Robot Learns to Communicate via Projected Shadows
A research paper on arXiv (2607.22434) presents a robotic system that uses a 21-degree-of-freedom dexterous hand with compliant soft skin to create dynamic shadow expressions. The soft skin reduces light leakage, producing visually continuous silhouettes. A learned shadow self-model maps the robot's motion to its projected shadow, enabling communication through visual abstractions like shadows, which are distinct from the robot's physical body. This work extends robot communication beyond physical morphology.
