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 ...
