Abstract

Integrated printing of magnetic soft robots with complex structures using recyclable materials to achieve sustainability of the soft robots remains a persistent challenge. Here, we propose a kind of ferromagnetic fibers that can be used to print soft robots with complex structures. These ferromagnetic fibers are recyclable and can make soft robots sustainable. The ferromagnetic fibers based on thermoplastic polyurethane (TPU)/NdFeB hybrid particles are extruded by an extruder. We use a desktop three-dimensional (3D) printer to demonstrate the feasibility of printing two-dimensional (2D) and complex 3D soft robots. These printed soft robots can be recycled and reprinted into new robots once their tasks are completed. Moreover, these robots show almost no difference in actuation capability compared to prior versions and have new functions. Successful applications include lifting, grasping, and moving objects, and these functions can be operated untethered wirelessly. In addition, the locomotion of the magnetic soft robot in a human stomach model shows the prospect of medical applications. Overall, these fully recyclable ferromagnetic fibers pave the way for printing and reprinting sustainable soft robots while also effectively reducing e-waste and robotics waste materials, which is important for resource conservation and environmental protection.

利用可打印、可回收的铁磁纤维制造可持续、无系链软体机器人
使用可回收材料集成打印具有复杂结构的磁性软机器人,以实现软机器人的可持续发展,仍然是一个长期的挑战。在此,我们提出了一种可用于打印具有复杂结构的软机器人的铁磁纤维。这些铁磁纤维可回收利用,能使软机器人实现可持续发展。基于热塑性聚氨酯(TPU)/钕铁硼混合颗粒的铁磁纤维由挤出机挤出。我们使用台式三维(3D)打印机演示了打印二维(2D)和复杂三维软机器人的可行性。这些打印出来的软体机器人一旦完成任务,就可以回收再打印成新的机器人。此外,这些机器人的执行能力与以前的版本相比几乎没有差别,而且还具有新的功能。成功的应用包括举起、抓取和移动物体,而且这些功能可以在无绳状态下无线操作。此外,磁性软机器人在人体胃部模型中的运动显示了医疗应用的前景。总之,这些完全可回收的铁磁纤维为打印和再打印可持续软机器人铺平了道路,同时还能有效减少电子垃圾和机器人废料,对节约资源和保护环境具有重要意义。
