A | Amel Safi did not say goodbye to her brothers before she fled Gaza because it would have made it harder to leave, the 22-year-old Palestinian told ABC News.Following Israel's warning to evacuate northern Gaza Friday ahead of a potential ground incursion, Safi said her mother came to her and asked her to pack her "most precious" items in a small bag and the women in her family went to Khan Yunis, a city in the southern Gaza Strip, while the men stayed behind."I was crying from the moment that my mum told me I have to prepare my bag. I feel like I couldn't talk with my brothers because I'm going to cry more," Safi told ABC News in a Zoom interview on Friday. "I don't want to see them because I know if I have seen them, I would cry more.""I don't like even my enemy to experience such a thing," she added.Safi said she and her family have been living in fear amid Israeli airstrikes retaliating for Hamas' brutal surprise attack last weekend. As of Sunday, at least 2,670 people have been killed and an estimated 9,600 more injured in the strikes in Gaza, according to the Palestinian Ministry of Health."Every single night, every single moment, we are afraid to be bombed, to be killed," Safi said.The Israeli military early Friday told all residents north of Wadi Gaza -- 1.1 million people -- to evacuate their homes within 24 hours and move south. Safi said her family wasn't sure what to do following the notice. Ultimately, the men in her family decided to stay while the women and her youngest brother went to Khan Yunis, where they hoped they would be safer, Safi said."A house that my father built, like he did everything to build, and he tried his best to give us a place to feel safe -- everything in a moment, we may lose it," Safi said. "We are very afraid and we are very sad. I couldn't believe the situation. I couldn't believe it. I feel like, okay, am I dreaming? Am I in a nightmare?"Safi said she's staying at a place in Khan Yunis with between 12 to 15 people. Friends of her siblings asked if they could stay with them but they didn't have enough room. Other evacuees are having trouble finding places to stay and many are sleeping on the streets, she said."You can see women holding their children and they're crying over them," she said. "They can't feed them. They can't find a place to feel safe."They brought food with them, but Safi said the shelves at supermarkets near them are nearly empty."Even if you have the money, you wouldn't be able to buy the things that you really need," she said.In the wake of the evacuation notice, the Israel Defense Forces said Saturday they plan to implement a wide-ranging offensive, including "significant ground operations," and will "broadly attack Gaza City very soon."With her family now separated amid the raging conflict, Safi said she hopes she will get to see her brothers and father again."I will never be able to forget what happened today. It's just a nightmare," she said. "I wish someone can come to me and wake me up."。　　北京8月24日电 (记者徐婧陈杭吕少威)24日，第二届世界人形机器人运动会进入第三个比赛日。三天来，机器人跑百米、翻障碍、踢足球、做家务、搬运货物——从竞技场到生活场，从展示身手到下场干活，一幅人形机器人从“运动员”向“打工人”转变的图景逐渐清晰。8月23日，北京，机器人在太极拳比赛中。当日，第二届世界人形机器人运动会太极拳项目的比赛在北京国家速滑馆举行。　中新社记者贾天勇摄　　组委会委员、中国软件评测中心副主任巩潇在24日举行的媒体吹风会上介绍，当天举行的竞技赛项中，障碍赛包括100米障碍和400米障碍。100米障碍赛设置了10个连续的障碍，包括S弯桥、对称斜坡、螺旋台阶、连续跨栏等；400米障碍赛有16个障碍，包括爬箱子、地网匍匐前进、轮胎阵、梅花桩等更高难度的关卡。　　今年，障碍赛从单赛道变成了双赛道同场竞技，两台机器人并排跑、同时过障。这些赛项不再只是看机器人能跑多快，而是把速度、力量、平衡、抗扰动、全身协调等多种能力放到同一个任务中考察。　　举重项目考察的不只是电机扭矩大不大，还有从末端抓握、关节输出、结构强度，到全身协调和负载状态下动态平衡的一整套能力。机器人把一个重物举起来并保持稳定，实际上要求上肢、躯干和下肢形成比较好的协同。这类能力并不局限于“举重”本身，在实际作业中很多涉及搬、抬、举、放的任务，都需要类似的负载和全身协调能力。

B | 　　当天举行的场景赛有三项。巩潇介绍，工业场景“打包入库岗”，来自真实药厂仓库里的打包流程。

C | 办公场景“综合服务岗”，是一个工作中的常见场景。第一个任务是按照要求在会议桌上摆放桌签、瓶装水和硬板垫；第二个任务是给打印机放纸，并取走打印好的材料；最后把需要销毁的材料分成若干份放入碎纸机内进行碎纸操作，每一件都考验机器人在非结构化环境下的多任务切换和精细操作稳定性。　　新能源充电场景“智慧充电服务岗”同样贴近生活应用。机器人要在30分钟内，为三辆车依次完成充电或拔枪复位的操作。

D | 车辆充电口空间有限，枪头插入时角度稍有偏差就可能插不进去，还要避免刮伤车漆。

E | 机器人在车身旁操作，活动空间本身就不大，需要在受限区域内完成一系列的高精度动作。既考验避障路径规划，又考验对柔性线缆的“理顺”能力，安全性和规范性缺一不可。　　机器人能不能走出“标准答案”的舒适区，在真实、多变的生产生活场景里，把一件小事从头到尾做扎实？巩潇说，赛场既是检验能力的试金石，也是技术进步的方向标。希望大家不只关注谁拿了第一，更关注每一次抓取、每一次插拔、每一次识别背后的算法突破和工程迭代。
