In April 2019,the University of Toronto’s Microrobotics Laboratory published an article on 3D printing microrobots in ScienceRobotics.The researchers embedded particles of the magnetic element neodymium into flexible materials and designed more than two dozen different shapes of magnetic robotic structures through 3D printing technology.The researchers used a pair of powerful magnets to flip the polarity of neodymium in specific parts of the robot,causing them to repel and attract in a magnetic field,and locked the magnetic particles in place with ultraviolet light.Through a specific programming program,the polarity of different parts of the micro-robot is controlled to achieve the motion effects of crawling,creeping,rolling,shrinking,etc.

2019年4月，多伦多大学微型机器人实验室在《ScienceRobotics》刊登了一篇关于3D打印微型机器人的文章。研究人员将磁性元素钕的颗粒嵌入到柔性材料中，并通过3D打印技术设计二十多种不同形状的磁性机器人结构。研究人员使用一对强力的磁铁来翻转机器人特定部位钕的极性，使它们在磁场中发生排斥和吸引作用，并通过紫外线照射将这些磁性粒子锁定在相应的位置。通过特定的编程程序，控制微型机器人不同部位的极性，使其达到爬行、蠕动、翻滚、收缩等运动效果
