无证之罪

一 |     "A large part of former President Trump's popularity with his supporters is that he fights back against the establishment, whether it be the 'swamp' in Washington, DC, or the political party elites," says Timothy Hagle, a political science professor at the University of Iowa. "He has certainly been speaking out about the raid, but we will have to wait to see if anything comes of it. By that I mean whether there are any charges actually filed. Unlike most Americans, and aside from his media platforms, Trump has the resources to fight what he thinks are unfair actions by the government.",The FBI's unannounced search of Donald Trump's premises in Mar-a-Lago, Florida has reinvigorated his base, a Politico/Morning Consult survey shows. 58 percent of Republican voters said they would vote for the former president if the 2024 Republican presidential primary were today. The share of support is visibly up from 54% in July and 53% in June, according to the pollsters. Likewise, a whopping 71% of GOP voters insist that Trump should run for president in 2024. Moreover, 72% of Republicans said they disagreed with the Mar-a-Lago raid.,Sputnik ExplainsFirst Assange, Now Trump: How Espionage Act of 1917 Became a Political Tool15:16 GMT,The Daily Mail argues, however, that the poll was conducted prior to the release of the FBI's search warrant and receipt, which showed that the bureau took at least 11 sets of classified documents from Trump's Florida house, with the Justice Department having probable cause to carry out the search based on possible Espionage Act abuses.,However, on August 13, Fox News broke that the FBI had allegedly laid their hands on documents shielded by client-attorney and executive privilege, with Donald Trump taking to his social media platform Truth Social and demanding that the documents in question be returned. The president lambasted the bureau for the raid, insisting that it was unnecessary and unjustified given that all documents in his possession were declassified and he and his team were ready to provide access to them any time.,"For the FBI to raid the home of the 45 President of the United States, or any President for that matter, is totally unheard of and unthinkable," Trump wrote on Sunday. "This Break In was a sneak attack on democracy (our Republic!), and was both unannounced and done at a time when the President was not even present.",Trump supporters reacted passionately to the ex-president's posts by rallying outside Mar-a-Lago and Trump's Bedminster, New Jersey golf club. They were seen holding signs reading "Save America" and "You raided the wrong president.",Sputnik ExplainsHow Trump's 2024 Bid & Jan 6 Committee's Effort to Delegitimize Him May Pan Out19 July, 18:41 GMT,Midterm Elections at Stake,The unfolding situation will definitely backfire on the upcoming November midterm elections, according to Hagle.,"The overall effect on the midterm elections will vary depending on how the situation plays out," the political science professor says. "Trump supporters, and Republicans more generally, were already quite motivated to vote in the midterms, but this just intensifies that desire. Democrats were less motivated and the party was desperately searching for something to get their base motivated. Some thought the Supreme Court's abortion decision might do so, but that doesn't seem to have happened beyond a certain group of core voters.",Hagle notes that Democrats were successful with an "anti-Trump" approach in 2020; he believes that they would like to try that again.,"The thinking might be that if Trump is, figuratively, on the ballot it would help them in the midterms," the academic remarks. "I'm not so sure. There may be some who get more motivated with an anti-Trump fervor, but the economy will still be the key for the important voters who are less concerned about politics and more about day to day living.",The FBI raid came after mainstream media reports that Trump may announce his presidential bid in September 2022 or even earlier. Politico and The Washington Post reported in mid-July that the former president had met with top Republican donors, discussing the midterms and a potential 2024 campaign.,The DoJ investigation into Trump triggered speculation that he may announce his new presidential bid very soon, the Daily Mail reports, also referring to a new "campaign-style video" released by the ex-president on his Truth Social platform.,Meanwhile, Republican Senator Rand Paul has called on US lawmakers to repeal the 1917 Espionage Act, after it turned out that the DoJ suspects Trump of violating Section 793 of the law. Section 793 specifically addresses "gathering, transmitting or losing defense information," and also includes refusal to return information that is demanded by the government.,"I don't think it's realistic to suggest that it be repealed," says Hagle. "It's more likely that certain limitations could be placed on it to help prevent the abuses that people perceive are occurring with it.",In addition to that, there are assumptions that the FBI raid was nothing short of a fishing expedition connected to the probe by the House Select Committee on January 6 Attack aimed at delegitimizing him before the 2024 race.,"The Justice Department should 'show that this was not just a fishing expedition, that they had due cause to go in and to do this, that they did exhaust all other means," Republican Senator Mike Rounds told NBC's Meet the Press, suggesting that the release of the FBI's affidavit would help. "And if they can't do that, then we've got a serious problem on our hands."。

