The goal of this project is to develop sustainable, self-aware magnetic soft robots that integrate sensing and actuation capabilities within a single structure. To achieve this, we aim to address two major challenges in magnetic soft robotics: first enabling the precision and adaptability of conventional industrial robots by embedding on-board sensors that perceive actuator states and respond to dynamic environments, and second reducing the ecological impact of magnetic composites by using environmentally responsible materials. This project tackles key materials science challenges through advanced additive manufacturing techniques such as direct ink writing and dispenser printing. By carefully placing hard and soft magnetic powders, we will fabricate components that integrate sensors and actuators into a single part. Achieving seamless integration requires tailoring the manufacturing process to ensure mechanical and magnetic compatibility and to prevent delamination during use. As a proof of concept, we will demonstrate a fully printed, autonomous magnetic lifter equipped with in-built sensors capable of measuring and dynamically adjusting to external magnetic fields and bending angles. In parallel, we will investigate the ecological sustainability of these systems by prioritizing recycled Nd-Fe-B powders and biodegradable or self-healing polymer binders. The project also aims to explore efficient extraction processes and validate reuse strategies for magnetic powders.
