A | Citing concerns about the effects of climate change, the International Olympic Committee said Friday it wants to pick two Winter Olympic host cities in July — putting Salt Lake City quickly into play for the 2034 edition.IOC president Thomas Bach said the Olympic body aims to confirm hosts for both the 2030 and 2034 Winter Games at its meeting on the eve of next year's Paris Olympics.Sweden, Switzerland and France have been working on possible bids for the 2030 edition and Salt Lake City officials have long targeted 2034. That would avoid the United States hosting back-to-back Olympics after the 2028 Los Angeles Summer Games.Picking Salt Lake City a decade in advance would give the IOC a trusted partner amid changing weather patterns and also could keep together people who have worked toward bringing the Olympics back the city that hosted the 2002 Games.The double award proposal by the IOC executive board still needs approval by the full membership at the Olympic body's annual meeting, which opens Sunday in Mumbai, India. That should be a formality.The IOC has declining options for Winter Games hosts. Bach noted that only 15 countries on three continents currently meet the criteria of having at least 80% of existing venues for snow sports and a “climate-reliable” outlook to host events in future decades.“We need to address very quickly this dramatic impact of climate change on winter sport,” Bach said in Mumbai. “By 2040, there remain practically just 10 NOCs who could host these snow events.”A likely longer-term project for the IOC is deciding on a rotation policy of a small pool of regular Winter Games hosts.The next deadline for the 2030 and 2034 Olympics will come Nov. 28-Dec. 1 at a board meeting in Paris. A single preferred candidate for each is expected to be chosen and then would enter into exclusive negotiations with the IOC.That is the new process for selecting Olympic host cities and regions, avoiding the once-traditional campaigns and votes which were at risk of vote-buying schemes.The Japanese city of Sapporo, which hosted the 1972 Winter Games, was once favored for the 2030 edition. That bid was officially dropped this week in fallout from criminal investigations and convictions for corruption tied to the Tokyo Olympics in 2021.___AP coverage of the Paris Olympics: https://apnews.com/hub/2024-paris-olympic-games。
IT之家 8 月 22 日消息，由北京市人民政府、中央广播电视总台等单位联合主办的第二届世界人形机器人运动会今天开幕。
B | 本次比赛将持续到 26 日，共设置 51 个项目、1300 多场比赛。今年竞技赛新增跳远、举重、拔河、乒乓球等高强度对抗项目。本届运动会正赛将于 8 月 22 日至 26 日在国家速滑馆“冰丝带”举行，将举行 51 个项目共 1301 场比赛，吸引 666 支队伍携 2056 台机器人参赛，竞赛项目、参赛队伍全面提质扩容。从报名情况来看，各路高手将云集赛场。本届赛事吸引了来自六大洲、16 个国家的 666 支队伍，共有 2056 台机器人同台竞技，队伍数量较首届增长 138%，机器人数量翻了两番。国际方面，美国、德国、日本等机器人传统强国赛队积极参与，巴西还集结了五支机器人足球世界杯队伍，组建起一支国家联队参赛。国内方面，157 家企业、200 所院校和科研机构的 641 支队伍、1975 台机器人齐聚赛场。国内第一梯队企业悉数到场，27 所 985 高校踊跃参赛，产学研用各方力量汇聚一堂。
IT之家从官方介绍获悉，今年赛项从首届的 26 项增加至 51 项，其中竞技赛 30 项、场景赛 21 项；比赛场次从 487 场增至 1301 场。在竞技赛中，今年新增的跳远、举重、拔河、乒乓球等高强度对抗项目，都是对机器人大脑、小脑、本体结构以及核心零部件的极限考验。
C | 赛场上每多跳远 1 厘米、每多举起 1 公斤，都是工程师们对关节电机、减速器不断优化设计、精密加工、测试验证的结果。
D | 此外，田径场比拼将更加激烈，机器人足球比赛将实现带球跑动、大力抽射等技能提升，更有百支队伍上演“舞林争霸”。本届场景赛则将赛项延伸到真实环境，覆盖工业、酒店、家庭、物流等领域，并专门设置了灵巧手赛项。其中，灵巧手设有夹豆子、拧螺丝等 8 个“微操”赛项，上演指尖对决。相比去年场景赛机器人仅“一个人战斗”，本届升级为机器人两两同台比拼，进一步增加赛事的精彩程度和观赏性。
