Soft Robotics In article number 2205146, Stefano Mariani, Nicola M. Pugno, Barbara Mazzolai, and co-workers develop a seed-inspired soft robot using 4D printed biodegradable polymers. Driven by humidity changes, the artificial seed adapts its morphology to interact with soil roughness and cracks, exploring a sample soil. In perspective, the soft robot shows great potential as a battery-free wireless tool for environmental monitoring.
