A novel cable-based metrology system is presented wherein six cables are connected in parallel from ground-mounted string pots to the moving object of interest. Cartesian pose can be determined for feedback control and other purposes by reading the lengths of the six cables via the string pots and using closed-form forward pose kinematics. This paper focuses on a sculpting metrology tool, assisting a human artist in generating a piece from a computer model, but applications exist in manufacturing, rapid prototyping, robotics, and automated construction. The proposed real-time cable-based metrology system is less complex and more economical than existing commercial Cartesian metrology technologies.
