1. In a control system for a tool-positioning robot,a work-sensing probe that senses the locus of work to be performed, including the loci of a continuum of such work, without physically contacting the work, comprisingmeans for generating a focused shockwave,means for receiving the reflection of a focused shockwave,means for differentiating the time/pressure parameters of the original shockwave from those of its reflection,and means for translating the observed parametric differences into an electric signal within the control system to direct the robot to position the tool at the sensed locus of the work.
