二 |     Israeli officials are planning to ask US President Joe Biden for his formal blessing to provide an Iron Beam laser-based air defense system to Gulf Arab states including the United Arab Emirates and possibly Saudi Arabia, Israel’s Channel 12 has reported.,The unsourced Hebrew-language report, cited by the Times of Israel, indicated the delivery of the system to the Gulf countries would assist with the US-led push to ramp up air defense cooperation between Tel Aviv and a loose regional coalition including Egypt, Jordan, Bahrain, the UAE, Saudi Arabia and Qatar.,The Jewish State does not have formal diplomatic relations with the latter two country, and Riyadh has repeatedly stated that it would not establish formal ties with Israel until the Palestinian question and the creation of a Palestinian state was settled.,On Sunday, the Wall Street Journal reported, citing US and Middle Eastern sources, that the Pentagon had organized a hush-hush meeting in Sharm El Sheikh, Egypt in March to discuss ways to improve air defense cooperation against Iranian ballistic missiles and drones. The meeting was said to have been chaired by then-US Central Command chief Frank McKenzie, and attended by top military commanders from Israel and the Arab countries who were invited.,Israeli Defense Minister Benny Gantz, who announced the formation of a regional anti-Iranian air defense alliance last week, appeared to signal the veracity of WSJ’s reporting on Monday, saying Israel was “building” a “wide partnership with additional countries in the region to ensure a secure, stable and prosperous Middle East,” and that “among other things, this also includes aerial defense.”,Israel Creating 'Middle East Air Defense Alliance' Under US' Wing, Defense Minister Says20 June, 11:03 GMT,“We will strengthen this, as a stable Middle East is an international, regional and Israeli interest of the highest order,” Gantz said.,Iran’s military also appeared to issue an indirect response to WSJ’s report, with Armed Forces Chief of Staff Mohammad Bagheri warning Monday that Tehran “will not tolerate” the threats posed by Israel and its cooperation with CENTCOM, and “will definitely react to them.”,Israel has long touted the purported advanced capabilities of its so-called ‘Iron Beam’ laser-based air defense system, a prototype of which was unveiled last year. Earlier this month, Prime Minister Naftali Bennett said the “game-changer” weapon would shift the balance in Israel’s favor, with the estimated $2 in electricity required per burst to intercept enemy rockets just a drop in the bucket compared to the tens of thousands of dollars a rocket might cost. Bennett expressed hope that the system would come online by 2023.,‘Iron Beam’: Israel’s New Laser Air Defence System ‘Will Bankrupt Enemies’, Bennett Says1 June, 11:44 GMT,Last week, Breaking Defense reported that Israel would ask Biden for more money Iron Beam’s development, on top of the $3.3 billion in annual US subsidies already received by the Israeli military and defense establishment. The outlet’s sources indicated that Israel will likely ask the US president to shell out about $300 million in additional cash.,“The relations between the US and Israel are solid. The issues that will be on the table during the visit are of utmost importance to both the US and Israel. I’m confident that the talks will be fruitful to both sides,” a senior defense source told the outlet.,During his trip to the Middle East next month, Biden is expected to tour an Israeli airbase and get a firsthand look at the prototype laser weapons being developed by Israeli defense giants Rafael and Elbit Systems.,Lasers for use against aircraft, missiles, drones, ships, and ground equipment have been on the drawing board of weapons developers since the Cold War, with engineers spending decades mulling over the prospects of replacing conventional missile and shell projectiles with the futuristic beam pulse. But energy-directed weapons have long faced what have previously been deemed unsolvable issues, such as the immense amounts of power required to operate them, as well as interaction between combat lasers and natural phenomena such as rain, fog, smog or dust, all of which dissipates their strength.,Last month, US weapons maker Raytheon reported that its own laser weapon, fitted aboard an Army Stryker vehicle, had successfully downed incoming mortar rounds in testing.,Raytheon Laser Weapon on Stryker Vehicle Succeeds at Shooting Down Incoming Mortar Shells19 May, 22:19 GMT。本次比赛将持续到 26 日，共设置 51 个项目、1300 多场比赛。今年竞技赛新增跳远、举重、拔河、乒乓球等高强度对抗项目。本届运动会正赛将于 8 月 22 日至 26 日在国家速滑馆“冰丝带”举行，将举行 51 个项目共 1301 场比赛，吸引 666 支队伍携 2056 台机器人参赛，竞赛项目、参赛队伍全面提质扩容。从报名情况来看，各路高手将云集赛场。本届赛事吸引了来自六大洲、16 个国家的 666 支队伍，共有 2056 台机器人同台竞技，队伍数量较首届增长 138%，机器人数量翻了两番。国际方面，美国、德国、日本等机器人传统强国赛队积极参与，巴西还集结了五支机器人足球世界杯队伍，组建起一支国家联队参赛。国内方面，157 家企业、200 所院校和科研机构的 641 支队伍、1975 台机器人齐聚赛场。国内第一梯队企业悉数到场，27 所 985 高校踊跃参赛，产学研用各方力量汇聚一堂。

三 | IT之家从官方介绍获悉，今年赛项从首届的 26 项增加至 51 项，其中竞技赛 30 项、场景赛 21 项；比赛场次从 487 场增至 1301 场。

四 | 在竞技赛中，今年新增的跳远、举重、拔河、乒乓球等高强度对抗项目，都是对机器人大脑、小脑、本体结构以及核心零部件的极限考验。赛场上每多跳远 1 厘米、每多举起 1 公斤，都是工程师们对关节电机、减速器不断优化设计、精密加工、测试验证的结果。此外，田径场比拼将更加激烈，机器人足球比赛将实现带球跑动、大力抽射等技能提升，更有百支队伍上演“舞林争霸”。

五 | 本届场景赛则将赛项延伸到真实环境，覆盖工业、酒店、家庭、物流等领域，并专门设置了灵巧手赛项。

六 | 其中，灵巧手设有夹豆子、拧螺丝等 8 个“微操”赛项，上演指尖对决。相比去年场景赛机器人仅“一个人战斗”，本届升级为机器人两两同台比拼，进一步增加赛事的精彩程度和观赏性。
