MIMO VLC System With Aggregated Angular Diversity Photoresistor Receivers for Misalignment Compensation

Jaeyeong Ha, Jaehyun Park, Yang Huang

TL;DR: This paper proposes a high-reliability MIMO VLC system architecture employing spatially separated receiver units, where each unit utilizes an analog-aggregated angular diversity receiver with a multi-directional photoresistor array, and introduces a current mirror-based analog pre-conditioning circuit.

Visible light communication (VLC) has emerged as a promising technology for next-generation wireless communication systems, particularly for indoor positioning and massive Internet of Things (IoT) networks, due to its immunity to electromagnetic interference and high directivity.…Read more

Agile perceptive multi-skill locomotion for quadrupedal robots in the wild

Jun-Gill Kang, Jaehyun Park, Tae-Gyu Song, Joon-Ha Kim, Seungwoo Hong, Hae-Won Park

Enabling quadrupedal robots to traverse complex terrains-from rugged outdoor environments to urban landscapes-requires seamless integration of multiple motor skills, smooth transitions between gaits, and high-speed perceptive locomotion using only onboard sensors. We present APT-…Read more
