Design and Control of a Parallel Elastic Actuator With Adjustable Equilibrium Position

Yixi Chen, Evangelos Chatziandreou, Chase W. Mathews, Beau Johnson, David J. Braun

RA-L 2026

We present an adjustable-equilibrium parallel elastic actuator (AE-PEA) that combines a large direct-drive motor (DDM) and a 3D printed torsional spring with a small motor that can continuously adjust the equilibrium position of the actuator. We demonstrate that the AE-PEA achieves high torque contr

Enhancing Kernel Power $K$-means: Scalable and Robust Clustering with Random Fourier Features and Possibilistic Method

Yixi Chen, Weixuan Liang, Tianrui Liu, Jun-Jie Huang, Ao Li, Xueling Zhu +1

AAAI 2026technical

Kernel power k-means (KPKM) leverages a family of means to mitigate local minima issues in kernel k-means. However, KPKM faces two key limitations: (1) the computational burden of the full kernel matrix restricts its use on extensive data, and (2) the lack of authentic centroid-sample assignment lea
