波士頓動力Spot機器人新技能:連續(xù)后空翻,強化學習提升生存能力

   時間:2025-08-29 14:54 來源:ITBEAR作者:唐云澤

波士頓動力公司近期公布了一項令人矚目的技術突破:其明星產品——四足機器人犬Spot,已經成功掌握了連續(xù)后空翻這一高難度動作。這一消息由科技媒體notebookcheck在8月27日率先報道,并附上了一段精彩的演示視頻。

據悉,這一成就并非直接回應客戶的特定需求,而是波士頓動力在探索強化學習技術潛力過程中的意外收獲。公司表示,強化學習訓練不僅讓Spot掌握了后空翻,更重要的是,它顯著提升了機器人在極端情況下的生存能力。例如,在面對跌倒、滑倒或絆倒等突發(fā)狀況時,Spot能夠更迅速地調整姿態(tài),從而有效保護其機身及背部昂貴的傳感器不受損害。

在研發(fā)過程中,波士頓動力的工程師們首先在計算機中模擬了后空翻動作,然后嘗試將這些模擬成果應用到真實的機器人上。然而,據機器人工程師阿倫?庫馬爾介紹,初期的嘗試幾乎每次都以失敗告終。為了減少損壞風險,團隊采取了謹慎的策略,先在體操墊上進行測試,隨著測試的成功,他們逐漸增加挑戰(zhàn)難度,直到Spot能夠在更高風險的環(huán)境中順利完成動作。

令人驚喜的是,Spot在解鎖連續(xù)后空翻這一技能后,其行走姿態(tài)也變得更加自然,更加接近真實四足動物的動作模式。這一變化不僅提升了機器人的運動性能,也為其在未來的應用提供了更廣闊的可能性。

強化學習在這次訓練中扮演了核心角色。通過大量的試錯和反饋調整,Spot逐漸掌握了精確的身體控制能力。這種能力不僅體現(xiàn)在后空翻這一動作上,還體現(xiàn)在機器人對復雜環(huán)境的適應性和穩(wěn)定性上。例如,即使在前腿安裝滾輪的情況下,Spot也能夠保持平衡,展現(xiàn)出強大的運動控制能力。
