UTact: Underwater Vision‐Based Tactile Sensor with Geometry Reconstruction and Contact Force Estimation

Advanced Robotics Research, EarlyView.
Embedded flexible sensing technologies advance underwater soft robotics, yet most systems still suffer from hysteresis and limited perceptiveness. Instead, vision‐based tactile sensors provide reliable and rapid feedback essential for complex underwater tasks.

Analysis of One-Way and Two-Way Relay Networks Affected by Hardware Impairments

, 2018
Physical transceivers have impaired hardware which creates distortions that degrade the performance of the communication system. The majority of contributions in the technical area of relaying ignore hardware impairments and assume that the hardware is ...

Achievable Rate of Rician Large-Scale MIMO Channels with Transceiver Hardware Impairments

, 2020
-Transceiver hardware impairments (e.g., phase noise, in-phase/quadrature-phase (I/Q) imbalance, amplifier nonlinearities, and quantization errors) have obvious degradation effects on the performance of wireless communications.

Echinoderm‐Inspired Autonomy for Soft‐Legged Robots

Advanced Robotics Research, EarlyView.
Inspired by echinoderms, a modular soft robot achieves autonomous phototaxis without a central controller or explicit communication. Each limb independently adapts its actuation timing through local sensing and short‐term memory. Coordination emerges purely from physical interactions, demonstrating resilience to changes in morphology, environment, and ...

Auditory–Tactile Congruence for Synthesis of Adaptive Pain Expressions in RoboPatients

Advanced Robotics Research, EarlyView.
In this work, we explore auditory–tactile congruence for synthesizing adaptive vocal pain expressions in robopatients. Using a robopatient platform that integrates vocal pain sounds with palpation forces, we conducted 7680 trials across 20 participants.

Hardware-Aware Joint Localization-Synchronization and Tracking Using Reconfigurable Intelligent Surfaces in 5G and Beyond

IEEE Open Journal of the Communications Society
This work investigates joint localization-synchronization and tracking in 5G and beyond. In particular, we target realistic circumstances where the theoretical assumptions of a perfect synchronous system and ideal transceivers no longer exist.

A State‐Adaptive Koopman Control Framework for Real‐Time Deformable Tool Manipulation in Robotic Environmental Swabbing

Advanced Robotics Research, EarlyView.
This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.
