Multi-bounce Drum Roll with Optimized Active Tricks to Leverage Soft Embodiment
Overview
This paper introduces a soft robotic drummer designed for accurate and efficient drum rolls. It addresses the multi-bounce technique required for high-frequency drumming by leveraging the body's elasticity through two optimized active tricks: Tap-Pull (TP) to increase rebound count and Micro-Pulse (MP) to maintain volume. Using Bayesian optimization, the authors tuned these tricks on a soft robotic system. Evaluation results show that the soft TP trick achieved 12.25 bounces per stroke with uniform intervals, while the soft MP trick provided 6.8-times higher acoustic efficiency compared to its rigid counterpart, demonstrating the potential of combining elasticity and data-driven optimization for complex rhythmic tasks.
