Reinforcement learning (RL) has demonstrated remarkable success in text and image generation, yet its potential in 3D generation remains largely unexplored. Existing attempts typically rely on offline direct preference optimization (DPO) method, which suffers from low training efficiency and limited
Passive electric sense, a unique underwater perception ability in aquatic species, enables fish to detect external electrical signals and perform essential life activities in dark or turbid environments. Inspired by the passive electrosensing capability of natural shark, this letter proposes a low-c
Panoptic 3D reconstruction from a monocular video is a fundamental perceptual task in robotic scene understanding. However, existing efforts suffer from inefficiency in terms of inference speed and accuracy, limiting their practical applicability. We present EPRecon, an efficient real-time panoptic
Fish actively control their bodies to interact with the surrounding vortex flow field and generate thrust. Current research on the propulsion mechanisms of robotic fish primarily involves qualitative comparisons of vortex structures from simulations and experiments, lacking quantitative analysis. Th
The development of biomimetics and the demand for higher propulsion efficiency lead to more research in helical propulsion robots. This letter presents a novel sperm-inspired robot that utilizes flexible tail as propulsion and analyzes the motion performance. Firstly, the robot's propulsion system i
This letter presents a novel robotic end-effector for screwing and unscrewing bolts. In many industrial scenarios, it is required to manipulate bolts from the side using robots with end-effectors. Besides, the reaction torque during tightening needs to be balanced to the stability of the robot. To a
To prevent private training data leakage in Federated Learning systems, we propose a novel secure aggregation scheme based on seed homomorphic pseudo-random generator (SHPRG), named SASH. SASH leverages the homomorphic property of SHPRG to simplify the masking and demasking scheme, which for each of…
