CETUS: Causal Event-Driven Temporal Modeling with Unified Variable-Rate Scheduling

ICRA 2026poster

Event cameras capture asynchronous pixel-level brightness changes with microsecond temporal resolution, offering unique advantages for high-speed vision tasks. Existing methods often convert event streams into intermediate representations such as frames, voxel grids, or point clouds, which inevitabl…

PERAL: Perception-Aware Motion Control for Passive LiDAR Excitation in Spherical Robots

ICRA 2026poster

Autonomous mobile robots increasingly rely on LiDAR–IMU odometry for navigation and mapping, yet horizontally mounted LiDARs (e.g., MID360) capture limited near-ground returns, reducing terrain awareness and degrading performance in feature-scarce environments. Prior solutions, such as static tilt, …

TGSFormer: Scalable Temporal Gaussian Splatting for Embodied Semantic Scene Completion

CVPR 2026

Embodied 3D Semantic Scene Completion (SSC) infers dense geometry and semantics from continuous egocentric observations. Most existing Gaussian-based methods rely on random initialization of many primitives within predefined spatial bounds, resulting in redundancy and poor scalability to unbounded s