二 |       中新社北京8月24日电 (记者 吕少威 陈杭 徐婧)天卓队机器人以9.39秒的成绩打破了9.58秒的人类百米世界纪录;天工Ultra机器人原地跳高跳出2.8843米的成绩,超越了人类男子跳高世界纪录2.45米……  正在北京国家速滑馆“冰丝带”举办的第二届世界人形机器人运动会上,参赛机器人在100米、400米、1500米等多个赛项中接连突破人类生理极限,展现出极强的爆发力与运行稳定性,技术迭代速度远超行业预期。8月22日,北京,第二届世界人形机器人运动会在国家速滑馆“冰丝带”开幕。图为开幕式前进行100米预赛。 中新社记者 韩海丹 摄  其中,北京人形机器人创新中心旗下的机器人堪称“纪录粉碎机”,屡次创造历史性突破。

三 | 截至8月23日的奖牌榜,该中心参赛机器人已斩获5金2银6铜,成为本届赛事焦点。  从去年首届赛事的“蹒跚学步”,到如今“比肩人类”甚至实现超越,短短一年间,人形机器人再次完成对自身极限的突破。

四 |   “今年全行业运动速度整体提升,本质是各厂商机器人本体能力的持续进阶。

五 | ”天工Ultra机器人研发负责人、北京人形机器人创新中心人形部负责人郭宜劼表示,今年关节性能迎来关键升级,转矩和转速均实现大幅提升,这离不开机器人算法学习强化和训练方式迭代。

六 | 同时,机器人电器件的可靠性也得到了系统性增强。  北京人形机器人创新中心运动控制算法专家韩刚表示,天工Ultra的关节力矩上限非常高,已足够用在一辆小型新能源车上。其电容量也非常大,足够支撑奔跑中的高功耗。  在23日进行的400米小型组决赛中,天工Omni机器人以45.66秒的成绩夺冠。

七 | 因其奔跑时躯干前倾、双手收于身前的姿态酷似“害羞捂脸”,被网友戏称为“害羞式跑姿”,迅速在社交平台破圈传播。  “这个跑姿并非趣味性设计,而是性能平衡的结果。”北京人形机器人创新中心运动控制算法专家孟祥向中新社记者表示,团队最初采集了人类跑步数据,但机器人峰值速度接近每秒10米,人类的运动数据已无法覆盖其需求。  为此,技术团队利用机器人腰部关节性能优势,通过大幅扭腰来平衡腿部高速摆动产生的竖直方向重心偏移,确保机器人在高速行进中精准跟踪跑道;而双手置于身前的姿态,则让重心投影更加靠前,形成一种“自己拉着自己跑”的动态平衡,进一步释放冲刺速度上限。

八 | 8月23日晚,北京,第二届世界人形机器人运动会跳远决赛在国家速滑馆举行。图为机器人选手在比赛中。 中新社记者 贾天勇 摄  随着运动速度和强度不断攀升,高负荷下的关节散热是各赛队重点攻坚的方向之一。孟祥说,人形机器人高速奔跑时,髋、踝两大核心关节持续处于峰值输出状态,尤其是高频往复运动的髋关节热量累积最快,是制约长距离竞速成绩的核心因素。  孟祥称,团队针对不同赛距定制差异化的热管理策略。400米短距离竞速主打高速进风被动散热;1500米长距离赛事则搭载专用液冷散热系统,保障关节长时间满负荷输出的稳定性。  针对近期外界热议的“终点撞停”现象,孟祥作出回应:这是竞技场景下的策略性取舍。当前各赛队均以冲线成绩为核心目标,因此普遍选择速度优先的策略,一定程度上牺牲了终点段的刹停距离。

九 |   “事实上,高动态制动技术的研发一直在同步推进。”他表示,极限加速过程中积累的动力学数据,正是优化制动控制算法的核心素材。制动能力对机械设计和控制算法都是极大考验,后续产品迭代中会逐步补齐这一能力短板,实现速度与可控性的平衡。
