Abstract: This paper presents a piezoelectric tube scanner with a novel electrode pattern and describes how it may be used for simultaneous sensing and actuation. The electrodes are arranged such that the tube is driven in an antisymmetrical manner, resulting in a collocated system suitable for positive position feedback (PPF). A PPF controller is designed to d the scanner’s resonance. Piezoelectric strain-induced voltage is used as measurement. The device is then installed into an atomic force microscope to obtain open- and closed-loop images of a grating at 10, 15.6, and 31 Hz scan rates. The closed-loop images are noticeably superior to the open-loop images, illustrating the effectiveness of the proposed scanner when used simultaneously as a sensor and an actuator.

Abstract: Understanding the terrain in the upcoming path of a ground robot is one of the most challenging problems in field robotics. Terrain and traversability analysis is a multidisciplinary field combining robotics with image and signal processing, feature extraction, machine learning, three-dimensional (3D) mapping, and 3D geometry. Application scenarios range from autonomous vehicles on urban networks to agriculture, defence, exploration, mining, and search and rescue. Given the broad set of techniques available and the fast progress in this area, in this paper we organize and survey the corresponding literature, define unambiguous key terms, and discuss links among fundamental building blocks ranging from terrain classification to traversability regression. The advantages and the drawbacks of the methods are critically discussed, providing a comprehensive coverage of key aspects, including open code, available datasets for experimentation and comparisons, and important open research issues.
