摘要：

Robotic platforms created to place devices or sensors at specific coordinates, are efficient systems for automation of positioning tasks when taking actions on or acquiring signals from an exact point, are needed. In that sense, the methodology of the design and implementation of a mechatronic platform to position an ultrasonic transducer over an inspection grid, in automatically or remote manual way, is described through this article. The reason for robotic positioning of this transducer is to acquire ultrasonic signals coming from a piece which is wanted to be evaluated, containing information form that piece. The designed system is able to ensure a mean uncertainty in the position measurement around 1.1% and 2% on axis X and Y, and to save the digitized ultrasonic signals in an electronic sheet.
