8月23日，第二届世界人形机器人运动会400米决赛开赛。天工队在大型组项目中以38.15秒成绩夺冠，该成绩快于南非运动员范尼凯克在2016年里约奥运会创造的43.03秒世界纪录。    Sidney Powell, one of 18 co-defendants in former President Donald Trump's election interference case in Georgia, has taken a plea deal in which she has agreed to testify in the case.She is pleading guilty to six misdemeanor charges, according to the agreement read in court Thursday. She will get 12 months of probation for each count, as well as a $6,000 fine.As part of the agreement, Powell must "testify truthfully about any co-defendants" involved in the case and "provide all documents to the district attorney's office" relevant to their case against the other co-defendants, according to Fulton County Judge Scott McAfee.Steve Sadow, Trump's lead counsel in the Georgia case, responded to Powell's plea deal by telling ABC News in a statement, "Assuming truthful testimony in the Fulton County case, it will be favorable to my overall defense strategy."Powell's plea comes a day before she was scheduled to go on trial along with co-defendant Kenneth Chesebro.Chesebro, according to sources, last month rejected a similar plea deal with the state, ABC News was first to report yesterday.Regarding Powell's plea deal, former Georgia prosecutor Chris Timmons told ABC News, "From the D.A.'s Office's perspective, it can help them in a number of ways. It focuses the trial to acts that are relevant to Mr. Chesebro. It also means the State's witnesses are facing one cross examination instead of two."Prosecutors accused Powell, a former Trump campaign attorney, of helping tamper with voting machines in Coffee County as part of efforts to overturn the 2020 presidential election.She is not to "have any communication" with any of the co-defendants in the case or members of the media, per the terms of her agreement.She will also have to write an apology letter to the people of the state of Georgia, "which you have already satisfied," McAfee said during Thursday's court proceeding.Powell, Chesebro, Trump, and 16 others pleaded not guilty in August to all charges in a sweeping racketeering indictment for alleged efforts to overturn the results of the 2020 election in the state of Georgia.Powell is the second defendant in the case to strike a plea agreement after Georgia bail bondsman Scott Hall last month took a plea deal in which he pleaded guilty to tampering with voting machine equipment and received probation in exchange for agreeing to testify at the trial of other co-defendants.Chesebro, an attorney, is facing seven counts after prosecutors said he drafted a strategy to use so-called "alternate electors" to prevent Joe Biden from receiving 270 electoral votes in the 2020 election, according to the indictment.Jury selection in his case is scheduled to get underway Friday.。

C | 比赛中，天工Omni跑姿独特，身体前倾、双臂大幅摆动，奔跑过程中做出类似“双手掩面”的害羞动作。相关话题#羞答答的机器人跑了第一#也冲上热搜，引发网友热议。有网友对此评论，“跑得太快，实在不好意思”。赛后，工程师揭秘该机器人“娇羞”跑姿的来源时提到，摆臂太累，它自己选择了“捂脸跑”。“它感觉这样更舒服。

D | ”北京人形机器人创新中心运动控制算法专家韩刚介绍，最初，技术团队给天工Omni按照摆臂跑步姿势设计跑姿，在仿真学习环境中，不断给予机器人奖励，机器人在数据迭代过程中，逐渐形成更舒服的姿势。韩刚进一步解释，机器人如果快速摆臂，肩部的负载能力过大，可能会导致关节发热，影响能耗，无法支撑其跑完400米，“捂脸跑”能帮助机器人在双腿有力、双手舒服的情况下快速跑完400米。
