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。

二 |     DECATUR, Ga. -- A suburban Atlanta woman has been sentenced to 30 years in prison for the 2021 murder of a 4-month-old who died after she placed him to sleep on his abdomen in the child care center she operated out of her basement.A judge sentenced Amanda Hickey, 48, on Friday after families of children she was accused of abusing gave emotional testimony against her.”I know that there is nothing I can say in words to take away their pain, except take responsibility and express extreme sorrow for what I’ve done,” Hickey told DeKalb County Superior Court Chief Judge LaTisha Dear Jackson, according to The Atlanta Journal-Constitution. “This is my legacy now.”Charlie Cronmiller was being cared for in Hickey's Little Lovey child care center when he died on Feb. 3, 2021. Hickey didn't check on him for more than two hours before finding him covered in vomit and not breathing. The infant was pronounced dead at a hospital.Hickey operated the child care center from the basement of her Dunwoody home. She initially told investigators that she put the baby down on his back, in line with state regulations, but that the child rolled over onto his abdomen. Security video, however, showed Hickey actually placed the infant facedown.Video showed her swinging other babies by their feet, slamming them into the ground, pulling their hair, pushing and tripping toddlers, and placing others in unsafe positions for sleep, prosecutors said. The victims ranged in age from 6 to 18 months.Hickey was licensed to care for six children, but prosecutors said 10 were inside her home the day Charlie died.She pleaded guilty Sept. 22 to seven counts of first-degree child cruelty, seven counts of reckless conduct, one count of second-degree child cruelty and three counts of battery. Hickey entered an Alford plea, which allows a person to maintain her innocence while acknowledging that it is in her best interest to plead guilty to charges of second-degree murder and second-degree child cruelty related to Cronmiller's death. “There is no remorse,” the baby's mother, Stephanie Cronmiller, told the court Friday. “The only thing she’s sorry about is that she got caught. I focus on forgiving myself because I chose her. How could I not think this was my fault?”Hickey was taken into custody immediately after the hearing. Jackson ordered that once Hickey is released from prison, she can’t have contact with the victims or any children younger than 13, and can’t gain financially from the case.。在小型组（身高≤1.4米）400米决赛中，天工Omni以45.66秒的成绩夺冠。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。

三 | ”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。来源/经济日报微信综合中国青年报微信、每日经济新闻微信监制/王玥审核/徐胥编辑/李翱校对/赵阳
