A 3D printing-enabled soft continuum robot with integrated sensing for multi-purpose predictions with machine learning
This paper presents a groundbreaking soft continuum robot that integrates 3D-printed conductive polymer composites (CPCs) for intrinsic strain sensing. Leveraging a Conformer-based neural network, the robot achieves real-time shape reconstruction and object classification, overcoming challenges like material nonlinearity and hysteresis. This self-sensing capability, without external transducers, paves the way for more robust and compliant robots in applications like minimally invasive surgery and industrial inspection.
