A | Australia’s federal government has declared a natural disaster in 23 flooded areas of New South Wales, which will shore up support for emergency funding. Australian Prime Minister Anthony Albanese announced he would be visiting areas that have been damaged by the flooding along with New South Wales Premier Dominic Perrottet on Wednesday.,At least 50,000 people were warned that they may have to abandon their homes on Tuesday after an initial 32,000 were warned of evacuation on Monday, according to Perrottet.,“This event is far from over. Please don’t be complacent, wherever you are. Please be careful when you’re driving on our roads. There is still substantial risk for flash flooding across our state,” Perrottet said.,Scary! ‘Life-threatening’ floods in Australia's Sydney #flood #sydney #australia pic.twitter.com/NfbQcqR8wT— DNA (@dna) July 4, 2022,Rescue crews in Sydney worked overnight as rivers rose to dangerous levels. At least 100 residents in the city had to be rescued from their cars and homes, according to State Emergency Service manager Ashley Sullivan.,Death Toll From Landslides, Floods in India’s Assam Rises to 179 - Photo, Video4 July, 04:44 GMT,The Bureau of Meteorology (BoM) reported that the storm cell—a cloud made up of an updraft, downdraft, and rain—has brought 31.5 inches of rain over the course of three days in the area of Sydney, well above Australia’s annual average of 20 inches.,Just a few days of heavy rain and here’s the result#Sydneyflood pic.twitter.com/12tYwosgzO— V☭der (@El_Psy_Congro0) July 4, 2022,"The good news is that by tomorrow afternoon, it is looking to be mostly dry but, of course, we are reminding people that these floodwaters will remain very high well after the rain has stopped," said Jonathan How, a meteorologist with BoM.,"There was plenty of rainfall overnight and that is actually seeing some rivers peak for a second time. So you've got to take many days, if not a week, to start to see these floodwaters start to recede," How added.,BoM has also predicted that the storm should move north after Tuesday, and a risk of continued flooding could remain in effect. While Australia is not wholly unfamiliar with extreme weather—with stifling hot summers and below freezing areas in high regions—the country is now experiencing a climate crisis that is causing bushfires, high rainfall, heatwaves and loss of vegetation and wildlife.。
8月25日下午，第二届世界人形机器人运动会在国家速滑馆“冰丝带”迎来拔河项目决赛。山东优宝特智能机器人有限公司的机器人“行者泰山”经过多轮比拼，夺得该项目冠军。这是拔河首次作为正式竞赛项目登上世界人形机器人运动会舞台。这枚金牌，也是山东代表团在本届赛事中的首枚金牌。

新黄河记者了解到，拔河赛项采用二对二模式，两队机器人在宽1.2米、长12米的赛道展开对抗。
B | 单场比赛限时两分钟，率先将绳索中间的红标拉过本方河界的队伍取胜;若两分钟未分胜负，红标偏向一方获胜;红标无位移则重新开赛。赛事按重量分设轻量级(40公斤以下)和重量级(40至80公斤)两个组别。参赛的“行者泰山”机器人重39公斤，参加的是轻量级比赛。
C | 据悉，根据判罚标准，机器人除双脚外任何部位触地或踏出边界即判负;改变体位仅允许垂直纵向移动，严禁旋转身体产生额外扭矩;足底不得加装倒刺、钉跟;比赛过程中因电量不足导致动作失灵同样直接判负。 “很多人觉得拔河简单，不就是往后拽，但放在人形机器人身上，是一件难度极高的事。
D | ”拔河赛项技术代表冯宝运此前介绍，人形机器人脚下只有巴掌大的平面，对手水平拉力会产生巨大倾覆力矩，稍有重心偏移便极易前倾。比赛全程依托AI算法自主完成——机器人需感知拉力变化、调整机身姿态、调控重心平衡，完成智能战术配合。 山东优宝特副总经理周彤介绍，团队为比赛模拟了多种姿态，最终选定模仿人类拔河的侧身姿势。“我们让机器人学会自主拔河，分析对方的力量，然后调整姿态，最后稳定输出。
E | ”记者注意到，优宝特机器人在比赛中始终以侧身的姿态进行对抗。 优宝特成立于2014年，其自主研发的“行者泰山”机器人在2025年首届世界人形机器人运动会上曾获100米表演赛冠军、4×100米接力赛季军。 本届运动会8月22日至26日在“冰丝带”举行，来自全球16个国家的666支队伍、2056台机器人参赛。
F | 拔河作为新增项目，首次亮相便展现了人形机器人在力觉感知、运动控制与自主决策领域的最新突破。
