上半年全球燃油车新车销量占比首度跌破五成

2026年9月，麻省理工学院展示可重新配置的机器人光学实验室。系统能够抓取装在专用外壳中的镜片、反射镜等部件，按照目标布局搭建实验，再以微米尺度调整角度和位置，使激光束达到要求。一次实验结束后，机器人还可以拆下部件，重新组成另一套装置。

研究团队用它自动建立并调试桌面激光腔，同时演示光束居中、多束光对准，以及受到物理扰动后的稳定控制。传统精密光学实验往往需要研究人员反复手动调整，步骤繁琐且耗时；机械操作与自动反馈结合，可以减少这类重复劳动。研究人员正在改进系统感知、运动能力和工作空间，并开发远程访问方式，希望未来让不同地点的科学家提交实验方案，由机器人执行。当前成果主要验证自动搭建与调节能力，尚不是能够自行完成所有科学判断的通用实验室。材料选择、实验问题和结果解释，仍需要研究人员作出专业决定。
