央广网北京2月10日消息（总台中国之声记者韩雪莹 江晓晨）据中央广播电视总台中国之声《新闻纵横》报道，提起3D打印技术，相信很多人都不陌 生。3D打印机已经进入寻常百姓家，以实实在在的金属、陶瓷、塑料、砂等不同原材料为"墨水"，在电脑控制下把这些打印材料层层叠加，最终将计算机 上的蓝图变成实物。 学期结束，实验不止。在北京交通大学Rheobot实验室，机械与电子控制工程学院副教授、90后青年科学家李振坤正和同学们一起，用一台桌面级4D打 印机探索流变机器人的更多可能性。精密的喷头遵循编程设定，向外喷射出灰褐色物质，几分钟内，一个简易的流变机器人打印完成。Rheobot团队成员、 北京交通大学硕士研究生徐海天拿起这块约两根手指大小的结构，验证其是否能按预期运动、变形。 徐海天介绍："它是一种非接触式的控制，很适合一些极端的环境，像对狭窄空间的探索、运动，再前沿一点的方向，它甚至可以到人体里面。" 虽有物理阻隔，靠徐海天依托磁场的"隔空"控制，这个流变机器人依然像翅膀一样伸展、折叠。全球第一款流变机器人就诞生在这个实验室。 Rheobot，正是"流变机器人"的英文，这一概念是2023年李振坤根据自主研发的磁控流变 ...
