Optical Wireless Communications with Metasurfaces: Current Status and Potential for Intelligent Communications

open access: yesAdvanced Photonics Research, EarlyView.
Optical wireless communications (OWCs) provide a promising alternative to spectrum‐congested microwave wireless communications. Recently, the use of metasurfaces with sub‐wavelength features for dynamic beam steering, beam manipulation, and spatial or optical‐angular‐momentum mode generation, conversion, and multiplexing in OWCs is proposed and ...

A Quadruped Piezoelectric Ultrasonic Actuating Robot with Foot‐Leg‐Trunk‐Integrated Structure

open access: yesAdvanced Robotics Research, EarlyView.
This study proposes a novel foot‐leg‐trunk‐integrated quadruped piezoelectric ultrasonic actuating robot with small size and lightweight. A hybrid vibration mode combining the first‐order out‐of‐plane bending vibration of the trunk and the first‐order horizontal bending vibration of driving legs is designed to generate elliptical trajectories at foot ...

A Low‐Cost Curvature Detection Method for an Untethered Biped Pipeline Climbing Robot with Energy‐Efficient Strategy

open access: yesAdvanced Robotics Research, EarlyView.
A low‐cost pipeline curvature detection method has been proposed for an untethered biped pipeline surface climbing robot (BPCR) system with a five‐degree‐of freedom structure. The BPCR features adaptive vacuum suction cups equipped with multiple laser sensors on the suction modules to detect the curvature of various surfaces.
