The ANA Avatar XPRIZE was a four-year competition to develop a robotic "avatar" system to allow a human operator to sense, communicate, and act in a remote environment as though physically present. The competition featured a unique requirement that judges would operate the avatars after less than one hour of training on the human-machine interfaces, and avatar systems were judged on both objective and subjective scoring metrics. This paper presents a unified summary and analysis of the competition from technical, judging, and organizational perspectives. We study the use of telerobotics technologies and innovations pursued by the competing teams in their avatar systems, and correlate the use of these technologies with judges' task performance and subjective survey ratings. It also summarizes perspectives from team leads, judges, and organizers about the competition's execution and impact to inform the future development of telerobotics and telepresence.

翻译：ANA阿凡达XPRIZE是一项为期四年的竞赛，旨在开发一种机器人“化身”系统，使人类操作员能够如同亲临现场般在远程环境中感知、交流并执行操作。该竞赛的独特要求是评审人员需在不到一小时的人机界面培训后操作化身系统，并采用客观与主观评分指标对其进行评估。本文从技术、评审及组织三个维度对竞赛进行了统一总结与分析。我们研究了参赛团队在化身系统中采用的遥操作技术及其创新，并将这些技术的使用与评审人员的任务表现及主观调查评分进行关联分析。此外，本文还汇总了团队负责人、评审人员及组织者关于竞赛执行与影响的观点，为遥操作和远程呈现技术的未来发展提供参考。
