| Riassunto: | This article presents a gyroscopic mechatronic system, which helps the laparoscopic surgeon to wirelessly control the zoom and panoramic position of a camera and a light source, adapted to a manipulator for minimally invasive surgery. The gyroscope adapted to the manipulator generates a reference signal used by an open loop control. The camera and light source system are mounted on an electromechanical device (robotic arm) with three degrees of freedom (3DOF). Experiments performed with the system show good pan, tilt and zoom performance of the camera and light source. Success is measured by comparing an input signal from the voltage levels generated by a transducer with micro-electro-mechanical systems (MEMS), versus the signals for the angular positions of two servo-motors (pan and tilt) and zooming in or out of the camera by a DC motor. |
