Push the Limits: Human‐Like Multimodal Extreme Embodied Intelligence for Autonomous Racing

open access: yesAdvanced Robotics Research, EarlyView.
Autonomous racing tests embodied intelligence under extreme control limits of speed, actuation, and decision‐making. Inspired by human multimodality, we present Apex, an embodied agent deployed on a super‐formula racing car at Yas Marina. Integrating physics‐informed perception, multimodal learning, and tasking, Apex cuts lap times by 15% and achieves ...

A Spectral Entropy-Based Metric for Evaluating Speech Perceptual Quality with Emphasis on Spectral Coherence

open access: yesSignals
Distortion of speech in real-life communication is inevitable, affecting its quality. Conventionally, the effectiveness of a speech system in terms of the perceptual quality of the speech it produces has been assessed using a time-consuming subjective ...

FiN‐Kiri: Fabric‐Based Inflatable Kirigami Actuator for Multimodal Soft Robots

open access: yesAdvanced Robotics Research, EarlyView.
This study introduces a type of inflatable fabric‐based kirigami actuator capable of performing bending motion. The actuator is utilized as soft grippers, a crawling robot and a swimming robot. The crawling robot demonstrated extraordinary motion capabilities, such as moving forward, turning and navigating a narrow tunnel.

On Perceptual Distortion Minimization and Nonlinear Least-Squares Frequency Estimation

open access: yes, 2008
— In this paper, we present a framework for perceptual error minimization and sinusoidal frequency estimation based on a new perceptual distortion measure and we state its optimal solution. Using this framework, we relate a number of well-known practical

A Virtual Pipeline for the Evaluation of Optical Distortion in Panelled Glass

open access: yesChallenging Glass Conference Proceedings
Architectural panelled glass lacks an objective method for assessing optical distortion: surface topography captures only reflected flatness (weakly correlated with the through-glass distortion observers report) and visual inspection is neither ...

Predicting weld distortion in the design of automotive components [PDF]

open access: yes, 2007
This project was set up in order to investigate whether it may be valid to use a simplified approach to weld distortion prediction in order to make an assessment of the distortions occurring in a welded structure.
