Traversing the Narrow Path: A Two-Stage Reinforcement Learning Framework for Humanoid Beam Walking

Kavli Affiliate: Wei Gao | First 5 Authors: TianChen Huang, TianChen Huang, , , | Summary: Traversing narrow paths is challenging for humanoid robots due to the sparse and safety-critical footholds required. Purely template-based or end-to-end reinforcement learning-based methods suffer from such harsh terrains. This paper proposes a two stage training framework for such narrow […]

Deformation Driven Suction Cups: A Mechanics-Based Approach to Wearable Electronics

Kavli Affiliate: Chiara Daraio | First 5 Authors: Seola Lee, Seola Lee, , , | Summary: Wearable electronics are emerging as essential tools for health monitoring, haptic feedback, and human-computer interactions. While stable contact at the device-body interface is critical for these applications, it remains challenging due to the skin’s softness, roughness, and mechanical variability. […]

Super LiDAR Reflectance for Robotic Perception

Kavli Affiliate: Wei Gao | First 5 Authors: Wei Gao, Wei Gao, , , | Summary: Conventionally, human intuition often defines vision as a modality of passive optical sensing, while active optical sensing is typically regarded as measuring rather than the default modality of vision. However, the situation now changes: sensor technologies and data-driven paradigms […]

Derivation from classical Majorana–Bloch equation to quantum von Neumann equation for any angular momenta in coherent states

Kavli Affiliate: Lihong V. Wang | First 5 Authors: Lihong V. Wang, Lihong V. Wang, , , | Summary: After publishing the derivation from the classical Bloch equation to the quantum von Neumann equation to the Schr"odinger–Pauli equation for spin-1/2, we proposed renaming the Bloch equation to the Majorana–Bloch equation because Majorana’s work predated Bloch’s […]

Vector meson dominance in photon structure functions at small $x$ from holography

Kavli Affiliate: Wei Gao | First 5 Authors: Wei Gao, Wei Gao, , , | Summary: We investigate the photon structure functions via the photon-photon and photon-vector meson scattering within the framework of holographic QCD, focusing on the small Bjorken $x$ region and assuming that the Pomeron exchange dominates. The quasi-real photon structure functions are […]
