Article Abstract

Recreating natural organisms' dynamic shape-morphing and adaptive color-changing capabilities in a compact structure poses significant challenges but unlocks unprecedented hybridized robotic-visual applications. Overcoming programmability and predictability obstacles is key to achieving real-time, responsive changes in appearance and functionality, enhancing robot-environment-user interactions in ways previously unattainable. Herein, a Soft Magneto-Mechano-Chromic (SoMMeC) structure comprising a magnetic actuating and a synthetic photonic film, mirroring the intricate color-tuning mechanism of chameleons is devised. A model combining numerical simulation and a strain-dependent color evolution map enables precise predictions and controllable shape-color alterations across various geometrical and magnetization profiles. The SoMMeC exhibits rapid (0.1s), broad (full-visible spectrum), tether-free (remote magnetic manipulation), and programmable (model-guided control) color transformations, surpassing traditional limitations with its real-time response, broad and omnidirectional coloration for enhanced visibility, and robustness against external disturbances. The SoMMeC translates into dynamic advertising iridescence, adaptive camouflage, self-sensing, and multi-level encryption, and transcends traditional robotics by seamlessly blending dynamic movement with nuanced visual changes. It opens up a spectrum of applications that redefine robotic functionality through dynamic appearance modulation, making robotic systems more versatile, adaptive, and suitable for unexplored integrative functions.

Purpose: This study aimed to explore the potential application of NAO in guiding patients through rehabilitative exercises using external audiovisual stimuli, focusing on temporospatial control in terms of range of motion (ROM), execution time and movement smoothness.

Methods: This is a preliminary analysis involving ten healthy volunteers and two patients with shoulder musculoskeletal disorders. The protocol was developed in two phases (III and IV) with different ROM limits and including flexion-extension (FE), external-rotation (ER) and internal-rotation (IR) exercises, performed at two speeds and both with and without NAO assistance.
