Morphological Modulation Enables Adaptive Locomotion in Symmetric Impulse-Driven Robots

Longchuan Li, Yuxi Gao, Yuxuan Xiang, Yuan He, Shufan Chen, Fumihiko Asano +2

RA-L 2026

Impulse-driven limbless robots offer a promising platform for locomotion in environments where body deformation or complex actuation is undesirable. Prior work has shown that symmetric designs can achieve net displacement through temporally asymmetric internal actuation, yet such systems often exhib

When and How to Augment Your Input: Question Routing Helps Balance the Accuracy and Efficiency of Large Language Models

Shufan Chen, He Zheng, Lei Cui

NAACL 2025findings

Although large language models rely on parametric knowledge to achieve exceptional performance across various question-answering tasks, they still face challenges when addressing knowledge-based long-tail questions. Augmented generation techniques, such as chain-of-thought prompting and retrieval au…
