perform very different tasks.


  • Surfaces’ marking and decoration (e.g.wood, cardboard, marble, leather);
  • Restoration operations;
  • Welding;
  • Thermal treatments;
  • Inspection by cameras.


  • High precision in wide surfaces treatment;
  • Directions free cables;
  • Economic and energy savings when deploying the device;
  • Easy transportation and configurability on site.
