Abstract
An electromagnetic system is provided for accurately sensing and remotely controlling a tool-to-workpiece spatial relationship. A typical application of the system may include a saw being sensor controlled through the process of removing a reinforced concrete covering from and about an underwater pipe or other metallic object that must be protected.
