Multichannel airborne ultrasonic ranging system based on the Piccolo C2000 MCU

Abstract

The combination of different characteristics of airborne ultrasonic transducers for ranging applications opens up new applications for autonomous navigation systems in robotics. The features of a Piccolo C2000 MCU are suitable for the design of a ranging system with four channels. Each channel has different operating range and accuracy depending on the transducer characteristics and the implemented ranging technique. This paper presents the system architecture and the experimental results obtained with transducers operating at 40kHz, 100kHz and 300kHz.
