An AI-Based Curling Game System for Winter Olympics

Abstract

The real-time application of artificial intelligence (AI) technologies in sports is a long-standing challenge owing to large spatial sports field, complexity, and uncertainty of real-world environment, etc. Although some AI-based systems have been applied to sporting events such as tennis, basketball, and football, they are replayed after the game rather than applied in real time. Here, we present an AI-based curling game system, termed CurlingHunter, which can display actual trajectories, predicted trajectories, and house regions of curling during the games via a giant screen in curling stadiums and a live streaming media platform on the internet in real time, so as to assist the game, improve the interest of watching game, help athletes train, etc. We provide a complete description of CurlingHunter’ architecture and a thorough evaluation of its performances and demonstrate that CurlingHunter possesses remarkable real-time performance (~9.005 ms), high accuracy (30±3 cm under measurement distance>20 m), and good stability. CurlingHunter is the first, to the best of our knowledge, real-time system that can assist athletes to compete during the games in the history of sports and has been successfully applied in Winter Olympics and Winter Paralympics. Our work highlights the potential of AI-based systems for real-time applications in sports.

Athlete Perspectives on AI-Driven Coaching Technologies: A Qualitative Inquiry

“…The adaptability of AI technologies across different sporting disciplines, as demonstrated in our study and supported by literature (Bin & Xu, 2021;Shi et al, 2022;Tasiemski et al, 2012), showcases the versatility of AI applications in sports. This versatility allows for customized approaches to training and performance optimization, reflecting the unique needs and requirements of each sport.…”

An Aerial–Aquatic Robot with Tunable Tilting Motors Capable of Multimode Motion

“…Images of the lake, including the aerial, water surface, and underwater environments, were recorded by the robot's onboard camera. [ 40 ] Field experiments demonstrate that the robot can achieve multimode motion with the help of tunable tilting motors and can record movies simultaneously (Movie S7, Supporting Information).…”

Powerful UAV manipulation via bioinspired self-adaptive soft self-contained gripper

“…In the fields of unmanned aerial vehicles (UAVs), aerial transportation and manipulation (1)(2)(3)(4)(5)(6) have drawn more attention because they notably extend the capabilities of UAVs (7), where UAV grasping plays a crucial role (8,9). Numerous studies on UAV grasping (10)(11)(12)(13)(14) have been reported to date, including rigid grippers designed to mimic avian claws (15)(16)(17)(18)(19)(20), achieving grasping by establishing precise dynamic models of the entire system (19,21) or installing a series of sensors on the gripper (20). However, these approaches require complex controllers and heavy rigid grippers.…”
